Butler Monad A100 vs newer options


Hi

There is a Butler Monad A100 for sale at the moment which I'm seriously considering making an offer on.

My question is, is this 10 year old amp / technology still relevant compared to more modern incarnations? Am I better to put my money into something like the BHK250?

I'd be replacing a 15 year old Perreaux 250P.

Cheers
