You can duplicate the Uptone USB Regen this way with about $30 worth of little boxes, direct import from the Pacific Rim via ePacket ordering on eBay or AliExpress. For extra credit you can put in a standard USB galvanic isolation chip and a new 5 volt power supply. They typically are based on a separate clock. Regenerating the USB signal is usually a big part of how USB hubs work. I think I could do the engineering with similar ease.ĪFAIK under the covers the Uptone regen seems to be a degenerate form of a common USB hub with just one output port.

Better designed DACs don't have that problem.Īs always, questions, comments, recommendations, etc. Schiit products seem to be sensitive to quality of USB power. The solution to Modi 2 Uber noise and distortion is to buy a DAC at the same price or lower that doesn't have these issues.

Finally a USB filter that actually filters! So congratulations to Intona for building a proper product that reproduces the USB bus cleanly.Īlas, as I have shown with RME ADI-2 DAC, you do not need USB filters. It is in this context that I smile when I see the performance of the Intona USB Isolator. But please go into any subjective review assuming that it could also do nothing versus "must be filtering." If you want to dismiss objective data on these products you can. Mind you, the addition while measureable, is not audible so no wonder no one is complaining about it. Instead, they add their own noise components. Based on this work, and confirmed by previous measurements I have performed, neither the Uptone Regen nor the TotalDAC D1 filter anything. So people should not assume a device is a true filter without seeing it actually measured as such. That predisposition makes one perceive improvement even if it is not there. The imagination works wonders here, equating USB and computers with noise, and assuming anything that filters it must make things sound better.

The Internet is full of praise for these USB filters. Not sure what it is about but it is extremely small. The Intona adds a bit of noise to low frequencies. Anything other than the main tone at 12 kHz is unwanted:Īs we see in yellow, there is nothing to be fixed and performance is at the limits of my measurements.

So I hooked up the Modi 2 Uber to my HP Z series Laptop, fired up Roon to play the J-Test signal to it and measured what comes out of the DAC. From past testing I know that J-test of jitter and noise is very revealing of what these devices do or don't. Wanting to get positive results, I reached out for a DAC that I know lets USB noise bleed into its output: the Schiit Modi 2 Uber. If you are not familiar with my tests, I suggest reading my tutorial on audio measurements here. Let's get into measurements and see how they do. Either way, it doesn't need a power supply. I think the TotalDAC is passive but I am not sure. The Uptone Regen which is also active needs an external power supply which itself can be a source of noise (I used the iFi iPower supply that was recommended for it). Interestingly the Intona works without any external power even though it is an active device.
