MICROZOTL2 Tube Headphone Amp and preamp: a breakthrough device
Feb 10, 2016 at 1:17 PM Post #933 of 2,609
Looks like $300-$400 for a pair of tubes is what we're talking about, huh? Small price to pay for audio nirvana, I suppose, but I hesitate a bit having just spent $200 on 2 pairs that, so far, haven't done it for me. Seems it's a bit hit or miss in the tube business. (maybe I would have been better off going whole hog to begin with, who knows?)

You said it!  I'm certainly no tube expert but have dabbled quite a bit over the years and there seems to be even more of a range of contradictory opinions on the characteristics of various tubes than there are about headphones.  It can turn into a never ending project, but if you enjoy that kind of thing go for it.  In my own experience, the current tubes are very good.  I think a lot of the bad rap they have is based on the Chinese tubes of 20-30 years ago that were truly horrible.

I haven't compared the ZOTL tubes to anything other than the 2 sets of 6SN7s I recently got (NOS and all that), so far, RCA version better in some ways, not as good in others, went back to the stock tubes for now.

That's one reason to avoid tube amps... to avoid wasting money on tubes.  :)  You're not going to like the sound of every tube you buy.
 
If you shy away from the more spendy options, which is not a bad idea, then I think there are Sylvanias, GE, and Raytheons worthy of consideration.  I think several pages back theres a Sylvania recommendation.  The Mullards might be good too.  I'm not sure.

Why not save the money for tubes and buy a better power cord

Or, as they say in the commercial, "porque no los dos?"

Received my ZOTL & SBooster PSU yesterday. Today the Siemens E81CC (trimica) arrived and went directly into the amp. Will give it some time to burn in but for the moment I am really happy!

Can I ask where you ordered them? 
 
They're $175 each here:
http://www.nosvacuumtubes.net/product/siemens-e81cc-ecc801s/
 
But only $60 each here:
http://www.tubemonger.com/Siemens_Halske_1966_3_MICA_E81CC_Munich_ECC81_p/175.htm
 
 
I ordered some new Genalex Gold Lion 12AT7s because they were on Amazon and I had a gift certificate. I hope it wasn't wasted money....

Thanks...I actually had ordered from the same dealer as you did, but for more than you paid. I contacted them and changed to the $60 per tube at their site. :)
