This is a pretty important connection. I am not sure what you would consider low end. Given the combined value of the two pieces is over $5K I would consider putting in at least a couple hundred and revisit once it is all broken in… or maybe just a cheap one until it is all broken in and you know what the units sound like together and then carefully choose one to complement them.

Thank you.

Snake River Audio Boomslang AES/EBU

yes?

Can't go wrong with a DH Labs SilverSonic.

Acoustic Zen.

I’ll second the Sake River Audio Boomslang AES/EBU. I replaced my DH labs silversonic, which is great for the price.  The Boomslang was a clear improvement in my system, albeit for a lot more money.
