The ultimate 6SN7
Tube rolling is an obsessive, compulsive madness that can drive you to the brink of insanity...or am I (you) already there? I love the lush tonal qualities of 6SN7 preamps. My current favorite is the ModWright LS100. My growing stock of 6SN7's from other preamps didn't fair that well in the LS100. Of those my favorite is the 1951 Sylvania BadBoy, with black plates and 3 rivet holes. But the bass somehow disappears in the LS100. Bass and dynamics with the stock EH tube and its gold pin variant are wonderful, but there's no air and space or any of that famous 6SN7 lushness of tone with these tubes in the LS100. I was about to give up when I tried the Black Treasures. Though really pricey (damn!), these are far and away the best tubes I've heard in the LS100, including the Sophia Electric. Like the EH tubes they play louder, are dynamic as hell, and have amazing bass impact and depth. But they also have that 6SN7 lushness, spaciousness and air in spades in the LS100. An amazing tube that you can listen to and get lost in the music for hours. This is what it's all about...at a price.
