Musical Concepts amplifier modifications upgrades


I would like to hear from people that have had their amplifiers modified by Musical Concepts. I am looking at having two GFA- 555 amplifiers modified / upgraded by them. I only want to hear from people that have had their amps. upgraded by Musical Concepts.

John (Hillig) is a great tech and a really good guy.  I've known him for many years.  He did a couple of Hafler and B&K amp upgrades for me back in the day.

Wonderful work and well worth the money back then.  Not sure what the charge is now for your amps, but there are many decent amps now on the market that may be better than putting more money into what you have?  Just sayin'.

If you do have John do the mods/upgrades, you won't be disappointed.
@tomcheeser...I saw your other thread about Big Sky Audio.  I've never heard of those guys.

If you really are going to have this done, please let John do it.  He's been doing these mods forever and probably knows more about them than anyone, (just my .02 cents worth).
