Musical Concepts Modifications

Hello everyone. I posted a couple of weeks ago regarding upgrading an Adcom GFA 5802 amp. Amongst the fine suggestions I recieved was one from JB recommending that I explore the modification option. Since I am 92% happy with my systems' sound and don't want to go through the whole rebuilding phase again, I thought this made sense. I'm really just looking for a little more high-end extension/resolutuion and a little more transparency wouldn't hurt. I contacted John Hillig @ Musical Concepts and he thinks his Lx Sig Mod would do the trick. I'm just a little nervous about investing in something w/out hearing it first. Ironically, I listen to mostly prog rock and am also worried that the sound may be TOO refined for my taste. I'm wondering if any of you have gone this route, specifically with the 5802? Any info you can provide is greatly appreciated. Thanks, Matt......

I had a pair of B&K M-200's modded by John, he's great with amps, no regrets at all.
They sound as good as it gets, warm, liquid, detailed and natural.

I've had several amps and preamps, (Hafler, Adcom, B&K) modded by John over the years. He and his work are WONDERFUL! Well worth the cost...

I have over the years owned numerous Musical Concepts and Musical Design products. I am more than satisfied with their components. I currently have an Adcom 5500 modded by John, a Musical Design D-150B amp, a D-140i amp, and (3) Musical Design CD players. They also are very good with any problems that arise. But what I like most about Musical Design is that you can always upgrade as finances allow. I am currently boxing up two of the CD players for updates. I would send all three but, I need something to listen to until the modifications are done. Jim

John's a great guy with a fine ear! I've known him and his mods for twenty years or more and he has always produced first rate product and he stands behind them 100%. You can't go wrong with John's mods. If you ever get a chance stop by and see his place, the sound is awesome and John's quite a character.

Just another endorsement. His cables aren't bad either.
