If I bought the hp-p1 I'd be using them with my slightly portable ATH-M50's. Do you think I would notice a vast improvement listening with my Ipod Tough 4G? All my music is mostly 320kb mp3 files. I don't really have an opportunity to listen before I buy. I also currently have a Nuforce Icon HPD for my desktop amp/dac combo. Any idea if it would be similar or better in sound quality to this with the M50's? As I notice a fair improvement with this and they both hover around the same price range. Thanks in advance for your help smily_headphones1.gif

I would expect a similar experience to the HDP. You would certainly see an improvement over the iPod.

Hi from a newcomer

 

just got my hp-p1 today and loving it :-)

 

just... what I don't get is: how comes that after 6 hours, when the p1's battery died, the iPhone's battery still was at 100%? :-/

is the amp also charging the iDevice while playing?

 

thanks

Yes.  Also battery time is six to seven hours.

Yes, it trickle charges the ipod. Nice  eh.

 

so when the Fostex runs out of juice you can still use the ipod by itself as a last resort:)

yup: tried again today and iPhone charge went from 85 to 95% in 3-4 hours of use

honestly I'd rather prefer the hp-p1's battery to last longer and *not* trickle the iPod/iPhone one (that already lasts way longer than the hp-p1's) but... ok :-/

 

 

btw: today I've used it connected to my home stereo and... sounds darn good :-)

well... almost anything sounds good with SE tubes :-p :-p :-p

just kidding ;-)

 

thanks Expatin :-)

Just keep your iPod fully charged and the Fostex won't have to trickle charge it and lasts longer. Upside is I've never had to charge my iPod in 6 months of daily use

... great suggestion, thanks :-)

Awesome combo! I am enjoying it again at 35,000 feet. It is crazy what we can do now remotely with an iPad and a small portable rig. biggrin.gif

wow tahnk you, I just got a Fostex HP-P1 with the edition 8, and noticed the popping imediately, also on my Westone ER4P; did the reset and problem solved!!!!  Infact everything sounds better!!!!!!!!!

post #685 of 1305

Throw some lossless files at that combo and you will really enjoy it!

I just got my Edition 8 tonight, and my Fostex HP P1 the day before.  I always try the headphones by themselves with the Ipod 3G.  My first impression, the representation of the music on listening to about 4 tracks of mostly acoustic, with a Bass, and vocals, and one Jazz composition, with a beautiful sax solo; is wow the edition by themselves, sound great, and better than my Beyer Tesla T5p; richer, luscious tone, more Bass, a bit more fun to listen too, but equal sparkle to the Tesla 5P.  My next reaction was why bother with the Fostex at this point.  Between yesterday and today I was getting crackles anyway with the Fostex, that I didn't think were artifact because I am using Apple loss-less.  Then I did the reset I found here; and the problem of crackles is gone. Now to the Fostex.  I have read about amps, balancing out the music, so that there is appropriate emphasis throughout the range, and the music becomes most natural.  I didn't think I really ever heard that before with an AMP before, my prior is an ALO RX.  So i never was motivated to want to use the Amp.  Now I have heard it.  I can hear, how the entire spectrum is balanced, with detail throughout, and slightly better separation. By  balance I mean, I never realized how much definition was lost say in a group singing, or Bass that was over accentuated, or treble that wasn't really sibilant, but really was a tad fatiguing.   There isn't as much of a Wow, as it is a very pleasant experince.  Now that I have experienced that, unless the battery is down, by choice I wouldn't want to go back.  So now my conclusion is that, without the Fostex, if you haven't experienced it, you wouldn't miss anything, you'd think the Edition 8 alone are breathtaking.  However with the Fostex, you feel very confident about the tonality, the  representation, and the definition of the music.Obviously to me this difference is due to more than an amp alone, but the powerful DA Converter of a pure signal.  Don't get me wrong, at this point things start to get a little confusing, the music sounds awesome in all cases; but I think the Fostex add more than an AMP does, and once you hear that, you would want that, especially if you are listening through the Edition 8.

Great write up. Try the Fostex line out to the Alo Rx, would be interested in your thoughts on that.

Good Summary ChipB! I good DAC really sets things free...

post #689 of 1305

I've read 46 pages just to know if the Fostex HP-P1 is able to receive 24 bit /xxx Khz files from iDevices, but nobody is interested in clarify it???

Is that less important than changing dock to usb cable???

Just connect the optical out to a dac able to display bit/freq and report back please!!!

 

That way we could be sure that at least the digital section is passing bit perfect data.

 

It's sure iPad + CCK + USB battery powered HUB (like the D-Tech or Tekkeon, be careful not all battery powered USB charger pass data) + FLAC Player app (and others) can send 24/192 files to a lot of USB DACs (like my portable iBasso D7 even if it's not battery powered).

MAIN PROBLEM: STORAGE IS LIMITED BY THE IPAD MEMORY.

 

It's sure the iPad + CCK + USB battery powered HUB + iTunes Home Sharing (*) can send 24/192 files to the same USB DACs.

MAIN PROBLEM: WI-FI / NETWORK LIMITED RANGE.

 

I've tested successfully both configs with iBasso D7 digital coaxial out to Dac dispay bit/sample rate.

BTW, with my iBasso D7 I use the latter configuration at home just because it sounds better than D7 attached directly to the USB port of my Dell M6600 (clearer sound, more details, dynamic and better bass definition), and I don't want to became crazy with Windows 7 optimizations.

Another plus: I can also move around instead of keep myself attached to the notebook...

 

The main iDevices I'm interested are:

 

iPod Classic 160GB could be a good solution for hi res files (bigger memory and not limited by a wi-fi/network) but it's not compatible with CCK or FLAC player and other apps.

So if HP-P1 could do 24 bit /48 Khz which seems the limit of the iPod Classic loadable files, I could live with it while traveling ouside home. With dbpoweramp converter I could load same high res files with less memory space than originals.

 

If iPad + Fostex HP-P1 could do 24 bit /192 Khz it'll be the best with Home Sharing and FLAC Player and similar apps.

 

Thanks in advance for answering this silly question after more than a year and 46 pages!!!!!

 

 

 

(*) Other configs when not using Home Sharing are not up to the task:

Same config above + PlugPlayer UpnP app + various UpnP servers (Jriver, Asset, Foobar...) never goes above 48Khz no matter what settings is changed in the server, in the app, transcoding or not, wav or ALAC... The DAC show only 48Khz max from same coax out of iBasso D7.

I have ripped all my CD's to AIFF so the IPC has only those files playing through the HP-P1. It does limit you to about 3000 total songs for 160 GB but you get the whole file. FWIW the sound through the HP-P1 is terrific via my HD25-1 ii's.
