One person claimed that using 300$ Melz 1578 at gain stage and 600$ TS bgrp at buffer stage in Freya+, he got the utmost sound out of it.
My Melz 1578 is staying in Line Magnetic 508, but I may try to duplicate his method.
It is best to rely on your ear after testing different combination yourself.
All I can say is most Nos 6sn7 tube made in 1950’ are pretty good and almost all Vt231ss made in 1940’s are excellent.
But King of 6sn7 is Melz 1578 one notch above all vt 231s including TS bgrp.
