Sony's DSD-capable PHA-2 portable headphone amp/DAC

post #1 of 567
Thread Starter 

 

Sony have just released information about the continuation of the PHA series. Their new PHA-2 DAC/headphone amp will support DSD at sampling rates of 2,8 and 5,6MHz. It looks to share the same form factor, but sports a couple of improvements to the design. Yes, you still get the roll cage, but this release looks much closer to a single box solution for almost ALL portable needs.

I hope that L/R balance is fixed along with performance with low-Ω earphones as well as battery life.

Looking forward to impressions and opinions. 

 

I will be going to the Fujiya show (barring the flu) and along with other headfier's sharing my views as they evolve.

Interesting. Sub'd.

That's very similar to the VC SDT.  However, the 1795 is a bit older than the 5102A.  Will be interesting to see a comparison in the future.

I am also very interested. Can't wait to hear it come October.

Nice that it has a line out.

Like I said, the first one was very cool. Its price put it up against some better sounding stuff, but not a single DAC/amp offered the polish, the low noise, and the functionality with such polish. I do very much hope that this time L/R balance at low volumes and low Ω earphone/headphone performance is better. Battery life... I've never used an amp system as a DAC for more than 5 hours in a portable situation, so I'm not the best judge.

Any idea what's the output impedance ?

No idea, but they will be stupid not to have it match their new MDR-10R and XBA-H3.

Noob time. What is DSD?

BTW Shigzeo, missed reading your TOUCHMYAPPS.com. The last article I read we Forza Audioworks whom I've ordered a few cables from.

Direct Stream Digital, which is a really high res master quality format.  2.8Mhz is 64 bits DSD and 5.6Mhz is 128 bits DSD.  You can get some samples from 2L.

Okayyyy but DrSheep, what does that mean in real life use? Can you help elaborate. Thanks.

Doesn't mean a whole lot unless you rips SACDs, which is a niche in an already really niche market.  If you want to know more, go read up on the AK120 or VentureCraft SounDroid Typhoon threads or just search for SACD ripping and DSD.

Amazingly, I'm getting people writing that an MD or CD re-ripped into DSD will sound better than the source. Reminds me of 1998 and the MD-is-better-than-CD nonsense-spouting hoosiers. Technically, DSD is capable of better sound. Whether or not the human ear can hear it or not IS up for debate. The thing is that comparing on equal footing is hard because:

 

1. SACD/DSD often are mastered differently to CD/DAT/DCC other 16 bit audio; this of course renders comparisons suspect at best.
2. Finding the same recordings. DSD is still hard to find. Even if you do and you get one that has as closely as possible been pressed from the same material as the CD was, volume differences can muck up the comparison.

But high dynamic range at high volumes and low noise at low volumes are probably the biggest technical upgrades to the CD. Again, the two cannot be compared on the same ground, so... but having hardware that supports DSD and everything else isn't a bad thing at all. Today is a very rich day for the audio fan.

Thank you. Apart from a few small articles, I'm not really writing there anymore. I've moved over to Ω image and will try to pick steam up again. My focus is a bit different to before, but I hope that I can still be helpful to prospective buyers. I'm about to pull the trigger on an expensive earphone that gets some bad and good (mostly bad) press. I tend to like to hear for myself. Falling resell value will kill it if a bad investment, but I'm purchasing it for a variety of other reasons! 

Anyway, your encouragement is helpful. I hope Ω will be okay instead.

I hope battery will last more than the PHA-1.
