Musical Concepts Modifications

I've read nothing bad about his mods, ever.

I just had my Cayin 15 and Cayin 17 upgraded by a local tech guy here in BR. He changed the opamps on both with STUNNING results.
Highly recommended on that tweak. Cost me like 100 each player.

I had John do a $2500.00 mod for me and although i was satisfied, Iwish I had spent the money to purchase new equipment.

I have known John for over twenty years. His mods have always been worth the money. My first mod was to a cd player over 15 yrs ago. Way better. I presently
have his DAC with all black gate caps and other high grade parts. Excellent!!
As to what are the improvements in sound... it WILL BE BETTER...John
does a great job. Your best bet is to call him and tell him what your after.
He is able to mod specifically to your taste.
