Awesome. Hope you enjoy it as much as I do mine. HUGE bang for buck.

Thanks. I have one issue, the settings reset everytime I disconnect / power off. Is this normal function? The standard settings appear to have crossfeed enabled, and ambient mic noise, but I dont want either applied. And Id like to keep volume max output setting much lower than standard, but it resets everytime. Am I doing this wrong?

Just received. Need to research filter

Something is amiss here. Are you stopping the music, THEN powering off? Disconnecting how and from what? Unplugging headphones? I've had mine along time with no issues.

Good question. I only got to use the ES100 for about an hour lastnight. Today Ill attempt to continue to use as normal and try to narrow down the problem and then if necessary ask for help. Thanks

Still resets crossfeed settings etc everytime I reconnect to use again. Is this normal operation?

No, I don't think so. Can't remember my unit ever loosing its settings... If this is still new / within warranty, I'd try to get a replacement.

No, I bought it used unfortunately.
I guess Ill try the Qudilex next but buy NEW.

Sorry to hear that.
I guess you already tried a complete reset? I’d expect something like that should be possible via the app.
I once had the Qudelix, but liked the ES100 much better soundwise and also from the perspective of physical interface: the buttons are much easier to use on the ES100

Does the ES100 require device drivers or some special configuration to use on a Windows machine 10 as a USB sound card? I don't see it in the Device Manager when I connect it.

It works fine for me without installing device drivers. I just tried it on a Windows 10 laptop where I hadn't plugged it in before. As soon as I plugged in the USB cable, Windows popped up a notification that it was preparing a new device (EarStudio USB DAC). A few moments later another notification that the device was ready to use. It shows up as an output selection on Qobuz, and in the Device Manager.

Has anyone tested USB mode on recent Android phones?

Yes, it works fine on my Vivo via USB (Android 12).

 

[MisterMudd]

Well, after 4 years of moderate use my unit has started to stutter when using Bluetooth. Any suggestions for correction, or just relegate to DAC use via USB?

There is no explicit line out mode. The DAC itself (which is inside the integrated DAC+amp chip) probably can't provide enough power for line out anyway. The Radsone website has a link to an application note about using the ES100 as a preamplifier. In summary, if you connect the ES100 output to a high impedance input (such as a power amplifier), the ES100 will operate like a preamplifier and you only have to set the output to an appropriate level.

what is this "appropriate level" ? it seems to be 0.894v peak to peak maximum for consumer grade speaker amplifier but how do i get exactly this 0.894v voltage out in order to maximize sound quality ? is it -9db on the es100 volume level slider to get 0.896v (as it says 3.2v peak to peak at +2db) ? and should i set the 3.5mm output to 1x current or 2x current ? ( would have been nice to have a "consumer grade line out level" option in the user interface to bypass the volume control on es100 and only control volume on the speaker amplifier, without accidentally raising volume on the es100 over 0.894v which would saturate/clip the speaker amplifier line input) thanks

I think my es100 mk2 just kicked the bucket. I was listening to it while plugged in charging and it shut off by itself. Unplugged it and turned it on and nothing. Plugged it back in now its warm and smells like burnt electronics. Anyone encounter this issue?

try opening it and cut one of the 2 wires to the battery as it may have a short circuit inside the battery, power it using the charging cable. if it is working you just need to buy a new battery ( you can even put a bigger battery inside as he did here :
