| The NTK is pretty harsh. Or maybe "silibent" or "strident" would be a kinder way of putting it. It can capture a lot of detail, but some sources are painful with the NTK.
Replacement tubes can be worthwhile, though not the magic bullet some make them out to be. 6922, 6N11, 6DJ8, and EC88 are all replacements for the stock tube. I've got a EC88 in mine right now--it's branded RCA and marked "Made in Holland." It's a little less harsh, but has less gain and possibly more noise. |
