  no ...of course not ... as long as the voltage remains 5 volts ... the extra amperage don't harm  ... i charge my walkman with the usb hub 500 mA .. external charger 1.2 and 2 A without any harm 

the recommended  charger by sony for this amp is 5volt 1A 

Ok, my bad

Nothing bad my friend.. We are here to be useful and inform each other

With the A-17 do you use the digital cable that comes with the PHA-1 and does the battery life of both Sony items then take a dive?

I do use the cable that came with the PHA-1A and I am not having any battery issues.

I know that my Etymotics are not the earphones de jour and that some of you like the bass thump that seems unnatural to me. I love my music as flat as it comes. That being said, I have to say that I am really coming to love the way this setup sounds. It has become very engaging over time.

i believe that amp needs a bit of burning in

Same here.   I would imagine that the A17 being hooked up to the pha-1a would use less of it's battery as it's no longer using it's internal amp to power headphones.   I used up the battery on the 1a in around 6 hrs, yet the meter on the a17 was still reading 3 bars after a full charge.

I have had my Etymotic ER4s for 15 years and they are still making me very happy, especially as the rest of my equipment improves.  Just alone with the NW-ZX2 they are great.

I use my custom earpieces on mine and it does make a noticeable difference.

So.....it seems like this questions hasn't yet been answered:

How does the PHA-1A compare to the Oppo HA-2??
Not considering the bass boost on the HA-2, that is.

The 20% off coupon for select headphones in the official sony store also works for this amp, I'm not sure what the rules on posting codes are but a quick google search will take care of that. Needless to say ive got one on the way, after shipping and tax it was about $260.

So I received my replacement and the treble and brightness are less with this one. I agree with the poster who said the first one I had maybe defective. I also tried my Audio Technica M50 32 ohms with the replacement and it sounds darn good, the bass is there, heard and felt. I think that my Beyerdynamic DT-770 250 Ohms was aiding with the brightness and not helping. I wish I could find a headphone just as comfortable as the DT770. I could try and get the DT770 80 Ohms since I read that they have bass that the 250 ohms version lacks or get the M50X.

I was about to get the ha-2 (I'm a unashamed Oppo fan boy) but changed my mind when I saw the cables needed to use the ha-2 and the a17 together.  Sonys solution was much simpler with their 'proprietary'  cable included.   Sorry Fizban, I can't answer how the sound differences  are between the two amps but can say I am completely satisfied with the pha-1a.   After a week with it, the sound is opening up to where I don't care what other amps sound like, it's a very good match with the a17. Color me saaatisfied
