I think they goofed, when the player EQ says on it is actually off and verse versa. Try it, you can only change the settings when it says off and the sound is EQed. I used to hear the volume going louder when I was turning it off (the real off).

Yeah, their logic is a bit flawed, but think of this:
The button tells you what is does, not the current status.
So when the EQ is off (all greyed out), you have the "On" button to turn it on. When it's actually on, you have an "Off" button to turn it off again. wink.gif

Due so several requests by owners, iBasso changed the names on the EQ. Now the names are for the requested action, for example if it says "On" that means touch the menu bar to turn the EQ on. When you see "Off", that means when you touch the bar, it will turn EQ off. No matter which way it is labelled, it would be confusing until one understands the rationale. Maybe instead of On and Off, they could just label it "EQ" and have it orange for On and dark for Off.

I see now, thanks for the heads up, makes sense.

 

In that case I prefer EQ ON but sliders set to 0, I find the sound to be more realistic, less edgy, less sibilant and harsh, instead it gets more smooth, vocals sound better to me, texture and decay of instruments and bass is better, just imo.

Thanks, that would explain it but gotta say it was initially confusing.

How about the pico slim portable amp?

Its thinness is highly appealing to me.

 

 

Is it any different than the Pico Power in terms of SQ?

The Power has better sound due to a larger voltage swing thanks to its dual 9 volts batteries.  It is more versatile and suitable for driving lower to higher impedance phones.  The Pico Slim is also very good but it is designed toward CIEMs.  The Pico Slim has digital volume control while the Power uses a convention pot.

The AD797 would be operating well below its optimum supply voltage. In some circuits, I have found that the AD797 will remain silent when used below its recommended supply voltage. The AD797 tends towards a bassy and thick sound, not one that I would by any means call neutral. IMO, changing the LPF opamp has minimal effect on SQ, much less than the DAC chip itself. The AD8620 also calls for a +/- 5v minimum supply voltage for proper operation.

 

Hiflight are you sure the DX50 uses a 4.7v single sided supply? I have info pointing to the DX50 using 8.8v single sided supply, and it makes more sense seeing as ibasso claim 9v voltage swing. This means a lot of op amps may be usable in the DX50, like the 797 and 8620.

With a single 4.7 lithium cell, I don't see how there can be a +/- voltage swing without using a floating ground or an 8.8v single-sided supply without a voltage doubler circuit, but having not taken my DX50 apart to do a circuit analysis, I can't be positive.

As I am very pleased with both the output power and SQ of the DX50, I will not be attempting any mods to the circuit board. Without sockets, removing wave-soldered opamps is risky and nearly impossible to try multiple different combinations without damage to the traces. I am trusting iBasso on this one.

The LO sounds wonderful, so the amp section must be to blame for what I'm hearing. Extreme hiss with all IEMs and torrents of bass are not what the DX50 should be putting out.

Anyone?

Could be your DX 50 is defect

DX50s are slightly light on the bass.

Its true with default settings, but there are ways to increase bass and reduce the treble, like turning eq on but leaving values at 0.

Hey guys haven't followed the thread for over 1000 posts so can anyone update me on what I should update the OP?
