Description

The Magnepan Altar represents hundreds of hours of research and work.

The Realization of the Altar is a permanent and uncompromising modification to the Magnepan 3.6R.

Triamplification is simply three channels of amplification per speaker, or in the case of the Magnepan 3.6R, one per driver. The lack of passive components (i.e. capacitors and inductors) between the amplifier and the driver results in a true, uncolored sound that few have experienced.

Thank you for looking! I'd be happy to answer any questions about this system or the modifications.

Components Toggle details

    • Magnepan MG-3.6r
    Rewired for triamplification. Each driver is connected to Vampire BPHEX binding posts using Goertz MI1 (custom integrated terminations treated with progold and silclear to prevent oxidization)
    • Audio Concepts Titan II LE
    Very musical sealed enclosure subwoofer. Class AB amp. A perfect match for Magnepan speakers. Connected via direct input (active crossover employs a 45hz fourth-order LP).
    • Quicksilver V4
    I use four of these to drive my midrange panels and ribbons. Two have been upgraded by Response Audio; two are stock.
    • Bryston 7B-SST
    900wpc into 4. In the fashion of obscene overkill, these drive only my bass panels. Probably the best amps for this job.
    • Marchand XM44 4-way crossover
    Highly flexible active crossover used to triamp my speakers and filter the frequencies for the subwoofer (better than the crap xover built into most subs). Currently enjoying 35hz LP, 240hz LR4, 1700hz LR4 filters.
    • Bent Audio TAP-X
    Autoformer-based preamplifier. Probably the last preamp I will ever buy.
    • Marantz SA-11s2
    One of the best SACD players out there!
    • Analysis Plus Crystal Oval
    1m RCA CD player to preamp
    1m XLR preamp to amp

    These cables are highly resolving and neutral. Wonderful match for my system.
    • Analysis Plus Solo Crystal
    4' runs from each monoblock to the speaker. Oh, and locking banana plugs rock. :)
    • VH Audio Flavor 2, 3, 4
    Flavor 4 power cords for the amplifiers and Equitech 2Q; Flavor 3 for the SACD player; Flavor 2 for the active crossover.
    • Mapleshade Samson V1
    I chose Mapleshade primarily for the stunning aesthetics. * Samson V1 stand with extra shelf and riser nuts. * (2) 15" x 18" Amp Stands * (2) 12" x 15" Amp Stands * (1) 18" x 24" x 4" Amp Stand * (2) 15" x 18" Platforms
    • GIK Acoustics Various treatments
    If you have a nice system, you're doing yourself an INCREDIBLY injustice to put it in an untreated room. * 4' x 8' array of D1 diffusion panels (painted to match my apt!) * 4 Tri-Traps stacked floor to ceiling * 244 panels at the sidewall and rear wall first reflection points.
    • Mye Sound MG3.6 aftermarket stands
    These are leagues better than the silly 'T' brackets that Magnepan supplies.
    • RealTraps MicroTraps, MiniTrap HFs
    Used to treat the side wall and rear wall reflections, respectively
    • ASC StudioTrap, SoundPanel
    Additional acoustic treatment for voiced diffusion and absorption
    • Oyaide R1
    Purchased with cryo and burn-in treatment from VH Audio. Outlet cover is Furutech 103
    • Equitech 2Q
    I use two of these: one for the tube amps hooked up to a dedicated 20A circuit, the other for the front-end + Bryston amps. I modified one with 3 x Oyaide R1, 2 x Furutech FP-15a (cu), VH Audio wiring, and no GFCI.
    • Herbie's Audio Lab Iso-Cup / Lampblack footers
    These work wonderfully under my tube amps.
    • Herbie's Audio Lab SuperSonic tube dampers
    I can't live without 'em!
    • Herbie's Audio Lab Grungebuster CD Mat
    I didn't expect too much from this tweak, but I was oh so (happily) wrong.
    • Audio Points 1.5APD
    Used under my power conditioner with Herbie's decoupling grounding base.

