Fostex HP-P1 Portable Amplifier and DAC for iPod/iPhone (Short REVIEW and Impressions Thread) - Page 11

@Mkubota1, I think U're onto something there about matching amps to earphones. I wasn't that impressed with the P1 & TF10's. The FX700 bridged the gap between the P1 vs P1+Predator. BTW, good to know about the iOS5 upgrade too. Thx for being the first to test & report on it.

Since we're showing custom IEM's with our HP-P1, here's mine

Hey AnakChan, what Beat Audio Cable is that? And the customs?

UM SE530x8 & Beat Audio iPhone cables from Custom-IEM.

Just wanted to post up some pics I finally managed to take of my rigs:

Looking at getting this for portable use, as well as bedside use.

I intend to get a very high quality dac and amp for my bedside rig, but I'd still like to use my iPod, which is what makes the transport function perfect.

 

My question is whether or not you can use an external DAC instead of the one included in the Fostex. For portable use, I'll use the Fostex's amp and DAC and I'm sure it will sound great, but I'd like to use stand-alone components for my bedside rig.

To summarize, I'd like to know if this can be used simply as a transport, bypassing even its own included amp and DAC for use with stand-alone components.

 

Sorry if this question has already been asked!

Ckaz, yes, the Fostex has a Toslink (optical) out allowing you to bypass its DAC and amp. So if you have an external DAC with Toslink in, you can use the Fostex just to extract the digital signal from the iPod.

HI, 

 

Does anyone know if the HPP1 can be charged by connecting the USB cable to an ipod power charger? 

Yes, I should think so. I use a generic usb wall charger adapter. Same as I use to charge my iPod.

 

Hi HP-P1 owners,

 

Just FYI, I was at the Headphone Festival in Tokyo today with a few other Head-Fi'ers. At the Fostex booth, they offered to upgrade the firmware of my HP-P1 which apparently reduces the battery drain of the iPhone when used with the HP-P1. So if you find your iDevice battery draining quickly when used with the HP-P1, Fostex can fix that.

Thanks for the tip, I'd like that! Hope it also works for iPod Classic

 

Hi, 

 

Does updating the firmware involve sending the unit back to Fostex?

I guess so, I actually didn't ask them if one could do it by themselves. The guy just asked me for my HP-P1 and just did it, I didn't even ask or knew abut the firmware update. I don't even know the former and what the new version numbers are. Apologies, I should have asked him more questions.
