Posted the updated specs from m903_manual_RevA.pdf in the OP.
I find the grace a bit fatiguing compared to the Grace. The Grace does have myriad inputs / outputs which is a huge plus. Both units fit nicely on top of my PC chassis which is big plus. I would like to see someone run the Balanced outs ( TRS ) into some HD-800's and see if there is something of interest there. Anyone?
I got my m903 a couple of days ago. I compared the sound quality of both the DAC section and the headphones amp section to those of the Benchmark DAC1 HDR. I used HD800 and HE-6 headphones for the headphones amp comparison. I used an SR-007/KGSS combo and also Focal Twin6 powered studio monitors for the DAC comparison.
Bottom line - no significant difference in sound between the DAC1 HDR and the m903. This applies to both the DAC section and the headphones amp section. This is a good thing and what I was hoping for since the DAC1 has excellent sound quality.
Since the m903 offers comparable sound quality to the DAC1 at a comparable price, but a better feature set, I would highly recommend it.
[size=10pt][size=10pt]I believe at this point the lack of bass emphasis with the Grace is a combination of the HD-650 roll off, impedance as a function of frequency on the low end, and the brightness of the amp. The hardest thing for amps to do, in general, is to produce solid well controlled bass. Same goes for headphones really.[/size][/size]
