Been comparing the amperex USN CEP from mercedesman with my e188cc white lable PQ tonight out of curiosity since I've seen a lot of talk about them lately. They are both extremely fine tubes for sure (only have been listening with the LCD-2 so far since this is the closest within my reach now as I'm breakin them in).....I do feel that the e188cc will throw up a bigger soundstage and offers a bit more detail compared to the USN CEP's. But definitely the USN CEP's have been hitting the right notes in terms of bass....that's probably the first thing I noticed putting these tubes in. Pretty satisfied with the USN CEPs, ordered the white label amperex hewlett pacard with the D getter from mercedesman as I saw him throw up another NOS pair that measures very well. So far I'd have to say my top tubes are the top Amperex white label tubes and the Lorenz tubes made in Stuggart (mica-2/mica-3). The Mullards are nice and smooth (cv2492/cv2493/blackburn etc) but cannot compare to the overall clarity and dimensionality of the fore mentioned tubes.....
I dunno how some of you guys could completely give up the Lyr to go SS (I have both the Mjolnir and the Lyr).....although the Mjolnir sounds uber nice with harder to drive headphones and is just damn clean through and out.....I find myself still going to the Lyr a lot of the days since the tube sound is something SS will never replace. Especially after a long day @ work, I need that warm tube sound therapy to relax me.
