New Fostex HP-V1 Portable Amp - Page 4

post #46 of 118

It may be possible but valves are quite inefficient (especially in class A operation), so BIG batteries are needed to give low output power, making them less portable and more transportable. Mains has been the way to go for power hungry headphones and valves. However ... miracles do happen.

Not sure if this has been posted before? From www.fujiya-avic.jp

 

Looks like a USB power input?

You're talking about the cable in the background with the reactor coil? Yes, that could well be a USB cable used for power.

AJHF, I was told,that the HP-V1 date is now early next year. They seem more certain than previous inquiries about production timelines.

with iDAC & USB DAC options would have made a far more interesting product. But maybe they want to feel the waters and see how much interest they get for this portable tube amp at the price point they will be asking.

Looks like Fostex is almost ready to deliver in Feb (most likely for the Fujiya Winter portaken festival on 8th Feb?).

 

e-earphone just put up the HP-V1 in their catalogue at Y54,600 (Approx USD$522). :-

It looks better every time some new info comes out. I'm glad they have stayed close to the portable ethos. The proof should be in the pudding. I can't read Japanese info, however looks like 200mW/32ohm, 3.5mm sockets, 20-200kHz, all fine so far.

 

ADD: And 6N16B-Q Soviet valves.

At last the HP-V1 is now on their official website:

At 390g its not a thing I'll carry around day to day though...

I guess you mean out on their international site? for Its been out in Japan since 1st Feb (before that they were taking orders). I had a listen to it again at the Fujiya Portable Event :-

 

 

I was really tempted to pick one up at the show especially when they had specials (5x going for Y42,000+ each) and I had just dropped off my TUR-06 for repair. Unfortunately it didn't have enough grunt to drive my Alpha Dogs (but naturally drove the MH335DW easily). It wasn't microphonic as far as I can tell and that's extremely welcoming for a portable tube amp.

Yes, new to the international site... we're kind of second-class buyers I guess ;-)

This will compliment my HP-P1 perfectly. Hybrid technology may be gaining more momentum, like d class amps.

 

Let us have a TU-06 vs HP-V1 shootout! Yeeha

Does this mean an output impedance of 2ohms?

I think it means you should be driving headphones of 16ohm or more.
