plus of course a big saving if it is at least equal to the Yulong a18

was actually thinking those 2 would be competitors. But I suspect the SA31 would be more coloured, where the A18 is more analogue. (Ofcourse I have heard neither.)

I have a question for owners: can you select to which headphone out sound is outputted or are both outputs active at the same time?

Both at the same time.

Thanks for the reply Fau. I was hoping to have both headphones plugged in at the same time and then switch to whichever I would like to listen with. Did you get yours with dual 6.3mm outputs?

No. Almost all my phones are 4-pin XLR terminated.

I am 99 percent sure that the SA31 is the amp for me and my HE500's.
It obviously has more than enough power,and you have have found it to sound good
Does it have any background noise? How hot does it run. How is the service now? Some time ago,one member complained about delays in shipping.
Thanks in advance

No background noise. It runs warm, I'm guessing - around 40°C in 25°C room. Do not know what to answer about service - I have always had good experience in dealing with KingWa & his pals at A-GD.

 

BTW, my SA-31 has settled. It gained "blackness" comparable to Roc, but it has much "richer" sound than Roc. I've also re-evaluated "warm sound 1" and "warm sound 2" settings - it "bolds" the sound over whole frequency range and so it adds heavier stomp to lower notes too. No detail masking as I reported first time. "Warm sound 2" is perhaps too much, but "warm sound 1" is just about right for me. I might even give up on my modification plans for it... wink.gif not sure that Mundorfs can add anything more to the sound.

replace "with" with "wish" and it should be clear

Well, yes... digital up/down buttons are no match to knob turning intuitivity. It takes some time to get used to buttons.

 

But beside that - it performs flawlessly: it is not in signal path, channel imbalance is non-existent (useful in late night low level listening), has enough steps and gain settings are well chosen (+10dB/+0dB). I've opted for additional volume board (+5dB/-5dB), but had not have reason or urge to swap it in yet.

 

OtOH, you can get remote which sets you back for additional $50 which is,perhaps, a bit steep compared to whole unit cost... it is "indestructible" (aluminum) but rough on some edges (DIY fixable)... it has no repeat feature for volume up/down functions which KingWa explained as intentional - so that unit does not mix-up remote commands; not so sure this was not doable but funny thing is you can change volume faster with fast repeated presses on remote control than with holding volume up or down button on SA-31... it has no mute button (workaround: swap to "empty" input channel)... it has no standby (on/off) button... and I miss the most a button to dim or turn off the display (yes... again lazy late night listening).

 

Knowing all this now - I would order remote again... it is priceless in certain lazy lay back moments.wink.gif
