@AnakChan and @BournePerfect
Any chance one of you has access to both the HP-A8 and Zana?
A comparison of these two driving the TH900 would surely make my day!
I've not used the HP-P1 for well over a year as such I can't comment on using it with the TH-900. However I have used the TH-900 with portable amps such as ALO Audio Rx Mk3 or RSA SR-71B and the TH-900 is quite easy to drive. If we're talking about these kinds of portable amp, it's not a matter of whether they're better than a desktop but more like which sound do you prefer.
Personally I think my greatest concern for your proposed setup is that it seems to imply you want it for portable use and I think this is where the TH-900 doesn't do very well for at least 2 reasons :-
1) the TH-900 doesn't isolate well (although I'm tempted to consider Lawton's new earpads for the TH-900 to see if they improve isolation but not deteriorate SQ - those pads are only $100).
2) the TH-900 is quite fragile - my earcups have broken twice, once on the plane, and another at the recent Tokyo headphone festival. This headphone is too expensive to risk breaking/damaging. I just happened to be lucky to live in Tokyo and know the Fostex chaps who have been extremely generous in repairing my TH-900s under warranty despite clearly being user initiated.
I must say I'm rather curious myself in addition to MorbidToaster's comment about the the Cavalli Liquid Glass. That's not to say I'm not happy with my HP-A8 as it's performing very well, especially in it's DoP (SACD/DSD/DSF over USB) capability
Oh My.... I just saw the photo. Those joint really made from plastic ?
I think its failed design with angled-earcub , strained by its own weight all the time.
Almost 1 yr since the first release nothing durable-upgrade from Fostex ????
Back in July (see linky for pix), during a flight. Then the other cup broke when a head-fier member was taking it off his head in late October. Luckily this was at a show where Fostex chaps were just 2 floors below.
Dare I remind you that the HP-P1 only works with iDevices? It differs from the more recent CLAS -dB, PHA-1 & Go-DAP X in that respect.
I think if you combine the DP1 DAC + ZDSE, you'll have an awesome combination. The other DAC/Amp which I was keen on but somewhat expensive is the Invicta.
They're not plastic. It's a casted screw with a spring. Unfortunately that casted screw is not that durable. But at least when it breaks, it's merely a screw that needs to be replaced by Fostex.
I'd love to hear your impressions. make sure the HP-A8's been upgraded to the latest firmware (even the beta one - I'm on 2.01b now).
The HP-A8 wasn't mine, I had it only for a couple weeks so I'm not sure if it was the latest firmware. But I agree with you that the Eximus DP1 sounds better with the TH900 than Fostex's own HP-A8. When the ZDSE arrives, I'll compare it with the DP1 and Soloist too.
I've sorta concluded that I'm happy enough with my HP-A8 that I can't justify the price difference for the DP1. At least in Japan the DP1 could easily cost 2x the cost of the HP-A8. I think if I'm going to get an upgrade I'd like to get a significant jump up in improvement - this may be the DP1+ZDSE combo (or Invicta+ZDSE) rather than just the DP1 alone.
I've been listening to Anakchan's pair out of my Audio-gd Phoenix, which is a "wire with gain" type amp and liking the results, so I'd be surprised if the B22 was other than a great amp for them. I tended to like the Denon range out of similar gear too.
