I used mine with Quad 2805 in a smaller room. It was a great match for that room size. I had Rogue modify my Cronus and it was a really sweet sounding amp for the price.
Rogue Audio Cronus ...what speakers do you love ?
I'm currently using my wonderful Cronus integrated amp to drive my beloved Vandersteen 1C speakers (click on my "system"). Happiness is flowing all around my music room with this combination. Which speakers are you other Cronus owners using ?? What's great about what you now have ?? What are you wishing for with a speaker upgrade ??
