Preamp Deal of the Century

One of the reasons the Supratek sounds good is that it uses a tube based shunt regulator, which is pretty rare. Most manufacturers go for a much more easily easily implemented series regulator.

I have found this tends to give a very solid and assured sonic signature.

There’s a “Reference 6SN7” thread on head-fi and a “Shootout of Nos 6sn7 tubes” here on Agon. Another with the same title on What’s Best Forum. Then there are tube dealer charts, as mentioned above.

I have several older 6SN7 and 6F8G pairs available to try out.
