Can someone please provide a summary of the balanced headphone amp options on the market that fall under the category of "affordable"? I'd like to know if there are any that cost less than the headroom ultra balanced amp, and I'm especially interested in a balanced tube amp. An amp is "affordable" to me if it falls in the same price range as any of the Schiit gear.
 
I'm looking to upgrade from my Little Dot MKIII tube amp and wanted to explore the balanced options on the market, but couldn't find much info. My current headphones of choice are the Sennheiser HD-600's, which I would fit with balanced cables if I found a suitable balanced amp. Any advice is appreciated.

Audio-GD is probably the only real option.  Cheap for what they are but still very good.

I have owned a couple of audio gd products. I found them to be of very good quality.
