Russian 1587 tubes

Hi guys,

I have tried many different 6sn7 tubes even the Tungsol
round plate (known as the "Holy Grail" of tubes) but I
have now found the best - Russian Military 1587 -
These tubes are incredible the best of the best my system
now sounds so good everything is real and life even my
German shepeard thought that there was a fly buzzing around last night (me too for a few seconds) These tubes deliver everything, soundstage, presence, air, detail, warmth, life,
beautiful tight deep bass and the range is limitless -
I am using Cary 306 professional to DBX to Cary 300 SEI to
Tannoy 15" Berkleys with Tannoy ST-200 super tweeters.
Inter-connects are all Tyr balanced and Tyr Speaker biwired
speaker cables. Power cords are all Lessloss -
I hope that this is good info for all you tubies.
