Thanks Punk_guy
It's $30 shipping to Ireland for me when I choose USPS. Is it not cheaper for you?

$22USD for me but I think it is a fixed price, you can order a whole bunch and the shipping fee will not increase I think.

Another charger option?

Would this perhaps be an option (for the time being):

Ni-MH Ni-Cd LiFePO4 Li-ion battery smart quick charger! - eBay (item 220524411144 end time May-08-10 08:53:51 PDT)

Very cheap.

For the boxed HiFace it would probably be to much hassle. But with batteries outside the boxe you could just put them in a charger. No idea how long full batteries would last.

That could be an interesting alternative if this charger is compatible with jkeny's batteries. We could save some $$$ also.

No it's for the wrong sized batteries - my ones are 26650 size & won't fit.

Here's what I'll do - I'll build these cable converters Tamiya to 2.1mm DC plug & include them with the units I send out for those that need it. That way you guys can order the ebay unit for the cheaper shipping option 3.2V 2A Smart Charger for Single Cell LiFePO4 Battery

I wonder if I could have such a mod done to my Audio-GD Reference One DAC or Phoenix HeadAmp/PreAmp for a relatively low price.
Thats exactly what Red Wine Audio does!!! Take a look at their products, they get great reviews!!

They have an entire lineup of devices working off battery power. Pretty interesting stuff.

Will the modded Hiface work with the Lab Brick USB hub supplying 5V power? I'm not really interested in the modded USB cable.

Yes you can use any USB cable, powered hub or whatever - exactly as you could do with the stock Hiface.

Curious, how do you think the battery powered Hiface compares to this guy:

Audiophilleo1 - advanced ultra low jitter USB to SPDIF transport

One can never tell until a real test but the specs of that device look very good & it reads very well i.e most of what he says makes sense - I would like to hear more about his custom designed USB receiver, "virtualcable" & "jitter simulator" though (I had already sent him an email before this post).

The weakest point in the whole design is probably the regenerative power supply i.e he is getting the power from the USB 5V. His approach is correct in that he has isolated the clock handling parts from the USB parts. He has also claimed that his tests show battery power to make no difference to the jitter output. All I can say is that the batteries I use have been tested against some of the best regulators available using heavily filtered supplies fed from an 1KVA isolation transformer & the batteries easily beat all regulators! Batteries (Hiface USB Transport Modifications & Ancillaries)

Like everything it depends on implementation!

He has experimented with batteries in the past, he prefers AC. Your ref 1 is getting clean power. Trust me.

Hi all,

How much are the modded boxed versions selling for?

Cheers,
Rift.
