It was almost like there was an effect on this output. When I switched to the dedicated analog stereo outputs, this completely disappeared and the sound was fabulous. What's odd is that while listening to higher resolution media like SACD, this sound could not be reproduced on the multi-channel outputs. So, I'm noticing this oddity with compact discs only. This is not acceptable because I will be using the multi-channel analog outputs for the near future.
I performed more testing in the last 45 minutes or so. The peculiar sound that I was hearing last night? Well, I'm not hearing it anymore. Don't know why and I'm not asking.
While doing some tests on the sound quality of each set of outputs with multiple disc formats, I noticed a couple of things. The dedicated stereo output is more robust in sound quality. Whereas, the multi-channel output seems a bit laidback, as opposed to up front. I like the sound of the dedicated 2-channel output (I feel that it's much clearer - detailed - in a good way) but since I will be using the multi-channel output, I feel that I won't miss the dedicated outputs (as good as they are) because I actually prefer a slightly laid back presentation. The other thing that I noticed is that with the 83, you can really tell the difference between what format is playing. Great CD's sound great and poor CDs sound poor. Plus, what really surprised me, other than going from CD to SACD, was when I played an HDCD Disc. It was like I was listening to a higher resolution disc on par with DVD_Audio or SACD. Whenever I played HDCDs before, they've only slightly sounded better than a regular CD, if at all.
Between high resolution Audio/Video now, it's making it harder for me to listen/watch inferior product (i.e, CD & DVD). Bring on the higher resolution Blu-ray Audio!
