Elrog 300b vs we300b

Haven't heard Elrogs, but I can definitely vouch for the new WE 300B's - they took my Eddie Current Studio B to a whole new level, and they can now even drive my Susvara headphones quite respectably (they were not able to with JJ or Gold Lion 300B's). I do not regret that $$$ outlay one bit.... 

The Psvane and Linlai WE clones aren't  their top of line tubes, wouldn't expect they'd compete with the real WE.

I do not doubt for a moment that the W.E. is the much better sound quality tube. Curious as to how it has better ability to drive a load versus other 300bs.

@charles1dad I can only tell you I've not seen a single instance of premature failure of WE, only other tube meets this threshold is EML XLS. This through years of research of nearly all forums on interweb. I worry about durability of every other 300B tube.

Have you spoken with Israel about possibility of lowering heater voltage in your Frankensteins? I'm lowering heater voltage on my Statement since having some 101D failures, per Israel's recommendation, doing the install of two required resistors today. Lowering heater voltage may increase 300B tube life, some of these 300B amps run heater voltages spec'd to original WE300B tube, likely the most rugged 300B tube ever produced, seems many newer 300B tubes can't handle it.

I was not questioning the reliability of the re-issue Western Electric 300b, I’v not read/heard of problems. I was just wondering how this specific 300b has more ability to drive Susvara headphones (per larsman) more successfully than another 300b. What would be responsible for this to occur?

I have not spoken with Israel Blume about lowering tube heater voltage. I do suspect it runs relatively high in his Frankenstein 300b SET amplifier. I think this amp nay push the 300b harder than some other 300b amplifiers. I did not consider it may possibly be true with regard to the Coincident Statement line stage. I will say I’ve gotten pretty long tube life with the 101D tubes in this line stage. About 6 or 7 years using the Psvane W.E.Replica fairly heavily.

If lessening the heater voltage does not affect the superb sound quality of either Coincident component, then it seems a good move. The EML mesh plate I had failed very early in the Frankenstein (Amp’s rated heat dissipation too high for the more delicate genuine mesh filament). No issue whatsoever with the solid plate EML XLS (Exceptionally rugged 300b).
