I hope another forum post is O.K. See reply by Jan Vigne on Ecoustics message board: http://forum.ecoustics.com/bbs/messages/1/452675.html. He makes some real good points about tube amp specifications & reality.

99db should be OK with a 300B amp, and Yaqin makes a 300B SET amplifier that you might want to check out. I am driving my 88db Quad 12L2's with a 845 SET amp with no problem in a medium sized room. The Cayin is probably twice the price as the Yaqin, but you get advantage of being to able to hear it in person. Although I haven't heard anything bad about Yaqins.
Your link does not work for me.
I've checked out the Pacific Valve website. I am not sure I found the specific amplifier you were directing me to but I am very interested in the Ming Da MC 34AB 07. It seems to be a very good value as well.
I'd like to throw this model into the mix. I am curious as to the differences between a KT88 and EL34 output tube amp - more specifically these models but in general as well.
Thank you guys for the input so far. It is helpful to me and I appreciate it. I'm going to make a decision soon. Funds are pretty much in place for any of the three.
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.
