Description

Hello all,

My involvement in audio has been an evolving journey for many years now, but about six years ago, I decided a return to Tannoy speakers was something I had to do. I sold my Dynaudio Contour 5.4's, and purchased some HPD 315 drivers and crossovers on Ebay UK.

I had enclosures built in Pennsylvania by Frank Wyatt, of 1 7/8" net MDF (an inner 3/4" laminated to an outer 1 1/8" layer), with a Sapele Pommelle veneer. They are 150 liter bass-reflex, and weigh 192 lbs. each; sans drivers and crossovers.

I built outboard crossovers using Mundorf SIO caps, 12 gauge Alpha core inductors, and Dueland resistors, with silver solid core 14 gauge hookup wire.

I like them so much, they are the speakers I will have till I leave this earth.

After several years with a VPI Scout Signature, I wanted to venture into the idler wheel turntable world, so again on Ebay UK, I bought my Garrard 401, and did a DIY restoration on it. Frank Wyatt built a plinth for me, which I later modified extensively with Purpleheart side pieces (keeping the original 3/8" thick Bubinga center section), and milled Purpleheart edging on the top edges, and framing the Garrard chassis.

I then installed the Dynavector 501 arm (so nice to not have the VPI wobble!). Several cartridges are available in my collection, two Actutex (LPM 415, LPM 320), the Soundsmith retipped Dynavector XX2MKII, Zu Denon 103R with ESCCO white sapphire cantilever and Paratrace stylus mods, which is my favorite by far.

I bought a used Modwright SWP 9.0 SE phono stage, put NOS tubes in it, and installed an upgraded power supply provided by Dan Wright. I feel no compulsion to change to a different phono stage.

I wanted to try a tube line stage, so I sold my much-loved Sonic Euphoria passive, bought a Transcendent Sound Grounded Grid kit, in which I used NOS Amperex 12AU7 tubes, Clarity Caps output caps, Goldpoint stepped attenuator and switching, mil-spec silver hookup wire, and Bent Audio remote volume control. This is an amazing sounding line stage, I see no need to change.

Next came the Assemblage Audio SET 300B, which I sent to Chris Johnson for upgrades, caps and resistors, using Kiwame film resistors, Jupiter Paper Beeswax caps, and Nichicon caps. With the EML XLS 300B tubes the Tannoys sound lush, detailed, and very much like live music, especially well recorded Jazz LPs.

Lastly, some would say I devolved, but to have a quality backup in case of tube failure, and to save hours on the 300B output tubes, I decided to give Class D Audio a try. I bought a 125 Wpc CDA 254 kit a try, and really enjoyed it. I installed an additional amp module in it, running in bridged mono mode, it bumps the output up to 500 Wpc, which snaps the Tannoys to attention, and they sound excellent.

My old five channel amp gave out, so I built another CDA 254 class D amp, with an added module, and I was able to convert it to a three channel amp, with 125 wpc for the surrounds, and 500 watts for the center channel. All in all, a very cost effective set of amplifiers that are every bit as good as some of the higher priced amps I've used over the years.

At this point, at my age ( I turned 70 in February), I am happy to stand pat with what I have, I am enjoying the best sound I've ever had the pleasure of listening to at home.

As of 9/2016, I've completed additional sanding/polishing of the enclosures for my Tannoy HPD 315 drivers. This time, I got it right. Up next, a redo of the Garrard 401 plinth.

Refinishing of the plinth for the Garrard 401 has been completed. Removed face and top pieces, made replacement 1" thick Purpleheart face with inlay, all new top pieces, and new arm board from Purpleheart and Australian Mallee Burl.

Added photos of redone plinth.

Regards, and enjoy,
Dan

Added Benchmark DAC 1 Pre, my digital front end sounds very much improved with this DAC. I know there are better ones available, but not in my price range. May be the best $500 purchase yet. I also discovered how much I was missing with a Musical Fidelity X-CAN driving my Sennheiser HD 600's, they sound amazing, who knew how much I was missing? (Not me!)

Added what is the best line stage I've ever had, the Modwright SWL 9.0. This piece has completed the quest to attain what is my ultimate goal in my system's sound quality. There is now a new liquidity, and completeness to the sound my system never had before. As this category says, "Done For Now", but maybe should be "Done Forever".

