allo.com Posted July 10, 2017 Share Posted July 10, 2017 You need a standard one for sparky and a clean one for USBridge. Link to comment

No!!!! That means: uspcb most important! That means: usb cable have negative effect That means : iso regen helps,but not much not arrived my usbridge, don't know need iso regen or not. rikhav 1 Link to comment
hurka Posted July 12, 2017 Share Posted July 12, 2017 USPCB—which we are including free with the ISO REGEN. Carefully designed with a 4-layer circuit board, taking into account even the mass of the connectors and the widths and thicknesses of the traces, this new adapter perfectly preserves signal integrity and impedance match. IT IS BETTER THAN ANY USB CABLE! Link to comment

IT IS BETTER THAN ANY USB CABLE! Okay Now I get what's uspcb.. I initially thought that was a typo by you but never knew uptone has made anything like that I was also using a cable to connect my uptone amber to dac , and when I used adapter the changes were quiet promising So the uspcb used with anything should have good results In that sense if it was possible we could just directly connect pc to dac by a uspcb So finally your observations are that the usb cable we use to connect any kind of pc to dac has many negative effects on the sound and reclocker itself does not do much? Please compare the Allo usbridge to your uptone regen and let all know what you think About ISO regen, if it's worth or not , only once you try will know On paper , a big step up from original regen Link to comment

So my question: What's that ? Link to comment

mentt Posted July 23, 2017 Share Posted July 23, 2017 4 hours ago, hopkins said: Any chance of getting some feedback? Thanks I have couple of weeks with USBridge now. I can compare it with microRendu/lps1 combo. USBridge is more dynamic and has more air. You can say that USBridge has bigger sound and is more musical. Resolution is on the same level. It is interesting that USBridge can perform on this level with stock power supply and microRendu needs lps1 . in the end it comes down to personal taste and system. If you look at it from price point of view I would say decision should be easy my system: ATC scm19, NAD c388, Denon DAC/CD 1520 Link to comment
k-man Posted July 23, 2017 Share Posted July 23, 2017 Great to hear your views on USBridge @mentt! Were your listening impressions based on the board still having Jumper '28' still attached to the board? I really urge you to remove it, and it's far easier to do than you might think. Then power the USBridge board rather than Sparky and you will be beyond microRendu/LPS-1 territory. If you can make the connections, then if you power the boards individually (i.e Stock SMPS to Sparky, LPS-1 to USBridge) dare I say, highly suspect you will be in 'ultra' territory Link to comment
