Parasound A21+ or PS Audio S700 monos?

+1 for John Curl’s linear design Parasound A21+

The Parasound A 21+ offers a lot of low-distortion power and isn’t fazed by impedance’s as low as 2 ohms.—John Atkinson

Sounds like the MA gx300’s with ribbon tweeters need some grunt, judging by HiFi News and record Review

"Bear in mind you will need a good amp to drive them."

The Class-D PS Audio doesn’t get a mention into 2ohms in the Stereophile tests, this is usually the case when they fall off a cliff trying to do it.

I have A23 amp, which sounded nice, but man it could heat a room. The A21+ must be a who lot hotter. I had a pair of M700s that I really liked, but my Emerald Physics KCIIs are an easy load. If you’re patient you can pick up a pair at a great price
Underwood HiFi was running a special on Audio Alchemy/Elac amps which should be really good options, and more powerful (I think)

Today is the last day to get the M700 at $1,798 (with qualifying trade-in).Just an FYI

The a21 looks and feels like a much more expensive amp than it is and it the a21+ improves on the originals upper mid and hi fq resolution I would jump on it. My only experience with class D is peachtree tho’ and while they’re smooth I don’t get the listening impression they’re quite there yet.

I know this is a little dated information, I’ve had the original A21, ICEpower amplifiers at the same time, which I’ve seen in at least some PS Audio amps.

I could literally not hear a difference, so I sold the A21.

However, I finally swapped those out for a Luxman integrated, which bested both of them. :)

I did by the way like both the Parasound and the ICEpower amps.  Nothing wrong with them at all, they sound punchy and quiet and warm. Just not as good as the Luxman.
