You realize that DAC in K5 Pro is on similar level to middle-class motherboard?

Another thing. I don't understand why people has so bad opinions on V2. As far as I know only output impedance is worse (around 10ohms). So if you really have low impedance headphones it may not be for you. On the other hand if you plan to buy some more expensive headphones M500 makes sense. Buying $400 dac/Amp just for one $200 headphones is an overkill imo.

fist thank you for your time !
i was buy 599 3years a go for 250$ i know have low impedance headphone but i wanna some day upgrade it and 0 ohm output is very bad for me !
now im looking m500 for now to see what happen !!!
why peoples are bad with k5 pro this is very nice amp , i dont know why people not like it ??

A good dac/amp is equally important as good headphones. I was running my Sennheiser 58x (150 USD) with my SMSL M500 (400USD) and it made total sense. It sounded better than on the DX3 Pro (220 USD). There is no rule that says your dac/amp cannot cost more than your headphones. It's about getting good signal quality to your headphones. Even my TIN T2 (50USD) improved on the SMSL M500 vs the DX3 Pro.
If you don't use the white in ears that came with an iphone 6 you will hear a difference if you use a good dac/amp even on much cheaper headphones.
People here don't "have a problem" with the DX3 Pro. It's just a fact that the V2 has a badly implemented headphone output. If it would have been like this on the V1 it would have never been recommended by Amir, let alone become his daily driver for use with his IEMs.

As I can agree that M500 is clearly better device than DX3 Pro, I cannot agree with some other claims. Don't not why M500 sounded better for you. It has similar power, maybe little less than DX3 pro with 150ohm load. Output impedance of 10ohm is to low to make a difference with HD58x. Maybe it's just placebo maybe your DX3 was broken - who knows. Low output impedance is much more important with portable devices in my opinion...

About Amir's recommendation - DX7s got recommendation (10ohm OI), DX7pro got recommendation (expensive, 6.2ohm OI). DX3 Pro V2 as affordable dac/Amp combo (around $160 on Drop) would probably get it also...

Amir has any IEMs who would have guessed? ;-)

Good thing is you like you M500, that's most important and that what counts.

I have the Dx3 pro and the M500, and I can't hear any difference between them...fwiw.

I even had 2 different units of DX3 Pro and the P50 LPS.
On my IEMs: DX3 Pro had no bass, M500 totally fine.
On my 58x: DX3 Pro had bass, but didnt extend as low as M500. Voice was presented in front of music. M500 presented voice more as part of the music with fuller bass.

There was clearly and audible difference.

DX3 has 10 OHM output impedance, so of course it can affect IEMs. It's not the DAC you are hearing... it's the output circuit.

If you read my statement a few posts above that is exactly what I said. V2 headphone out sucks.

I only heard V1 which sounded good, would be sad for V2 to be that bad. I hope it is still acceptable with >= 80ohm headphones..
