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 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?

Thank you @shahram. I don’t think it will fit with the cage on the evo 400 as well.

@ieales  - appreciate the challenge. Being a Tube Newb, I absolutely do not have the tools or knowledge. However, I purchased the PL evo 400 for its auto bias design and the marketing slogan on it being so easy to use that even a tube newb would be able to roll tubes easily. My only intent is to get more power to my speakers and get increased dynamics/bass response from them.

@ shahram - missed answering your question:

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

It is working great so far. Much more heat compared to SS, but I leave it on about 4-5 hours at a stretch, give at least 30 minutes between power cycles, and avoid rapid power cycles. Takes a minute to warm up and tubes are fully charged in 5 mins or so. I will admit that I feel nervous when the PL is on with no music playing, almost feel a compelling urge to turn it off.

As far as the remote goes, it is superb. No power on/off obviously but the analog volume control is very responsive. No steps as such but a single press on the remote gets you 1-2 degree turn on the volume dial. Very slick and responsive.

Sharing a recent post from the PL Steve Hoffman Forums with some very cool pics of the PL Evo 400 with the KT 150s, as well as an innovative solution for the cage. See page 8. Thanks to @zurv
