Rudi, IEM = XBA 4x?
How is the PHA-1?
Hi AJHeadfi
thank you for the correction
It is XBA 40
PHA - 1 is fun sounding amp
i need some more days for burn in and I write my impression .
How long is the battery run time for you guys and at 5x the price of my Fiio E7 is it worth having even for a Sony die-hard?
The battery run time :
1. For use with I device ca 4 to 5 hours max
2, for use as pure amp ca 8 hours
sq is far above Fiio E7 , it's different price range
The Fiio E7 and this share the same Dac chip but the Fiio is 12/48 while the Sony is 24/96.
I would mostly be plugging it into my Walkman LOD, I think only 8hrs as an amp would kill me. The Fiio's 80hrs is just ridiculous in comparison.
Ill keep researching and saving, maybe ill get one.
Finally got the PHA-1 after waiting for a few months for the stock to arrive. Great build quality and design. Love the overall size and weight, and great ergonomics for holding and stacking the idevices with its clever elastic straps. Considering its price point vs CLAS Solo + RX Mk3B, the sound quality is not bad. Sounds great with most iems and at high gain is adequate to drive my W3000 and TH900, though that is where CLAS Solo + RX Mk3B really shine with the big cans. Got to burn in more and see how it goes.

Bon voyage evolutionx! Please let us read your impressions.
My beyerdynamic T 5 P set up
source : AK 100
dac / amp : Sony PHA 1 for i device
headphone : beyerdynamic T 5 P
headphone stand : glass woody by Jaben
Today I have tried my Sony PHA 1 with many different headphones
source 1 : AK 100
source 2 : iPhone 4 S
dac amp : Sony PHA 1 with Dac for i device only
headphones : beyerdynamic T 5 P
Fostex TH 900
high : open dan detail but is not bright or roll off .
mid : analog / tube sounding midrange , this is the strong point from Sony PHA 1
Bass : deep with very good bass impact .fast tranciant bass
Separation : very good , that I can feel where the instrument placement in the orchestra .
soundstage : wide and depth are very good
backgound : very black background
conclusion : Sony PHA 1 is sweet sounding Dac amp combo with the right high not Bright and not harsh or roll off .
The strong point what I love is the midrange so sweet like phono / tube like sounding mid .
The bass is deep and very good impact
this is my personal impression
Thanks for your impressions Rudi. Seems like strong competition to HP-P1. T5p is quite a strange headphone, but how did you get the TH900 into the PHA-1? I think TH900 has sweet midrange is it more enjoyable than T5p in this setup?
Beyerdynamic T 5 P is different class to Fostex TH 900
with Fostex Hp P 1 sound quality with Sony PHA 1 more fuller sound , more detail and more clarity and has better bass detail .
overall TH 900 more enjoyable than T 5 P
Thanks rudi0504. Still burning them in before some critical listening and also with other iems. Thanks for sharing your impressions.