Wow, thank you for all the comments! Someday I might replace the internal wiring and build my own 3-way outboard passive crossover. I'd probably also bypass the fuses entirely--I really don't ever listen at levels that high, and my monoblocks can deliver more than adequate power (900wpc) for my needs. If I chicken out, I'll definitely use the isoclean fuses.

The Cardas pins are tempting, but they'd be not too useful if I performed the aforementioned mod.

Persve -- as far as I know, ASC products are available overseas, and I'm almost positive hifi-tuning is based in Germany, so you should have no problems acquiring them.

Rootmann -- glad to hear you got a ported subwoofer to blend with Maggies! I had no luck with a 20-39PC I bought and tried out years ago.

Hi Nils!
Nice system! I had 3a´s and now 3.6´s and just love them. My Mye stands are on the way from Canada and I just installed the Cardas kit! I use BAT VK-40 and VK-500 and I have a great soudstage with fantastic bass, don´t need a sub! But I want to soften up the treble so I´m really intrested in Your room tweaks and fuses! Do You think You can get hold of them in Sweden?
Best regards
Persve ( from Sweden )

Nice system. I have had my 3.5's for many yrs and still LOVE them. I too was thinking of trying some tweaks with the MYE stands and CARDAS jumpers and now based on your suggestions the HiFi tuning fuses. Do you think you could tell a difference with these tweaks if a blind test were done since it's easy to be biased if we know a change was made? I want to try these tweaks but don't just want to throw money away and convince myself that these did make a difference. Also, did you buy the fast-blow fuses and did you consider one's from Isoclean which have a review of making a possibly bigger difference. Your thoughts and of others on the forum appreciated. Thanks.

Nils,

I have 3.6's too and the Grant Mye stands made about as big an improvement as any I'e ever made. I was shocked how focused the sound became when they were put in the stands and coupled to the floor with brass points. I also use Cardas jumpers and Hi-fi fuses like Rv9a, and they clean things up. I run MIT Shotgun S1 bi-wire speaker cables from a McCormack DNA-500 amp and VTL 5.5 Pre, and use an SVS Ultra subwoofer crossed at 40 hz like others here. I recently added a Benchmark DAC 1. I'm hooked on the Maggie sound too and spend too much time listening!!! Nice setup you have going. Enjoy it, as I know you will...

rootmann

hi Nils

Nice system,I also have 3.6 with Mye stands,Cardis jumpers on the crossovers and just recently replaced the fuses with Hi-Fi tuning fuses. The fuses made a big improvement and I would suggest them to all Maggie owners.

Hi Nils,
I am sure your system gives you endless enjoyment!
You might want to check out the Cambridge 840C CD player. My Maggie 3.6's never sounded better. It was a big improvement over the Marantz SA8260. I was going to upgrade to the SA11s1 last summer. I liked the Cambridge better and it just happened to be a couple of grand less.
Thanks for sharing your system on Audiogon!

Hey Nils, tell me in detail what the Mye Stands add and the effects of replacing the steel pins at the external crossover. This appears to be a relatively affordable tweak.

Libertasdon, thank you for the compliments! The acoustic treatment affects every aspect of the sound--timbre, imaging, soundstage... I could go on forever. the many bass traps also cleaned up the bass significantly. I'm glad to hear you enjoy the bass from your 1.6QRs... I found that having a sub even with 3.6Rs is beneficial--just to handle the 20-40hz information (my sub has its 4th-order low-pass filter set at 40hz.

Since my last pictures, I've positioned an ASC StudioTrap (the round tubes) against each GIK tri-trap to absorb some of the high-frequency information and diffuse the rest, which led to a true "disappearing act"--that is, you don't perceive the music as coming from speakers.

Thanks for all the compliments! I am currently enjoying my favorite Christmas CD, Cantante Domino, which is a great recording... :) Happy holidays to everyone.

Good move getting the Mye Stands. They are well worth the investment. They made an immediate difference with my maggies.

Nice system! I love the Black and Maple scheme. I like the acoustic treatments too. Are the tube shaped absorbers behind the rack made by GIK too? Nice.

audiobroke

Hi Nils,

You have a great looking setup. Where did you get the wall treatments? Do they work to your satisfaction? Do they affect the soundstage?

