Higher end value cables

This guy has it right.....

His suggestions for Kimber & T worked for me.  Just upgrade to the equivalent ( updated) if the post is too old

Contact Jason Terpstra @ jason.terpstra@gmail.com for Virtue Audio NIrvana cables best for the money. NOT as good IMHO but also good for the money is Mogami Gold. 

Anticables should be on your list I feel. I use only their cables except for ethernet which they don't make.  I have their reference level electrum cables which may be a bit above your budget. Perhaps you could get something used at the reference level or try out their lower level ones. If you buy from them directly they offer a 30 day home trial.  Service is superb.  And a 50% trade in value for upgrades if you want to trade up.  I can say that their reference electrum cables easily bested more expensive cables in my experience, and are said to be as good as nearly any available and much cheaper to boot.  

Prefacing the comment I am about to make below to state that I am not affiliated with the person/company, but I have used their interconnects

There is a current auction for a Gabriel Gold Refection V2 which I expect can be won at a very good price - this is by far better than any cable that has been recommended to you thus far. 

Morrow Audio makes good cables. Priced from about $60.00 to $3,000.00. I used to have the MA4 RCA between my Bryston integrated and Oppo 105. It was a good match. I thought they were a little better than the Gabriel Gold Reflection V2 I was using.
