It arrived last Friday.
I made some comments on

Well, first impression is good. I think sound quality is on par (may be better) with A90. It has better bass control when I am using HD650.

Have you compared the high gain power between A90 and SA-1?

If you have HD660S try it, it may sound a lot better than iDSD BL ( as per your signature

I'm using HE6se, the 660S sounds great on the SA-1 as well. I am saying though, RCA in is not as good as BAL (I'm using Freya so the RCA/BAL is of equal SQ) and SE out on the amp is significantly underpowered compared to BAL. That said, this is an amp made to be run fully balanced. The SE is there for convenience. Bal in-out this amp is much preferred in my books.

Not welcomed is the warranty void if removed sticker on bottom screw holding the top lid.

I just crossed the DC jumpers inside the unit. Yeah, wow. It sounds much better.. it's a huge leap over the Jot2 at this point. I'm curious what the risk is using those jumpers.

Can you take picture for the jumper, I want to do it but want to make sure I don't cross things.

Alright so, this puts the amp into DC couple mode. You have to ensure your dac/pre don't leak DC. Using a meter I measured my Freya S, flat 0 powered on with no music playing. Safe.

I currently have the Singxer SDA-6 Advanced version DAC and I love it. Very musical. I currently use it with the Violectric V100 amp along with Beyerdynamic T1.3 headphones. I have the SA-1 on order that should arrive soon. The SDA-6 DAC is my favorite so far over the Gustard A-18, Teac UD-505 and Violectric USB 24\192 card that I also own.

Do yourself a favor, order this knob. Perfect fit. Stock knob is terrible.

I just placed an order for the sa-1 on drop.
Looking forward to giving this a go.
Intention is for use with Utopia, Stellia and GS3000e as my other amps have too much gain/power for these sensitive headphones.

What DAC do you have ? and do you have the Susvara to try it on SA-1 !

I have the rockna wavelight. But will probably pair this with an okto dac8 stereo. Yes I have susvara. Will try the susvara with this amp and see how it goes.

FYI this amp has high gain mode, but the switch on the bottom and there are 4 switches which you need to toggle them all to enable H Gain

I received my Singxer SA-1 today from Drop.com. I'm using it with a Chord Qutest DAC and Meze Empyrean headphone. This is my first amp with an impedance switch (Hi-Z or Low-Z). Can anyone advise me on how to set this? The Empyrean's impedance is 32 ohms. I found the User Handbook for download from the Singxer website. According to the manual, "The low-impedance output impedance is 1.4 ohms (balanced) and 0.7 ohms (single-ended); the high-impedance output impedance is 11.4 ohms (balanced) and 10.7 ohms (single-ended)."

Low-z for all low impedance up to 90+ohm

More than 90ohm you may try High-z and see if the bass still tight or get back to Low-z
