The Oppo is not going to weigh as much or have as solid a feel as a high-end player. If microsonics is important to you and heavy metal construction is a priority i don't think $1200 is going to get you there. The DAC has to be incorporated into a component with a well-designed analog stage, 1st class connectors on the back, isolated power supplies, etc. OTOH, cdp's have come a very long way since the Sony SCD-1 player was introduced, and as has been observed by so many, Oppo has overcome many of the price/performance barriers that used to separate the high end from mass-produced units.
The 105 is however has more "video" refinements over the 95, and i wouldn't want to call it a SOTA 2-channel player by everyone's definition.
as far as Modwright alterations go, you're looking at an outboard power supply, an umbilical, and tubes protruding from the top of the player. their
reputation is very good but by the time you consider getting the best umbilical vs the stock wire, various power cords, different tubes, etc., that should be a set-up you really are going to want pretty badly (or not).
