Hmmm, I have been toying off and on with buying another DAC although my focus has been on a DAC with ST input ---which has been steadily disappearing (as much as I have checked within $1000 price point used) to compliment my vintage Lambda end of production of quality Philips drives (CDM9pro) So I checked this out on their web page and to my surprise its not usable for transports.. Which I would think also helps DB Labs to focus on optimizing the design because its USB only. I Don't know that I will ever dabble in computer based files ,,etc. Although reading a bit just lately has me thinking about hi rez files which apparently I've been told by a user that the NAD M51 is supposed to be the cats meow.

Then I wondered if maybe the ST/glass fiber which had always been touted as a superior way of transmitting the signal from transport to DAC has been eclipsed by advances in technology so that coax or the other output options,,, (aside from Toslink which is generally known to be not so good) are as good or better than the ST option. I have no idea.
