I have had the Eximus DP1 in my possession for just under a week now, and I thought I would share my personal observations. Please bear in mind the unit has had no 'burn in' time (if it needs any).
Firstly, I used the DAC as a direct replacement for the Cyrus DAC X/Cyrus Power and Halide Design Bridge using my Rudistor RP8 and HD800's with a dedicated music PC fitted with SOTM PCI USB and SATA filter. The sound appeared slightly more focused, but not a huge difference. It really does remind me what a good DAC the Cyrus is.
However, the biggest change came when I used a friends Macbook Pro with a trial version of Amarra, and Audioquest Diamond USB cable. This really did make a big difference. The Cyrus/Halide could not compete with this. The sound was very analogue and really enhanced the tube stage of the Rudistor. To me, an incredible sound that really reminded me of vinyl. something I could never find weary.
The next step was to remove the Rudistor RP8 and run from the Eximus Headphone Amp. The sound is incredibly similar. I blind tested this on my wife,and she couldn't tell the difference.
I have now decided to sell my Rudistor RP8 amplifier (along with the Cyrus and SOTM gear). That is how convinced I am by the Eximus. For me, the rest of the equipment is now redundant. The next step for me is a Macbook Pro solely dedicated to Amarra playback.
I agree with Neogeo's comment that Anaxilus has a duff Eximus, as it is definitely not the same animal I have.
