Yulong A100 Class A Headphone Amplifier

Previously used the Shanling PH300(0) with my Grado GS1000, which was not a good match. The Grado sounded way too harsh and tiring, already after slightly turning the volume up.
As a result, I purchased the Yulong A100, which was basically another wild guess, despite the positive review on HF. I am very happy with the sound the GS1000 produces when powered by the Yulong A100, which is tight, airy, punchy bass, detailed and musical.
Altogether I can really recommend the Yulong A100.
 
A few comments to the designer, which could be considered for an I(improved) future version:
- Improve the potentiometer (Alps RK27?)
- Remove the UV meters (too small to add any value)
- Replace the platsic volume know with an aluminium one

See above link for my detailed review.
 
In summary: The A100 is to amps what the D100 is to DACs. Very neutral, accurate, and transparent. It's an excellent value for the price. I docked it a star in the "Design" section because it omits balanced ins/outs, which seems odd given the D100 does balanced.

If you want an ideal ss amp, this is the one you need, best bang for the buck.
It is a quality building and revealing sound.
