Which Amp for ML Ascent i?


Greetings!

I just bought the Martin Logan Ascent i. Which amp would you choose from this list:

1. Ayre V5x
2. Plinius SA 102 Mk IV
3. PS Audio Classic 250
4. McIntosh MC 402 (Replaces the MC 352 and sounds just like it.)
5. Theta Dreadnaught II (Two channel configuration)
6. Classe Audio CA 301

My preamp is the Klyne System 7 and my CD player is the Musical Fidelity NuVista 3D. The Klyne is solid state and is voiced like a Conrad-Johnson tubed preamp. The NuVista has an analog-like quality.

I am looking for a smooth, glare free sound on classical and jazz music CDs. I don't want to spend more than $5,100, the price of the McIntosh MC 402. I don't need gobs of power; 120 watts into 8 ohms and 200 into 4 ohms seems to be enough.

Thanks for your help.

Greetings,

I would like to thank you all for answering my post. I appreciate it!

One of the amplifiers on my list has already hit the dust. After carefully reading the reviews about the Plinius, I have decided that that unit maybe too polite sounding for my tastes and that I don't want to deal with its class A output and all the heat it will generate, which could compromise the reliability of the unit over time.

I probably won't go in the direction of Aragon as S7horton suggests for the Martin Logan, and that also includes the very fine amps made by Nelson Pass as suggested by Krelldog. I have a lot of respect for Pass and his gear; he's a great designer. But I'm looking for something a little more warm and rich, even if it means a loss of detail.

When I auditioned the Ascents using a Primare A30 integrated amp (100 watts into 8 ohms and 180 watts into 4 ohms), the sound was precise, detailed, fast, relatively dynamic, and nicely layered from left to right. Soundstage depth could have been a little greater; and there was sufficient body to hold my interest. However, the combination was a little too aggressive and there was too much detail. I could hear the musicians turn the page, shuffle their feet, and squirm in their chairs. When I go to the symphony, I usually don't hear that kind of detail, except for an occasional cough in the audience. So if I were to lose some of that detail, I wouldn't miss it.

Bingaman and Douglikesaudio may be right: the ultimate answer may be tubes. I have just learned that Rogue has introduced a new amp called the Zeus, which produces 200 watts per channel and weighs 200 lbs! And it only costs $6,000, which has to be a bargain for a statement amp! So what I might do is to bi-amp the Ascents using a solid state device for the bass and a tubed unit for the mids and highs. That's a real possibility. But I will need to see if my preamp can handle the two amps and I am going to have to make sure that both amps have the same gain setting, as Martin Logan suggests.

Anyway, thanks for helping an old guy out. I appreciate the feedback. Your suggestions have helped me sort out my amp questions.

Happy listening,
I would suggest reading the article of amps at roger_russell.com. He was the head of McIntosh research for years.
Switching to tubes on my ML Aerius was the most mind-blowing upgrade. Tubes and electrostats are really special together, and worth extra consideration.
ARC VT100 MK3,Worked great on mine so did krell fpb200c .both used are under your price .
Got the MC402 for my Ascents just recently. The stats sang music like never before. Music was warmer, bodied and very musical. I was just astounded by the big improvement.
House of Music in SF had me audtion it at home. IT WAS WORTH every penny.IMO

Good luck.
