Yes, I long for a $3000 a pair amp that sounds as good. If Ralph’s amps were made by Kinki Studio they would be around $2500 the pair. Check out:

The Kinki Studio amps are $3500 a pair and sound really good, twice as heavy, twice as powerful, way more parts and great build. Srajen, at 6 moons, uses these as his reference.....2 meg bandwidth.
Maybe when Ralph retires he can make a deal with Kinki or someone and have them cranked out in China....then more of us could enjoy this quality of sound. $5400 is nothing for some but for most audiophiles....still a lot of money. I’ve never bought anything that expensive.
In the meantime you have modded Purifi based amps, and stock or modded GaN amps from Orchard, LSA and Peachtree that are really great.....all way cheaper.
If these amps are better than much more expensive amps....then this is really good. However, a more powerful version has to be in the wings.....100 watts is just not enough for some speaker systems. I would go at least 300/600/1000 watts......of course, even more money ($10K?)......but, again, if they beat the big boys than great.
