Disservice: XLR interconnects

I was also a cable doubter but tried some used Silversmith Fidelium and heard a significant difference. Then I tried an expensive usb cable for crying out loud and that made a difference. This is some crazy business. I didn't think a cable that carries 1s and 0s could make any difference. I guess you just have to use your ears.

@dz13 are you serious about USB cable? I grew up with the notion its just carrying ones and zeroes and so what gives. Unless it's long enough where some data could get dropped. It's funny one of my senior design project was to write an error correction algorithm with encoding and decoding to ensure same data between source and destination.. Anyway, that is surprising and I might tweak and play with the usb cables..

I tried 25’ long XLR, Oppo 205 to preamp and or integrated amp. Either way, some weird noises occurred.

I tried short 6ft XLR Sony xa5400es, zero difference, I liked the locking connector, but no change in SQ. Didn’t notice any volume difference.

@rman9, I kid you not. It's actually almost disappointing because it means you have to consider paying a premium for every cable and interconnect. I bought a Hapa Aero USB Cable from a trusted poster over at Audio Circle. I got him down a bit because I said I cannot abide paying more than a certain amount for a USB cable. But dang if I didn't hear an immediate difference which was more detail in the upper range. I play music mostly from my computer which goes to my DAC (another thing I doubted made much difference and again was proven wrong) via USB. The other thing is that I use RCA cables from my DAC (iFi pro iDSD) to my integrated amp because it is a 15 foot run. When I ultimately retire and relocate everything, I can use the XLR cables. I don't want to buy a 20 foot premium XLR cable because that would be really expensive so I'll wait until it's only a 1 or 2 meter run.
