Need Tubes


My Audio Research LS25 MK2 is in need of tubes. I was going to order a set from Audio Research but wanted to hear from you guys who may know of a better tube.

Years of buying mostly (6550C and KT88) Sovtek, EH, etc etc my favorite is JJ. Great price, great sound, great reliability. 

Always bought from tubestore.com but the worst sounding and least reliable (2 out of 5 blown inside 2 months!) were their Tubestore brand name tubes. They replaced them under warranty but when it gets to the point you are worried to have your amp on unless you are there to keep an eye on it.... never again.
for arc ls25 mk 2 .... it runs russian 6h30p’s only, can’t roll tubes

mk 1 was still 6dj8/6922, this was the model changeover to the russian 'supertube' or so they called it

just buy from arc if cost is not a factor

or order from jim mcshane, upscale audio or thetubestore in canada to save some $, all these excellent tube vendors properly test tubes themselves before shipping, you will get good ones
Brent Jesse has an excellent reputation, I certainly have had great experiences and saved money.

I tried some Sylvania’s, didn’t like their sound. They had me break them in 60 hours (simply on, no source needed), listen, still not happy, returned, got less costly GE’s, love their sound, got a full refund for the cost difference, no restocking fee, I just paid for mailing.
