    • T-Audio (G. Trifirò, Messina, Italy) PrePhono Reference
    The tubes used in this project are a pair of 12AX7 or ECC83 NOS, as the first gain stage in MC, the second stage is made with the help of a pair of 6922 or ECC88 always NOS with the attached passive RIAA network connected at the pre-final stage of 12AT7 or ECC801S.
    Last stage in current but with hybrid technology operating in pure Class A is made with an excellent Triode of the Siemens CCA series, half per channel that drives a pure class A polarized stage of high current Mosfet, ensuring an output level sufficient to drive any preamp stage with an impedance value of approximately 10 Ohms per channel.
    All power supply stages with a solid-state electronic stabilization system differentiated for each single section and gain stage with an attached inductive capacitive load (in order to improve the signal-to-noise ratio and consequently the resolution in terms of timbre and dynamics).

You have put together a very nice system.  I like your approach.  Here in the U.S. where I live, Pass Labs is close to where I live, so I use their amp and preamp. But after several phono amps, I finally bought a tube phono, the Herron Audio.  It is great, and it can be configured a hundred different ways.  

I see you have done some room treatment.  Great that you are doing that.  I'm not familiar at all with the tools you used.  Are you satisfied?  Are you finished with treatment yet?   I am in the middle of treating my room 22' x 12' x 9'  So far, I've done extensive corner treatments, plus a combination of quadratic diffusion and absorption on the entire rear wall.  No side wall or front wall yet, and no ceiling treatment yet.  I haven't figured out exactly how I should treat those surfaces, so I'm waiting.

Hi Jo, I'm from Naples and I live near Turin!
After buying the Sa5000 in the USA (updated by M. Elliott) I had several problems with the power supply. While browsing the net I heard about Mr. Trifiro as a person who knew counterpoint products well and was in charge of some niche HIFi products. Contacted him, he maked right again the Sa5000 which is improved, losing only a little boost in the phono section (for this reason the MC is a medium output on the GN bellavista maggiore). The pre-phono, originally "AiFai" brand, has been improved compared to the original project. The DAC is his personal design and production, adapted to my aesthetic request.

That's quite an interesting looking system love all your tables. Never heard of T-Audio before you are obviously a fan are you based in Messina yourself? And Love the A-50v/Proac K6 combo it must sound phenomenal.
