Elrog 300B vs Takatsuki 300B tubes

Ddriverman,
The issue of compatibility of the Elrog with various 300b amplifiers has been raised on this thread. Given that you have two different 300b Amps it will be very interesting to see how these tubes perform in two different amplifier circuits.

Bill(Brownsfan),
I received an interesting email today from audiogon member Mark who recently got a pair of the Elrog ER 300b tubes. He loaned these tubes to Israel Blume to try in his system. They both feel that these tubes were just a subtle improvement and did not justify their high cost. Israel, Mark and I agree upon the substantial improvement rendered by the Pavane W.E. replica 101D tubes in the Coincident line stage. I find the Elrog just as impactful (at the very least) so while I obviously respect their impression, I will respectfully disagree. As more people listen to the Elrogs it will be interesting to note their impact according to various listeners. Israel does not find the Elrog 300b upgrade that he does the Replica 101D in his components. For me, both were major and welcome additions in my system.

Interesting Charles, and thanks for the info. Any idea what 300b the Elrog was a "slight improvement" over in those systems?

Cal,
For Israel I'm pretty certain it would be the Pavane Black glass version. I Often agree with Israel in most cases regarding the sound of different items and components, but not in this case. The truth is that some will share his view that the improvement is only subtle, and some will share my view that the Elrog is a significant upgrade.

Charles,
I suspect that the difference in ancillary equipment, DAC, various supporting tubes, wires, room and so forth account for the different point of view...as is usually the case, but I know you know that. At any rate I'm looking forward to hearing the Elrog.
