I own one and it is about my 20th amp over the years. I worked in audio in the 80's and I've heard many more. There is nothing dry or grainy about this amp. Carver haters usually have not actually heard one. Mine has been serviced properly by a Carversite tech. I bought it non-functioning. I've also owned a pair of Carver 9t monoblocks and several other Carver amps. Here is the scoop, it excels in all of the typical amplifier jargon for sound quality like "soundstage, bottom end, sparkle" etc. The Sig 600 is the cats meow. There is nothing I can criticize about it other than it has no power switch (so what). Where it shines (like many Carver designs) is in the ability to drive speakers well. The total absence of clipping distortion is readily apparent and a revelation for those lucky enough to listen to one. The Sig in particular will drive any speaker and not break a sweat. It doesn't even get warm. It is a total monster. Also, having gobs of headroom will make many speakers "open up". Although tons of power are always on tap, it does so with a sweet demeanor. Delicate sounds are perfect. I would put my Sig against any amp at any price in a blind test. My Sig recently went up against a Pass Labs XA 200.8 https://www.passlabs.com/products/xa200-8/ and the owner was spooked that the Sunfire went toe to toe with his huge Class A monos and HAD MORE POWER. A lot more. People may prefer a different amp for many reasons but it's usually just bias. Am I biased? Yep! How can I possibly improve an amp that sounds fantastic and will control any speaker the future will throw at it with ease. You can't go wrong if you can find one. I'm never selling mine.
