EH Gold Pins are back in. Exactly what I expected - fuller sound, smoother, bit more presence in the bass, more romantic in the midrange. Sovteks are more lively, faster sounding tubes.
All comes down to what you and your system need. I would not say there is a loss of information with the EH Gold Pins. not at all. They're just a bit less analytical than the Sovteks.
If this is the sound you want, I think they're worth the extra few bucks they cost over the Sovteks.
