If you intentionally want a lower sampling rate/depth, you will have to convert the files yourself, the AK100 has no setting to re-sample them on the fly, it will use the original rate/depth.

Please share your impression here

I like to ask you about :

1. How is the power ? Is RWA AK 100 has more power than standard AK 100 ?

2. How is the sound quality ? Is that some improvement SQ from RWA AK 100 ?

3. What is the benefit to buy RWA AK 100 ?

Thank you

RWA AK 100 is a modified version of original AK 100 by Red Wine Audio USA?
Just curious, what kind of modification is being done to AK 100? What is the modidication cost?

So its now less than 1 ohm after the mod and suitable for both sensitive and harder to drive IEMs and cans. Using a stock AK100 on the other hand is not a viable option for sensitive IEMs.

It's $250.00 if you send your unit into Vinnie to mod or if you purchased directly from him $889.00. But he has been having problems getting stock in after having a fallout with iRiver. So it may not be possible any longer to acquire the units directly from him....

Removing any component from AK-100 will void the product warranry?

I think it goes from the discrete circuitry doesn't it? The dac doesn't have the output to power phones adequately and isn't meant for that purpose.

Ruid I think Viscerious (if I spelled him name correctly lol) has or had both units and he compared them to my knowledge in his review. He found the RWA AK100 the clear winner with sensitive IEMs and that it had slightly more power as well.

 

I've never found the unit to lack in overall volume myself. Just the urge to listen to it at dangerous volumes is what really puts me off of it (lacks dynamics IMO at lower volumes).

Despite opening up the soundstage, the whole thing sounded a bit thin at any level (not maxed out), compared to what I'm used to. Put them on one of my favourite amps, the Peachtree, and the magic was back (still same set) So definitely, with some headphones, the AK100 sounds comparatively thin. And this was a clear difference, I'm not the most picky of Head-Fiers. Not night and day, not unlistenable, but nonetheless noticeable.
