    I’ll be honest and say that the Phonitor’s VU dials almost had me sold right away 😉

    Do you recommend OPPO CD player???

    When the upgraded HiFiMAN 801 will be available??? …I mean the one with a upgraded amp.

    How with it sound with HD800 & JH16???

    From your personal choice which desk top amp would you recommend for an optimized HD800 listening ???

    Thank you your site is great

      Hi Ivan. The Oppos are supposed to be good for the price, but I never really tried them myself.
      I believe the HM801 with the GAME amp is already available, and the amp is optimized for IEMs. Please contact Hifiman about that. The HM801 combo with the HD800 and JH16 sounds very good and will challenge many desktop systems.
      As for a desktop amp, wait for the Burson HA-160 review, perhaps you will like it. 🙂

    Mike,

    how do you compare the Auditor/Phonitor with the CEC HD53n ?.

    In particular for pop, jazz, and female voices what would be your take?. thx.

      Hi Cortes,
      Pop, Jazz, and Female voices, I would take the CEC HD53N over the Auditor/Phonitor. The CEC is tuned to be colored in a pleasing way, where the Auditor/Phonitor is a very neutral colorless amplifier.

    Hi Victor,
    Unfortunately I don't have the Phonitor anymore. It's a very neutral amplifier. What headphone are you using it with currently, and how do you like the combination?

    The LCD-2 is a very easy to like headphone, and I feel you can enjoy it with the neutral sounding Phonitor. Just make sure that the Phonitor can do a good job of driving the orthodynamic driver.

    Hey mike, great review. Since I don’t have enough money for the Phonitor, what crossfeed plug-ins would you reccomend for use on a Mac? Windows?
    Thanks.

      Hi Yoav,
      I’m mostly a Mac user, and for Mac I use the Canz3D. The amount of
      control you have with that plug in is quite in depth, perhaps even more
      in depth than the Phonitor.

    Hi Mike,

    Could you tell how the auditor paired up with hd800? I’m getting mixed views from a different forum.

    FYI

    I will be using the cambridge audio 840c (similar to dacmagic) as my source.

    Thanks in advance.

      Hi Harj,
      The Phonitor and Auditor amp has what I would call an ultra-colorless, sterile in nature sound. It would be perfect for monitoring, but usually music listeners would like a little more color in the bass, in the mids, and would find them too flat. Pair it with the HD800 which is also semi-colorless, semi-sterile, and you’re looking at a very flat presentation.

      The Cambridge 840C, if I am not mistaken uses an AD1855 (or AD-something chip), rather than the WM8740 in the Dacmagic. I may be wrong though.

    I now own this unit and the Senn. HD-800. These are a great combination for me.

    Hey, can you let me know if the Auditor has enough power to drive the Hifiman HE-6 to high volume without clipping?

      Yo,

      The Auditor does not have enough output current to drive them well at all. I’d recommend something like the Schiit Audio Lyr or Violectric V200.

        Mike

        Yes or a speaker amp.

    I own the Auditor and it’s an exceptional amp with the most neutral sound I’ve ever heard out of a headphone amp before.

    Hi Mike,

    would you recommend SPL Auditor for AKG K702?

    thank you in advance

      Jaro,
      If you are looking for a super-neutral set up, then yes. Otherwise it may lack a little musicality for music listening.

        Hi Mike,

        sorry I forgot to be more specific. I meant in term of driving them properly. If I am not wrong Auditor output impedance is quite high, so I am worring about damping factor.

          Sorry it’s been so long since I did the review. All I can remember is that the Phonitor / Auditor amp is extremely neutral. Good for monitoring but not really my favorite for music listening.
