Matrix M-Stage amp review: simple, cheap, and excellent. - Page 215

Does class-A biasing affect performance with lower impedence headphones ~ 40 ohms?
post #3212 of 4888

The Class A biasing in this situation pertains to the op-amp voltage gain section just before the transistor output buffers. In other words, it helps regardless of what is plugged into the amp.

No.  I doubt you could hear a difference between them.  I've briefly compared it with my E10 and nothing stood out between them.

 

I would stick with the E17.

In plain olde english:

The Op Amp, whether or not it is Class A, does NOT drive the headphones directly.

There is a discrete transistor stage between the Op Amp and the headphone jack.
BTW, the discrete output stage is heavily biased into Class A, irregardless of the Op Amp.

No!
You are very, very wrong!

What next ? All well built DACs sound the same ? tongue.gif (it's was i am tending to think now redface.gif)

 

The Violectric V800 (let's take this one as exemple) mesure better than ODAC (if i am not wrong) but it don't mean in any way that it's audibly better biggrin.gif , but if some one want to loan me a V800 i will gladly accept bigsmile_face.gif and give it a try .

Oh boy. Wellll, I a/b compared my Fiio e17 with my buddies Decco 2 and heard very slight, if not negligible differences. So I don't think there's a need for a >$500 d/a converter. Prove me wrong >=D

It's supposed to be a joke!   tongue.gif    

Frankly it wouldn't surprise me in the least if the ODAC sounded about as good as the E17.biggrin.gif

 

 

I suspect that FiiO may have an "Engineering Staff" to "design" DACs and Amps and stuff for them. And the ODAC has..............?

 

BTW, if anyone wants to send me an Audiolab M-DAC or a Cambridge DAC Magic Plus for "research" purposes, I won't mind.wink_face.gif

Someone should put up a website with a blind test of the E17 and ODAC, and conclude that there were no differences. And announce the E17 the winner because of its extra features and lower cost.

I took it as a joke!  In my opinion, the DACmagic (with upgraded power supply) is roughly equal to the MSII+ in sound, but has enough extra flexibility to warrant the higher price.

I think the E17 is roughly equal to the audinst MX1 with a slightly better dac on the E17, the amps are more of a preference than one being better. All in my opinion of course.

Hey, NP,

Thanks!redface.gif

Personally, I prefer the sound of the M Stage Headphone amp over the E17, it sounds more open to my ears. More air.
Or maybe I am just hearing the air between my ears?

Just received my M-stage. It's quite the beaut. But it's a brick right now since i don't have my dac, rca cable, or headphones
