Musical Concepts Modifications

I too have known John for over twenty years. I have done musical concept mods
and they were always worth the effort. I own his Musical Design products
and they are fantastic for the money. He uses parts that are better than any of the big boys. YOU can't go wrong with John.

Hi everyone. I just wanted to follow up and let you know how I made out with my modification. Well in short I could not be happier. The highend extension and transparency I was seeking have far exceeded my expectations. Sound stage? There is no longer a defined sounstage. My whole downstairs is the soundstage! All the things I liked about the GFA-5802 were maintained and all the annoying weaknesses are now gone. Oh, and no more Adcom "house" sound. The only negative I would mention is that it took over two months for the mods to break in. John said it has to do with the the black gates?. I started to get nervous after awhile as the sound kept fluctuating. But once it settled in, it was perfect. Now I can't help but wonder what he could do with my JVC DVD player. If anyone has anything they would like to share in this regard, it would be appreciated. Thank all of you for recommending John. I do not think I could have possibly done better for the money.

Yes9,
That's great news, glad you're happy.
I'm calling John and ask if he has any follow-up mods for my M-200's.
(They still sound fabulous after the mods of three years ago, just curious what he might have developed since hehehe)

Yes9,

Thank you for taking the time to post your follow-up story. I've never--ever--heard or read anything bad about John Hillig's mods at all. AND, he tells me that he owns Intuitive Design Summits!

Rx8man,
I'll bet those M-200's sound unbelievable. A dealer by me uses a pair of them to audition speakers and the only reason I didn't buy a pair is that they sounded so similar to the 5802. With John's mods, I can only imagine. By the way, this modified 5802 now sounds better than the BAT monos I auditioned. Way more lower end slam. Thanks again for the recommendation. Matt.......
