I am so glad to hear all the excellent reviews. I suspect this has been covered, but I didn't notice it as I perused the site. One of the things that really attracts me to this pre is the bass management for stereo subs. So here's my question: Anyone used the XSP-1 with nice monitors and stereo subs? Or stereo subs period?
I purchased a second sub, a Paradigm dsp 3400, so I could utilize the stereo sub feature on the XSP-1. Although I'm using them with Polk RTI-a9's on the full range output, so how much help my opinion is in regards to your question is debatable. The bass does seem better integrated and tighter that the single output on the USP-1.
Bass management works wonderfully (and very transparent) for my single sub, so why would you expect anything different when running in stereo? Or maybe you're wondering if it's worth adding a second sub? From everything I've read, I'm confident the answer is YES (the potential for room mode cancellation being one of the biggest benefits). Is it really necessary to feed dual subs a stereo signal? Guess that depends on where you're crossover is positioned (and who you ask).
All I know is if I could afford a second Fathom, I'd be all over it. Now, with the XSP, I'm even more anxious... time to start stalking the used market again I suppose.
Oppo BDP-83SE, Emo XSP-1, Wyred SX-500, B&W 805S, Fathom F112 (via Anti Mode), Samsung D7000 Plasma (OTA optical to DAC-iT), Torus Power, Belden and Mogami
I am using the XSP-1 with stereo subs (HSU ULS-15s) ond Revel F12 speakers, crossed over at ~70Hz and the bass management works great. At least for me, the biggest advantage of 2 subs is that you can simply place them next to your main speaker and end up with very smooth bass response pretty much anyplace. I had one sub first and spend days trying to find the right spot, without much luck. Two subs, problem gone.