Dan

    • Garrard 401 with DIY Plinth
    DIY restoration of a vintage Garrard 401 idler-drive turntable, on which I just completed a six week redo of the custom DIY built plinth, due to problems getting the finish right. I sawed the front off, and removed all the top pieces. A 1" thick slab of Purpleheart with an oval Australian Mallee Burl inlay flanked by a different hardwood species I can't recall were added. A new arm board of Purpleheart and the Mallee Burl was made, and the pivot-to-spindle distance was adjusted to provide for easier cartridge to headshell connections.

    Top pieces were fashioned of Purpleheart, and a new labor-intensive finishing process (new to me, anyway), of Waterlox Tung Oil Sealer/Finish, followed by Waterlox Gloss Tung Oil finish. At least a dozen coats were applied between the two, each coat requiring 24 hours between applications. Thanks to Pierre France for his help in guiding me on the tung oil finish.

    I serviced the motor, cleaning, oiling, and replacing the suspension springs. Glad to finally be done, and finally satisfied. Analog withdrawals were starting to set in, but it now looks better, and sounds better as well.

    If I were to say I am pleased with it, it would be an understatement. For a couple of hundred bucks, it can't be beat. I've hankered for one of these for years now, and thanks to BBtx my needs have been fulfilled.   
    • VH Audio Flavor 2 DIY Power Cord
    Built this AC cord for use with the Transcendent Grounded Grid preamp. Great sounding AC cord.
    • Paul Birkeland 812 Power Amp
    3C24 tube power amplifier changed output tubes to 812. Paul, the designer/builder, brought over four different amp choices to try out on my custom HPD 315 Tannoy speakers. After having problems with 3C24 tubes, Paul changed the amplifier to run 812 output tubes.

    The amp sounds much better, more powerful, and I like it even better now. My thanks to Paul Birkeland!
    • Audio Assemblage (Sonic Frontiers) SET 300B
    300B SET Factory Upgraded, with EML XLS 300B Tubes. Just serviced by Paul Birkeland. All critical measurements were taken, two bad Blackgate bypass caps were replaced with higher-rated Nichicon caps, and the filament voltage was optimized to better suit the EML XLS 300B tubes.

    This amp now sounds incredible. Paul informed me the transformers in this amp are Magnaquest, to him about as good as you can get. He also informed me this amp sounds as good as any $5000 SET 300B amp available in today's market.

    • Musical Surroundings Fosgometer
    Azimuth adjustment tool.
    • Custom built crossovers Custom DIY
    I've just completed an update on the crossovers for the custom HPD drivers. I actually used all the parts over again, including much of the solid silver hook-up wire. I made new mounting boards, and ran the wiring under the board, for a much cleaner look. I used heavy copper terminal lugs, which I modified to use a flat male spade connector, rather than wire. Wire runs are much shorter as well.

    I made new outlet cables, using Furutech locking bananas, and Cardas binding posts. I can't tell why, but this update improved the sound of these speakers much more than I expected. I've never heard electric guitar sound as it did on Steve Cropper and Felix Caviliere's "Nudge It Up A Notch", Cropper's guitar sounding just as he had wanted it to sound, with gorgeous tone, unlike anything I've heard before on a recording.

    Next is an internal speaker wiring update.

    I've just completed changing some components in the crossovers back to their original values. 27ohm resistors changed back to 47ohm, .68mh inductors reverted back to the original .82mh. I'm beyond pleased.
    • Tannoy HPD 315 w/Hard Edge Conversion
    Twelve inch Dual Concentric HPD driver in custom enclosure.1 7/8" wall thickness with custom designed and built crossovers. Weight is 200lbs. each. Finished in Pommelle Sapele.

    A complete rewire of the internal wiring was just completed. I made a 1/4" X 1/2" Teflon terminal board, with double-ended male spade connectors at the speaker. Wiring was completed at the input end with new crimped and silver soldered connectors with color-coded heat shrink tubing, and color-coded electricians tape.

    The results are a major improvement in clarity, detail and dynamics. These great speakers have just gotten much better at the things I love about them.

