Thurston, the Teles from Upscale ARE IMHO the best Euro tubes available. Keep in mind I like detailed but smooth sound, not really an Amperex type guy. I still have my Platinum set. And even though some of us have had issues with Upscale and Kevin's attitude and alleged superior "grading"(myself included), his Teles are the real deal, NIB/NOS. Nobody has better Teles for anywhere close to his price. As regards the 6N1P's it is all about vintage and interior construction. As RB2013 has succinctly pointed out in his evaluation of the 6N23P genre, the "single wire post getter" units VS the double post getter makes a BIG difference in the sound, and the price he charges. His top of the line 75 Reflektor HG's,SWPG, (Holy Grails), go for close to 100X his price for the generic double post units. Keep in mind the generic units are still an awesome upgrade from the stock tubes. I got interested in the 6N1P's reading the post's by jamato8 in the first Lyr rolling thread. Russian tubes have an extremely variable "sound" quality based on vintage and "grade". Without spending anymore time reiterating what is available there, my 75Rocket,SWPG, super matched, gold grid, 6N1P's sound awesome. Jamato8 in his eval preferred the 60s vintage as they were made for analog vs digital, and sounded better to him. My 75s sound awesome, can't wait for my 66s. BTW, the 6N1P's require more current than the 6DJ8, and only the Lyr-1 meets this spec. Concurrently my modded T50s like a lot of current, that the 6N1P's provide, just some insight, satwilson
Steve, If you can hands on ANY Voskhod 6n23p...I mean 76,77,78,79....Also 71 abd 74 SWGP...These tubes really have great sound, it's worth tube rolling. I really suggest get those tubes..
