So you got two opinions now, OPA627 as the best and OPA1641. I haven't tested but from what I know the OPA1641 has better soundstage and is cheaper too

Yes, I have to say the the OPA627 is really awesome and sounds great with my amp. I don't intend to swap it out any time soon::But, I do agree that the OPA1641 is also great. I just had to try the OPA627 given the high reputation it has. I would also try the OPA827 which goes for $10 for each and supposedly rivals the OPA627. smily_headphones1.gif

I'd jump in with some sort of distraction....

 

I tried the ASUS Zenfone 5 (A501CG) recently with the M40x (I personally own HTC Desire 820, it sounds really good)

 

The sound of the ASUS Zenfone 5 was superb. Far, Far better than my HTC Desire 820 (DS). It sounds way more natural and bass and treble extensions are great.

 

What DAC chip and opamp it might be using? It is very good and if someone owns a good DAC/AMP he/she may give a comparison of sound.

 

Intel Atom does not have an inbuilt audio DAC (AFAIK).

If you tried the headphones straight from the phones audio output, maybe it is due the difference in the phones output impedance?
From my own personal listening experience the output impedance has much greater impact on sound than DAC chip or OP amp itself.
This could be found out, if you had a headphone amp and you would put it between the phone audio output and the headphones and listen if they sound much different anymore, but I dont know if you actually had already done it like this?

I have a question about Op-amp replacement. When I compared two schematics, I noticed that ne5534 has three extra signals(COMP, COMP/BAL and BALANCE) than normal signal OP-amp. Can I use any OPA series (like OPA111) to replace ne5534?:bigsmile_face:

 

Thanks everybody.
