I listed the Integra DPS-6.9 because it's still listed on Integra's website as a current product. The little I know about it is that with sound quality it's every bit as good as the OPPO 83 but I doubt the video quality is since it seems to use a lessor video DAC. But video quality isn't my area of expertise so maybe it is. It's interesting that the Integra 50.3 BR player has multi-ch analog outputs but doesn't support DVD-A/SACD.
I guess it does depend on what receiver the OP has since the Pioneer Elite 52/53 don't have mc analog outputs. These seem to be disappearing from players and receivers.
I have to admit I'm quite happy with my Pioneer players and receivers for hi-res audio. The DV48av is kind of entry level but through hdmi (either DSD or PCM) it's more than adequate. But I'm always on the lookout for another DV58 to replace it if I can find one at a great price (I'm sorta cheap

).
My rooms are lsomewhat less than quiet and my speakers are nice but not
that nice so I don't think I can really take advantage of a really good setup

, but the best sounding hi-res system I've had so far is an OPPO 83se, Audiocontrol Rialto EQ and H/K AVR 7200, with mc analogs of course (and Swan Diva speakers). But a Pioneer Elite 59txi and DV59avi via iLink came in a very close second. I think iLink is an excellent way to transfer audio.
BTW, I'm listening to Carol King's Tapestry SACD (in DSD-Stereo) on the Elite vsx-23/DV48 as I write this
