As a dac. Fostex CR200/Harmon Kardon HD7600/Sony JA3ES --> Matrix Mini-i --> Rudistor NX-03 --> SA5000/HD600/CD3000/A1000X. Out of the box new so SQ impressions should change. Very clean, quite. Overall I like the sound and presentation. Better than the 707 SuperPro DAC I was using.
Built in headphone is also very quiet. At first sounds a little lush and sizzle-ish. Smoothed out in just a few hours. Bass was lean but also improved.
Multiple inputs is great. Selector/volume knob is push button/infinity dial style. Display of track info on screen is cool. When played from DAT and MD. Just track counter from CDP.
USB -->Mini-i HP out. At first the same lush sizzle sound but soon became more detail and dynamic. There are many sonic qualities in the Rudi that out shine this amp but for some reason I enjoy this amp more. I can listen louder longer without fatigue. It could be the lush/sizzle that I think I hear. Kind of like listening to a electrostatic. Maybe. Has balanced out for future upgrade. I was using the Rudi+707DAC as a desktop system. This with just a few hours has been quit impressive so the Rudi may have to go soon. Its smaller, lighter, doesn't have the bold hi-fi aficionado looks of the Rudi but the small setup suits me and man can I enjoy the music. Best yet, I think I am the first U.S. buyer and since no one dared to try it, I got it for the starting bid of $299.
