Confused addict: need help with upgrade

Current sys: B&W Nautilius 805; rotel 1070 cdp; classe 151 integrated amp; audioquest slate and audioquest coral

I recently replaced my rotel 1060 integrated amp with the cap 151. I was pretty happy with the rotel but reading the magazines made me want to buy the next better amp. Different dealers said the Classe and B&Ws are "a match in heaven". I thought it made some sense because B&W distributes Classe. I auditioned the Classe at the dealer and liked it and bought it. ( I heard Krell 300iL may be too bright and CLasse has a more airy treble.)

While there is significant improvement in the base response, I notice more roll off at the high frequencies. The dynamics are vastly improved but I can't detect any significant difference in transparency.

(To avoid decompensating my neurotic-pyschotic neighbour, I listen at a reduced level with the Classe. The relative dynamic compression of the rotel is a mixed blessing.)

Is this an inherent compromise for an airy treble?
What should I do to increase the transparency?

I coninue to read What HiFi, Stereophile, Absolute Sound, HiFi Choice. I am thinking Sony SCD XA-777ES is the solution. Am I on the right track?

My dealer said the Signature 805s are much better than the regular 805s. Would my money be better spent with new speakers?

Any help is appreiated.

I suspect you're maxing out the front end of your system. Classe is indeed a good match for B&W. It is sufficiently powerful with enough current output and bass control. It also has a polite sound as opposed to some amps (you mention Krell in this vein) which can sound overly bright on B&W's.

It follows that you would hear improved dynamics - but I think in order to improve transparency you should audition some other CD players. The Rotel is strong at that price point but consider listening to something a step up. You might be surprised how much of a bottleneck the front end can be.

Also FYI leave your Classe and CDP on at all times - that makes a huge difference. If you aren't doing that presently you may find that will increase transparency.
