I have a 335 with B&W N802. I used to own a KSA200S. Funnily, unlike egrady, I found 335 much more detailed than 200S. But then, it can be due to my room, cables, etc. I fully agree with Doug that cables make a world of difference. So, while contemplating which amp, put aside some $$$ for cables.
Levinson
I am considering getting a Levinson 335 stereo amp, but I have read many posts implying that an FPB 200/300 is far better than the Levinson 335. Due to where I live I don't have a real chance to do a good in-home comparison of both amp so I have to rely on external reviews and users. Thanks for your help MD
