Audio Aero Prima integrated Mk1. Just bought it

Hi everyone, while I am waiting for my MKI to arrive I emailed the Audio Aero guys because I was wondering whether this is a class-A amp or not. Well, they finally replied (to my surprise) saying this is a class-B. (Not even a class AB.) Well, I know there is more to life than class-A and other technical specifications, but can anyone provide some thoughts on this matter? Thanks, Josep

I just purchased this MK I version and it is very good. The used market makes these a steal. I have not heard everything but it is the best that I have heard. It bests
equipment that goes for twice or more of the new price. I was worried about it being only 40 watts but it has more power than I need and I listen to a lot of rock. It will also kick out enough base for rock music, something that some integrateds won't do.
Thank you Boa2.

I just received the MK1. I must say I am really impressed with its performance. The sound is warm and honestly I don't know why you need more than 40W. It makes my Triangles fly! The only thing that surprised me is that it did not have phono stage, but that's fine. I don't even own a turntable. Right now it has the Tesla tube in it and I bought a couple of Mullards and the Siemmens to compare, but I think I'll wait, since it seems that it is pretty tough to open. (It's got many screws...)
In addition, I have to tell you that Audio Aero contacted me again correcting their last email. The amp is AB, apparently it uses the TDA7294 DMOS amp. I guess that just gives me piece of mind. Thank you all for your great advice. Josep

Josep,
Get yourself a number 2 allen key and take the 7 screws out of the case. Remove the cover by sliding it back a little. Carefully remove the tube so that it does not rock the circuit board to which the socket is attached. Then change that Tesla tube. You will notice a welcome improvement with either of your replacement tubes. Try them both to see which you prefer. Also, that amp doesn't really warm up for about 25 minutes, which you may have already noticed. Enjoy!

Hi, quick question, I am trying ot use the Prima as a preamp. Has anyone try it with McIntosh or Gamut? Can you tell me how to hook it up?

Thanks,

Josep
