Oppo 203 decoding question

[63909]

Hi All,
having owned one of these and barely utilised all it can offer, I've a couple of questions if I may about what it'll do and how to connect it into an older Processor.
I'm mainly using it for Blu ray audio and SACD - so if I utilise RCA connections will it do all the processing itself and if so, theoretically, it would only need a multi channel amplifier to reproduce this?
Most new AV amps have their own processors - but as I'm only interested in 5.1 - if I did manage to use a HDMI connection - which unit is decoding the info, the Oppo or the AV?
Kind Regards and best wishes for the festive season
Joe

Yes, it will do all the processing internally using the analog outs. As long as you have a way to adjust volume, a mch amplifier will work fine for audio.

You can always connect both the analog out and the HDMI. For bluray you will probably need HDMI and a video monitor anyway just to navigate the menus. Both will work at the same time, and you can decide for yourself which processing gives the best audio result. Note that for SACD, your AVR probably cant decode it natively (although some higher end units do offer DSD over HDMI). You need to set the Oppo to convert DSD to PCM to use HDMI for SACD. The Oppo will process SACD natively and output it via analog out. That might be the biggest audible difference.

I would use the Oppo analogue outputs if possible. As has already been stated you can run HDMI to an AVR but many of those will not accept DSD and letting the oppo convert SACD (DSD) to PCM does compromise the sound. I would think that the Oppo has better DAC's than most AVR's anyway. I love the sound of my 103!

To make sure that the Oppo doesn't switch to PCM set SACD to DSD not to auto!

Thanks all,
OK time to get out the instruction manual I think! I've my eye on an old Processor which has an analogue straight through setting so whatever comes out of the Oppo will just get pre amplified then sent to the power amps, as the speakers (electrostatics) are quite difficult to drive with ' normal transistor amps' - which is why I wouldn't use a normal AVR.
Thanks again

While DSD is preferred is it not also true that if your speakers are not all the same distance from the main listening position then you need to convert to PCM to process those differences in distance. If you output DSD there is no signal processing taking place.

You will get better sound with DSD! Distance compensation is not important at all with mixes made from multitracks!

Well, I guess I'll try it.

Ah you mean from the Oppo. I never set up that stuff in the Oppo, I let the AVR handle it since it's all calibrated.
Well the speaker distances. My AVR will process DSD so no prob there.

Why does converting DSD to PCM in the Oppo compromise the sound?

 

[mandrix]

I could never hear a definable difference. I just pass DSD cause the AVR will handle up to 512.
Besides I haven't used analog outs on the disc spinners in years.

DSD sounds best in it's native format! There are many threads and posts about it. Many disagree with me but they they're all wrong! If you can't hear the difference fine, but I suggest in that case that your equipment is sub par! DSD is best left as DSD!! To me the difference is like night and day! DSD sounds more natural, converted to PCM it sounds like a tape!

The Oppo manual even acknowledges the difference in sound between the two but diplomatically says that you may prefer one or the other.

I have to try this. The problem is that it won’t be a double bind test. There is the levels matching consideration; the relay click when shifting from DSD to PCM which prevents the test from being double blind; plus I have an Oppo 205 which is superior to the 103. So lots of other variables.

You forgot to suggest ‘old ears.’
