If anyone hasn’t jumped yet - Amazon.co.uk has a prime day deal, down to £71.20.

I don't know if it's part of Prime Day, but the US site has a $10 off coupon (checkbox below the price)

One thing that wasn't mentioned is that this device not only is great for listening to music but can also do:

- get your car BT enabled (if you car only has AUX, like my now sold BMW 6 series)
- makes all your cabled IEMs "wireless" as to not need the phone connected to it (great for the gym)
- makes all you wired headphones a "headset" with a great microphone in it... I use it all the time for conference calls to have my hands free
- flexibility to wear: I can put my CIEMs in and run them down my spine under my shirt, clip the ES100 on the back of my jeans and have incredible freedom of movement without a cable dangling in front of me - great for so many activities. Like musicians do on stage and TV presenters etc. The "chin slider" is a perfect "neck slider" and also eliminates microphonics of the cable.

Cheers.

Good tip about wearing the cable down the spine!

Dual AK4375a DACs works for bluetooth from the image below, although I'm not sure how they works exactly.

Usually a DAC has a lot of "channels" it can use and bundle. Depending on the DAC chip (some are even multi core) you basically have already a few channels bundled for left and right. However, if you use two DACs you use one for left and one for right exclusively instead of letting the day handle both channels in one DAC/core. That way SNR and whatnot is improved as the DAC can use all its "channels" on just one side of the stereo spectrum.

See this from 2001: http://www.ti.com/sc/docs/news/2001/01038.htm
and here to search of todays offerings from TI (Burr Brown): http://www.ti.com/audio-ic/converters/dac/overview.html

So in short: for stereo you need 2 channels - some DACs have 8 channels, so you can combine these and enhance the performance to a set of 2x4 if using stereo. Or you can let one DAC with 8 channels do only one channel = 8x1 and have dual DAC setup.In my opinion (!!) a dual DAC setup only makes real sense when using balanced amp setup and output. Since the ES100 uses the AKM4375A DAC with a build in/combo with an amp, using one chip per channel also improves the power output as the whole power is available per channel and doesn't have to be split. One of the reasons the ES100 sounds so good and can drive so many cans. It has quite a lot of power.

"our" DAC has 2 channels and is used in a 2x2 setup. Here is the spec sheet: https://www.akm.com/akm/en/file/datasheet/AK4375AECB.pdf and the promo page: https://www.akm.com/akm/en/product/datasheet1/?partno=AK4375AECB


Cheers.

Thank you for your detailed explanation.
It helps me a lot understad our DACs.

Officially joined the ES100 bandwagon.

Also bought this 2.5mm balanced cable for my Pinnacle P1 and the Fiio FH5 (on the way)

Really hope it's gonna work well https://www.ebay.com/itm/MMCX-Silve...Cable-3-5mm-Audio-2-5mm-Balanced/262966678773

Really didn't expect to love this little bad boy the way I do, but the EarStudio has become one of my favorite gadgets of all time. The equalizer especially seems to pull back a thick curtain between my iPhone and my SE846, and for the first time I really feel like my headphones are truly worth their money. Awesome piece of tech, and I'm continuously impressed by the app and firmware updates - example: maybe it was the plan all along to enable users to name their equalizer settings, but to me it feels like I read about the suggestion a couple of weeks ago and boom, here we are - name-your-own-settings app update. That's how you keep customers happy.

For an updated version I'd really love to see the following:

• Better buttons. They all feel a bit flimsy, so I'd really love something with a bit more build quality.
• USB-C charging would be cool.
• Not kidding: branding! EarStudio is such a cool name. Put it on your device, folks!
• Perhaps color options? I'd love a white EarStudio.

I need too a MMCX balanced cable, but shorter (60 cm) ... Anyone knows one that don't break the bank?

I would like one as well. Otherwise I'll get the Fiio regular 3.5 mm.

The original Uncommon cable bundled with kickstarter was perfect, but I think is not available out of japan

If you are in the US and need a custom cable talk to @alpha421 (who also has posted in this thread), he runs Triton Audio cables. Fantastic cables. He built my Triton8 MMCX, Copper Amiron Home and Silver Meze 99C cables.

If shipping to Italy doesn’t cost more than the cable i’m Sold!

I don't see an option for shorter than 1.2m.
