Oppo 105 Analog vs HDMI?

I listen entirely to classical music, and when I listen via the the Oppo 105's multi-channel analog outs (I use the main stereo LT/RT for the front channels), the sound is rather boxy/congested and has little depth. Via HDMI, the sound just blooms! The imaging is far wider, deeper, and the sound is simply more open sounding. I find this to be very puzzling since the analog section of the 105 is so highly touted. I do prefer the m-ch outs for solo instruments since there is less of a sense of depth in the first place. Any suggestions?

(Here is my system):

DALI Epicon 2 front speakers
Martin Logan Motif center speaker
Definitive Technology ProMonitor 1000 surrounds
Martin-Logan Abyss subwoofer
Sony 5400ES SACD
Oppo BDP 105 SACD/Blu-ray player
Marantz 8801 pre/pro
Parasound Halo A51 5-ch amp

Are you sure the Marantz is passing through the analog from the Oppo without further processing? I took analog from the 105 through Cary 11a inputs set to by-pass and obtained a clean and open sound. Now stereo from the 105 goes through a Parasound JC-2 analog preamp, surround directly to the amps, and SW to a LF ARC, and the sound is superb. A 5400ES and JC-3 phono stage share the JC-2, and that's the reason analog stereo from the 105 doesn't go directly to the amps.

I'd think whatever processing that it does, if any, would be minimal. Remember, I'm referring to multi-channel, not stereo, as in your case.

While I have the 95, the hook ups for multichannel are the same (or so I am led to believe).

Hook the analog FR/FL to the main L/R analog outs. Hook the sub, C, and surrounds to the multi channel outs on the 105. On the 8801 (the pre pro I have) make sure you run it in direct or pure direct when listening to multichannel audio, otherwise the analog will get converted to digital, processed, and then reconverted to analog. That's not good.

Hopefully I didn't misunderstand what you were looking for and this helps.
