A hard look at the effect of cables

Hey guys
A fellow EE audionut directed me to these articles and I thought some of you might be very interested to read them too. Two arguably qualified engineers went through the pains to take high quality measurements of the effect of cables and their interation with a complex electrical load, such as a full range loudspeaker, and with a complex signal, such as music. The link below is to the final installment but be sure to also read parts 4 and 5 very carefully. Part 5's Figures 6.8 and 6.9 are really amazing. I had never seen such measurements and they definitely seem to correlate with what we hear. The cables lengths are longer than normal but I think the point is well made. Hope you enjoy this read as much as I did.

my personal experience points to the source as having a significant affect upon the performance of a stereo system.

thus, the signal from a cd player passes through 2 interconnects and a preamp before it reaches the amplifier.
it is this link that has a greater audible impact than that of speaker cable, amp and speaker.

the signal fed to the amplifier is critical, for obvious reasons.

hi shadorne. there are two cable interfaces that you may be overlooking, namely the source to preamp and the preamp to amp. what about transport to dac. and what about line cords ?

ihave personally observed affects of line cords with respect to the above mentioned interfaces.

by the way, i am not aware of any panel that is fully active. some provide an amp to a woofer driver, but then the owner must furnish the amp for the panel.
