RE: Atma-sphere Mp-3 Phono Tubes
Posted by RedM on July 15, 2017 at 10:46:29:
They sound very good, much better than the bulk of at7 NOS. My favorites in my MP3 are Valvo 6201 in the first 4 positions and Siemens ecc81 in the last 2 positions. The psvanes are similar to the Valvo's with just a touch less body in the mids. They are more quiet than either of the other tubes. Used them for about a year without any issues.
