They seem to be taking some design cues from Bel Canto.

A good deal at $330 shipped and appealing looking - the chips I haven't heard much about, not sure if they're anything special...the DacMagic can be had for a tiny bit more.

Do you think the Matrix will drive my K702 with authority? The Balanced XLR is always good, but where is the spec for the built-in headphone amplifier?

I was about to try this DAC but 'coolfungadget' won't ship to my country. Does anyone else sell these?

Just a quick note.

The Cambridge Audio 840C [top of the line still at CA, I believe] uses 2 x AD1955. While I agree implementation is key, this should give a hint as to who else uses the chips.

what do some of the numbers mean (on the right)? we can see samplerate there. what else is going on? a clock or something?? scms bits? what?

I think that may be track number + time elapsed on track. It's just a guess; those values would be more commonly found on a CD player than a DAC, but that's what it says to me when I look at it.

the subcode data does have that, depending on the source. on DAT tapes (remember those?) they had start-id changes (like a track change) in the subcode data. you could even build boxes, from plans, that would pass or zero-out these subcodes.

since they are picking up the samplerate (not sure if they are sensing the actual frequency or just reading the subcode bits that 'say' what the SR is) its believable that they are also picking up other subcode data items, as well. kind of interesting and slightly unusual.
