A couple questions in one, from a long time head- fi lurker, first time poster:
I'm thinking of getting a M2tech Hiface 2 USB- S/PDIF converter (or a similar unit) partly in order to be able to use a coaxial cable- most likely a SilverStar 75 BNC cable from Black Cat. (And partly to future proof myself- laptops with optical out are, in my experience, rare). This would connect my laptop to my Beresford TC 7250 DAC (yes Beresford... bought for performance to price ratio, not because of Stan's reputation). My question concerns the M2Tech Hiface being asynchronous. Since my DAC is NOT asynchronous would using the M2tech Hiface effectively transform my DAC into an asychronous DAC... (I'm presuming there is no bottleneck between the M2tech and the DAC).
Secondly, does anyone have a similar experience of upgrading from TOSLINK optical S/PDIF to coaxial? Would the combination of the M2tech and better coaxial cable (BNC 75ohm) likely produce an audible difference? Part of me is all about upgrading my signal path, although this would end up costing $300+ (more than my DAC!). On the other hand I recognize the value of USB- S/PDIF converters as they effectively convert any old netbook or laptop or even NAS (synology ds 411j in my case) into a decent transport.

Sorry for the slightly wordy post.
