Oppo 105 stock vs Oppo 105 Modwright

This might help. It's the 6 Moons review of the Modwright Oppo 105: http://www.6moons.com/audioreviews/modwright11/1.html

Combine the Absolute Sound review of the stock 105 with the 6 Moons review of the mod and you'll likely have an accurate picture. http://www.theabsolutesound.com/articles/oppo-bdp-105-universal-blu-ray-player-and-dac/

I have the ModWright Oppo 105 and can switch between the stock and modified very easily. The ModWright tube mod with the right tubes is on another level. The ModWright capacitors and beefy external power supply brings a fleshiness and wholeness to the music and with more detail. To me me the ModWright brings more emotion to the 105.

I HAVE directly compared the OPPO 105 to a 95 Modwright in a system somewhat unfamiliar, but the results were clearly evident. The Modwright is just as Talk2me notes, more whole and full and MUCH more dynamic. The mids, particularly vocals took on a more natural presence and then of course the dimensionality was enhanced which you would expect from a tube output vs op amp. I did perceive a notable improvement from the stock OPPO 95 to the OPPO 105. I can't imagine how much better the Modded 105 is from my Modded OPPO 95 with the Bybee rail and audio magic pulse gen zx adds to the mod. The Modwright is just in a different realm from either stock version which are VERY good at the price.
