Hello Mr. Grunt
I've heard a bunch, and my personal and absolute favorite is the Bellari - VP130 Tube Phono Stage Headphone Amplifier which go for about $250. This is a really terrific headphone amp and, in the event, you ever want to dabble in the heretical black arts, it is a great phono preamp. In my opinion, the Bellari is a steal.
BTW, there is a very significant difference in sound quality using headphone outs from most receivers and a dedicated headphone amp, and among those dedicated units, there is a huge difference. It won't be a surprise to Axiom folk that the quality of these dedicated headphone amps is not price dependent.
Anyway, nice chatting with you Grub, and I hope your new shift and headphone amp works out for you.
