Few things I have learned about digital coax cables:
- BNC connectors are best, but need to get closest to a true 75 ohm RCA connector as possible.
- For cable composition, solid-core is best with silver-plated or pure silver being the desired for digital signals.
- Watch cable length. I always get 2M / 6 foot digital cables because I have experienced the reflection problems on short cables - this comes across as slightly smeared sound with a loss of resolution.
So, that being said, there are a couple of ideas:
1. Blue Jeans - Beldon 1694A with the Canare RCAP connectors. It's very cheap at $21 for a 6 foot, but I have been very impressed with this digital cable. It has beat other cables that were actually a lot more expensive.
2. DH Labs D-750. A solid-core silver plated conductor with RCA connectors that I think are closest to 75 ohm. About $200 for 1.5M or $235 for 2M.
I haven't really looked at other cables because I really cannot see spending more than $300 on a coax digital. But I've thought about building a digital cable using 2 meters of the VH Audio Pulsar Ag silver cable with DH Labs RCA-750 plugs. This is way down on my priority list because there are many other priorities - and the Beldon 1694A cable performs so well in my systems.
