    Excuse me what's the meaning of LO or PO?
    and one question I have thay does A5 change any quality of sound or it just only for higher volume to hear? ( my headphone audiotechnica ath-m50x is 38 impedance )

    Line out vs phone out.

    It will change the sound quality, though it really depends on whether you can hear it or not. To me it's very noticeable even when driving sub 50 ohm headphones. To be honest every element in the chain changes the sound (port, transport, interconnect, headphone cables, etc).

    yes I think I need to train more my ears to notice the changes in the chain. then you recomend to keep my A5 even If I buy new player like AK JR?
  4. haoyuan
    I wouldn't get the AKJR. Assess what your needs really are before deciding on a player. Chances are you will outgrow it really quickly.

    I'm a newbie in these things, then how about buying X5 3rd gen?for start I just need a player that I could feel diffrence between simple mp3 and 16,24 bit flacs.

    You should get a DAC like the Fiio Q1 Mk 2 or something.

    I already have a A5 amp, and I want to remove the mobile phone from the chain and because of that I asked for a player that have good dac/amp. and in someway carrying that chain like a5,mobile,q1 would difficult. what do you suggest for a player ? in range of max 350$
  8. superuser1
    You can either look at the Cayin N5ii or the Shanling M3s. Both would have enough power for your M50x

    Dear friend,

    LO-Line out--an analog electrical signal not go thorgh the internal amplifer. Generally, the volume from line out output is not adjustable. You would collect the lineout port to Amplifer before collecting to the headphone.
    PO-headphone output--an analog electrical signal go thorgh the internal amplifer. You could collect the headphone to that port directly.:dt880smile:

    Best regards

    i have a e12 mont blanc, if i buy the A5 will i notice an improvement in sound?

    will it be louder or easier to drive my Amirons and M50x and Fostex tr70s?

    Sometimes i feel the E12 doesnt hove enouph power to drive my cans,,, like if i connect my cans to my ZXR sound card this sounds much better than the E12

    Just thinking if the A5 is worth upgrading to the A5???????????????????
  11. WitzyZed
    (Forgive me if I make minor mistakes in terminology here) I you have an OG Mont Blanc, into a 32 ohm load it supplies 880 mW, if you have an A5 it supplies 800 mW. So A5 is actually less powerful. Slightly. But it's using Muses 02 op amp instead of the LME49710. I recommend reading Brooko's review of the A5 he has a good chart (might be FiiO's) comparing the specs of all three.

    do you have the link?

    basically i need to know if the A5 is an actually upgrade in terms of sound quality compared to the E12 MontBlanc, I used the mont blanc for over a year now and I believe the A5 may have a better sound quality in terms of clarity and bass.

    But i dont want to buy it if it sounds the same, all ive researched so far that it has a better battery life, forget battery the sound is what im interested in..

    I can't seem to link directly to it, but it's the second review found here: https://www.head-fi.org/showcase/fiio-a5-portable-headphone-amplifier.21888/reviews .

    *Edit* As someone who owned an E12 Mont Blanc then an E12A afterwards, you're going to get a black background, very clean "wire with gain" is all an amp needs to be. The bass boost is also centered lower than the OG E12.

    I haven't been using my A5 despite buying it in 2016 - just hate the Muses02 signature. Why give such a coloured, warm OPAMP that has no definition and articulation.
    So thought of doing some mods - to begin with replacing the Muses02 with a DIP 8 pin socket. Thereafter I put LME49720NA. Together with current buffer LME49600, the clarity of this combo is breath-taking.
    One thing I noticed about A5 is that it sounds correctly damped only with 1V rms LINE OUTs, with anything above ~ 1.4V rms, it sounds over-driven, dynamics are crunched and sound harsh.

    Some pics of my mod. It's funny just by the sheer difference between Muses02 and 49720, A5 sounds like a completely different product altogether.
