The Amperex tubes (yes even the famed pinch waists) have one weakness.
Compared with other tubes, their soundstage is slightly smaller though I wouldn't label them as constrictive.
Lorenz Stuttgart PCC88s have one of the best , if not the best, soundstage.
After replacing my Lorenz PCC88s with the pinched waist, I still kinda missed the immense soundstage.
Enter the E288CC!.....
This is a bizarre tube in that it is technically not the same as the 6DJ8.
It is taller and although has the same tube pinouts, it has 2x the gain.
What I like about the E288CC is that it seems to create a very large soundstage without any sonic veil like a Siemens CCA but with mids from an Amperex.
This tube does everthing well and is one of my fav tubes.
Just need to turn down the volume a little.
On an Amazon customer review of the Schiit Lyr, someone also praised the E288CC highly.
I have a lot of differently labelled E288CCs, they appear to have been made by Siemens despite being labelled as Telefunken, Valvo, Philps... Etc.
The "correct" vintage of E288CC should have internals like the one in the following link
The newer " A frame " version currently sold by Upscale Audio does not sound as good.
