OPPO BDP 103/105, sound quality???

For those with the OPPOMODS Liner Power Supply the large toroidal transformer responds very well to being wrapped in mu metal. I should also mention the circuit boards in the Oppo should be isolated against the 60 cycle hum of the toroidal transformer. This can be accomplished by mounting the transformer on cork or viscoelastic material. The bolt holding the transformer should not be tightened down all the way.  And the standoffs of the circuit boards should have small cork squares inserted where the screws are located on the circuit boards. 

Not sure about in the States, but in Melbourne, Australia I was able to purchase the Cambridge BD-752 brand new for half the RRP of the Oppo 105D. It was a no brainer at that price.

I personally prefer the BD-752, finding it more "musically involving" than the 105, which in limited listening was a bit too analytical and etched for my tastes.

The Oppo has a few extra features which I have no requirement for.

So if you can pick up a Cambridge at a good price that's the way I'd go.

Too bad this thread stalled out 2 years ago. About 6 months ago I found an iEC silver/Furutek Rhodium IEC wiring harness on ebaye that was a jaw dropping improvement. That led me to do an easy DIY swap out of the OEM board for a Linear Power Module

Amazing

FWIW, I have never put much stock in tweaks, or upgrades, believing that they are just snake oil. That was my error. I had my Denon 3520 (from the early 90’s) modded recently and it is like a new machine. I would never attempt upgrades myself but I do believe that tweaking, specifically updating older machines, makes good sense.
