The bug fix was to make the pre-amp slider represent the selected forced reduction. I must still continue to compensate for this pointless forced reduction in pre-amp functionality. This is a great product, but the cross feed implementation should have been the wake-up call, it doesn't work...

Yeah sorry, I came across as little arrogant there, I just really love this device and I'm a bit frustrated that I have been listening to it, posting about it and surprised now to find my EQ settings were out the whole time. At the very start of this whole thread, @wslee talked about the need...

Direct Memory Access - yeah I remember that. For this device, I always open Powershell inside the windows folder and run the fw batch file, just intuitive for me being a Linux geek.

I was unable to get the app to recognise my fw 1.41 revision device just then, the device turned on and worked, but no app control. I tried removing the device from the app list, but it would not connect to the mac address of this device. I was forced to revert to 1.32 to get it working again...

Yes, that will help you, but be careful of the EQ pre-sets and volume until the bug is fixed.

There is a major bug in the pre-amp section of EQ in this firmware. I'm sure they are working on a fix... is the EQ on when you experience the drop in volume?

The pre-amp settings Is really buggy, I can't even describe accurately what's going wrong. Please fix, or hire me and I'll come to South Korea or wherever you are and fix - I just want this thing to stay awesome.

I suggest if a real Auto Gain Protector can't be programmed, simply use the inverse of the highest value in the EQ bands as the pre-amp protector and show it changing the pre-amp value so the user is not confused - a switch that when on, automatically changes the pre-amp slider as you change the...

There does seem to be something odd with the EQ pre-amp setting, there is a bug that when you apply a pre-set, it recorded the pre-amp setting in the pre-set, but doesn't apply it properly. If I have a pre-amp boost of 1.9 set for a particular EQ pre-set, then it looks like it applies, but...

Well, it's just that there are 2 stages, let's say stage 1 is where there is the signal coming from your phone to the Bluetooth output and stage 2 is where the signal is inside the ES100 just prior to the EQ before the final result is sent to the DAC/AMP combo. Essentially, for best results...

Another good case for both headphones and ES100: https://www.brainwavzaudio.com/products/earphone-case

I've been under the assumption that the EQ section had no hidden pre-amp, now since the new firmware, I know there is -6dB pre-pre-amp applied as well as your own EQ pre-amp, I have adjusted accordingly, you simply need to make sure any given EQ frequency band plus the current EQ pre-amp value...

I agree with much of this, especially point 7 - this is what I was expecting from an automatic gain limiter, needs to analyse the source signal in real-time comparing to the output from the preamp and eq and reduce the volume instantly to prevent clipping, restoring the requested set volume upon...

OK, so after my rather assertive post about AptX HD and the new 1.40 firmware experiencing dropouts, @wslee actually let me try a version 1.41 bugfix for this straight away... Yep, you did it Radsone, it's been playing for a solid 10 minutes now with AptX HD without any skipping. I realise...

First, when we get LDAC, we get a rather BS diagram that's supposed to demonstrate just how much more brilliant it is than the other codecs, despite using a single sine wave - standard practice for a DSP application, but completely useless for information compression and reveals only how the...
