I picked up a used Nordost Vishnu for $100 which I got very lucky on the price. It’s a great cable on digital equipment; love this cable. Find the best Nordost you feel comfortable spending money on. Another thing you could do is visit VH Audio and build your own; it’s super easy. Send an email off to Chris and he’ll help you pick the best for your budget. Kimber PK 14 Golds show up here often and that would be a very good cable and used in your budget. I’d recommend not getting a big heavy 10 AWG cable; IMO lighter gauge cables sound better on digital equipment.
