They are Cryo Telefunken ECC801s and E88CC very well matched and very low noise (800 $ for one set). Best! Nicola

Cryo RCA's? Are these cryogenically treated or have I confused it with something else? Seriously $600? That's a lot of money by anyone standards.

Tubes for my Raptor cost way less than that thankfully.

Wow $800 for a set of EMP tubes. I tip my hat off to you good sir as that is way more than what I would pay. As long as my EMP gave my fuzzy sound then I am happy.

So is the sound smooth fuzzy or sweet fuzzy? Or is it non-fuzzy?

I do not understand what do means the word "fuzzy", I just know that I have tested a lot of tubes like Valvo, Philips, Amperex... and the Telefunken cryogenically are the best open-detailed and toanlly equilibrated tubes I have found. The cryogenically tubes are only the best set, for a headphones amp is very important to have very well matched tubes, even the single central one (ECC801s), because these tubes are double triode and you need, even for a single tube, to have the two sections of the tube pefectly matched and very low noise... if you what the max (as I whant) you must pay a lot. Hard to find that kind of matched NOS tubes. Do a search to the Tube World or others like Upscaleaudio and you will see... With Telefunken tubes I find the most neutral and natural sound of my EarMax AE.

Best!

Picked up a quartet of nos RCAs for my 007tii. On one of the tubes, with the TVR4 trimmer maxed out, I can only get to a match difference of 0.175v. The other 3 tubes, I was able to match to 0v. Hmmm. Sounds great but should I return one of the tube? Not cheap. $240 for the quartet. Or is a difference of 175mv inconsequential?
