I thought I should I should keep only one nice head amp and this little guy won out of nostalgia more than SQ.
I also go through phases when i don't want to bother with tubes (warming up, shutting off, rolling, buying etc...)
The Joe Grado amp is dead neutral and need good upstream to please.
"Everything" sounds good on the MAD!
Oh wow, that's a beautiful piece of gear...Joe Grado is one heck of an interesting gent!