I am currently running 1.6qr's powered by a Mac MC300. The main positive is the full base that can shake things at very modest sound levels. But I am looking for the right 3.6's to bi-amp with another MC300.

Good luck with your tasteful and effective-looking Magnepan Altar.

A well designed system. Looks great and I’m sure it sounds it too.
Good job!

Long live Maggies!

True pillars of affordable good sound!

Steve: The treatments you see in the front of the room are GIK tri-traps in the corners, GIK D1 diffusion panels, and ASC StudioTraps in the middle. On the rear wall, there are ASC SoundPanels and RealTraps HF MiniTraps.

Xagwell: Your system sounds very well-assembled. I do not biwire my speakers, but I do plan to replace those steel jumpers eventually (I'll probably bypass them internally, along with the tweeter attenuators).

Thanks for your comments!

I am another Mag 3.6 owner. I started with the 2.6 quite some years ago. A dedicated room is the dot on the i for me. My system consists of Shelter 90X on a full blown LP-12. Audio Research LS-15/Rhea phono stage. Manley 250 mono's at the bottom. I also employ a Vandersteen 2W sub. I have a CAL Audio CD player/Benchmark DAC 1. My IC's are Transparent Super Balanced. Tell me, have you bi-wired your maggies and if you have ever tried upgrading the jumpers.

xagwell

Sorry if I'm missing it in the thread --- who is the manufacturer of your diffuser / absorber room treatments?
thanks,
steve

Hi Nils, Thanks for the kind words about my system. Regarding the Skylines, through measurement I determined they were not needed in this particular room. In fact, not every treatment I have is in use, only those necessary to smooth out the response and imaging. The Skylines address the highest frequencies through diffusion. This room measured out pretty flat in the higher frequencies. I think the irregular ceiling helped. Thanks, too, for the feedback on the Myes. It seems as though they would tighten up the sound of the Maggies. I've often wondered how much movement -- and accompanying muddying of sound -- is induced by the Maggies' large diaphragms. The stock stands allow quite a bit of wiggle, though I'm sure Magnepan took this into account somewhere.

By the way, you can find my system in "Done for Now", under the title "Sanctum Sanctorum".

I too worship at the Magnepan altar (Hail Magnepan ... Ommmmm). In any event I think you have done a fine job with your system and with your acoustic treatments. I am on my third dedicated listening room (I've moved a bit) and believe there is almost a "toolkit" of treatments which can be applied selectively to different rooms. This looks to me like what you have done. In my case, I have RPG Abfusors and Skyline, plus ASC Bass Traps, Tube Traps and Sound Planks. I have found that these treatments are flexible in their application and address most common room issues. I own the 3.5Rs and am interested in knowing how you find the Mye stands. Have you noticed a significant improvement with them vs. without them? I look forward to your feedback, and, again, nice job!

jtori

Very nice..........Great job with the room treatments as it's difficult combing all the room treatments, system and room furnishings to look good together. Happy Listening!!

jsawhitlock

Nice.

I agree that tweeters on the outside are the way to go, too.

imdoc

Looks great Nils, I'm sure it sounds great too. The stands are a great idea...should be a big upgrade.

Thanks for the comments so far! I ordered a pair of Mye Stands that should be coming any day now, and at some point I might rewire the internals and build a new crossover, but I hesitate to do so at this moment :)

I will look up the Stereo Unlimited folks to see what they can do for me; thank you for the advice.

nils

Hi Nils,
great system. The 3.6's will be my next speakers[I hope!] You should really[and I mean REALLY] check out Stereo Unlimited in Walnut Creek: http://www.stereounlimited.com/Home.htm These guys do Magnepan mod that does not void the waranty from the factory. Plus they have a great line up of tube amps, turntables, subs all kinds of stuff. You can go in there and just sit and listen, it's a pretty laid back in environment plus they are really nice people.

You have to hear the Maggies on some fine tube amps.

Happy listening!
