I had thought it been posted before. But my colleague said it's not in our forum.
FA1 (Beyer Dynamic A1 Design) HiFi Headphone Amplifier
Leadtime of this amp is 7 to 10 days now because the sales is beyond our imagination. Hope it become normal in March.
1.The product uses PCB layout which is identical with Beyer Dynamic A1 and 99% same components. The components are supplied by trustworthy and professional component suppliers.
2.It uses high-quality aluminous enclosure, silkscreen technics and normative and compact design. The enclosure has not only beautiful appearance, but quite excellent heat-sinking capability. The aluminous enclosure, about 1 KG, has a large heat-sinking area.
3.It uses UPC1237+Omron relay as earphone time-delay protection circuit. Signal output of A1 also uses omron relay, but has not earphone protection function. So it is more outstanding and practical than original engine.
4.Signal noise ratio is optimized and has no noise when connected with sound source.
5.Comes with power line.

Another option of high-end headphone amplifier is Sense G5. It's hybrid design, using 12ax7 as preamplifier and solid state as output stage. G5 has 2 output, one for low impedance and one for high impedance. It can drive 2 headphone simulteneously.
Here it is:

It can drive 32 to 600Ohm headphone very well. The actual impedance is very low because it use transistors as driver directly.
