your experience with mod or upgrade companies.....

I own the Oppo 105 that was upgraded by John Tucker of Exemplar Audio and the upgrade is simply stunning. Highly recommended.

The Upgrade Company goes after the radio frequency & electromagnetic radiation issue. They are very secretive about what they are doing to tackle the issue. There is really no reason for all of the secrecy.

OP-

over the years, several modders have left the scene. This is a sad fact, as we need modders. Theses guys had the talent and know-how to make gear better after the manufacturers cut corners, used lesser parts in order to make a profit. To my knowledge, the stalwarts like ARC and C-J, still provide excellent upgrade service. Mod-Wright is one of the few "indie" operations still around. Happy Listening!

Thankful, I didn't see anything so secretive about the upgrade company mod. AVM fluid on every part, wires wrapped in aluminum foil tape with cloth tape covering the aluminum. Furutech outlet with bybees on the incoming power leads. Can't tell if parts were replaced or not because the AVM (anti vibration magic) fluid covered them all. Maybe some wiring replaced and also painted with this AVM and covered in aluminum and cloth.

The RFI/EMI riddance technology might be some Aluminum tape and ferrites along with this AVM fluid which is not a secret. I saw an Oppo 95 for sale here and asked the seller to post pics of the inside of the player. The caps were not covered with the AVM fluid like the other player. Makes you wonder if everyone gets the same mod or not even though the paperwork says signature upgrade.

Thank you for pointing me to these other modders. They seem to have more of an electronics background.

I may experiment with this AVM, foil tape, furutech and bybee with an older unit I'm not using however.
