CAV-50 and 804 Diamonds

I am demoing B&W 804 Diamonds. I have a Conrad Johnson CAV-50 and pretty sure it's not a good match. I'm having to constantly bias the tubes and unless I get it right it produces a fairly grainy sound at volume. The 804's need WPC of 50-200, while the CAV-50 produces 50 WPC I'm replacing Coincident floor standers which is a fairly efficient speaker. I really want to stick with the 804s. I guess the point is I'd like comments on match with the CAV-50 and/or what would you replace it with. Thanks

The CJ CAV-50 is the 40W per channel Ultralinear integrated.
To get it "up to par" with speakers worthy of diamond tweeters you need to sink in major $$$ to redo the power supply.

Do you want to stick with Integrated amp or go separate?
The only integrated amps I can think of that matches the class of 804D would be a VAC Phi or upgraded Avatar.
Otherwise a highly modified Jolida JD502 might work.

Thanks, that's what I thought. I'm looking at the Bryston B100 SST or the Krell integrated.

CAV-50 may sound better than Krell integrated unless it's one of the newer Krell's made less than 10 years ago.

I had a similar issues (my sweet sounding crystal clear amp went all grainy and hard sounding) with a Audio Research CA50 and B&W 805s's. The bottom line is they just do not work well together. I ended up swicthing to a McIntosh 2275 and all was well. The CA50 is now happily driving a pair of AR S310HO's with Sequerra Ribbon Tweeters with no problems.

If you liked your tube sound but want to find a better match to the B&W's I would recommend the W4S STI 500. I have the ST500 on my N802's and it is excellent (and not just for the money).
