Singxer SA-1 / Balanced Amplifier Fully Discrete Class A - beyond THX 888 ?!

its amazing, airy, soundstage is great with class a amp. im paired it with d90se and dont forget turn on setting 0 db from 4v to 5v.

The Singxer is only class A in low gain mode if you don't listen very loud. I think it was like 0.5 watt before it changes to A/B.

But i still love the Singxer.
Using it in high gain mode with high Z and the DC Aeon 2 Noire.

Focal Elegia in high gain as well because I'm to lazy to change it every time 😂

Have been using the SA-1 in low gain mode with the focal Elegia in balanced mode. 1-2pm was Usually more than loud enough.

Today I got the Dan Clark Aeon 2 noire and I'm definitely closer to maximum volume if I want "loud". But that's still In low gain.
Who does the Aeon 2 sound to you compare to Elegia ? is it an upgrade ?

The Class A mode of the SA-1:

In Balanced 16 ohm load: under 500mw;
32 ohm load: under 1000mw;
68 ohm load: under 3000mw;
Load of more than 68 ohm : almost all the power is class A.

Where you got that information from?

Yeah definitely a upgrade.
Even with sheepskin pads and EQ on the Elegia, the aeon 2 noire are "better".
(At least to me).

But if you prefer punchy fast bass and enjoy the "focal" sound they might be more to your liking.

I really enjoy the noire for most music.
But my wife prefers the Elegia

almost took up an offer for a very good deal on this DAC, anyone ever compare it to the SABRE DAC in the Oppo HA-1 (ES9018) considering doing a setup with tubes, the AMP in this thing is magic but I want to see if there are any more resolving smooth DACs around and need to be careful after testing the E90/D90 which I thought was atrocious

Use my 1 day old SA-1 with a Sundara with balanced cable. Can anybody explain what the high and low gain do in terms of sound, and the same for Hi-Z en Low-Z. I'm not so interested in the technical aspects, but more what these settings do for my ears.
What settings would be preferable for the Sundara. Thanx !

Low gain will lower the noise floor. High gain will allow you to turn up volume on inefficient headphones. Since the switches are located on the bottom, power off your amp and just leave them on high gain.
.
Gain switch might change sound. Try it. If you don't hear a difference, then just put it on either one.

Hi hottison. What do you mean by 'lower the noise floor' ? And what are inefficient headphones ? Are the Sundara inefficient ?

When there is a pause in the music or between tracks you might hear hiss or noise. Lowering gain will reduce this. I just leave mine on high all of the time so that I don't have to turn off amp and adjust switches on the bottom.

Inefficient headphones are headphones that require you to turn up the volume knob because they are too quiet compared to other headphones.
