Fostex HP-A4

  Just to share! Headfonia has a short review on the HP-A4:

Seems hard to believe that the A4, with a completely different DAC chip, would be better characterized as a "mini-A8" than would the A3 (the latter of which has a very similar AK DAC chip to the A8). Can anyone explain how it could be otherwise? I'm quite open-minded and curious about the A4, just haven't had a chance to hear it yet. This review seems counter-intuitive in some ways. Is the A4 really more V-shaped than the A3? This would be very useful to know.

I'll see if my local store has both the HP-A3 and HP-A4 demo sets and make a comparison. :) Stay tuned!

Given the U-shape of both the TH900 and the TH600 plus the sensible match with the HP-A8 I'd doubt that Fostex would give the A4 a V-shaped signature... but that is speculation of course. Would come as a surprise nevertheless...
The review seems to reflect the differences between the chips used in the previous Fostex DACs vs. this new model -- calling that signature V-shaped seems a bit far-fetched to me, but I'll have a listen in february.

I think he means V-shaped by direct comparison to the HP-A3 which is rather soft on both extremes (laid-back). He describes the sound as more punchy and dynamic, which is a common trait I've heard in many Sabre designs. That's great news, IMO.
I hope the A4 retains that slight sweetness that I love from the A3 (and, IMO, makes the "Fostex sound").

That would make more sense in my view, but it would have better then to claim that the A3 had more of an inverted U sound signature, rather than claiming that the A4 sounds more V-shaped in comparison. It makes me question what Headfonia considers neutral.
I guess the A4 is more aimed as a universal solution and it has a very good chance to do well there. Not a lot of competition in this market.

hello everyone, ive always preferred my denon ah-d2000, though the hd650 i quite liked as well (but boring for EDM and techno)

so i just bought a fostex th-600 from a very reputable member here at head-fi, but i am concerned about the setup, as i want the most synergy out of it.

i currently use a cambridge audio dacmagic (original) and a schiit asgard 2. i know that will be more than enough power for the th600, but mike at headfonia said its sound potentials change drastically with different amps, the more expensive the better.

i talked to a seasoned audiophile friend of mine, and he told me it is bs and the change arent really noticeable.

anyways TL;DR i was wondering if i should replace my setup with fostex's very own HP-A4, as it looks good both on paper and in real life, but i havent heard it yet.

can anyone give me a description of their experiences of pairing the th600 with the hp-a4??
i cant wait until i get the th600, and its quite easy for me to sell off my current dac and amp and order a hpa4 off

my dacmagic is neutral but very analytic sound, and the asgard 2 is slightly warm, laid back, but also very dynamic and energetic.

Moon Audio has this in stock for $399.99. Better than ordering from Japan for those from the States:
