Interesting observations. How are you streaming 192K files?

I've been playing around with my iPad and audio streaming. Using the Vaunix hub in the middle to allow the iPad to work with it, I had it almost streaming 192k. The AP1 showed 192k but the music was distorted.  Going back to 96k files, they sound better streamed through the iPad than direct from my MacBook Air. Not sure if the "better" is actually better or not, but the binaural Amber Rubath album sounds gentler and more delicate from the iPad, but more forward and aggressive with the MacBook Air. It's quite maddening. Would be great if the AP1 worked with 192k from the iPad though!

 
I'm streaming them using the iTunes Sharing feature. Would be fantastic if I can get this working. Apple has likely done a silent update of this feature to allow this, but the AP1 doesn't like the output.

I got my AP1 today...
I enjoy use a remote to control my music and bypass my actual preamp using the volume control from the ap1.

Congrats.. Let us know what you think of the sound....

I upgraded from AP2 so I know what I have. Battery is a must IMO ... My preamp powered with supply or battery, it's the same thing. Each time I put a battery somewhere, it's a great improvement.
 
Purepower is plug and forget. It's not cheap but the device is well designed. It's possible to bring things better with stock AP2 when cleaning usb power. I was using hub + battery pack was very convincing. Having to manage battery charged ... not very practical ... it's work for a time ... but after need to the true device.
 
Purepower give even better sound than outside usb battery, more isolation, DC-DC noisy chip out the way ...
 
AP2 to AP1 ... very fen to have all those features. The biggest difference was to bypass my preamp using only dac on the amp using ap1 to control the volume. Have a remote in my hand to adjust the volume, mute, restart song, next, previous ... very convenient. I still need to use my computer but both together is very fun.
 
Now I need to figure if I can stack 50 foots of USB without impact the sound. I will test my hub + battery to see if that affect the sound of AP1 + purepower (probably not signifiant).

Lookie at what arrived in the mail today.
 

 
Will be posting impressions after a week or two of a/bing.

Good to see you on here Caution. I'm glad everything made it to you so quickly. I look forward to your impressions. That being said, I think my old AP2/PP is gonna kick your AP2's --- lol.

Finally pulled the trigger today...on Schiit DAC & amp to set up new laptop system:
 
FLAC/Foobar/JPLAY 4.3 > Wireworld Ultraviolet > AP2/AQVOX > Black Cat Silver Star > Mini-Circuits HAT-10dB > Gungnir > Pyst XLR > Mjolnir > Moon Audio Blue Dragon 4-pin XLR > HE-500.
 
First time running balanced - impressions to follow.

For anyone who finds the AP2 aggressive and grainy, I highly recommend enabling SPDIF bit 28  (thanks to HumanMedia from SNA for bringing this setting to my attention).  For AudioGD Reference 7.1 it won't work as the DIR9001 wont accept the clock level.  My NFB7.32 works fine though, WM8805 might be more chance of working as well.
 
Instructions can be found in the new manual, as well as in the new firmware package.

The WM8805 works with it but indeed, the DIR9001 wont work with bit 28 set.

(woot! post 1000)

I ditched JPLAY and 192 worked...I read somewhere else that AP & JPLAY may not play well together.
Anyway, based upon my previous post, do the settings look okay?
 
Even though I've only had a few hours on it, I'm very pleased with the overall sound I'm getting. Not (over) bright at all, which was my biggest fear.
With more time I'll do some critical listening - but right now I'm enjoying the music!

The WM8805 works with it but indeed, the DIR9001 wont work with bit 28 set.

 
Really?
 
My RE-7S (DIR9001) locks on all supported sample rates (44,1 KHz; 48 KHz; 88,2 KHz; 96 KHz) with ap2 on firmware 1.27 with all bits enabled (24-27 "sample rate" bits enabled + bit 28 "level I clock" enabled).
 
Strange.

 

[ljhodad]

Well good news, a few days after tossing JPLAY 5, 5b comes out and it works!  I now know I prefer the sound of 5b ASIO (KS, Beach, Native, 256 Samples) vs. just Audiophilleo WASAPI (event). The bass sound fuller, tight and not veiled, while the treble extends without sibilance. Sounds more real to me than before. The song that convinced me was Ry Cooder's Ganges Delta Blues from A Meeting by the River 88.2/24. End-game good now.

The Master 7 might have a different set-up. Oh well. The whole S/PDIF bit settings are new to us. Might have to investigate more.

 

[HumanMedia]

Aren't bits 24-27 set to on by default?
and bit 28 is off by default.
So unless you want to block certain sampling rates, bits 24-27 should be left alone anyway.
not sure, but I think this is the case.
