Good
Things I like about this amp: Doesn’t get too hot, only warm after leaving it on all night. Build quality feels solid. From balanced output, sound quality is very detailed and neutral. Things I didn’t like about this amp: It’s kind of strange, maybe only has to do with the impedance on my headphones, which are the HD800, the listenable volume is only between 3 to 5 o’clock on the volume knob. Below 3 o’clock, volume is too low.

Yes, I tried both low and high gain. It’s better on high gain, but not by much. I’m ok with it because at about 3 o’clock in the volume position it sounds loud enough and at 5 o’clock it’s too loud, and I’m able to find the right listening volume within 3 and 5 o’clock.

The volume control on this amp is not like other amps where you aim for around 12 o’clock, this is meant to be used throughout the entire range of the pot. It also isn’t linear so the further round it gets turned the greater the incremental power output comes for the same amount of movement, takes some getting used to after other amps. 3 to 5 is putting out some considerable power, goi g further will probably make your ears thrum/bleed😁. Also the hi gain is only 11db it should be at least say 16 or 20db, if you have a dac with higher than the standard 4v output or has a variable mode that I creases voltage then this will in effect add additional gain

Believe the hype on this unit.
Spent many months looking for something fun and not clinical to listen to on my Celestee's and LCD c2's. Had been using the headphone out in my Hilo Lynx which is a very flat DA and wanted something more rounded and full. The singxer is that for me. Robust sounding, tight bass and a just an overall more musically pleasing presentation of the material. The hi and low z switches are great too. Hi Z definitely smoothes out the transients and offers a slightly more mellow experience. I think it's a nice bonus. I don't mind the gain switches on the bottom I have kept in low gain and haven't had to run it past 11 o'clock with my headphones. I looked at the rebel amp as well but really needed a balanced connection here so for me this is the best option under $1,000 I had found.

Excellent amplifier
Excellent amplifier ! I am using the SA-1 along with SDA-6 DAC. Pairing with Beyerdynamic T1 .3 headphones. Using the low gain setting since the headphones are 32ohm. Very musical, smooth and detailed amplifier. Compared to Violectric V200 the SA-1 is more detailed and musical. Bass control and soundstage width is better on the V200 but the SA-1 is not far behind. Excellent build quality. This is serious stuff. Make sure you use the balanced jack to get the best out of the SA-1. The single-ended connexion provides a darker sound and soundstage is reduced. With a balanced input and balanced headphones cable, the sound is more neutral and detailed plus the soundstage is bigger. Very impressive. Highly recommended and great value !

Outstanding sound quality
Compared to the Topping A90, the Singxer SA-1 is better-sounding. I like the A90, but it can exhibit just a bit of a high-frequency edge with classical music. With the SA-1, I'm extremely happy with the sound quality, which is warm, inviting, and exceptional for the price of this unit. Sound is especially great with balanced output. I appreciate the inclusion of a 4.4mm balanced output, and a high-low impedance switch. For my headphones, Low-Z is the correct setting. In pre-amp mode, there is no choice for fixed output. The volume knob controls the level. My only complaint is that the high-low gain switches are underneath the unit. To change the gain, you must power off the amp, and change all four switches beneath the unit. This is a minor inconvenience. At low-gain, this amp has plenty of power for any of my headphones, including a Meze Empyrean and Dan Clark Ether 2.

The old K240 is very good. It is resolving and has a very balanced FR. It is not so comfortable because it has fairly thin vinyl pads that will go flat over time (old 80's technology). I don't know how the newer versions stack up to the old. The new ones have a detachable cable, the old one does not. I have not heard the new ones so I don't know how they sound and what the differences are. The new ones are very cheap in price compared to when I bought them. They were over $200 back in the late 80s (which is more like $400 in today's dollars)
How does it play with tubes?

Very clean and detailed with my HD600 and balanced cable. Seems to be a very good value.
