I ended up happily with the Cayin A88T after swapping out a dozen or more amps solid state and tube. The Cayin may be your last amp also. It bettered for my tastes everything else. The Conrad Johnson was too smooth almost dull to me, the Cary, a little too detailed and clinical. The Cayin has a vibrant front row center real performance sound to it. It is one of the best amps out there in my opinion, at any price.
My suggested tube complement is SED KT88, Mullard CV-569 or ECC35s (european 6SL7s, these will cost but are well worth it) and RCA VT-231 (military 6SN7). If the amps seems slightly too open to you, adjust the bias from 400 to 340.
