Shopping for Interconnects

No one mentioned PBJ????
You might also look at Kimber Kable - note: Amazon has a lot of fakes https://www.kimber.com/counterfeits. Ray Kimber will take old Kimber in trade.  That's when many found out that the stuff they have is fake, so buy only from a legitimate dealer or direct.
PBJ interconnects are classic (pun not intended), and with a very slight discount would be in your range, and you can customize them as to length, connector, etc..  If you have any local dealer, you could expect a better discount as my understanding is that the margins on cable are higher than other audio gear. Tonic is well within your price range. Here's a review, and on page 2 there's a link to Dudley's Tonic review. https://www.stereophile.com/content/entry-level-18
I have used PBJs in the past, and thought they were quite good; nothing outstanding; quite neutral. There are hundreds of reviews of PBJ all over, and they set the benchmark for good budget ICs - for > ten (20?) years!. I upgraded to SilverStreak.
Ray also has do it yourself parts- very high quality- the same stuff he uses: https://www.kimber.com/series/diy 

On the list should be:
Canare lv-61s (detailed and punchy to my ears)
Canare LV-77s or BJC LC-1 (fuller, more laid-back)

The Belden 89289 used to be on audiophiles' top list also.
Ordering from Bluejeancables guarantees the best connectors (Canare), same with signalcables.

My budget pick:
Zu audio, you can buy their older models at a discount on Ebay.
My preferential choice:
Audioquest.

Beyond ANY doubt the ZU cables on Ebay are the best buy in audio!
Good sound and service , very honest and their build quality is excellent .
