I would like to ask MR. Smith but others are welcome to reply as well.
Was the LanRover/Icron Unit the absolute highest level of USB “conditioning”? Now that it no longer works what if anything do you recommend? “If anything” Meaning perhaps as the title of this thread the DS is best off just left to do it’s thing. Without any magic boxes. There are so many of these on the market now, one hardly knows what does what. Without listening. I was not clear if you were a big fan of changing USB into Toslink? I think you mentioned that you use a Hub. Which is pretty much all any of these are. In this case it really does not matter how good it’s crystal is. Snake oil I suppose.
I have $$$ of stuff between it but it was from a previous “mistake” and hate to get rid of it. I am betting, mine too sounds better without all that. I was just wondering, if you were going to pick one product(s) to clean up the USB what they might be? Or if in fact it hardly matters to the DS? I ask this because perhaps I can sell all of that. I do not usually sell things but why I may have spent $$$ to make it worse is beyond me. Well, it is a carryover from a previous DAC.
There are so many different ways you can go with this if it is in fact going to make a difference. USB>Optical, USB>Ethernet, MicroRendu stuff, “claiming” galvanic isolation, Noise shaping devices, Moving the noise out of hearing range, and the list goes on. I truly wonder, per this post if it is simply best with a good cable and nothing else. Then there are all the Linear power supplies to drive this stuff. No shortage of those either. So would you not use any of this, or if you were to use one, which? Or a combination of things like I have(inadvertently)?
Also, as I mentioned I do not see how companies are providing galvanic isolation for USB 2.0. Since you can indeed cut the +5V line, but if you disconnect the shell almost no USB device will function. Are they going about this some other way perhaps? I cannot imagine they are lying.
Even so, is galvanic isolation the ultimate answer here? The way the input is setup on the DS I can see the topic of this thread. It just is not letting the garbage power rails into the FPGA. Unless I am just completely wrong? I think it all centers around the +5V and any noise present in the data lines. I am just wondering what product(s) is the best approach to eradicating this? If any! I figure it is okay to discuss as PSA is not currently producing such an item. Which in fact may lead one to believe that it is felt that it is not of urgency with the DS. The LanRover may have been best put to use on other DAC’s. Not sure. Although it may still be the top choice for this job independent of system.
Which leads me to, you said any high speed device shall work for this. I was told by some other people that it had to be this particular Gigabit model from Icron AKA LanRover. So it shall suffice to use anything USB>Ethernet>USB? Some run the Ethernet shorter distances, they are much less money. I did not know if those were okay too? Also, some are Bus powered, what about those? I just hate to implement this and not even realize It did not nothing. I am guessing however, that this and perhaps Optical are the last word in USB “purification”. It will be very interesting to hear if it sounds better without it then. I am just confused as which of the many units to purchase. these are computer components not Audio of course. We just borrowed the technology.
