Warm interconnects recommendation

Most anything Straightwire or Cardas.

In my evaluations, Cardas is rich. If your system tends to be bright and thin try Cardas Cross or Golden Cross.

anything from Cardas has a warm sound

Where does the Kimber Timbre and Hero interconnects fall in terms of warmness and general performance?

Also intrigued by the Dimarzio M-Path but there doesn't seem to be much literature on these.

DiMarzio M-Path.

I believe you would enjoy the sound of ACOUSTIC ZEN martix reference 2s in your system. They have a wonderfully smooth and full organic sound with excellent details and a large and layered soundstage. You should be able to find a used pair for around 200.00 dollars. There a little more than what you said you wanted to spend, wellworth the few extra dollars in my opinion. Remember, you want the MARTIX reference 2s not the first generation of this cable, which was good but much improved in the second generation.

Yeah Truth links are not warm, but more neutral sounding.
Warm considerations are Cardas Cross, Audio Quest Python, MIT's stuff, any Monster cable basically, etc. Good luck

I have found Synergistic Research actively sheilded alpha and kaliedescope cables to match very well in my system. I have Musical Fidelity electronics and B & W 802 matrix speakers. The cables were just warm enough to keep the system from being overly bright. I big improvement over silver cables I had before, which matched better with my old Spica speakers.

Carda Cross is all about warm. Considering that a new pair goes in the low $400s, a used pair for $200 is not a bad deal at all. Cardas does not hold it's value as well as others, so you are getting a lot more for $200 than you will get for $125 IMHO. The Cardas Cross was my first step into higher end IC's after going up the ladder with Kimber's PBJ, Silver Streak and Hero. The CC is definitely warmer and cleaner than all of those IC's. If you can come up with $300, you might be able to be happy for a long time with a used Audience AU24. I just went from a $1000 pair of Acoustic Zen Silver Refs to the $500 AU24 (new prices), and while AU24 is not as detailed as the AZ's, it is not as colored either, and I can listen to all my music not just some of the best recorded stuff. I still have my Cross which I use on my cassette deck mainly because I bought it new, and I can't get anything better for the $200 I could sell it for. For fun, I compared the Cross with the AU24, and they both are warmish with the AU24 providing much more detail. Good luck

You can also check with the manufacturer of your Zu Oxyfuels in regards to their other interconnects such as the Zu Gede.

Try the original MIT MI-330....tube sounding interconnect...
I have a pair that I no longer need.

Cardas Quadlink, seem to me to be exactly what you're looking for.

I've been intrigued by the Cardas Cross, but they seem to go for at least $200 used

You can get a used Cardas Cross in that price range. Very warm.

Cardas Twinlinks 300B. Not bright, edgy, or expensive. And, IMHO, its good enuf to be a benchmack should you decide to upgrade cabling at a later date.

harmonic technology truth links. Probably more neutral than warm with a full body bass. Cheap these days as well
