Belles research?

Phusis - Thanks for the link, very much appreciated.

Got my SA-30 this week, at this moment listening to Idle Moments ( Grant Green )
Sounds wonderful and I am using the pre out on my old solid state intergraded amp! Very happy also that it is sounding great on low volume.
Looking forward getting a Supratek pre to give the Belles some quality.
The amp oases quality, but it does get quite warm, so good ventilation is paramount.
Very happy with it so far.

SWEET!  Wonderful amplifier.  All Class A amps run very hot.  IMHO, the hotter it runs, the better it will sound.

Mick makes a GREAT preamp.  Should mate very well with the SA-30.

You picked some very, very nice gear...

Thanks, hopefully I will get the Supratek later this year, I don’t change system often, the one I have is from early 2000, newest addition the Primare Dac 30 that I think came out in 2013!
After the Supratek I plan to get a better dac, maybe a Audio Mirror  Tubadour III SE.
Using mostly Roon now, so maybe a dedicated server will be on the cards later, but for now the Mac Mini is doing fine.
The plan was to go intergrated, but I have come to realize that I want tubes somewhere in my setup and the pre looks most logical place to have them.
Maybe when I am a pensioner I can look for that intergrated Class D amp ;-)
