For HT usage, there is no difference. Or at least I didn't notice. I tried the D-Sonic on my mains and the sound was amazing. I decided to switch back to my Krell so the front 3 would be matching. And for music, I feel that the Krell sounded a little more full....but I also might be biased haha. The D-Sonic is really good amp, and has a ton of power. I felt that the bass response was very good from both, and I had no complains with using it. I just want to go to a single box solution.How would you compare the sound of the two? I’m looking at both of your ads.
