no synergy

I looked through the forums and didn't find an answer. I bought a Musical Fidelity A5 amp to power my B&W Nautilus 805's and find the highs are lacking. Ditto with the Wilson Witts I was using. I used to have a Pass Labs X250 amp with a Classe DR-5 preamp that was marvelous with the Witts. But the wife didn't like the size, so I downsized and have not been happy since. System now is the Musical Fidelity A5, B&W 805's with a B&W ASW600 sub. Linn LP-12, Jolida JD100 cdp.

I'm hoping someone could suggest another SS integrated amp with MM phono and excellent top end sonics under $2K used. I know the A5 is no Pass/Classe contender. May have to go back to separates.

I thank you in advance.
