I borrowed this. I dont have nothing to compare with for this time but I think it is pretty good with Audeze more impression later.
I talked a little with CustomWorks and their goal is simple "our products are deisgned to transmit real music without distortion".
Their products is very popular in my country mainly power amps. When I thought about Hifiman HE6 I thought a lot about their poweramp HYPA 17..
They offer even highend products by name SPaudio for example their top is poweramp A400 and preamp P1 which is according to them even more real and precise then HYPA 1.
I think minus could be they do not have probably much experience with headphone, mainly with speakers..
Info from their site via google translate:
PCB size: 140 × 85 mm
Introducing a brand new discrete preamp HYPA 1, which thanks to its robust output stage and high resting flow can be used as a headphone amplifier. The recommended impedance is 32 - 600R
The input is used JFET transistors and the output stage to achieve greater efficiency constitutes BJT.
The zero offset output ensures operational amplifier, which is connected as a DC servo.
The preamp gain is possible to select 10 db or 14 db.
When used as an amplifier for low impedance headphones is not a problem to increase the bias current - amplifier then operates in Class A. The heat is removed from the final stage through the prism into the bottom.
