Thanks for the pics, BTW, on your website, the weight is wrong (205g) for 320, maybe that's the weight with card plug out?

If you could check out the PEQ and maybe explain what Filters are/how to use Filters in it (manual doesn't tell you how to input frequencies, Q factor and gain. I couldn't understand the point of the Filters. It looked to me like they were quite inflexible). Sure, powerAmp is a natural alternative (100% easy to use) but why even include an on board PEQ if it's too complicated to comprehend immediately?

Hey, so yeah, PEQ can be really confusing. The 3 filters you're going to want to use are typically Low Shelf, High Shelf, and Peaking.
Each filter has a frequency (Fc), Gain, and Q.
The Frequency is the point where the filter starts, the Gain is the magnitude of the change, and the Q is the shape of the filter.
Gain can be positive or negative – positive gain will raise the volume of the frequencies in the filter, negative gain will reduce it.

For the Low shelf filter, starting with the Frequency where the filter is set, you'll get a lift into the shelf. A higher Q makes a faster lift and a bigger shelf. A lower Q makes the lift more gradual into the shelf.

So in the first picture I have a Low Shelf Filter starting at 100Hz, with a gain of 4 and Q of 1.

The High Shelf basically just flips the Low Shelf. Rather than a boost to frequencies below your Fc setting, you get a boost to frequencies above it.

The Peaking Filter operates more like a traditional 8-band EQ sort of thing. You set the frequency, Gain is the level of boost/cut, and Q determines how wide/narrow it is. High Q is narrow, low Q is wide.

In the second picture I have a Peaking filter at 1000Hz (1kHz), with -6dB Gain and a Q of 1.

So if you combine the two, you have a sub bass boost and a mid cut.

Hopefully that makes at least a little sense.

Hmm... that's the spec we got from iBasso, and I just dropped it on the scale at our office, and I got 5.8 ounces/164.5 grams for just the player.
There's no removable amp cards or anything with this one.

BTW, I was talking about the weight of DX320, not DX170. The iBasso website listed it as 310g.

Ah. Thanks. Good call – updating now!

I really appreciate the pictures, this really does help with what I am trying to figure out.

Do you think its pocketable enough to be used for gym purposes? I am currently using the first hiby r3.

while the M11 Plus has a faster processor and more RAM, the thing is a beast. Its huge, thick and heavy, and I'm just looking for something smaller, lighter, thinner. Plus with Android 11 rather than Android 10, the DX170 is slightly more future proof for use with Apps imo.

And, M11 plus has higher output impedance of BAL PO which going to affect tonality of some multi-driver IEMs. Just saying.

Will be interesting to see comparisons between the DX170 and the FiiO M11s, if it is released this month as FiiO was suggesting.

please post some impressions of the two compared to each other after you have spent some time with the DX170. both of these DAPs seem pretty appealing. thanks.

Yeah, thanks for that explanation. Since I would mostly try and emulate the tuning of one IEM on another, I think I would only use Peaking filters. So there are six filters. That means I can only make six changes to the EQ, right? I can't make two or more changes per filter? Instead I switch each filter to on and combine them that way? Sometimes I need 10 settings to get the graph close to another IEM. I'm not sure if there are limits to the number of settings you can use in powerAmp. Anyway, at least I can start with this and experiment. The DX170 is roughly €370 in the European store so it's quite a 'bargain'. I've used both DX90 and DX120 before and have had no complaints other than a battery drain problem with the DX120. I returned the player for service and they sent me a new one (UK dealer).

Right, so each filter = 1 change, so you get 6 changes, but what makes it more powerful than it seems is the Q factor, which enables you to potentially cover 2-3 bands from a graphic EQ in one filter. The High/Low shelf can also provide a broad adjustment which you then tweak with a Peaking filter.

Of course, there's also a 10-band graphic EQ which might be easier for some adjustments...

Dx170 has BT receiver and transmitter function?
I don' t know much about dap in general.

Removing this as the information therein was incorrect.

I does have a Bluetooth transmitter function to output to a streamer or wireless headphones. It also, in theory, can receive Bluetooth, and I've tested pairing it to other devices, but there isn't any Bluetooth DAC or similar function that I've been able to figure out. So, for example, pairing it to my laptop works, but doesn't have any function that I can find. There isn't anything documented in the manual other than basic pairing either.

If you go to the Mango player settings where there is usb dac, the following line is Bluetooth DAC mode.

lol. Not sure how I missed this:
