Favorite 300B: Sophia vs KR

Charles1dad,

I honestly have been so taken with the Takatsuki/Frank pairing that I have not yet followed through on the Vac 30/30 pairing as of yet. The second set of Black Treasure tubes I purchased here on audiogon, purportedly from Grant Fidelity, are shorter and don't have the box markings that the ones I purchased with the Franks have so I'm a little afraid to pop them in without testing first. Unfortunately my tester doesn't do 300B's. I will find an avenue to get them tested before I try them out.
I'm currently breaking in the ASI livelines between amps and pre and the sound is just now starting to come around a little at 70 hours. Wasn't really impressed right out of the box but have the feeling they will be stellar after a few more hours
I'll keep you guys posted on the VAC/Black treasure pairing.
Markus

Thanks Markus, better safe than sorry.

I am currently using the sophia electric royal princess.
I have not heard another ,are they the best or is emission labs better for example ???
i do like the sound , very transparent and good overal dynamics / bass

I reread the thread, interesting , probably tatasuki but the SRP seems to be not much behind

Sorry misspelling takatsuki
