Favorite 300B: Sophia vs KR

Marcus,
True, but I did``nt want to be accused of 'over the top' praise. I was fairly confident you`d like them. With your Coincident Pure REF speakers I knew you`d hear all they`re capable of.I glad you took the chance and bought them.

Hello, all,

For those interested, I believe Sophia Electric is willing to let go of a few pairs of Royal Princess tubes over the next couple of days for $1000, shipped, a nice step down from $1200 shipped .

They have not posted this on their website, but people who are on an e-mail list are receiving this offer, good for only the next couple of days.

Just in case you needed some more ambiguity in which of the two tubes to purchase. Ha!

Regards,

Joe

My Ren 30 has the VAC branded 300bs so I'm pretty sure that I've got some untapped potential. From what I've read from VAC, I am concerned about the Sophia RPs in the Ren circuit. At $2K to retube, I've gotta be sure that they are not gonna go "poof" or worse yet, take out an OT if they fail. It really sucks that I only have a pair each of the KRs and the AVVTs (bought 'em when I have a Cary that used only a pair). Anyone got a pair or 2 of BTs they wanna swap?

Swampwalker,

I've got 4 used BT's that I'm going to try in my REN 30 this weekend. I've only had the stock Vac tubes in the amp since purchase. The Psvane 6sn7's were a great improvement in this amp so I'm curious how the BT's will sound with the Psvane's

"I am concerned about the Sophia RPs in the Ren circuit."

Swampwalker, that’s a very reasonable concern but I don’t think that you have to leave the results to chance. If you would like to try the RPs, I suggest putting Kevin Hayes in direct contact with Richard Wugang of Sophia to see if a tube set can be specked for your amp.
