Solid State Power Amps

@sgordoxyz Is there a reason you want to spend that kind of money? Just because you did does not mean the amps you get would actually sound better. There is something called the Veblen Effect, in which people will spend more under the illusion they are obtaining greater value, which obviously isn't the case.

High end audio is not drive by price, its driven by intention- how much (or how little) the designer wishes to present state of the art.

For example there are class D amps that are less expensive than the amps on your list that sound a lot more like music. So I would consider casting a wider net.

I’ve used McIntosh MC 611 600 W mono amps. I think a pair goes for 15,000.

In the solid state world these amplifiers perform extremely well. And amplifier is reliable.

If I was planning to spend more money I would definitely pursue a tube amplifier and I’m now using one but the 611 is very good

I would look at a VAC tube amplifier and maybe one from Conrad Johnson. I would definitely consider upgrading your pre-amplifier as I read up above. Spending $25,000 for an amplifier is pretty serious and it’s deserving of a higher level preamplifier

Have you considered buying a puppy?

+1 Pass X260.8 monos

This is the best amp I have ever owned.  I have electrostatic speakers that are difficult to power correctly and the 260.8 makes them sing.  

Hello sgordoxyz!  You have chosen well regarded and well reviewed power amps. My I suggest an less expensive alternative.  Starke Sound makes great amps and low prices. I have 5 of their AD320-4 amps and one of the new replacements, the Fiera4. I drive everything from Linkwitz XL521-4s to Magnapans with them. They sound wonderful. 200 wpc, four channels (perfect for the LX521's. Perfect for electronic crossovers feeding a 2 way stereo pair.) The have a decent return policy. I think you will be impressed. I have no connection with the company; I am interested in "the most bang for the buck."  I don't build my onm amps any more. I have two stereo Purii Audio amps, and I prefer the Starkes. You don't need to spend a fortune to have good sound. Enjoy the Music!

NYAL (New York Audio Labs) Moscode 600 uses a tube input/driver stage connected to a Mosfet output stage. 300wpc. I have the Moscode 150 - 75wpc. Designed by George Kaye. Go to the Stereophile archives to read the review of the Moscode 300.
