Red Dragon Audio, Still in business?

I don’t have experience with their 3+ channel amps but from what I’ve gathered they are not quite as well regarded as the 2-channel models. 

Very good advice thanks, didn’t  know that about the early A21 amps. The Music Room has a lot of Parasound amps flow through their hands, and they’re authorized dealers, so I like that. My a/b alternative was going to be Parasound if I didn’t get the Red Dragons, or another class d. How about their multi channel amps? Are they worth it….like the A31…..or better to stay with 2 or 1 channels?

Since you like Parasound amps and want to save some coin, I highly recommend seeking out an original Halo A21 amplifier, preferably one of the later production units so it’s no more than a few years old (a serial number in the six thousand range).

The A21 actually measures better (lower noise and distortion) than the newer 21+ despite the spec sheet claims. The difference is audible too. I actually prefer my late production A21 to the $6800 Coda No.8 V1 that I owned previously. The primary distortion of the A21 is second harmonic which is very uncommon for solid state. 

The A21 mated to a highly transparent preamp such as the Benchmark LA4 or Topping A90D makes for great synergy. 

I would too actually, so I agree. I love paramound amps. I was trying to save a little coin though, and the reviews I’ve read were good enough to try them out.
Strangely enough, even though you say they’re out of business, they are still selling the m1000 amps, at a reduced price. They’ve gotten good reviews on Audioholics.

Last I knew, they had shut down a long while ago. But their website does show a 2024 copyright.

Have you ever lived with a high “power” class D amplifier? I ask because 500 WpC of Class D will tend to perform more like 100 WpC of class AB in practice. They tend to struggle with dynamic loads (which speakers are of course) in my experience. 
 

I would take a 300 WpC class AB Parasound amp over any class D amp of any power rating.
