    My Denon A1UDCI has finally arrived!!

    I have been wanting this player ever since I first learned about its development last year, and now after a very long wait I finally have one.:)

    This player is as good as it gets for both PQ and sound. As much as I loved my 2500BTCI, this player is in another league! The images from Blu-ray's have a dimensionality and extra detail that makes the 2500BTCI look flat by comparison. Listening to CD's via the balanced XLR's, using the players 32 bit AKM DAC's, is a real treat! My Sony XA20ES CD player has been my reference player for years, but the A1 edges it out.

    So far the A1 is very impressive!

    Here's some pics.

    Why did you use XLRs?

    Glad you're happy Seth!

    I have heard that it only matters on long cable runs. In fact that's the mantra of another forum. Is that true?

    And just because a component has XLRs for input or output doesn't necessarily mean that the component is balanced. Do they do this to take advantage of the unwary?

    I have been told that unless you can get all the way from the source to the amp with balanced don't bother. In my case, my cd player has xlr outs, my pre/pro has both ins and outs, but my amp does not have the inputs, so I would have to go back to single ended (rca) for that run, and doing so would negate any gains I made earlier in the run. So I didn't buy any xlr interconnects.

    Noise generated within the cable would still benefit, TTBOMK.

    And again TTBOMK, long runs do benefit more than shorter runs.

    So should one use them if they're available?

    A cable, being passive, would probably generate very little noise. A balanced cable is likely to pick up less environmental noise than a single-ended cable.

    I would say, yes. At worst, you're no better off than single-ended. Depending on the design at either end, it only has the potential to be better. This is assuming there isn't something totally broken in the balanced design in some component, of course.

    That's one possibility :) IMO, the big advantage of an XLR cable is a separate shield (with RCA, the shield is the ground/negative signal connector). So even if the input isn't balanced, it's still likely that the shield connector goes straight to earth, bypassing the signal circuitry. So you gain the advantage of not dumping any RFI that got picked up by the cable into the signal's ground.

    Like I said, there's a potential for improvement. Whether you'll actually hear a difference or not depends on many other factors :)

    Might as well add a 4th post while I'm at it...

    Thanks Artie.:)

    The reason I used the XLR's is because the player had them and I have been wanting to use the stereo XLR inputs on my Denon AVP pre/pro ever since I got it a year and a half ago. My Sony CDP-XA20ES doesn't have an XLR out option, so I've always wanted to have a player that did.

    I did a test on the A1UDCI comparing the stereo RCA outs with the XLR's. As everyone probably guessed, they both sounded excellent! But the presentation of sound was very different. Sound through the RCA outs was more forward. It wasn't bright or harsh in any way, but the whole soundfield was more up front. Sound using the XLR's had a more laid back sound that was smoother and silkier. It could almost be described as having a touch of warmth.

    I liked the way both sounded, but could probably spend more listening time using the XLR's over the RCA's. But it's really just a matter of preference.

    I am so jealous. You did a wonderful job with your theater. I really admire the new player. As mentioned before I have the Denon transport you have, but just could not move up to the universal player. If it is that much better than the 2500, I am really sad I did not go ahead and spring for the big one. Having said that, I do like the image from BR discs on the 2500 very very much.

    Thanks Seth, that's interesting.

    I am puzzled that the RCAs and balanced interconnects sounded so different. Where they otherwise the same cables (i.e., same manufacturer, same materials, etc.)?

    Thank you for the kind words.;)

    Yes I agree, the 2500 is an excellent Blu-ray player, and one that will continue to be used in my setup (as a region B player). It has proven itself to be totally issue free, and delivers a superb high def picture. And if I was only looking for excellent PQ along with SACD/DVD-A capability, and wasn't concerned about fully balanced 2 channel XLR outs and Denon Link, I probably would have looked into getting the new Oppo. But for me I wanted the best player I could get regardless of price that had everything I wanted, and that player happened to be the A1UDCI.

    You're welcome.;)

    The cables "might" be a factor in the overall sound. The XLR's are Audioquest Columbia with 72v DBS system, and the single ended interconnects are Outlaw PCA's.

    I daresay that is the reason they sound so different, not because one is RCA and the other XLR.

    After wanting ML speakers as rear surrounds for some time, I finally got me some.:) I got a great deal on some Scripts, so I took down the Paradigm Mini Monitors that were on the rear wall and replaced them with the Scripts.

    I have to say I'm pretty impressed with the sound.
