Charles have you tried or heard any good class d amp setups in recent years?

I'd be interested in your observations regarding how a good class d amp setup might compare to a good set based one.

Class d has really won me over. It's a totally different beast than any comparable class a/b ss amp. Class a is a different story as well tube or otherwise. I'd be much quicker to jump on the tube amp bandwagon I think if not for class d. I think it has hit its stride recently for "high end" home audio and still has huge upside down the road as well.

I had a class g amp as well a bit back. That one never quite seemed to fire on all burners properly in my experience.

Hi Cal,
It goes against common wisdom(stereotype) but I get more information/resolution from this SET than any other amplifier I've had in my system. If you ever come across a used pair of EML XLS tubes I'd suggest you take a chance on them. It's a superb match with the Frankenstein. To say the Super Eclipse images better than your former Thiels is quite a compliment.
Charles,

Hi Charles, a response to your question in the Thiel thread (http://forum.audiogon.com/cgi-bin/fr.pl?cspkr&1424398773) in regard to the Coincident system being "hotter" than the Thiel/Pass combo.

I think your comment was right on. The Coincident combo (SEIIIs and Franks; Psvane 300B-TII) is actually producing more information in the high frequencies and therefor is simply more revealing that the 2.4s. I've spent many hours playing with placement. For example, before I got the Franks, I had to put a lot of work into getting further away from the SEs because of the high frequency hottness and the difficulty in integrating that information. Once I got the Franks, I was able to pull speakers out from the wall more. I've also worked on toe-in a great deal, especially since I'm used to almost none with the Thiels. Currently I'm pointing them at the arm rests of my three person couch where the middle seat is the sweet spot.

Anyway, I find that the SEIIIs actually image better that the Thiels. The only time I miss the old combo is on certain female voices (Alison Kraus, Rhye) where the old combo's increased sweetness made the women slightly more intoxicating.

Two more CDs that I may have mentioned before that I listen to often.
1)" Look Stop And Listen" Pianist Tardo Hammer playing the music composed by Tadd Dameron. Beautiful!
2)"The Great American Song Book" Carmen McRae. Live jazz club 1971 in LA. Joe Pass on guitar. Beautiful!

charles1dad February 13, 2015 02:37

Fellow jazz lovers, here are a few CDs you may enjoy as much as I do.

1)"Very Tall" Oscar Peterson trio with Milt Jackson. No description necessary.
2)"Bean Bags" Coleman Hawkins and Milt Jackson. Ditto!
3)"Live At The Jazz Standard" Russell Malone. Beautiful.
4)"Tribute To Paul Desmond" Bruce Babad. Babad can play!
5)"Takin' It There" Graham Decker. Young guitarist with mature chops.
6)"But Beautiful" Kenny Barron and Joe Locke. Piano and vibraphone duet by two masters of their instruments. The title is self explanatory.

Hi Thalusa,
Just as I thought, both are excellent in their own beautiful way. No amplifier will be perfect but either of these two will bring joy into your audio system with the right matching speaker. You have the right speakers for both of these amplifiers.
Charles,

Hi Charles,

Thank you for the compliment regarding my amplifiers. You are a true gentleman.

I am really enjoying switching back and forth between the Franks and my OTL amp. The Canary is on the sideline for now; it does sound closer to the Franks than the Joule. You are right, they are different presentations, both very enjoyable. The biggest difference is that the Joule, with its 8 output tubes and 80 watts a channel, sounds bigger and weightier, especially with bass notes, and the highs have a velvety richness to them that I find very enchanting. The Franks are noticeably clearer and more transparent, and I am finding the dynamics to be more startling than the Joule. Funny thing is the Franks sound a lot like what I imagine a great OTL would sound like, and I imagine the Joule has qualities that are a lot like a SET amp.

I bought the Franks because I wanted something that puts out less heat and is mechanically more quiet than the Joule. My intent was to sell the Joule if I liked the Franks, but I have been really enjoying switching back and forth. Then there are days like in the past week where I can sense the bass and treble ripen with the Franks, which has got me thinking I could easily live with just the Franks and sell the Joule. It's been fun.

Rebbi, I think your audio dilemmas will be trending on the internet shortly, soon to replace Kim Kardasian and her unique assets for the better. :^)

mapman February 06, 2015 18:03

Hmm, as I recall, the Decapos made a similar difference as well at first, right Reb?

