Hey all … I know some of you have this unit… and I have yet to see any negative review on it… For those unaware - this is essentially a USB to I2S converter that seems to mate well with the DS. All reports give it a thumbs up… These reports have been in multiple threads - and I was hoping all cou…

Just to confirm matrix have confirmed external 5v psu is outside of spec and may not work. 7-9v is the spec.

I find that I’m somewhere in the middle between the objectivists, who rely primarily on measurements, and subjectivists, who rely mainly on their ears. I believe that I’ve heard the difference better power cables, interconnects, and speaker cables make. But I’m still open to the possibility that thi…

I wish there is a set of measurements we can go by to tell us exactly what a cable sounds like, but there isn’t. The only way is to listen for yourself. If there’s enough people that say a particular cable is fantastic, then I would take notice. But the final decision has to be your own ears.

I’m not looking for something that precise. If a cable reduces noise, improves tonality, is brighter/darker, etc, then it seems like we could see a difference by measuring. I don’t know of any measurements for things like soundstage, but many of the characteristics we (including me) claim to hear sh…

I do not think we should open a “do cables (or whatever) sound different? Really???” argument. If you are a “only changes proven with measurements” type you won’t likely convert a “I heard it with my own ears” type. It will just be people on soapboxes arguing forever.

[image] jmart: Im actually getting less with it than through the DSJ bridge Something else you might try is to remove the Bridge card from the DSJ. I don’t know if you can do that on the DSJ but I noticed a difference when I removed the card from my DS DAC. Simply put, have just the I2S input…

Wow! That is an amazing thread with a lot of information. I’m particularly impressed with the number of highly informative posts from Galen. Still, there are a lot of observations without measurements to back them up. The data that is provided is about capacitance and velocity, which I can’t evaluat…

[image] shardarweb: I guess that trying new things and debating their merits is a core part of the hobby, so maybe I should just try to enjoy that more. A good perspective… But I would add that it is more important to experiment and listen in your room with your system than to debate the mer…

[image] shardarweb: Still, there are a lot of observations without measurements to back them up. Yes, and Galen is just as perplexed as the rest of us. The reason there are three “flavors” of the Icono cables - identical in construction and differing only in the copper - is (according to Ga…
