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.
Disservice: XLR interconnects
I ended up shelling out some serious bucks and buying Cardas XLR interconnects and connected them between the Luxman C900U, M10X and the hifi Rose RS150B. I am blown away, at the details and just how it bumped up the sensation of just the beautiful musicality..
I have to say, I am no longer in the camp of cables don't matter. In fact, I think folks who say cables do not matter are doing a great disservice to the audiophile community.
