Its certainly one of the least digital like DAC's I have ever heard, which is why I purchased one!
I presume you are using it through USB?
Either the DAC is faulty or the problem lies elsewhere I would suggest.
Yes I was using usb with the appropriate driver.
Just as a reference, I did NOT hear a difference between 100 and 200 hours of burn-in. Burn-in was done with a combination of "Purist Audio Design - System Enhancer Rev-B" and "The Orb's - Orbus Terrarum".
I sent back the unit to Mike from Magenta Audio and he initially thought that there was something wrong with the Dac. He had it burning in over night and reevaluated it the next day. He said that the extra burn in time significantly helped to 'smooth out' the harshness that he heard the day before. He also said that in his 20 years of experience that digital devices like this need at least 500-600 hours running time before 'The Transformation' happens.
I find it very difficult to believe that burn-in of this nature would make all the difference when 200hours didn't seem to make much. It would have been a good idea to record a track before and after burn-in with an A/D converter just so a direct A:B comparison could have been done
If one is listed on StereoNet with good use, I will try to audition it as the first unit I had could have been faulty or needed the full 600 hours.
Experiences with sound given how all our ears differ so greatly can be difficult to convey via terms like warm or natural or neutral. I will try to convey it in terms of a photograph.
If the music were a good photo, the Octave MKII up-sampled the pixel count and turned the Contrast and clarity way up. In comparison, a friends all vinyl system would sound like the photo's clarity was turned down and the colours were a bit blurred & saturated in a slightly dream-like way... both seemed like polar opposite ends of the spectrum.
Tell me if using photography terms to describe audio is going beyond being a wanker.. lol