Like I said its fun to try new things. Its relatively easy to do in audio. I sometimes wish I did not like my setup as much as I do so that I could have some fun with new toys, but I keep choosing to just enjoy the music, for now.

mapman February 06, 2015 18:01

Bill,
If you read Rebbi's blog notes the good far outweigh the bad in an overall sense. He's getting the best sound he's ever had at home with this amplifier. I'd keep the amp and replace the speakers at some point.
The amp has made the bigger difference in his system rather than the De Capos.
Charles,

charles1dad February 06, 2015 17:58

On the other hand, they are only speakers. There are many nice sounding speakers in the sea. You just gotta find teh right one (to fit in with your needs). Its fun trying new things. If it doesn't work out just sell again and move on. The worse thing that can happen at each stage is that it likely sounds very good but not perfect. Oh well. That should be the worse thing that happens to us. :^)

mapman February 06, 2015 17:57

Rebbi, I think your experience in soliciting advice on the SET amp, and the outcome of the build, again underscores the necessity of an in home trial. Though you have fallen in love with the new amp,it is not working in your room with your music with your speakers. I waited a long time for my Triumph extreme IIs to come up for sale. I love them, but what does that mean for you? I also love the decapos driven by my 8 wpc Dynamo. Your 300B AN isn't getting it done with the decapos. You took a chance with the amp, but it may be hard to take chances on speakers and stay revenue neutral.

brownsfan February 06, 2015 17:39

Rebbi,
Nice listening notes, you nailed the essence of what makes good SET amplifiers so musically honest and emotionally involving. +1 for your descriptive comments. Your Manley was no slouch but you've moved beyond that level with your new amplifier.

charles1dad February 06, 2015 14:26

Charles, I am not sure if the term easier is the correct description, but the TE excel at lower level dynamics and detail. With the Triumphs, I found that I needed to play them louder to get that "jump" factor. I also found that the De Capo also excelled at low level dynamics.

brf February 06, 2015 14:15

Hi Brf,
I'm glad the Duelund CAST capacitors worked out so well for you as they did for me. Brf I wonder if the larger Total Eclispe is an easier speaker load than the Triumph MK I? My 8 watt amp drives them with a sense of ease and flow.

charles1dad February 06, 2015 14:02

I'm starting to share listening impressions of the Kit 1 on my blog. Enjoy!

rebbi February 06, 2015 13:48

Hi Thaluza,
I find your joy with the Frankenstein very intersting for the following reasons. You already owned two "fine" power amplifiers, the Canary 300b push pull and the Joule VZN 80 MK V OTL. I thought there might be an adjustment period to a different topology. Do you plan to keep the Joule to use as an alternative flavor from time to time? It seems the Joule and Frankenstein would both provide much fun with their different presentations. You have certainly owned some excellent power amplifiers.
Charles,

charles1dad February 06, 2015 13:47

For point of reference, both the Triumph and Reference 3a de capo i where used in a secondary system driven by a Cary Integrated 300 SEI with EML 300 XLS tubes with the only source being a Squeezebox Touch /Oppo combo for streaming audio.

In my main system, I still use Coincident Total Eclipse speakers with the "Charles1dad" recommended Duelund cap upgrade. I am not looking for a speaker change.

brf February 06, 2015 13:33

"When two credible perspectives are so polar it makes me wonder what accounts for the wide gap."

No two cases are exactly the same. It is always interesting to learn about how different people react to similar experiences and try to figure out why.

mapman February 06, 2015 13:07

Mapman,
I've developed respect for the input and impressions provided by Brownsfan and Brf over the years. For certain there will always be contrary opinions in this field of High End audio. When two credible perspectives are so polar it makes me wonder what accounts for the wide gap. It's as if Brf saw yellow and Brownnsfan said no the color was dark purple when describing the same object.

charles1dad February 06, 2015 13:03

I have to admit I am very ambivalent when it comes to technology. I am always interested to see how new innovations like Class D amps fare up against the older competition with more of a proven track record. I am interested in all technology old and new. I would love to own a modern Victrola in good working order for example. There is an old fashioned general store nearby whose owner refurbishes and sells Victrolas. They sound lovely playing in there! I will own one someday. Maybe a SET as well. :^)

mapman February 06, 2015 12:56

Dan, thanks for that. I am interested to hear how it works out.

mapman February 06, 2015 12:51

Mapman, as I noted in my own system thread, I am currently building a Class D CDA 254L amp, which I will be using as an alternative, and back-up, to the SET 300B that works so well with my HPD Tannoys.

It will be an efficient, high-power amp, that if it works out like I hope it will, will allow me to sell off my First Watt M2 (which I actually also love), but the Class D will provide a near 180 degree change in power amp topology, and much more readily reflect the difference in how my speakers respond to differences in the amount, and type, of power they are being driven with.

Should prove interesting.

Regards,
Dan

"There always seem to be differences when it comes to comparing audio components."

You can bank on that! Just like taxes and the other thing. :^)

The other thing one can bank on is it always pays to do the homework up front which includes sampling a lot of information and individual viewpoints.

mapman February 06, 2015 12:37

There must be significant changes between the Triumph MK I and the MK II, Brf's finding is the opposite of Brownsfan who currently has both the DeCapo and Triumph MK II. There always seem to be differences when it comes to comparing audio components.
