Well, a new DAC-19 has been released by audio-gd - the 10th anniversary edition.
Seems to be fairly similarly spec'ed as the older models - 2xPCM1704UK, DSP built-in, discreet stages throughout, Class-A PSU.
It has USB [can be swapped for HDMI/RJ45 I2S], BNC/RCA and optical. Goes up to 32/192KHz via USB and 24/96KHz via COAX and optical.
750USD promo, 800USD after that.
Shame they didn't release it a few weeks earlier as I might have had been interested in it. Oh well, I did not get to hear the previous DAC-19s either.
I guess this lies somewhere below the M7 and Ref10.32, directly competing with the NFB units. Seems to be a fairly interesting product. I am interested in what others think about the DAC-19 series.
