    Have you anywhere compared A5 sound with E12A? Based on your comment here, it seems that A5 has more treble extension and less smoothness compared to E12A. Does it also mean that the A5 can bring out more details

    Yes, I felt like A5 was more neutral, E12A was really smooth and didn't bring the treble forward quite that much. It was nice if you wanted a leaner experience, but for most uses, I would go with A5. I think A5 is the portable AMP to go from FiiO, although I would also consider Q5, which is much better in every way (though also considerably more expensive) :)

    hello, through mount blanc family has similiar charging input recomendation (5V 2A) is it okay to use a charger above 2A ( I has 5V 3A charger) and use a powerbank ?

    Thank you. Fiio X5iii already has warmth and the E12A in that scenario may just increase the warmth. A5 is perhaps more transparent

    Absolutely. Just don't use a charger with higher voltage.

    I am using a Fiio X5III+Fiio A5+ Sennheiser HD 598. I am currently experiencing a very peaky, sharp and piercing vocal via the A5. All other facets of sound seem to be fine, but the vocals are very thin and piercing. Does anyone have an insight over this. Didn't hope the A5 would just kill vocals like this

    I think the problem is your headphones, I used the x5iii and a5 combo with my HEX V2 and it sounded great. the hd598 probably wouldnt sound any different with or without the a5 amp

    I had a Schiit Magni 3 before A5. Via the Magni the 598 produced richer and deeper vocals even on high volumes.

    Try different headphones on the A5. Then try the headphones and source without the A5 in the chain. I think it's your headphones too.

    Make sure you volume match when doing comparisons, and use a proper SPL meter and test tones to do the matching. Half the issue is that people don't properly volume match or try to to do it "by ear". End result - usually the output from the amp is slightly louder - and we perceive louder as more detailed, richer, better sound-stage etc, etc. Its how we are wired, we can't escape it.

    Most people think they are comparing what they hear. To truly do that - you have to eliminate all bias as much as possible. First thing is making the playing field even (same tracks, same source, same volume). Second is removing other influences - blind test, someone else doing random switching. You'd be amazed how our preconceived impressions change when you that.

    BTW - one way you can have deeper bass or richer mid-range is subtly introducing higher distortion levels. Its not really high fidelity, but there all sorts of tricks to this trade :wink:

    Thank you.
    I still want to make the vocals bigger and take away some of that peaky sparkle from vocals. Is there a way to do that through equalization. Can anyone suggest how to achieve that through equalization?

    Which headphones are you using?

    OK - that's really weird - for a few reasons.

    1. The A5 is almost completely neutral - measures dead flat, practically wire with gain.
    2. The HD598 is not a bright headphone. it has a 10dB rise at 3-5 kHz and another one at 9-10 kHz. 3-5kHz is mostly too early for sibilance. 9-10 kHz is too late. So your description of the A5 or HD598 being a cause seems strange
    3. The HD598 can tend to be a bit grainy in the upper mids - because the bump is too pronounced - perhaps that is what you're hearing?
    My advice - drop the upper mid-range by about 4-5dB (EDIT 3-5 kHz) and see if it makes a difference.

    Also - check your music - perhaps it is also in the mastering? A hot track coupled with a headphone that overly boosts the upper mids can cause issues if you are sensitive to that frequency band. If that's the case - I'd sell the HD598 and look to get an HD6XX (Massdrop version of the HD650)

    EDIT - corrected freq range
