I am a fan of Herron audio for a few reasons. Keith's products sound excellent, are well built, can be upgraded for a nominal fee and Keith is just a great guy to work with. I have upgrade my original M150 amps to the M1A. Is there better equipment out there?....I'm sure there is but I have quit chasing the promise of better sound and instead just listen to music. I have had good success with using roller block juniors under the VTSP-3r02 pre amp and will probably go that route with the amps.
