@ charles1dad, Thanks for your response, Hey, Did you hear tube magic when you listened to the m-1?, I ask this because, I have had 6h30 tubes before, LOL!, sounded to much like solid state than tube magic compaired to the 12au7 and 12ax7 tubes!, I like a little tubey sound, If a tube componet is so nuetral, whats the since in having the tube componet?, I would do solid state then.
