Wyred 4 Sound STP Special Edition Vs. Pass X-1


Does anyone know how these two stack up against each other? The pros and cons. How does the quality of bass, midrange, trebil, soundstage etc. compare?
Thanks for your input!

Not to far off topic! I have considered the XP-20 but too much cost for me as these are still realy new. I love my X-1 but I need something a bit more versitle hook-up wise. I'll post here how I like the Aesthetix.
I've got a Cary SLP-05. I loved this preamp but honestly, I wish to get away from tubes. I'm constantly tube rolling! I just can't leave well enough alone.

New baby wants my time but loves music too (I think).

Now I want to set it and forget it, but don't wish to sacrifice what I've got going DAC to amp.

Interested to hear what good audiophile folks have to say here.
I love tubes, but I can't find any quiet enough for me in a preamp. Tubes do have their virtues and I can see why many like them in the preamps. I would never say they were a bad thing.
Srwooten,

I would like to hear your thoughts on the Aesthetix Calypso preamp when you get the chance. I have briefly compared it side by side with a Pass XP10 at the local dealer. IMO, the Calypso had a deeper soundstage with exceptionally pleasing tonality, but the Pass created more of the "you are in the room presence" specially on female vocal tracks. I am zeroing on these 2 units and might schedule an in home demo shortly.
