Found it, thanks for bringing that up

Thing is, tubes do not sound the same in differ amps and funny thing is, I just sold my pair of Sophias Mesh plated and kept KR's for now:)
Honestly, I dont know what to expect, but the good thing is, Sophias are not getting rare, they are in production and can be bought every moment I may want again, but I love rolling, but especially find the very best possible combo.
Anyway, their impressions about CARY 300 and Sophias are not complete to me, cos they dont mentioning any of 6SN7 been used. Thats what I came every time in almost every revieuw about 300B valves, they just drop pre amp section as not important one and I DONT AGREE on that one!
Good, first thing first, hopefully get my AVVT soon, will be back with impressions later, however if anyone can write some more info, please do!
