I think most smartphones don't let you use them as a DAC though... which makes testing them impossible right?I have done a couple before. I just don't have good access to more.

I can run some tests but not all.I think most smartphones don't let you use them as a DAC though... which makes testing them impossible right?
You can hear those harmonics below 100dB?FR response bug aside, those are pretty high levels of upper odd harmonic components making up the THD. I'll stay away.
5th, 7th, 9th harmonics are very unmusical and should be 10 to 30 db lower than they are. It's the culmination of their summation to the strong 3rd that makes me say, I'll stay away.You can hear those harmonics below 100dB?
This is what I'm most concerned about.That would be one explanation of what is going on. What is strange is that we see the same thing in Marantz so I am thinking it has something to do with programming the AKM DAC.
The iBasso had to be returned to Amazon due to deadline for the return. So I can't do any more testing on it.Are you able to test this here?
He had bought it from Amazon and drop shipped it to me. So he just asked for return on Amazon and I shipped it back for Amazon. That way we saved on the shipping cost of me sending to him.Did you return it? Or ship it back to original owner to return?
Absolutely.He had bought it from Amazon and drop shipped it to me. So he just asked for return on Amazon and I shipped it back for Amazon. That way we saved on the shipping cost of me sending to him.
So if you like to do the same, it works. We just have to be mindful of the time it takes me to test it.
Absolutely.
I planned to get the hiby r6. I might also order an Ibasso for testing since if it works and it's cheaper than the r6 pro (what I actually want but so expensive) then I'll finally know if android works with my apps! Thanks a lot hope to be in contact soon as funds permit!
It would be the pro version yes sorry about the confusion. Hiby promised a special for people who signed up and then never delivered.Is it the original R6 or the Pro? The Original R6 has a very high output impedance (> 10Ohms) which many argue defeats the main use of the device as portable player. I am looking at the pro version as Hiby claims they designed it to have a < 1 Ohm OI. But I prefer to see independent measurements before I decide to get one.
Hi there. In this case we don't need more points because the roll off starts pretty early. But yes, will do.Hi @amirm
For the frequency response graph, could you sweep it slower and add more frequency steps?
I think I have seen this behavior on AP2700 where I could get a roll off in the high frequency if used 5 seconds sweep and less than 100 steps.
If you get the chance to measure the Ibasso dx120 again

Yeh but that requires someone less lazy than me....I think results like these suggest frequency response should always be measured, just in case there's something unexpected going on as is the case here.
