Amplifiers:A Keeper for Life. Do you know of one ?
The CAT JL-3 Signatures are the end of the road for me. They are rated at "only" 150w but this is very misleading compared to the rating of many other amplifiers I have tried on . . .
Your most disappointing purchase or audition?
Very tired of the Atma-sphere issue here so I will contribute to the theme of this thread. Major disappointments for me? Thiel 3.6 and 2.3 speakers!!! These were way too . . .
Tube Amp for Martin Logan Speakers

High End Audio-Gaining Higher Ground?
The current crop of high end manufactures sell to an ever decreasing crowd of old fools. This is such a load of BS. I went to the Newport Beach Audio show three times and there. . .
What do you see as the downside of tubes?
This is usually only an issue though in the summer months, as in the winter you will actually appreciate the (rather costly) space heaters! Oh so true with a pair of CAT JL-3's . . .
Review of Dartzeel NHB-108 Amplifier
This is an amplifier I would love to learn more about but with the original review here, and the one in Stereophile, I still have no idea what the sonic strengths are. Ok ok, it . . .

What can you tell me about First Sound pre-amps?
Wow Art, now the CAT? Very cool. You move so fast! 8-) Does your unit also have the phono stage or just a line stage? With all the discussion here with the CAT Ultimate having. . .
Preamp for Aesthetix / Atma-sphere

Audio Research Ref 3 Opinions
Well that must explain why there has been a whole lotta Ref 2's for sale lately! I was wondering it was due to the latest Bose Wave radio that now extends down another half octave. . .

Has anybody heard the new Audio Research LS 27?
Called the Audio Research and they said the new LS 27 sounds better than the Ref 3 and very close to Ref 5. This is a common comment here on A'gon.....the latest LS2X is "better. . .

Giving up on Power Race, and going SET?
Gosh how nice this would be for us Magnepan diehards. But we continue to chase the holy grail of high power amps to get these to sing
As "Aldavis" points out, size and heat indeed. At 145 lbs and 16 power tubes each, with a conservatively rated 150w Class A, the CAT JL-3 monos do a wonderful job . . .
Tube pre-amps $3500 under to add "warmth"

cat jl3 signatures vs. atmashere ma2III's
The Atmashere is lusher and more musical. I am a huge CAT fan but their pre-amp is way better than their amp. The CAT amp is thin and doesn't have any drive. In all the years I . . .
Audio Research LS25 MK II ??
First of all, the LS 15 is very much in the analytical zone of ARC line stages. The LS5 and LS25 in any variations would be a huge step in the right direction in the context of 3-. . .
I need help choosing my next tube preamp.

The use of equipment as "tone controls"
Thanks - sometimes the obvious really does need to be stated. Perhaps, but what is often NOT obvious is how destructive the "obvious solution" can be. A $200-300 . . .
Audio Research Preamp Experts?
If you don't care about phono performance, it makes no sense to chase something like the SP-6, 8 and 10. They were outstanding in their days with phono, but their line stages are . . .

GNSC mods of ARC gear.
I would be very skeptical on the claims that the LS26 is 90+% the performance of the Ref3. If the Ref3's P.S. is tube regulated, this could be a major performance benefit. The . . .

Calling all Aesthetix Callisto / Io Owners
Thank you all for your comments: Nkj: It's unfortunate that the PS's are pinned differently for the Io vs. Callisto. Must be a subtle difference needed between the two products. . .
Sovtek 6550 - Can they really be THIS bad???

Hybrid - Tube / SS amp capable of sub 1 Ohm loads?

Pass Labs versus Jeff Rowland, Audio Research

Best AMP for Avalon Eidolon, ARC, CAT, VAC..?
"Nothing, absolutely nothing, comes close to the transparency, mid-high dynamic contrast (note mid-high only), and most of all, musicality, of the PHI70s." I assume this. . .
Looking for an amp to drive Eidolons Vision.

ARC VTM120 Any thoughts?

Buy an Audio Research SP10 MkII or an SP11 MkII ?
Another vote for the SP-10 if you are dead set on this or the SP-11. I owned the SP-10 for 8 years and loved it, even with its rolled-off frequency extremes, rather high noise . . .
The best hybrid amp?

Sonic Frontiers Line 3 SE vs. BAT VK-31SE
