Elrog 300B vs Takatsuki 300B tubes

Hi Calloway,
I 've been fortunate to hear many 300b s in my amplifier but the Pavane W.E. Replica wasn't one of them.I use their W.E. 101d in my line stage. I've heard their 845 often in my friend's(Jwm) Absolare Passion 845 amp. This is an excellent series of tubes from Pavane. It was the best 845 Jwm had used until he bought the Elrog 845(it's better we both agree). I'd expect that there's synergy using the same series of Pavane tubes. You're at a high level already with the Sophia Royal Princess 300b IMO. I wonder how much impact the 300b makes as a driver tube in your fabulous Chalice amplifier. I can't imagine you ever replacing that amplifier.
Charles,

Charles1dad...thanks for your thoughts..I do value them..I will probably flip a coin when the time comes later this month to order the 300b's. I will be having new interstage transformers installed next month in the amps...

Calloway,
New interstage transformers? My goodness, how much better can that Chalice sound?
Charles,

Wyan001, check out my thoughts between my J2 and Franks in this thread on 3-13-15.
I rolled a few different 6em7s. I didn't find any noticeable differences.
The rectifier and 300b make worthwhile improvements, IMHO.

Calloway I was using the WE845 tubes in my amps and they were the best I had heard. They beat RCA new old stock 845. When I switched to the Elrog's the difference was huge. I would not hesitate and get the elrogs especially with your great amp. The best Jeff
