Which Primaluna amp ?

The autobias feature is very nice indeed. I will say I prefer my Dialogue 2 with EL 34s instead of KT88s.

I recommend you choose the most powerful in the series if you are going to buy Primaluna. The autobias feature is great. I also have Proac Response 2.5 and I think you will be happier selecting the model with the most power.

Skip the PrimaLuna and go for Mystere.

Wescoman,

Have you heard any of the PrimaLunas? Will you speak to the primary differences between them?

I've owned PrimaLuna equipment before. I bought the PL Prologue Three preamp and used it for six months before trading up to the Mystere ca11 preamp. The PL preamp incorporates an ultra-linear design configuration while the Mystere uses a push-pull design configuration with 6SN7/5AR4 tubes. For me, the Mystere was a better fit given my other equipment. I kept having issues with the PL not playing nice with other equipment. When I powered up the Mystere, all those conflicts went away. I continue to use the same equipment today which includes CODA solid-state amplifier, Manley phono stage, Rega Planar 25 turntable (Dynavector 10X5 cartridge), and Totem Sttaf speakers. If you have an opportunity to listen to both amplifiers - PrimaLuna and Mystere,I would satisfy that curiosity, because in my experience, the high-end division of the same company didn't cost me any more but the outcome was night and day. Hope that helps!

My listening room is almost the same dimensions as your and I have the Prologue 6. My speakers are 92DB and I've never been more contented with an amp, however, I would get the 7 since it's newer. You can change tubes to fit your mood with these amps.
