Would these adapters cause signal degradation. I would love to share speakers with my soon to arrive (hopefully) XDA-1, and my Denon receiver. Any thoughts from the more experienced out there?

Trying to look for the best solution sharing both DAC and Proc. Hopefully somebody share their choice.

I don't know how accessible the back of your XPA-2 would be, but you could connect the UMC-1 to the unbalanced inputs, the XDA-1 to the balanced inputs and flip the switches at the amp to choose between them.
That may be inconvenient for you, but would yield the best possible sound quality from your XDA-1.
Just a thought.....

^ This is one alternative that I was thinking but; That constant switch change may eventually damage the switch?

^ This is one alternative that I was thinking but; That constant switch change may eventually damage the switch? Don't know, but after thinking about it a bit further, since it's something that's intended to be set only once, it may be likely..... Maybe your "best" solution would be to introduce a USP-1 (or better yet, an XSP-1) into your system. Much more costly than a splitter, I know, but would achieve a new level of performance from your system and resolve your connection issue at the same time. You could run analog to and from your UMC-1 (in "Direct" mode), but would lose the use of your sub. |

wouldn't these work emotiva.com/xrca1x2.shtmprobably higher quality than the monoprice product I would imagine that the output might be able to be used as inputs and vice versa.. thoughts? |

i think you meant from the outputs of xda-1 and umc-1 go into the inputs of xpa-2(amp?). as long as you have one unit turn off, either xda-1 or umc-1) i don't see any bleeding issue can occur. and i think the monoprice signal splitter is more convenient; with the emotiva splitter you need one more pair of rca cables for complete connection. |

I don't think the Emo splitters will work since they appear to be directional (1 input to 2 outputs). You'll need something like a piggyback RCA cable, but I don't know anyone that makes a higher quality cable other than these. www.radioshack.com/product/index.jsp?productId=3526365 |

I have my system setup so that the DAC and phono stage can drive the amps directly or my MMC-1 can drive them for movies. Everything in independent and uses the same amps and speakers. I use a passive preamp to do this. Kind of a spendy option though.

Emotiva's splitter would have no way to know which way the connections are being used. It is simply a Y connection and can be used to split or combine the signals. Just make sure you don't have the UMC and the XDA powered up at the same time, if you use this method. |

Even though one source is off, there is still power to the unit. Is there any kind of voltage or signal that could be potentially sent out while the unit is idle? I ask this because this type of connection concerns me because there is not hard shut off for the source that is off and it may introduce unwanted signal introduction into the line. This kind of defeats the purpose of splitting the units so they run independently and that there is the potential of damaging a piece of gear. When I think of something used to combine signals, I want both signals to go a common point at the same time. In the case of using a different source at different times, that is exactly what is not wanted. |

Hello, ...Maybe your "best" solution would be to introduce a USP-1 (or better yet, an XSP-1) into your system. Much more costly than a splitter, I know, but would achieve a new level of performance from your system and resolve your connection issue at the same time... This is what I'm looking at doing if I don't punt on the XDA-1 and go with a much more expensive Benchmark DAC1 HDR. The XSP-1 solution requires an extra set of cables and has a longer signal path (for stereo listening) than what would have been necessary if only the XDA-1 had been designed with an analog passthrough. I've seen several threads that discuss this common integration problem. Perhaps if there is enough discussion, Emotiva will pick up on this and see it as an opportunity to produce an XDA-1P that includes two pairs of analog inputs (RCA and XLR) and an HT passthrough button (similar to what's on the USP-1). Even the Benchmark is not quite what I want. I don't want another analog preamp! I just need a way to share one pair of amplifiers/speakers across (what are effectively) two different systems, with the shortest signal path and audio purity weighted more heavily towards two-channel listening. My whining asside, if you need analog bass management, adding the USP-1 or XSP-1 starts to make a lot of sense. You're not going to get a solution for that from a pair of Y-adapters! |

When I think of something used to combine signals, I want both signals to go a common point at the same time. In the case of using a different source at different times, that is exactly what is not wanted. Judd You are absolutely right in being concerned with using the Y-adapters. One forgetful moment could prove to be disastrous. Even if you were the only person to operate the system, the potential for mistakenly powering up both pieces at the same time is just too high for me to even consider using this connection. WARNING... use this approach at your own risk!!! Yes, it will work; and, if you are the sole user of the system you MIGHT be able to always make sure that only one of the two components are ever powered on at the same time -- but you would be making a HUGE GAMBLE. There are a lot of other ways one can achieve the goal without taking the risk. Various vendors make selection switches for RCA/XLR connectors. I owned one years ago. I think it was a six way switch from JVC, and IIRC it cost around $50. This was 20 to 30 years ago, but I am fairly certain these devices are still made today. Even a little manual two way switch would do the job cheaply. It would not be as convenient as a remote control switch, but it would be a lot safer than the Y-adapter. Even the risky Y method can be made safer if you use a remote control that works with macros. Just program it to turn the power off to the piece not being used BEFORE powering up the piece you want to listen to. The most elegant solution would be to use the XSP-1 to tie the pieces together... use the HT Bypass switch while maintaining the balanced differential signal path for the XDA-1. |

^ Just another though; Can I connect the XDA-1 RCA output to the UMC-1 RCA input (Direct Mode)? Any difference in sound quality using this configuration than the option above? You could do this but you would be loosing some of the sound quality simply because you would be going from a fully balanced signal from the XDA-1 down to an unbalanced signal path in the UMC-1. That is the same reason Lonnie pointed out that you would get better sound quality by going direct from the XDA-1 to the power amps versus sending a signal from the ERC-1 CD player to the XDA-1 then to the USP-1 on its way to the power amps. The soon to be released XSP-1 is the elegant way of solving this issue. The XSP-1 will have a fully balanced signal path and will have the HT Bypass switch... allowing you to maintain a fully balanced path from source component all the way to your speakers, if you are connected to a balanced amp like the XPA-1. |

In my case if I'm going to use the XPA-2, that fully balance signal is lost in the XPA-2, right? The other question; still going unbalance, connecting the XDA-1 to the UMC-1 (directMode) to the XPA-2, am I still have the chance to have a better stereo sound quality than the UMC-1? |
