PRIMA LUNA AMPLIFIERS

Hi 

I,m thinking of buying a Prima Luna amplifier but worried re reliability, and what you do in the UK if you have problems.

Would like to hear what owners think about reliability, tube changes , tube upgrades, potential problems,
And what happened if you had problems re after sales repair and support.



i,m going to use them with Proac D20 r floorstanders .

 Thanks in advance for your help

I recently purchased a used Evo 400 and am extremely satisfied. I have been a audiophool since the seventies and have had countless amps.  I can't see ever giving up this amp.  I have replaced the stock el34's with kt77's and also the two main 12au7's with some nos radiotechnique .  Just a heavenly sound.  I also agree with other posters that this thing is built like a tank.

I recently purchased an evo 400 integrated and am currently running it with the stock el34 tubes (happily I might add). I am about to purchase a pair of the Focal Sopra 2s and am considering rolling to the KT150s. 
Question: With the uptick in tube size, can the Evo’s cage still be closed with 8 x KT150s in there?

I think I read somewhere that the cage won't close with KT150s, but I cannot confirm this.

Slightly off topic, but how does the EVO 400 work as a daily driver? How fine are the volume adjustments via remote?

This review with KT150s of the Dialogue Premium says the cage cannot be closed using KT150s.

ksubrama:

The 150 draws considerably more heater current than the EL34. Can the amp supply it?
The operating point will change which will change the distortion considerably.
Do you have the tools / know how to adjust the amplifier to optimize for 150's?

Just WHAT do you expect to achieve other than a thinner wallet?
