RME Fireface 800 vs. UA 4-710 converters

I did a test this morning.. I was wondering how different were the converters in my fireface 800 and my UA 4-710 (going to the RME with ADAT)

The setup : The 4-710 offers 4 preamps with line out and ADAT out.
I play strumming notes on a acoustic guitar, plugged in the Hi-Z input of the 4-710 and recorded both signals (line out and Adat).
I use Fabfilter Pro-Q matching EQ fonctions.

The white line represent what the EQ would need to do to match the 4-710 to the RME
So as I can see it the RME has slightly more bottom (which I get the feeling happened when I an opened chord at the end).

I should say that with the monitors, the room and ear training I have, I can't hear the difference or decide which I like better. I wish I could have more converters to A/B but at least you'll know how close those 2 are ;)

.... it's just a dB or 2 across the spectrum but over a lot of tracks it could add up. i think you would hear more differences when you recorded several tracks with each ...

Interesting. It's kinda affirming my thoughts on modular conversion, and pairing the conversion with particular pieces. Same idea with stacking 'analog saturation' plugins, and even compression to an extent, where in the analog realm there would be more variances due to tolerances, condition ect.

If you post the files I'd be curious to hear in my living room on mackies, if I could tell a difference. I'd be surprised if it was really noticeable.

They are very crude plugged acoustic guitar direct to the DI input of the 4-710. But I think they are valid exemple of the difference between the line output and the ADAT...
What I can't tell is if the difference comes only from the converters or from the analog circuitry of the line out of the pre... ;)
