Last week I have received my new balanced Supra with most upgrades, I believe pretty close to an SDS.
So in the last couple of weeks I have analysed the different threads about tube rolling on SinglePower amps, including the fantastic job made by Adhoc (a real asset for the headfi community) and the excellent tube rolling thread started by Hirsch about 6SN7s.
I have also seen several thread regarding tubes for the MPX that were not formerly available for the Supra, but those threads were quite sporadic and never managed to go very far, as if there was a wall between MPX owners on one side and Supra and SDS on the other.
Since my Supra (and I believe this is the standard for all SP amps) also accepts 6bl7GT, 6BL7GTA, 6Bx7, 6BX7GT and now SP provides adaptors to use
7N7, 7af7 and 5687 (please somebody correct me if I have got a letter wrong or if I have forgotten other kinds of tubes) I come up with the idea of finally reunite all SDS, Supra and MPX owners (and to some extent PPX3) in order for all to share experiences about tubes that can now be used in all of those great amps.
Of course, I discussed it with Singlepower East, AKA Earl, AKA SACDlover and he said he liked the idea and would be available for it.
The starting point of compairison might be the different 6SN6 experiences, where most people were suggesting Tung Sol round plate, Sylvania W, Sylvania VT231 1952 or Ken Rad as the best tubes and maybe compare them with the other formats now available.
The aim of this thread is to keep the ball rolling with new SinglePower tube experiences and to share them between SDS, Supra and MPX owners.
Let's get going
