Cayin A - 88 T , sounds great but ...


I just acquired this integrated a couple of months ago , it is my first experience with a tube amp . I must say that I really do like this amp and what it has done for my listening pleasure . However , I am not into the involved biasing procedure that is required . There for , I am looking for an integrated tube amp that would be , at least , equal to the Cayin in sound production ability and be either self/auto biasing or extremely easy to bias without removing anything , including the amp from the stand .
I am using Reference 3a De Capo i speakers in a small room , near field . These speakers are rated at 92 db. sensitivity without any crossover and have a minimum power rating of 5 watts . I prefer to listen at low levels but do crank it sometimes . I listen to classic rock and contemporary blues . The new contendor should be detailed , extended and dynamic at low listening levels .
So far I have found the Prima Luna Prologue II (auto biasing) and the VAC Avitar (biased through a front panel without the use of a meter) . Of course there is quite a difference in price with these two . I do not have the ability to audition either one of these and am relying on what is in print .
I would also like to hear about other recommendations .

Listenhere ; Self or auto biasing is as the term implies . The amp contains a circuit that will bias the power tubes on its own , no user intervention required . The speakers , that I listed above , are quite nice and they are not fully broken in yet as I have only 135 hours on them . The dealer stated that the tweeters would require at least 200 hours to open up . The only caviet that I have is the 'somewhat' lack of sparkle on the top end as compared to their predessors , Soliloquy . This could also be a coloration aspect of the Soliloquy's .

Lindisfarne ; The Wright amps seem to be all SET's , do you thik that they will provide the extension and dynamics that I require for my music preference ? I can not find any listings here for Fi .

Rar1 ; I have read your review and it was a big factor in my decision to consider the Prologue II . Good review by the way !

Mrtennis ; Could you elaborate on the differences between the Almarro , Cayin and Prima Luna in relation to the extension , detail and dynamics at low volume , please ?

Thank you to all who have responded here ! Very helpful , as always !

Anyone else ?
Saki70, A couple of comments regarding small tube amps, especially the Primaluna models of which I have the One and the Three/Five combo.

Low volume dynamic's are far more likely to depend on your speakers that it is your amp when you're dealing with tube integrateds, although tube type choice can be influential. FWIW, in the PL5 which comes stock with KT88's, I have used every type that it can take (except for KT90's which have a signature I'm not particularily fond of). With my associated components I find the KT88 (SED's) to be somewhat fullish in the mid/upper bass, producing a warmish sound, with a slightly airy but uneven upper mids and highs. Actually a lovely, if somewhat non-linear sound. When using EL34's the deep bass takes a vacation (with small speakers no problem there). I found 6l6GC to be similar to the EL34's but they were a bit smoother thru the upper mids and highs - not overly warm though. Didn't leave them in long. Most recently, and surprisingly to me at least, I tried some SED 6550's. At first I just found them tonally too cool but after a while when playing some music with very well defined mids and highs I discovered what I didn't like about the other tubes! With the 6550's the upper frequencies were crystal clear and smooth. The bass was full and deep with out any upper bass bloom. All in all I think a very accurate tube in this amp with my stuff and it will be my tube of choice. BTW I still use the EH12AX7's that came with the unit - I found that they support the bass much better than other available new production tubes.

My point, in case you haven't figured it out by my wanderings, when you're considering tube amps its much more involved than just what brand of amp you buy but its the extent you are willing to go to get the sound you want out of your speakers.

My advise to you at this point of your experimentation, is to get the PL2 and a set of SED EL34's and a set of SED 6550's and then spend some time listening. If you don't like what you get you can sell it at minimal loss. If you do you can then fine tune it with different small tubes.

One last FWIW. In two non-PL amps I use KT88's in one, 6550's in the other, and using different small tubes I get a sound very similar to the PL5 w/6550's, the differences being in power, resolution, and subteranian bass capabilities.

I lied, one more FWIW - If absolute resolution and full bass that is less than tight is not a big deal for you, and you love a big, warm, linear sound, very smooth w/no rought edges, admit it and just buy the PL One. For less than analytical listening it is really a great little amp! Hell even Mr T might like this one. :-)
Newbee ; Thanks for the tube comparing on the PL's . I assume that your refernce to the PL5 would also apply to the PL2 . I was not aware that the PL2 would take the EL34's also , how about EL84's ?
I chose the De Capo's and the Cayin for their low level characteristics . I included that in my request so as not to loose that feature when switching amps . My previous amp was not as good at low levels as the Cayin .
Again , I am switching amps due to biasing procedures , not sound characteristics . The Cayin is really pretty good !
Saki70, So far as I know the Two will not take EL84's. Re comparisons between the Five and Two, the units are very similar in design with a few differences, one being the absence of negative feed back in the Five and I have been told that sonically they are similar. Rarl has both and can comment on the differences if any, however I don't believe he uses the Three. Obviously choice of pre-amp can affect the sound of the amp. If the only difference between the One and the Two is the speed, taughtness of the bass, and resolution, as well as the different tubes and their individual sounds, the Two would be an excellent unit. I haven't heard from anyone who has both the Two and the 3/5 combo. You might call Kevin Deal and discuss this with him. He obviously has total knowledge of these units.

Regarding low level performance, my listening levels usually average about 80 db +/- 3db, and I note no loss or improvement for that matter, with the PL amps with lower or higher volume.
