Which interconnect cable to upgrade first


Hi,  just a hopefully simple question.   I'm considering upgrading my interconnect cable in my digital system which looks like this:

Network Streamer -> Preamp -> Power Amp

If I were to only upgrade one cable, which one should I upgrade first?   The one from source to preamp, or the one from preamp to power amp.   IOW, which will give me bigger bang for the buck.

Any suggestions, opinions, advices, or experiences are appreciated.   Thanks very much.

thanks @ghdprentice ​​​​@thyname the Kimber Select KS-1116 and Cardas Clear Reflection are both on my short list to try.  

i’ve not heard of Zavfino, but might do a little research on them.

I’ll be looking at XLR connectors. 

Thanks again. 

I have extensive experience with Cardas Clear Reflection XLRs, and I support the excellent suggestions from @thyname and @ghdprentice. There is also a long and enthusiastic review of a full loom of Cardas CR on the Steve Huff Photo website. 

I currently use CR XLRs between my DAC and preamp and between my preamp and power amps. The CR has a beautiful midrange and is extended on both the top and bottom without sounding harsh or fatiguing. It provides a hint of warmth, but it also provides the clarity and detail that is heard in the newer Cardas cables in the Clear line. It's a wonderful cable! 

I upgraded to the CR after extended use of the Cardas Parsec XLR. The Parsec is a very good cable, but compared to the CR it sounds a little softer and less transparent. Until I got a second CR XLR, I used the Parsec between my preamp and amp. I experimented with using the Parsec between the DAC and preamp, but I preferred the sound of the CR between DAC and preamp because it presented more characteristics of the better cable.

I would also second thyname's comments about the Zavfino Fusion XLR, which is in a similar price range to the Cardas Parsec. I wouldn't call the Fusion a warm cable, but it's not especially cool-sounding either. I guess it could be described as fairly neutral, but it has a naturalness and purity that is very seductive. I'm just starting to listen to a "not-yet-broken-in" Fusion because I want to move my amps closer to my speakers and need a 5m XLR to do this; unfortunately, a 5m Clear Reflection is very expensive, so a 5m Fusion may turn out to be an effective cost-benefit compromise for me.

Best of luck in your search!

Thanks @sdl4 for your first hand experience on Clear Reflection.  Very helpful indeed!
