Maybe someone can send in a modded version for Amir to test (with and without the DC bypass mod).

do you think what I perceive as improvements will be detected on his graphs?

Maybe? One way to find out.

perhaps my perceived improvement may be greatly due to the placebo effect.Sigh, just what we needed, perpetuating magic tricks

Well, you didn't try the Sabaj amp did you? For me I'm glad I got my money back, there was 0 sound difference and the Sabaj amp has magnitudes more headroom than the Sinxer, if I ever need it.
But yes the SA-1 seems nice with a balanced DAC + from its XLR output, but that's not super versatile though is it
I prefer amps that work just as good on all inputs and all outputs.Roland68

Actually there is no difference between balanced and unbalanced inputs on the SA-1. The unbalanced input is balanced before the potentiometer and amplified to the same level as the balanced input.Well, you didn't try the Sabaj amp did you?

I use the SA-1 with both inputs, all headphone outputs and as a preamp.
I haven't noticed any limitations yet.

I've just acquired an SA-1 and using it as a preamp for my stereo amplifier. Chain is Topping E50 -> SA-1 -> Amp. I am getting a pop from the speakers when going from off to pre switch. Is the Pre setting going through some active part of the amp causing this? I noticed the SA-1 gets warm in just Pre mode as well. I was hoping the Pre function would be passive.

Sorry, but the preamp section of the SA-1 is of course active.
The cracking is probably caused by the relays of the outputs.
Are the devices connected symmetrically or via cinch?
Did you connect the SA-1 to an integrated amplifier or a power amp?

This is an active amplifier so there are no passive functions, it always goes through the amp.
Found the issue, cheap XLR cables.

One of the reasons I make my own cables...

Hi guys hope i haven't ask this before just have a issue with my Amp the SP200, I have the Hifiman Ananda and Dac SMSL VMV D1SE with the SP200 which the XLR inputs are defective but looking at a different amp looking at this Singxer-SA1 or Jotunheim 2. What would you think be a more bass out of my Anandas and not as harsh highs? or dry and still sound.

thanks. I am really looking to tame the Ananda in the highs and make them more bass and warmth more musical. I listen to Rap, Hip-Hop reggae, and r&b. And Spanish music. I like vocals to shine too in females or in males. Just want to make sure I pick right amp. As I'm not sure if I over did it in the Dac department with the D1SE.

If you are looking for a balanced headphone amp then I think the SA-1 is a good choice. For me it reproduces music on my AKG K812 just as well as my Violectric V100. And the K812 is known to be a bit bitchy (in reality just honest) in the treble range and it also reproduces the bass rather neutrally.

I bought the Audeze LCD-5 as it matched my Singxter perfectly. It is now going to be burned in as some dudes recomennded. Audeze provided gloves but I am really expected to wear them every time I listen to the phones? I run them with the gain set to low.

Audeze only wants you to wear them when you touch your LCD-5.
Especially if you have already creamed your hands that day

I know this is a technical forum but I love cute things and what I suggest will improve the wife acceptance factor of your gear as I am a stylish fashion lady myself.
Well, Is there any way to make this amp more beautiful by replacing its volume knob with a big red one? Where can I buy volume knobs shat fit this box? It will look soo elegant with one and more suitable for a feminine lady.

You won't find much in this size, maybe silver or gold.I know this is a technical forum but I love cute things and what I suggest will improve the wife acceptance factor of your gear as I am a stylish fashion lady myself.

Diameter 32mm x 13mm (12-15mm is also possible), bore is 6.1mm (up to 6.4mm would be ok), attachment to the axle with a grub screw.
Ask one of the Aliexpress sellers if the "Aluminum Potentiometer Knob 32 x 13" is also available in red, or if they can have it anodized for you.
Alternatively, have your aluminum potentiometer knob anodized, have a new knob turned and anodized at a lathe shop near you, or have your knob painted red with metalflake (airbrush in car or motorcycle painting / effect paintwork).
