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

So far I’ve only run it low gain mostly with my 2021 LCD-X. Are you running on high gain always or switching depending on the impedance of your headphones? Would my LCD-X being a low impedance HP (20 Ohms) benefit sonically (other than more headroom) running in high gain? (I’d rather not do the DC mod for various reasons, especially if the benefits don’t outweigh the risk involved)
I have been switching the gain depending on the headphone impedance. For anything under 60 ohms, I don't hear much difference between low and high gain. But my Verite needs high gain or it sounds "soft" in transients/attack.

I don't know if your LCD X will sound better to you in high gain or not, but it wouldn't hurt to try it and hear for yourself.

I think the jumper mod can degrade the sound quality as the sound pass through it. The quality of the jumpers is important like cables. The best solution bring a speaker cable cut 4 pieces each 15mm and twist it u shape and install it.
wouldnt recommend that approach cause im pretty shure you wont get a good connection on all the jumpers, think youll have more luck with the normal jumpers or you solder some quality wire in :p

Same here.. always worth relooking at your set up again after new purchase..

Swapped a streamer for a pimped celeron NUC fanless with industrial memory. Custom LPS.
I had not used for a year... Spotify premium, all the Audio changes to reduce latency in win 10 and make it audiophile friendly... Headless via phone.. Fidelizer as it's cheap..really good sounding and worth the effort doing up the nuc for headless audio..
Win 10 key was £6.89.

If you have a dedicated windows audio computer.. From pro audio to audiophile tips such as these below...
And other software like HQP ect...

Not done them all yet but from a saved Googling session.... Linux is normally best sounding but can be difficult..well for me..

Last time I turned on a windows machine was 2009. For 5 million $ i would turn on a windows machine again, but otherwise, i am not touching that piece of **** ever again.

Linux or a streamer... Maybe, but i prefer simplicity. I already have a computer, i will use that one i already own.

Shame there's not really any competing Chromecast audio product on the market now - cheap dongle with SPDIF output easily controlled by phone or PC supporting casting.

I'm on high gain all the time. LCD-X to me needs the extra gain, they're more dynamic and low end is massive. Are you using balanced connection? Makes a big difference as well.

Yeah I’m using balanced, I’ll give high gain a go tomorrow. I was listening anywhere from 12:00-2:00 on low, my thought was keeping it the low gain made it less likely to switch to class AB but you’re probably right on needing the extra punch in the low end and I can honestly use the additional headroom at a minimum since I started EQ’ing them.

This how I did it. Pure OCC cable. :p

Cheapest fast delivered UK cable silver plated was 5 metres... I could mod head fi and most of Europe 😉.
This is what forums are about.. helping and best practice. I did think of direct soldering...

Low tweaks for low latency on my NUC celeron and I keep getting more out of the Singxer... It's a hobby that keeps on giving.... Mostly taking from my wallet..but ..
