Thx,
Spatial Triodes are better in every way then the Gallo 3.5, except teeeter.
The tweeter preference is close call !!
For my price of $2500 it is a no brainer.
The M1s Triodes are so smooth and the best imaging I have ever heard even better than Gallo.
Not easy to do. Plus Gallo no longer makes the 3.5, if ever a problem, can’t get parts.
