Honestly, if I didn't already have an Oppo unit, and if I didn't already have a small collection of SACDs, DVD-As, and Blu-Rays - in other words, if I were just now confronting the choice of whether or not to get into high-res optical discs - I probably would save myself the money and aggravation, and just get a good DAC and decent CD player or transport. I would use that setup to play my CDs, and for high-res I would rely on streaming digital files from a computer or dedicated streaming device.
Not trying to take the thread off-topic - it's just that there are now vanishingly few choices for truly universal disc players, particularly ones that offer all the features of the Oppo 105/205 and are affordable. What there is now - for example the Pioneer and Panasonic units - are basically Oppo 103/203-level machines, at prices that are close to Oppo 105/205 prices. Not worth it IMHO.
