The hd I/O sounds miles better than a blue 192-
in fact it sounds so good that I even sold my
trusty prism ada 8 xr which is almost 4 times its price.
Not shure what the mod does
but for me the hd sounds so good that I clearly
can erase the converter topic for the next decade.
Non the less I think I will mod my hd
with a less noisy fan in the near future lol.

Actually, I've always kinda liked BLA even though I don't own any of their gear or mods....but this certainly rubs me the wrong way.
Slimy, I guess.

I have absolutely zero affiliation with BLA. I own zero of their products and only just visited their site because of this thread. Please read what BLA have actually said. The are clearly outlining their technical opinion of the avid HD design. You know those electronics guys... They even mention that the D/A in the Avid HD unit is better than the blue 192.
From the BLA website:
Like most converters released under the Digi/Avid name, clocking architecture is based on the standard HC49 crystals in Pierce-Gate configuration. This is the same clock found in the 002, 003, 96IO, and blue Digi HD box. We were disappointed to see that the A/D converter was built around the CS5381 A/D chip, since this chip does not offer as good of performance as the AK5394 chip used in the older blue devices. D/A conversion is built around the Texas Instruments PCM1794 converter chip, which offers improved dynamic range performance over the Cirrus Logic D/A chip found in the blue Digi boxes. What's nice about the PCM1794 is its on-chip conversion design as well as the way the filters are etched into the semiconductive substrate; this makes it a favorite among design heavyweights whose opinion we respect. |
Sadly the new Avid boxes omit the wonderful copper shielding of their predecessor; something we imagine is a cost-saving move. Analog path in the new black boxes is not nearly as impressive as the older design, with most of the path built around the NE5532, Burr Brown OPA2227 and OPA4134. These are decent enough amplifiers, but we think that better options exist.
