? Mine doesn't have that... How can we reasonably compare opinions if they keep changing the design all the time?!

Yes ! You got this new version of PCB. H/L switch is high low gain.

Basic design & sound signature is no change but some option can be choice by customer.

Due to high impedance cans need more gain but low impedance cans need less. So add a feedback control switch on it. Jade can drive low impedance Cans verywell. So I think Denon cans is no problem. I only tested on Grado SR325 , ATH-900TI, AKG-501 & K701, 240DF , Beryer DT880 , SEH HD600/650.

So, what is the factory recommendation for using H/L for particular phone?? For example, how setting should be used on Beyer DT880 (600 ohm), SA5000 and AKG K501??

Thanks a lot.

I just burnin the amp less than a day, so not much impression about it. i will let everyone know about the performance for it.

DT880 & K501 use high is better due to it need more gain. Jade need to burn in at least 100 Hours to have it best performance.

yup, and may we know when do the PCB and the design "finalized"??

BTW, can you also clarify which headphone jack is plate outupt and cathode output.

Your amp PCB is finalized design. Left side jack is cathode output , Right side is plate output.

IEC AC input will be include soon.
