Will mention it to Seagate. I was looking to get a new tablet and considered the Kindle Fire HDX tablet. Was curious on the built in DAC + opamp that Amazon is using. Wanted to to see what the output impedance was, the various mA rating at a number of different headphone impedance ratings, voltage output swing possible, etc. As expected, Amazon wasn’t willing to divulge the info. I did ask them if they would implement DPS plugin to improve sound quality while watching movies or listening music. The customer rep said they would pass the request to Amazon’s engineering department. Hopefully you’ll hear from them.
Interesting question. With the DPS plugin running under Windows I would thought it needs a double conversion to work under Airplay through a music application. For example, my music player (Foobar 2000) has it’s audio output mixed through DPS plugin so I hear through the headphone jack. To make it work with the Apple TV, I would assume that Foobar 2000 would to implement the Airplay feature – which I don’t think it’s going to happen.
I haven’t tried it with iTunes 11. It might be interesting if the DPS plug-in works only with iTunes + Apple TV. Will have to get an ATV to try this out.
Would like to know if I have music stored in an external storage, that it’s either connected via an ad hoc wi-fi network or through the router – would possible to play the music files/playlists?
I’m thinking specifically external storage devices such as Seagate Wireless Plus / Corsair Voyager Air / Siilcon Power Sky Share H10, etc.
Each of these have dedicated apps to access the drive via an iDevice – but no DPS plugin support?…:(
Thanks for the support. Yes, I have now re-activated DPS plug-in and it’s working now under Windows 8.1
I didn’t know the procedure prior to up-grading from Windows 8.0 to Windows 8.1 and hence the problem with DPS plug-in. Lesson learned, I’ll be more cautious the next time Microsoft asks for a major up-grade.
I’ve got 3rd generation iPad with iOS 6 and have hesitated the up-grade until the bugs have been worked out. Think I’ll wait until the bugs have been worked out before upgrading to iOS 7.xx
For those brave and willing enough to work through the bugs – I tip my hat to you guys.
Suggest the development team to include Kindle Fire device support. I’ve somewhere that Amazon has sold a few million Kindle devices and DPS 2.0 would be a nice feature to differentiate it among the “me too” tablet crowd – cough, cough, Google, Asus, Samsung…:)
Would like to know if the development team is thinking about reaching out to Amazon with it’s walled garden approach of Fire OS 3.0 “Mojito”. Concept looks similar to Apple’s iTunes.
When playing 24bit/96kHz FLAC files through direct streaming using either primary sound driver or speakers (Digital Power Station) the ‘B’ button does work.
I also played pink noise to see if there’s any SPL difference between ‘B’ button and no-‘B’engaged. Surprised that the meter doesn’t recognize the sound difference that I’m currently hearing with my ears. Using C weighting average with a digital sound meter from Minolta.
I haven’t tried higher sample rate music. Would need to purchase them and test it out.
Something funny happened when typing in item (3) in my previous report. Let me type it again.
(3) While playing music there’s an annoying pause/click/pop every time I start an application under Windows 8 64bit. Don’t know how to get rid of this. Sometimes this annoying pause/pop/click happens when I switch between active applications. Using Chrome, Foobar2000 and iTunes (have the latest version for tests.
On Foobar2000, I’m now using the direct stream. Selecting either (a) primary sound driver or (b) speakers (Digital Power Station) works with DPS plug-in. The ‘B’ button works and there’s an impact to the sound.
<span style=”font-size: 13px; line-height: 19px;”>When selecting direct stream using headphones (high definition output device) there is music coming out but the DPS plug-in doesn’t work. In this case selecting/de-selecting the ‘B’button has no impact to the sound. I believe Foobar2000 is bypassing the DPS plug-in. </span>
I don’t have a sound card and using the built-in DAC on the motherboard. In this case it’s the Realtek ALC888 . It supports 192kHz sampling rate. The virtual driver for DPS plug-in is locked into 44.1kHz, maybe this is problem?
Just to report in further issues with Windows 8 64bit and Foobar2000 v1.2.9.
(1) With KS output, doesn’t work at all and is broken. Suspect KS output only works with an external USB device as I got it working on the work PC + USB DAC and without DPS plug-in.

Appreciate the feedback and yes, I’m trying various city profiles. Have currently settled on Phoenix as the best sounding to my ears. Seems to go well with both the S2 and ATM-CKM500 IEMs.
Using Windows 8 Pro with 64bit version.
(1) I’m having issues with Foobar v1.2.9 selecting output device as KS:Digitial Power Station. It causes Foobar to have an error on the output. Only way around is to switch the output to DS: Speakers (Digital Power Station).
(2) When I try to adjust the speaker properties for the high definition audio device under the advance settings, the default format cannot go above 2 channel, 24 bit, 48000 Hz. I have some high resolution recordings in 24bit/96kHz that I’d like to hear, but DPS crashes when this happens.
Appreciate any help.
I’d like to second the request for Philips Fidelo S2.
I have another IEM made by Audio Technica, model number ATH-CKM500. Would like to make a request for a profile of this.
