So does anyone else think that aptxHD sounds better than LDAC? Like more lively and more dynamic is the way I'd describe it.

LDAC at 990kbps is better than APTX-HD.
This is especially noticeable in tracks with high quality bass.

That's not what my ears are hearing though.

I've heard implementations of AptX HD and LDAC that were close to transparent. The potential for both to sound "good enough" when compared to uncompressed wired is there.

Are you listening to Hi Res? I don't think aptX HD has the bandwidth for Hires files. I found LDAC can get you closer but it depends on the implementation (doesn't really work as well on my ES100/Samsung S9 for example but ia fantastic on my 5K/V60). I only use aptX HD with my Shure BT2 amd Nad D3045 and.tried aptX Adaptive with my Qudelix 5K and thought it was just ok but prefer LDAC for sure. I actually disabled aptX Adaptive on my Qudelix 5K because it was the only way to force LDAC with the V60. If you're just listening to Spotify or even CD quality then that is a different story of course.

Your ears and brain are different then mine obviously so we may just have different preferences in the end. As long as you like what you hear, that is all that really matters...

Toggling back and forth just using Spotify, aptxHD just sounds better to me. Pixel 4a and ES100/K371

Got it. Spotify maxes out at 320kbps so bandwidth is not an issue for either. I mostly listen to Qobuz. I did find my ES100 did not work well with my S9 over LDAC (could not achieve 990 without stuttering even when right next to each other, although I was able to force 990 with a little more luck with my 5K and S9. V60 and 5K...don't even have to force 990 (i.e. goes to 990 even on Best Effort). Maybe my ES100 was defective but I always blamed the Samsung phone.

I have had the ES100 with the Galaxy S8 and Note 9, both default fault to Best Effort every time you connect. I hear no difference with the 990 so doesn't bother me. I listen to some Hi Res local files and Spotify Premium

Interesting to see some of the posts here, and how LDAC works for them. For me with my Samsung Galaxy S8+, my ES100 pairs well at 990 most days. It's actually always at that number, but it seems to be day to day dependent on whether or not I get stuttering or dropped signal. It seems to be mostly dependent on how far I move away from my phone, while ES100 is still with me. Either way, it doesn't bother me much. As soon as I get back close to my phone, everything locks back in again.

This might be a dumb question but I'll ask anyway.

I am in the process of getting a desktop setup for bookshelf speakers + headphones/earphones.

I'm wondering if it's possible for me to use my ES100 as a USB DAC connected to my PC, and also use it as a DAC for my speakers (by connecting the ES100 to a separate speaker amplifier)? I'm very new so please let me know if my thinking is flawed.

Yes, that setup should be possible. If it’s possible to configure the ES100 for line-level output you can use a normal line-in on the amp and set the volume on the amp.
The other option is to use the volume setting on the ES100 and connect it to a power amp or powered speakers.

You can use it as a preamp and a USB DAC/Amp. I have mine connected as a LDAC bluetooth receiver in my living room feeding a Denon X4300 receiver.

Note, in USB mode, the ES100 is limited to 16/48 I believe.

Anyone use it ( E100 MKll ) in car? How do you set power mode to switch off E100MKll when car ignition is off ( USB power cable is permanently attached).

I dun see any setting in Earstudio App. And do you use preamp or amplication for car mode (3.5mm Aux Jack )?

This thing had improved my car ICE SQ without overhauling my current system👍

Tap the battery indicator om the home screen to get the Power Options menu...I think the third option under Charging Mode is what you are looking for.

Got it👍👌 I'm hearing better on Aptx then Ldac. But Aptx let you adjust crossfeed and DCT.
