    Hi, and thanks for your reply. The ZMF Atticus is actually a customer made TPE dynamic driver, not one of the Fostex mods. I’m sure the Matrix will drive it easily, just wondering about the synergy as the Atticus is said to favour tubes with its 300ohm impedance.

    Hi gLer, sorry for the missinfo!
    I was reading now Tyll's article about the TPE custom drivers, hence...let's wait for a headfier that actually tried these headphones on a solid-state amp.

    P.S.: Don't know if it counts, but my 600-ohms Beyers DT880 are easily driven by this amp.

    No probs, ZMF's newer headphones probably aren't as well known as I assumed :) Well worth a listen if you get a chance. I'll be able to give my impressions when I get mine, was just wondering if any current 3B owners have tried them out.

    After the complete burn-in seems to have no connection with the stock unit, except the tone that is somewhere in the same area. It is significantly improved the speed, the timing, decay, resolution and sound-stage becomes so generous in depth!! (excelent layering). The stock unit was so anemic and unmusical comparative to the one I propose. It is something else. Everything makes sense by the fact that the sound is airy, fleshy, reliable with a transparency and those micro-details and texture which reminds me of the electrostatic system Stax&eXStatA (keeping the proportions still: control, focused image and superior texture for electrostatics).:deadhorse:

    Slowly, slowly I have the feeling of disappearance of the headphones on my ears which brings back the emotion that frankly speaking lacking before. If you ask me if it was worth the wait for the complete burn-in (I think over 600/650 hours), my only answer is this one: it sounds incredible for the price I paid!

    Is the HPA-3U+ listed on the Matrix website the same device as the HPA-3U discussed here? My first guess is that it is a recent upgrade but I can't find any separate information on it or how it is different. Thanks.

    The dac chip has changed b/w the two editions. Rest of it is exactly the same.

    I went ahead and ordered these. At about half the price of the Deckard ( after holiday discount ) I couldn't resist. I've got brand new LCD2-Classic headphones. I've been running them off my Dragonfly Red for a few days. I figure I'll have the option of running the DfR (2.1v line level) into the analog input on these if I want to. Still waiting for shipping confirmation though so don't let me get too excited.

    I just want to drop in and say that I like my HPA-3B and the Hd800 a lot. I can hear lots of little details and nuances such as the flicking of guitar strings, vibrations of the violin bows, etc. Instrument separation and soundstage are also very good. Vocal is clean. The HPA-3B is a touch warm, and it pairs well with the hd800 when it comes to the treble peak. I have no listening fatigue even after listening to the combo for hours.
  9. trybeingarun
    Which dac are you using to go along with the rest of the setup?
  10. winja
    I pair the HPA-3B with my Yggdrasil. The Yggdrasil is in another league of its own, but that just to say the HPA-3B is capable of revealing details if it is fed by a good source.

    Did someone listen to the MrSpeakers Aeon Flow (open or closed) with the HPA-3B amp? I would like to know about this match. Thanks!
  12. raoultrifan
    16 ohms headphones, right? HPA-3B has an output impedance of 0.4 ohms in single-ended operation, so the dumping ratio should be very good with Aeon.
    Being a Class-A amplifier means that will drive dynamic and planar as well, with ease, so I see no issue in driving the Aeon headset.
    Also, the low-gain (1st position on the knob switch) would probably be perfect for these headphones.
  13. UpTo11
    13 ohms impedance, 92dB (closed) - 94dB (open) sensitivity. While these numbers are good for the HPA-3B, at least on the balanced output, I'm looking for comments on this match beyond bare numbers. Anyway thanks for the answer.
