Although I had enjoyed fast and exciting sound out of Sr1a driven by Jot R for the last three months, I keep going back to 009s driven by Kgsshv Carbon amp from time to time to get more relaxed sound.
Especially violin has more beautiful tone through 009s.
To tame somewhat hot sound of Sr1a, I ordered and received Freya+ this morning
I skipped JJ stock tubes and inserted Nos Amperex 6sn7gtb in gain stage and Sylvania 6sn7gtb in buffer stage.
After running demagnetization tracks twice( 6min each) on Freya and Jot R, I started listening to Capricio Italian (Tchaikovsky) directed by Bernstein.
Wow, Freya with Jot R sounds much better than Jot R only with more relaxed and nuanced details but with minimal loss of transparency
Old Jazz recording by Benny Goodman sounds more relaxed with less hot edge from Freya and Jot R.
My digital source is Dave and HMS.
I still have several choice of tube rolling with Sylvania vt231, RCA gray glass 6sn7gt and all quad Syl 6sn7 gtb.
Encouraged by this result, I had tried Freya to Kgsshv Carbon amp to find its effect on sound of 009s.
Wow it make sound of 009s more graceful and natural with fuller bass.
Although I had been using only tube amplifier in my 2 channel system except driving subwoofer for last 20 years, I had chosen Carbon over BHSE since Carbon has a reputation of giving more fuller and deeper bass than BHSE.
But Freya + Kgsshv Carbon really make 009s sing.
T2 may be better than Freya + Kgsshv Carbon.
But I am not ready to shell out 10K$ on T2.
I will do more tube rolling on Freya to make it better match for 009s.
