Value of upgrading only 1 set of interconnects?

I've had good results changing just one pair. I fared better with keeping the best pair near the source.

If the sonic characteristics of the new cable are more to your liking you should get some noticeable improvement with one interconnect and more of the same with two.  I agree to start with the source and work your way down, although it's good to try in both positions just to see what you get.  Just trust your ears.  If that means two different brands of interconnects, so be it.  There's no absolute right or wrong here.  Best of luck. 

All cables work on the principle of subtraction. They all take something away, leaving the rest apparently more enhanced.

The real question is, do you want to change anything? If so, your room is always where you should start. Cables should come last.

Best,

Don't be silly. If that were true, the Internet wouldn't work.

Thanks for the feedback, reinforces most of what I was thinking. 

Current have Cardas Sky for speaker and interconnects. 

Room is already treated. I already address dedicated power line and  regenerator

I have HF Reveal and Cerious Matrix PCs for main power and DAC, Pangea 14SE MKII for Pre. Each of these updates brought goodness, just chasing more of the same

Once the new cabinet is built I'll update PCs to the amp. I'll be able to go with 1M cables then.
