Interesting stuff. Curious how the sorbothane can muck up the sound? I have a set of Pangea pico feet, but am not using them at the moment, but was thinking about putting them under my Lyr 3.Herbie's Big Baby Booties would be perfect under the Lyr 3 to help combat microphonics. A little pricey for some footers, but you can muck up the sound pretty easily with something like sorbothane (Gaaaaa…) or the peel'n'stick ones from the $0.99 12-piece card at Wal Mart.

I don't need the microphonic isolation, and prefer a non-compliant footer myself. The ones below work great, and believe it or not bring about a quite audible improvement over the plywood/foam feet I was using. If you buy anything like this on Ebay though be careful -- some of the cheaper offerings have a layer of carbon fiber on top and bottom and just a piece of plastic in between. I've bought several times from this seller (GD Parts) and have always received a true layered carbon fiber puck (you can see the 20 or so layers if you look very closely at the Ebay enlarged pic).

I consulted my "Healing Crystals for Audiophooles" handbook and Sorbothane isn't in there. Clearly not good.

Just out of curiousity, could someone here familar with electrical engineering explain why similar tubes (e.g. Sylvania 6SN7 vs. Ken-Rad 6SN7) sound different (in particular, differencs in, say, bass or midrange)?

Could be many things....
Cathode impurities could vary from one tube maker to the next, also the spacing between the cathode, grid and plate, grid material, maybe plate material and impurities? Also how the heater wiring is made, some might draw slightly more or less current thus boiling off more or less electrons from the cathode. Plate structure may play a part in relation to crosstalk or interference from one triode to the other.
All we know for sure is that G.E got all of the above wrong when making tubes.
That's the magic of tubes

Another question: has anyone tried an ECC32 lately? How did that turn out?

I saw earlier in the thread someone used ECC32, top tier tube i believe, only problem is it draws 50% more heater current than a 6SN7 so might fry a transformer with prolonged use.
ECC33 is a safer bet.
Anyone curious, as to whether the black glass/black base Brimar, sound the same as the black glass/brown base Brimar, well I am happy to confirm, that they sound the same. This was not much of a surprise, seeing as they have identical construction, on the inside. Funny how, my research online suggested otherwise, but that just goes to show, how much bad info, is out there. The clear glass Brimar, don't have the 2 little metal (coolers) tabs, mounted to the top of the grid post, but other than that they look the same inside as both black glass Brimar. Anyway, back to the music. I have a Gumby, on the way, Brimar tubes in both my Lyr 3 and LP, so I am getting ready to hear them, at their full potential.
Happy Easter!

Anyone looking for spooky realistic tonality and soundstage for days. . .Roll in a Brimar black glass. Now that I have my Gumby in the chain, I am hearing it all, and man o man, is the Brimar black glass, a killer tube!
Curious to know where you bought this?
From the Classifieds on this forum, and from an awesome forum member.
Anyone looking for some Brimar 6SN7GT, this is the seller and forum member, that I bought mine from. I highly recommend this seller, and can not say enough good things about him! Also, you can't beat his prices.

Before getting the Lyr3 I was a little worried that rolling the tubes would have little effect. I had also read just that in various places, that in hybrid amps, generally, tube rolling would just have a small effect (I don’t remember exactly where though).
After some (albeit limited) tube rolling on the Lyr3, I can say, that to my ears at least, the difference between tubes in the Lyr3 can be spanking HUGE. No A/B switching needed, not by a long shot.
That makes me wonder what it is that makes one tube sound different from another..? What makes a tube mid-centric, what makes it have a large sound stage, what makes it full of PRaT and dynamics?
Oh, the questions in life..
And now, back to some tubular listening..

If we only knew, the answers to those questions! One thing, as far as construction, I have often found that tall bottle tubes, sound different and most cases better, than short bottle tubes. I don't know, if there is anything to the bottle size, but my two favorite tubes, the "Bad Boy", and Brimar are my tallest tubes. I have read that tube rolling has little to no affect on hybrids, time and time again, and those people don't have a clue. First off, not all hybrids are the same, and the two hybrids I own, change a quite a bit, with each tube roll, as tafens just mentioned.Before getting the Lyr3 I was a little worried that rolling the tubes would have little effect.
