Reasonable but not outragious interconnects

OP: I’d recommend a decent set of Canare IC’s per the suggestion of others. I’d go further and recommend Schroeder Method Dual Canare assemblies per “Celander Specification” from HAVE, Inc. Speak to Gary P. in sales.

These IC’s are far better than anything you can obtain for the same money.

You didn’t mention your sources nor the nature of the amp design (class A, AB or D). If your amp is a class D amp design, then you might not want to use these particular IC’s without first consulting the amp manufacturer about the stability of their amps with respect to potential amp (and speaker) destroying oscillations created in their amps by using these ultra-wide bandwidth IC’s. The IC’s are fine with source-preamp interconnections.

Used Grover Huffman ICs with the ZX or EX designation are excellent choices if you can find them.  The Empress and new Pharoahs are 5X and 10X your price range but the ZX and EX have most of the newer technology.

For the purpose of this conversation, I was telling a long time audiophile friend of mine I am surprised these take away from the midrange considering I was running the cheap monoprice interconnects. Figured they would be at least as good in that regard. Of course there is burn in and I have only played them for a few hours but can definitely hear the difference.  

Bingo. Burn in is C.S.O.

EVERY cable will affect a different part of the frequency range depending on the connected components.

We become conditioned to how something sounds. When evaluating, take your time. Initially impressive can become annoyingly fatiguing. Listen to a wide variety of material. Adjust the gain up & down.

The naming of cables after a dangerous black snake is pure marketing hype designed to suck you in. Read the 'story' of the Mamba II genesis here https://www.audioadvisor.com/prodinfo.asp?number=AQBMII Pure marketing baloney.

AND there is absolutely ZERO reason to use the same cables throughout. Devices differ. Cables should as well. Use the best cable you can find in the place where IT and IT ALONE sounds best.

Subwoofer cables are a bucket of C.S.O. The range in which they operate is well below where cable artifacts are most prevalent. Beefy connectors are pure marketing hype. They are delivering the identical voltage and current at 20Hz as a main amp cable is at 2KHz. They have limited need of transient response as the harmonics are outside of the frequency range they carry.

I understand there is a lot of skepticism about the value of cables and power supplies. I think one has to use common sense, as well. If your listening room is next to a construction site, cables are not your problem. It also does not make sense to put cables on equipment where the cable are worth more than the equipment. But in my experience, high quality cables and power handling do make a material difference in your sound in general if you have a decent room with decent enough equipment to take advantage of your upgraded cables and power handling. If you are skeptical. Start slow. Get Shunyata Venoms or get AQ NRG line cables. Get an AQ 1000 or a Shunyata PS8. You can buy all these things used and below retail here on Audiogon and elsewhere on the used online market. Try it. You like it? Great upgrade and sell your starter stuff. Don’t like it? Great. Sell your below retail starter stuff back on the used market. No biggie.  But I think if you have a decent room, decent music material, and decent equipment, you should hear an improvement. I personally have heard blacker backgrounds and better soundstage, amongst other improvements. Enjoy!
