+1 to that....If I could get the HP-P1 in a Leckerton UHA 6S MkII sized case that would be nice....As long as the battery life was no shorter. Basically,though, I find the HP-P1 to be stellar!

I do know that cryo is hotly debated and there is nothing simple about considerations of using it. The HP-P1 just seemed like an easy candidate to try out. It does seem that with cryo treatment, if it doesn't kill it, it will make it stronger.

 

I really like my HP-P1, so I'm not willing to just "have a go". ;)

Looking to the future, could we make some wild predictions for when and/or will Fostex follow up on the HP-P1? 

 

Maybe for another company, similar to headphones for Denon in the past. Maybe a time frame of 5 years? 

 

I'm also wondering how could the HP-P1 be improved on? Apart from smaller, lower energy use etc. I would like USB input from another transport, so as not to tether to the iDevice, but not if that compromises sound quality. Would Fostex try to make a "jack of all headphones"? Seems impossible to me without compromise somewhere.

I would look at the Centence HiFiM8 as an example of where the industry is moving...

I believe it. Unfortunate for me though as I don't need or want any of its superior flexibility. The future for me may lay in new highly energy efficient full discrete. I want to improve on audio quality next, rather than tailor existing limits.

I appreciate that! Kinda the point for listening....biggrin.gif

I just posted this over on the UM Miracle thread. IMO the Fostex is a equal partner in the fantastic listening session I just experienced so apropos to share here.

 

 

"Just spent 10 out of 11 hours listening on airplanes.

 

1) the isolation/fit was amazing = 99% isolation 99% of the time. Remember we talked about how certain ways in a airplane seat, when I would turn my head, the right side seal would break? Happened twice FWICW. This is a 'WOW' since I am not one to sit still for long.

 

2)  the SQ........wide sound-stage, clarity, range, lows, airiness, simply amazing. At home I am using LCD3s and I would put the Miracles in the same class with these particular characteristics. Not quite as good, but for IEMs and 1/2 the price, NOT 1/2 the good of the LCD3, much closer. 

 

My rig used  iPod 160 > Fostex HP-P1 > RSA Hornet > Miracles. Not matter what song and no matter how loud I was willing to go, could not turn the Hornet past the first mark on the pot."

Pretty impressive for the Miracle and HP-P1 to compare to your home rig, Steve! I had a great 5 hour session this week with the HP-P1 and my ACS T1's.....Great little device the HP-P1!

People seem to particularly like the HP-P1's DAC with the AK4480, using the HP-P1 just to have it's DAC qualities.It's particularly nice when you can use the HP-P1 amp & DAC, as they are intimately connected internally for maximum transparency. I have suspicions the opamp used in the HP-P1 is designed specifically for audio use, would be interesting to know. I tend towards orchestral/jazz/acoustic music, and for that the HP-P1 works well, I like how delicate it can be.

 

In other matters HP-P1 related, just recently I had to return a Furutech ADL-iD30PA cable due to a volatile connection. The replacement which came immediately is fine and works well. It seemed to provide a further degree of only transparency to the system. No major but a minor improvement, worthwhile for the HP-P1 has a delicate sound. I have my Fostex 30pin-USBA as a backup. 

 

I tried using the HP-P1 & DT1350 on public transport, the isolation is not sufficient to afford full appreciation of the HP-P1 or the DT1350, to say nothing of the vibration through the body. I suspect IEM would be better, but my Etymotic HF2 with ACS moulds waste the value of the HP-P1. I most often listen to the HP-P1 in a quiet environment with T5p now, at a desk, armchair, before sleep.

 

...and good to see people still enjoying the HP-P1! beerchug.gif

AJ, I used the HP with the Miracles and FT!334s without another AMP and was happy. Then I learned about impedance and the HP has 10.22 which means  (conventional/traditional wisdom) that a HP should have 80 impedance. The Miracles are 15.9 and the 334s has 45......so, I continue to use the 334 without an AMP and the Miracles with.  I should A/P with and without for the Miracles, however, it's hard for me to hear differences or to know I am hearing any LOL

 

Anyway you are right and Longbowbbs and I agree.....the Fostex HP-P1 is very enjoyable!

Amended to include Expatin who enjoys his too beerchug.gif

i have been using mine with the accudio app, gives it even more clarity imho.

Interesting. I'm wondering what processing equaliser software does to the PCM code? I prefer not to reprocess the PCM, so not even "flat", simply none. Whatever the guys that mastered the PCM did is what I'll consume.

 

Accudio lets you experience T5p signature? How do they come up with that?

post #853 of 1319

No idea, but when I flip it FROM the great accudio app (ATH-ESW9 or TF10 reference settings) .....BACK over to accudio audio normal/flat?, ipod stock normal, flacplayer app normal it just doesnt sound as good to my ears - it sounds dark, damp and musty clouded over.

 

Demo-ed the free accudio app first, found I could add FLAC to it If it is single tracks, not full albums. Good thing is FLAC, ALAC, mp3 etc show up on the screen together, but partitioned off which is great as I hate having to use ipod stock player for ALAC and Flacplayer app for FLAC.

After a trial I decided to buy the full app.

 

*Key point here. Tried  quite a bit of switching between the players above and the end result is ..............I find myself more lost in the music and nodding my head along to it, .......which I havent done in a while. No more critical listening to my files or gear, just back to enjoyment of the music which was my initial aim in this journey before the game of overanalyzing my gear took over.

 

Actually I have no idea what they have done apart from trying to get a flat ~ish response from headphones, but i certainly like it a lot.

 

I  hung up all my other EQ apps a long time back, I still use flacplayer with no eq though. So i was surprised by this app. Anyhow the free version is there, so no harm in trying.

My T1's are 17 ohm....Great pairing!