    After further study of fine wood finishing methods, and purchase of additional sanding/polishing medium, I again sanded and polished the enclosures for my Tannoy HPD 315 drivers. Got it right this time, now they are done. Next is the plinth for the Garrard 401.

    Some of you may recall my changing resistor values in my Tannoys back to the original value, to good effect. In that same vein, I just modified the .68mh inductors back to their original value of .82mh. I felt at the time when the crossovers were first built, the high frequency output was out of line, so I reduced it to better suit how my system sounded at the time.

    I had saved the .82mh Alpha Core ribbon inductors, and I changed them out yesterday. The results have shown me how much my system, as a whole, has improved, due to how well it sounds now as opposed to back 8-10 years ago. I feel I'm now getting what I was supposed be hearing all along. It's a great feeling. Now I no longer wonder what Dr. Arthur Loesch was thinking when he gave me this crossover design so many years ago now.

    Dan
    • Townshend Audio Number Four Size Seismic Podium
    Large Podium to fit under my 200lb. Custom Tannoy speakers. They are 17" W X 20" D X 48" H.

    These isolation podiums have made my speakers sound as never before. Just better wouldn't describe it. I have never before heard anything sound this way in this room, or perhaps any room I have visited.

    These Seismic Isolation Podiums are very special in what they do. They're expensive, but worth it for what they do for speaker systems. 
    • KEF Q 650c
    Newly added Kef Q 650c center channel to upgrade from my old Kef Reference 100 Center Channel speaker. The Q 650c is all I could have wanted or hoped for. Multi-channel music is way better now, as is Home Theater listening.

Thanks Charles,

I feel that I have truly reached my goal of the kind of connection to music that I was looking for, all those years ago. It took SET to make finally it happen, thanks to folks like you, and I have to include Art Dudley here, as he was the first to twist my knickers about tubes.

I also have him to blame for my venture into restoring and using the Garrard 401. Curiosity is a dangerous thing, but it can lead to very good outcomes.

I'm hearing improvement from the Assemblge SET 300B, due to new caps and resistors settling in. I have trouble describing this, just more emotional connection with the music.

Solo piano, at near concert hall sound levels, with no discernable distortion present. Lovely.

System edited: I got my Zu Denon 103R back from ESCCO yesterday, where it had their sapphire cantilever and Paratrace stylus upgrade. After the truama of mounting and setting it up, I found the upgrade makes this venerable cartridge among the best I've had the pleasure of hearing. Much improved inner detail, and it rides much quieter in the groove than I recall it doing before. Very pleased, and impressed. Thanks goes out to Spiritofmusic for his recommendation of this upgrade! Best regards, enjoy, Dan

Charles,

Thanks for your comments, I really am in a happy place regarding my system, and listening in general.

As it turns out, both camps are right regarding Tannoy and amplification. At one time, I was using a modified 300 Wpc Aragon on my HPD's, and they sounded quite good.

However, at this time, I prefer the SET 300B. It offers nearly the dynamics of the SS amps, but as you know, the SET 300B is in a class by itself for sheer musicality.

Best regards,
Dan

islandmandan

Dan,
It`s gratifying to read that someone is genuinely happy with their audio system and simply enjoys the music .Reading this and other forums you come to realize this isn`t the case for some. Tannoys seem to generate two camps, SET amps are terrific with them, or Tannoys need more power than a low powered SET provides. Maybe it depends on the specific Tannoy model.Bottom line, I`m glad it worked out so well for you using a lower power SET amplifier.You took the chance and the result speaks for itself.

Thanks Arj, I'm glad you noticed! I've been in this hobby a long time, but I didn't really get serious until I was getting close to retirement.

I realized in order to have the kind of system I wanted, it had to be done before I retired. So, I sold my Dynaudio Contour 5.4 speakers, and bought my Tannoy drivers on Ebay UK.

I wanted to make them as good as I could possibly make them, as I know from a past DIY effort with 12" MG's, if the enclosures are inadequate, the speakers will never sound as good as they could, but it had to be done on a small budget.

One of the motivating factors was, I wanted speakers that could be driven with low-power SET amplification.

