Strong Recommendation: Echo Audiofire

I'd like to take a moment to HIGHLY recommend the Echo Audiofire range for those who have firewire at their disposal.

Here's an RMAA at CD quality, and at 24bit. I've captured higher on 24bit (up to 115DNRA) but this seems to be the average.

I'm using an audiofire 12, which uses the same converters as the rest of the audiofire line (and several others).

For CD quality, this is extremely close to perfect for an undithered signal

It's a fairly cheap, mid-tier dac for 24bit as you can see (though to beat it in 24, you're looking at 3k+ for as many inputs and outputs as my $500 audiofire 12 has), the CD quality performance is exceptional

Just some notes:
 As it's not class compliant (it uses its own drivers), it's less user friendly than some.
I'm not sure the Audiofire 2 (the cheapest one, which uses the same things measured above) is usable as a stand alone dac away from firewire. I know the audiofire 12 is not, but the audiofire 8 is.

The AF2 can be had for $200 or so. The AF12 I got for $500, which I believe is roughly the price of the AF8 as well; both of which are capable of doing bluray playback over firewire (and I think the AF 8 can over optical too, but you'd have to check)
Cheers.

Edit: If you have questions about the software, feel free to ask

Edit:: Asked mods to move to computer as source (woops)

I do believe they all use the same dac now after there were problems with the CL chipset.

I'll take some pics of internals later on.

The CD performance is exceptional from a technical perspective for the price

I know my Audiofire uses the new dac because the firewire bezel faces the opposite direction to what the originals did. I work across weekends, so I'll get you the internal pics during the week

I get about 1ms for stereo playback, and about 10ms total (5 in 5 out) for playback of multiple channels + synth input
