We recently did an A/B/C testing on interconnects.
A - Branded rca (Cheap)
B - Branded rca (Cheap but a little bit more than A)
C - DIY rca (3x the price of branded B - Silver internals)
Testing was done using a dared mp60, a NAD cdp and Anthony's hb8 speakers on DIY stands. Speaker wire used was a solid copper wire (Electric wire i think, Philippine copper - donated by DIY_Master)
The amp was set on a fixed volume, it was never changed. One cd was used (Audiophile Jazz 2), one track was used (track_8). All cables were tested with the same parameters (same track, same volume, same room, same cdp, same speaker wires, same listening position).
Results were: A was brighter than both B and C. B was good, but C was the best, the only difference with C and B was that C had a little more control on the highs, a little less "ssss" and a little improved clarity on the mids. I found no noticable effect on the bass.
There was actually, a slight difference in sound on all 3 cables used. I will not say it's a night and day difference. Probably a 5% change in SQ, for better or for worse. And you will only notice the sound if you listen intently, meaning - you were looking for differences. The sonic gain may be small, but for some, they would spend for that 5% gain.
We only did one because we got curious, and we had cables to test, and honestly, just for fun.
* 2 people were present, both shared the same results. This is only our opinion, or at least what we heard and should be taken with a grain of salt.
It was more of a "side quest", because what we intended was a home audition of the cdp if it would match his gears.... hehehe (I lent my NAD cdp for his testing because my cousin wants one
)
Cheers
