Do this if you haven't: turn off auto play! It's a well-known issue with auto play that it clips a second or so off once inserted...and a well-known fix..turn it off.
I have several review snippets of the 83 vs SE on AVS forum. I've lived with both for several weeks, and made sure both were broken in for at least 100-150 hours. For DSD (SACD native) mch playback the SE runs rings around the 83, which isn't too shabby itself. For mch PCM it's better too...still worth it; DSD makes it a no-brainer. This is the 10th universal I have owned over the past 10-12 yrs or so, and it's the best (certainly for 5.1 mch), and yet signficantly less expensive than even the cheapest of those 10 at the time. In DSD mode for 2 channel the differences aren't that big, but 2 channel PCM source stuff certainly is. The soundstage width, depth, transient speed, leading edge attack (piano sounds wonderful), dynamics, microdetail are all exemplary. noise floor on the SE is quite a bit less than the 83, but this was not borne out until a full 150+ hours of break in. Donald Fagen's Kamakiriad (PCM of course) was the best we'd heard ever it when listening this past week. I've owned that DVD-A since the day it was released, and felt like I heard it for the first time. The energy was frighteningly real. The new Jimmy Cobb Live at Blue Note SACD is surreal, as is the nice sampler from Cookie's BlueCoast Records. Jane Selkye's Slow Day is sublime.
My summary is that the 9016 Sabre32 chips do a good job of DSD but a much btter job via PCM; the 9006 chips (used for multichannel) have a sweetspot for DSD that is quite quite good, and overall PCM sound is better than its standard counterpart too, making it a clean sweep The only real downside to eithe rplayer is it's speaker config/BM functionality. In the SE, especially, since Oppo is trageting analog users, the BM is fixed 80hz and the distance (delay) settings require the mains to be your furthest setting!. For me it was fine, I have identical drivers, somewhat equidistant, and trims ettings on my ana,log mch pre. For most, it's an obstacle that Oppo likely can't fix with firmware.
My 5.1 system (as opposed to my 2 channel or dedicated 7.1 channel setup) is now all-analog after dusting off my trusty Sony TA-P9000Es for mch analog fun. The SE shines in that setup. I drive my front SP Tech Revelations with Spectron Musican III Mark 2 monoblocks, and I drive my center and surround SP Tech Continuum AD's with McCormcick DNA-250's. I only mention my system cuz it;s very revealing and lets the SE shine. Net/net, my findings, in my heavily treated (25 Realtraps in my room...that's me in the Nov Stereophile Realtraps ad) room is diametrically opposed to Chucks. Go figure. YMMV.
