@sns Yes, I agree the streaming possibilities today are numerous and endless. Endless too is our individual climb up the audio mountain. At certain stops, we may decide the view is too nice and stay put. Other times, we continue the climb up to seek a new view. We all have done both and both are perfect choices for the moment. Right now I’m on that next climb but I plan to stop and enjoy the view once the Fiber Box II arrives and is inserted into the system. I need to "rest" and just enjoy because I’ve been moving up at breakneck speed. Regarding optimization of particular digital input types, I don’t think we can say one type is definitively better than any other type. Based on my own experience, I believe the optimizations that one can do is limitless for any digital input type. We can just pick what we think is best and optimize (endlessly if desired).
@lordmelton I would like to describe the same type of test I did almost a year ago to provide another perspective. The DAC under test was my Benchmark DAC3 DX. The AES setup was the MU1 but the AES cable this time was a $56 Grimm TPR cable. The USB setup used an $8K USB solution whose main components were the opticalRendu, ISO Regen, Phoenix USB, and Shunyata Alpha cable. This test would decide if the MU1 would be heading back to the Netherlands or not. As we know, I kept the MU1 and sold most of the USB solution. Of all the musical qualities that I cared for, this AES setup was preferred roughly by 80%. So I still thought the USB setup did some things better. Having decided MU1 AES was my future, I replaced the TPR cable with the Omega cable. I’m going by audio memory here but the MU1/Omega combo then tipped the scales nearly to 100% AES. I had sold most of the USB solution by the time I received the Omega cable so I couldn’t repeat the test. Lesson reaffirmed: digital cables matter greatly. Regarding DOP, the MU1 does support it. I believe I have an album or two that is DSD so I may give DOP a try, if anything, to learn something new about the 005 and the system as a whole.
@melm I was aware of what that head-fi user did but I was not aware of how easy it is to remove and re-insert the USB board. Thanks for sharing this info. I’ve replaced the DSP boards on my Kii Three active speakers so removing circuit boards from high end gear would not be new to me. I will remove the USB board from the 005 and have a listen and then report back. I’m expecting to hear a difference because the main premise of removing any piece of circuitry (if it can be done and is not needed) is to not suffer the noise/distortions caused by that circuitry. Side note: If removal is not an option then reducing the activity level of any circuitry should also reduce the noise level. This has been my experience.
