Sony PHA-1 portable DAC/amp - Page 2

The article states that the WM-Port of the Sony Walkmans don't output digital so it's really just a LOD cable outputting to the analog input of the amp, which makes the DAC portion of the PHA-1 useless in such a setup.

Guys, is it just me or does it seem a little on the chunky side?

Thanks for the link.

 

It sure looks nice on the outside, I hope Sony has made it just as nice on the inside.

 

It's about time they made a dedicated headphone amp, the price is quite a bit higher than a lot of the stereo receivers though and they're not exactly in the niche sector.

Have you seen the HP-P1???  this one looks chunky but looks like it has better form factor to accommodate a strapped idevice.

 

The CLAS itself is slim but it needs another peripheral. Thats just ..  too messy

Okay, fair enough.  I guess I've just been spoiled by Sony's usually stellar miniaturization efforts. smile.gif

I hope to be able to review the PHA-1 soon which I can put up against the HP_P1 and maybe (if I can get Anakchan and shigzeo together) also a CLAS/AMP combo and a Go-DAP unit as well.

On a side note, the crossover-less of Sony own XBA series might go well (better than typical multi-way IEM) with this amp.

 

So the Sony XBA series will sound better with high output impedance than typical multi-way IEM's?

I have the feeling this amp is using really lacklustre internal parts and there is something amiss with Sony's latest dev. team. =/

 

Like, 4 1/2 hours of portable WM8740 sound for $600.................

 

Come on they could at least use the LME49990.

 

...or the internals of a famous Sony Discman instead.

A bit early to say about implementation, don't you think? A little faith for sony's dev team, they do design good products. I do agree that the current audio lineup has been frankly, rather crappy in a way. Their older products still seem to outshine the newer ones to me.

 

bleh corrections, @kiteki yes

Sony makes amazing products like the PS3 and inventing the Discman, Walkman, Minidisc........ so releasing something that is essentially a circuit optimized Teclast T51 at 4 times the thickness and 4 times the price is a disappointment when they have the capacity to release something completely new or use the internals of a classic Aiwa walkman with modern amplification.

Looks pretty interesting.  This might be nice for people who feel that the Fostex HP-P! is too expensive, and are looking for a USB DAC capability.

At 50000 yen, it better compete with the HP-P1.

If the fostex is too expensive, you will be better of looking at a Go DAP X.

Another transportable unit with DAC chip that is not really audiophile grade. Dont see how can they compete against the fostex which seems to be technically more advance and feature wise far better, with not much of  price margin differences. 

 

Bottom line:At $300 to $350 this would be a great unit, at $400-450, it is just  fashion statement, at $450-500, it is a rip off.

No, that's not what I mean. One of the most obvious effect an high output impedance does to multi-way IEM is that it changes how the crossover behaves because of the added impedance to the RC circuit. This changes the corner frequency of the circuit which result in boosting / reducing in certain frequency range / coloration. Since XBA series use mechanical crossover instead of electronics crossover, high output impedance will have much less negative effect than on conventional multi-way IEM. Basically, less / no coloration = better.
