Wow nice, we now have Q factor adjustment in the EQ. Is this a step towards a fully parametric EQ? It would be very nice to have per-band adjustments for frequency, gain, and Q. @wslee, if you're listening... :ksc75smile:

An earlier post sharing Radsone's roadmap included the addition of a 10 band PEQ, which should give us that ability (and more). I pretty excited about this myself!

AAAAAAAAAAAAAAAAAAAH!! Gotta give it to Radsone for making what is already a killer device even better! With this I'll be able to notch out peaks in some of my IEMs... ahemMD+ahem

What's wrong with 48kHz?

God dammit Sony. Guess there's always firmware v1.2.2.

The checkbox is disabled in the checked position. Tapping it does nothing. The ? button only explains how codec selection works, and not any specifics about the different codecs. Guess we'll have to wait for @wslee's response.

The app on Android shows LDAC as mandatory. Tapping the checkbox does nothing. Don't know about iOS.

Any reason why LDAC is mandatory? I would like to use crossfeed sometimes, but that's only available on other codecs. I know I can disable LDAC on my phone through developer options, but would prefer to keep these tweaks in one place if possible. If Sony mandates that LDAC must be used if...

The explanations in the app are pretty much just fluff. The slow roll-off filters cause aliasing, which means additional tones that aren't supposed to be there. You don't want to use either of the slow roll-off filters for maximum fidelity. The short delay filters are minimum phase filters...

Huh, there are still people correlating price with performance? :thinking:

MD+ upper mids match DF compensation -- this is neutral according to the DF reference. To my ears, the MD+ has a hot region right around 7-8kHz, depending on the ear tips used. Narrower bores push the peak up, and deep insertion (3-flange) flattens the peak somewhat. Upper treble >10kHz is...

WS, any news on the possibility of adding crossfeed?

I use a Radsone EarStudio with mine.

I use a Google Pixel with Android 8.1. Thank you for the detailed explanation. Personally, I set it at 1x as I hear no benefit from oversampling, but it's nice that the option is there.

I have the same issue on Android, where the battery level shown in the OS isn't the same as the one shown in the app. I believe the issues on iOS and Android share a root cause, so a fix for one should fix the other. WS, correct me if I'm wrong. I think the oversampling option performs a...

Thank you for your thorough investigation. I suspected it had to do with the filter setting and I was about to take some measurements myself, but you beat me to it. I've had mine on the symmetric sharp roll-off filter to preserve linear phase. In my opinion, offering the slow roll-off filters...

They do live up to the hype. If you want neutral plus some bass slam, the MD+ is the IEM for you.

Try Spiral Dots, they're thicker than the stock tips and offer better isolation.

WS, do you guys have any plans to fix the issues I described in this post?

It's good that you asked, since the MD+ has a fairly wide nozzle.

I've had my ES100 since Friday. This is pretty much everything I've wanted in a source device. I'm really loving the BT/USB dual function. Some feedback: On Android, the DAC filter selection UI is buggy. It'll sometimes show two modes selected at the same time when I try switching modes. Also...

As a fellow former owner of the Phonak Audeo, yes, yes, YES. The MD+ is like an Audeo with gray filters and more sub. Except there are no filters to change. :D Driving them from the S7 will likely darken the sound, adding more bass below ~200Hz. This depends on the output impedance of the S7...

My own experience with the BTR1 was that it put out a ton of noise. I'm hoping that the ES100 will be much quieter.

Thank you for the explanation! It's a bummer that AKM quoted you a spec that is poorer than the actual performance. Glad you measured it! Indeed I'm planning to use the ES100 to drive multi-BA IEMs, which are very sensitive to source impedance. The Massdrop Plus IEM gets bassy and loose with...

Right, I remember seeing that in the docs on the EarStudio page. Thanks for publishing those, by the way, super interesting stuff! I'm trying to learn as much as I can about the ES100 and the DAC inside it, and came across your kickstarter comment where you (Radsone) wrote that the AK4375a has...
