@zipost I do not think TS bgrp is bad tube.But Sylvania vt231 also give spooky details and transparent window as well as TS bgrp but at one third cost.Law of diminishing return apply heavily in audio.I have pair of Telefuken 12AX7 tubes whose live... 
Shootout of Nos 6sn7 tubes
@ testpilot Two pairs of 1578 sounds clean without noise or hum and one pair give some high frequency noise before full 20 minutes warmup.Thus I am happy with my three pairs of 1578 made in 1980 and 1983.I agree with you that TS bgrp is overhyped....

If you want to experience 1578 tube, then I recommend this dealer who sent the tube very fast. https://www.ebay.com/itm/Matched-pair-Extremely-rare-1578-6N8S-audiophile-6H8S-6SN7-Metal-base/273874731266 It give some hum and noise at the start but ...

Nice thing of Line Magnetic 508 is that you can fine tune its sound through tube rolling.Using pair of 805, 300B, 6sn7 and one 6sl7 tube, it is a dream amp for tube roller.I had spent more money on tubes than amp.Recently I had done shootout of 6s...

I am back to RCA vt231 in Line Magnetic 508 amp which make me comfortable with lush and warm sound but also with nice bass. f I want explosive bass or widest and deepest soundstage, I play 1578 Melz.Ken rad vt 231 has nice bass with more air than ...

I had used Rogue Cronus Magnum ii for 6 years and then switched to Line Magnetic 508 about 2 years ago.LM 508 SET give lot of meat and more bass control and too much fun with tube rolling.But it will drive your speaker pretty well. https://forums...
