Which interconnect cable to upgrade first

@xcool.  “Lumin T2 -> Parasound JC2 -> Parasound JC5 ”
 

Nice, elegant well chosen components. It is nice to see a system like this. Given the equipment I would go for neutral with ever so slight touch of warmth. I would give a consideration to Cardas Clear Reflection. I think that is in the price range. You can never 100% know the result of an interconnect but to me this would have just a touch of warmth and coziness to the sound.

My recommendations for your new interconnects (by the way, sorry if I missed this, XLR or RCA?):

1 - Since you are a Kimber fan, take a look at KS (select) series. Even the copper ones like the KS-1116. Yes, pricey, but they are extremely good, and you can find them online used much cheaper

2 - The Cardas Clear Reflection @ghdprentice  suggested above

3 - Zavfino. These are extremely good for the price. Not a mainstream brand like Cardas and Kimber, but very good value for the money. Example: the Fusion RCA or XLR 1.5 meter pair for about $300: 

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. 

You are welcome @xcool 

As for Zavfino, there is a most recent thread running here: 

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!
