Speaking of sound on the TA30, I just got mine 2 weeks ago. I had the EL34's changed to KT88's. I enjoy the sound but find the bass still a little too loose. I am using them on my Apogee Centaur Majors ( small listening room, 12 x 12 ), am I asking too much from this intergrated? I understand there is a break in period but my SS conrad johnson's sonographe sounded a lot better so far. Looks like the Apogees, even though they are Hybrid might be a little took much for the Cayin to drive. Thanks, John
