currently my setup consists of
1. Marantz CPD 7300 (entry level dedicated cd player)
2. USP-1
3. UPA-1 x two monoblocks
4. QUAD 12Ls
with the addition of XDA-1
wont that render my USP-1 completely redundant?
why would i need the USP-1 for volume control and risk adding another area for signal degradation?
I dont have any other analoge sources
I intend to use the Marantz CDP as a pure transport, since the DAC on it is inferior to the XDA-1's DAC
hence
CDP->XDA-1->UPA-1
instead of
CDP->XDA-> U S P -1 ->UPA-1
am i making sense?
how else can i justify keeping the USP?
i dont have any other analogue sources at the moment!

If you are not going to add anything else to the mix in the future, then removing the USP is ceratinly an option.

If your only intent with this setup is high quality 2.0 channel reproduction with competent full range speakers, then there's no need to keep the USP-1.
What you'd lose:
- HT Bypass (for possible future integration into a multichannel HT setup)
- A high quality phono preamp
- A high quality headphone amp
- HP/LP filtered outputs (for possible future integration of a subwoofer)
If you don't see the need for any of that, then I, personally, would remove it.

If you are happy with your set-up, using no subwoofer. Then the XDA-1 might be right for you. My bookshelves need the help of the sub, so I have not tried out the XDA-1 as of yet.

Remove the USP-1, just as Lonnie always suggested. I don't use a preamp. I have two sources: Mac mini and the ERC-1. The latter is now a transport.
The only issue I have is the XPA-1 have such high gain than a lot of digital attenuation is needed with my Weiss DAC2. But that's no issue with your XDA-1 since it sports a digital controlled analogue volume control.

broncsrule21: I am running a 2.1 system with my XDA-1. The XDA-1 has simultaneous RCA and XLR outsputs so I have the XLR cables connected to my stereo amp and RCA cables connected to my subwoofer amp, which has an internal crossover. This works great for me.

This works great for me. I'm not sure i can do this with the sub I am running. How do I know for sure? Would I be able to do this with the Ultra 10? The little sub I use now has a "high cut" knob and thats it. |

If you look at the subwoofer apm plate on the back of your sub and it has RCA inputs and a crossover nob (usually allows you to set the crossover between around 60 and 120 hz) you can connect the sub to the XDA-1. The subwoofer crossover is important because XDA-1 will output the full audio frequency spectrum, and the crossover will only allow the the low end to be played though your sub. Yes you can do this with the Ultra 10.

I added a USP-1 to my XDA-1 for the somewhat limited subwoofer management, headphone jack (which the XDA-1 should have had in the first place) and believe it or not, a nice high quality volume knob. Got tired of the buttons, especially with the way the volume was implemented.

This works great for me. Hello, I'm running my XDA-1 using the XLR's to my XPA-2 plus running (1) of the RCA's to my sub amp like you. Do I need to connect the other RCA to my sub also? Thanks for your input on this... |

Hi Samuel, yes you need to plug in two RCA cables (right and left channels), otherwise you are only getting the low frequencies from one channel. If you only have one RCA input for your sub, you can use a "Y" adapter to for the left and right outputs on the XDA-1.
