I initially started out with the M15 then when the M25 became available switched to it and have been using it as my main amplifier for several years. I listen every day to it, basically it is never shut off.
Yes we are a Bricasti dealer but even if we were not it would be my amp of choice. Feel free to PM me or call, we are on Bricasti's website located 20 minutes from their factory in NH
