Asynch USB or super clock thru S/PDIF for $3.5k?


I posted this over at computeraudiophile, but got very little feedback, so I'm trying here. Looking for input from experienced users regarding sound quality of these two approaches. Right now I only have a SB Touch, but I'm considering a computer with external hard drive and a DAC:

Approach 1: Asynch USB. Wavelength Cosecant or Ayre QB9. About $3.5k. Just one input. Until I get a dedicated computer I would need to mod the Touch to output thru USB.

Approach 2: Super clock thru S/PDIF. PC to Offramp 4 w/Turboclock to Bryston BDA-1. About $3.5k too. More pieces in the chain, and more power cords and IC. Steve Nugent is a big supporter of this approach and says the DAC matters less IF you have a VERY good clock upstream. Initially I would use the Touch with the BDA1, then get the PC + Offramp.

All these DACs have discrete analog sections and all are very well thought of. My preferences are for soundstaging, 3D imaging, naturalness of the presentation and articulate, deep bass. FWIW, preamp is Lamm LL2 so I can only connect through RCAs. Amp is McIntosh MC275 (tubed).

Thank you!

I just replaced my SB Touch with CI power supply going into an esoteric G25U clock/upsampler (touch upsampled to 176k and reclocked) into berkeley dac direct into amps. I was thrilled with the sound until I put an ESI Juli@ sound card into my PC. I have a 10 meter aopgee BNC cable sending the Juli@ into the G25/berkeley (next room) and it totally blew away the touch. (Using JRiver 16). I loved my touch and thought it sounded great. I'm still blown away.
Lewinskih, I wouldn't be trying a usb interface anytime soon. The interface is inherently flawed. Always has been, always will be. I think PC audo is best in its purest form, through a sound card via an spdif 75 ohm output. Converting the usb to audio is just too messy to sound "right". As for controlling J River, I did install Rivermote to use off my iPad. It's okay, but looking for better. I am looking into something more versatile, which may be via DLNA.