I was lucky enough to get to know a friend of Dr. Arthur Loesch, and he got the good doctor to design my crossovers for me. It has been a great experience in the last few years, and the result of the process is, I get to enjoy the most rewarding listening I've had in forty years.

I finally no longer have the need to upgrade, and it's a good feeling.

Thanks and regards,
Dan

System edited: Zu Denon 103R is being shipped back today from ESCCO, where it had their white sapphire/Paratrace stylus upgrade. It should make for a substantial improvement on an already very good cartridge.

islandmandan

Hey Dan, the more I read through the system the more impressive it looks !
I see you are using the MintLP. I too have one but have never had the patience to go through fully...just use it like a basic protractor

Also once your Zu comes in, you must try a wooden headshell at some point. would be interested in your opinion on that

Cheers !

I had been troubled for some time by a mechanical-sounding hum heard from my speakers, being generated by my Garrard 401, which I took to be motor noise being transferred to the plinth.

After investigating, I discovered it was not motor noise at all, but due to a poor ground connection at the main arm. I disassembeled the arm enough to check the wiring, and the only place I found that could possibly be the problem, was the afore-mentioned main arm ground connection, which is connected to the anti-skate fastening nut on the arm underside.

While not exactly loose, a good connection was not being made due to the arm's paint. After a proper tightening, I am quite pleased to report there is blessed quiet now, especially in those quiet areas of recordings.

Quite a relief to finally eliminate this noise. I had at one time thought I'd have to remove the turntable chassis, and look for an area where the motor was contacting the plinth.

What a blessed relief!

Cheers,
Dan

What cart did you have them do for you?

Hi Dan - My trusty Benz Micro MC3. I had plans on nuding it but SS strongly advised not to do this as it then becomes a beacon for microscopic crap floating in the air. Much of this dust is metallic particles. I found their comments interesting.

Hi Chris,

We've had a beautiful summer here in the Pacific Northwest (sometimes, it seems as if we don't have summer).

The music is sounding it's all-time best (especially analog). I'm really impressed with Soundsmith's retip of the XX2MKII.

What cart did you have them do for you?

Regards,
Dan

islandmandan

Hi Dan
I find once I settle into a cartridge I tend to leave it alone for quite some time and listen to record after record. I received a retip back from SS two months ago and still have not listened to it yet. Maybe I am just lazy. But lots of summer travel in there too. As I type this now your post has made me think of switching. :^)

Good to see you enjoying the tunes. Hope you’re enjoying summer

Cheers Chris

System edited: The Dynavector Soundsmith-retipped XX2MKII has really settled in nicely, I haven't felt the urge to use another cartridge since it returned from Soundsmith. Still waiting on the ESCCO-modified Zu Denon 103R, which I sent in at the end of May. They say another 2-3 weeks yet, I'll be interested to compare it against the Dynavector.

System edited: My Dynavector XX2MKII cartridge just returned from Soundsmith, where it had their top OCL re-tip. After the first few hours, I have concluded it's now my best cartridge, but that may change when my Zu Denon 103R returns from ESCCO with its upgrades.

Pradeep,

Thanks for the update, I'm glad you're enjoying your 401 so much.

As I mentioned before, try the platter dampening rings avaiable on Ebay. I do think the copper mat helps dampen ringing on the platter, rather than exacerbate it.

Things like alternative mats are generally rather inexpensive to try, and easy to resort back to the original. Just have fun with it!

Regards,
Dan

islandmandan

Hi Dan and Chris
Many thanks for your suggestions and comments.
My 401 is in pretty good shape though the cosmetics could be better. The original rubber mat is usable. I am a bit sceptical about ditching the rubber mat and opting for a metallic mat with a metal on metal contact . This could lead to ringing etc. I intend to get one of those heavy record clamps from TTWeights when my daughter visits from the US in August . I love the look of the almost gold like sheen on Dan's copper mat. Will check the UK site.
The 401 is sounding embarrassingly good. The SPU has less than 10 hrs on it. What do you reckon is the minimum breakin for a new cart ? At least 25 hrs would be my guess.
Will get to mount the Miyajima mono cart today as the Best LP protractor arrived last night.
Cheers and Happy Listening
Pradeep
