Favorite 300B: Sophia vs KR

Isochronism,
Abill is referring to Gsm`s Takasuki 300b which are`nt compatibile with his Ancient Audio amp. He`s not referring to your RP tubes sent to me.

Thank you Charles. I have to remind myself to stop and take a breath after running in the door, before I sit down and try to think.

Thanks for the effort in trying. I am sure your tubes are sold but if not email gwalters@charterwest.com. I will own both Takasuki one of these days along with my RPs. I own the Border Patrol S10 EXD with fixed bias so tube biasing is not a problem. In the mean time I will await for more drama to unfold.

While awaiting the main event results some might be interested in my
findings with the "lesser" Psvanes and AVVT 32b. Right out of the box the
Psvane 300b-t sounds a little more detailed than the BT's while retaining
very similar warmth and magical midrange. Overall I think it is a better tube
and only 15 hours on them. The AVVT's were shockingly lively, detailed
and very neutral. Not quite the lusciousness of the Psvanes. Probably will
be my go to for classic rock or shorter listening sessions. Can't wait for
these tubes to reach 200-300 hours. BTW, I will probably list the BT's with
700-800 hours on them. Also for those with the Coincident linestage, I
have 2 pairs of 101D's that I no longer need

Gsm, I would much like to see your tubes go to Charles, either as purchase or loan for the comparison between the three.
