  OP Amp: TPA6120A2 for head amp, OPA2134 for "power amp" (no idea what it means, copied from the taobao link above)

 
It means it uses OPA2134 for gain stage, then followed by TPA6120A2 as buffer stage. It also means there is a chance that it might has an output impedance of 10ohm, which is usual for TPA6120A2 to improve stability, unless they did something different with the design.
 
Shanling is an old brand and has done major OEM / ODM job for other well known brands. Hopefully their portable gears are just as good. Their price is certain very attractive.

Thanks I edited the first post. I think Shanling was the OEM of Meier (Corda) amps.
