one of the US KR reps has these listed around $1500, does that sound right?  Ouch. :)

Are those different from the KR 300b HP tubes? Or has anyone here tried the KR 300b HP?

Don't know. Someone will be along shortly to elucidate.

Until then, what sayeth the hive on these?  Never heard of them. Are they 2a3?

Anyone interested in a pair of 300b tubes that cost more than a new L2iSE? :peek:

I saw them on Amazon.  The Lampizator and Border Patrol experts feel they sound good when they're good, but they are bad when they are bad, ie extremely variable.

I emailed with Partsconnexion on Friday and they said they will be getting more TAK TA-300B's in mid next week. Been driving myself crazy with curiosity about the Japanese tubes after reading everything here in AC and elsewhere on the web. I guess that would be a colossal jump from stock 2A3's to the TAK's

FWIW, I have the Taks and Elrogs, the tube that gets the most play in my Lio DHT are the 2A3s Vinnie sends with the DHT.  Very speaker dependent, I am running GR Research NX Oticas MTMs over Servo Subs in H frame alignment, YMMV.  Clarity of the 2A3s is what impacts my impressions.

Best,
Ed

BTW, in my Bottlehead Kaiju, the Taks and Elrogs are my favorites, in that order.

2a3s are just a lower distortion, higher clarity tube than the 300b.  Not that I don't love the 300b, because I do.  But the 2a3 is about as close to "perfect transparency" as I've heard, outside of a Type 45 tube.  YMMV.

I'be been using them for about a year.  Better than the EH tubes - more extended, with a better defined midrange.  I can't compare them to the Taks or Elrods, I haven't gone that route yet, although I'm thinking about it.
