That's a very generous offer, but I don't think I have a bad unit.  The hiss is not heard through the headphone audio system--rather the WI15 makes an audible hiss while operating that can be heard easily in a quiet room.  It's not loud, but it's there.
 
My setup is:
Apple Lossless
iMod
SXC ALO iMod cable
SD w/XP8000 & WI15
Audeze LCD-2
 
More to follow, gotta run . . . one final thought; a function generator, oscilloscope and high quality comparator would provide ample quantitative data for power source comparisons under various dynamic condition sets--essentially waveform distortion as a function of waveform, voltage source, and gain.
 
Ah, thanks Jan for the data on the LC filtration on the SD2, always a concern for non-battery voltage sources.
 
Cheers!

OK.  Sounds like you're onto something.  I guess the WI15 cable uses some kind of re-hiss-tor!  

 
I'm glad you're not hearing it in your headphones.

If we are entering the realm of acronyms, I suggest 2SD as more appropriate - or just stick with 2Stepdance.

How about SD²?

No. We should show Jan some deserved respect. It's the 2Stepdance, not the (ugh) Stepdance2.
 
Maybe ²SD...

I still like my original idea of calling it the QuickStep

Has anyone tried this as a power supply to the Stepdance? Sounds perfect for the Stepdance but not sure what its connector is like.

i think $360 is a lot to pay for an power adapter. i just received my 12 volt (switching) power adapter from digikey (http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=T984-P7P-ND) base on violeta88 suggestions and it works well, i don't notice any white/gray noise in the background or anything.

As mentioned in a few posts, if you guys are after a quality supply? try searching for a Mascot Regulated Linear Supply. It does have variable voltages (max being 15v) but it's a linear supply for less than £40.
 
RS Components is where I got mine, product reference 224-3849

I use the Mascot 8713 to power my Stepdance.
It has stepless adjustable output voltage 5-15 VDC and is linear regulated.
It also have exchangeable output plugs.

OK I decided to stop using the Maxtron UD100 DC input as I can detect a bit of noise when using it.
 
I am all for the Energizer pack and actually bought one - just need to buy the regulator now... But the need to recharge it is kind of troublesome IMO.
 
Now these look high end - how much do they cost and anyone tried?

Can someone recommend a truly high-end audiophile grade 15V AC-DC linear voltage regulator where cost is not a concern? I know it may be overkill for the Stepdance but after listening to the Stepdance at 15V for a while with the LCD2, despite the noise, I am really mesmerized.

Stuff like that tends to be pretty expensive.  You might as well build your own power supply, save a little, not to mention the fun.

If you don't like having to recharge the XP8000 and are considering a desktop AC-powered PSU, try plugging in the charger for the XP8000.  If you don't hear any noise at the headphones, you're good to go.

That's the only 15-Volt PSU I've seen that I would describe as "a truly high-end audiophile grade 15V AC-DC linear" power supply.  If cost is no object, get this one and let us know what you think?
 
Short of that, I think this unit (from the link you provided) would work really well:
 
http://www.matsusada.com/dc/r4k-36/
 

 
Source: http://www.matsusada.com/dc/r4k-36/r4k-36.pdf
 
It's rated to handle loads up to 2A (more than enough current to handle the Stepdance or 2Stepdance, which draw less than 100 mA) and can be set for any DC voltage from 0 to 36 Volts.
 
Snap it up and let us know what you think!  Just be careful not to bump the voltage control knob when the Stepdance is connected.

Hi ! I've been using the XP8000/WI15/2Stepdance setup for about 2 weeks now & (knock on wood) I am experiening only "inky black silence" between notes playing or when my player is paused ! my current listening setup consists of the following : Hifiman HE-4 phones (JMoney earpadded) (I used the pads designed for the Denon hps: the HE-4s even look better & more precise soundimaging)
                                                                            Hifiman HM-602 player
                                                                            a Whiplash mini to mini cable (very short & heavy gauge wire, forget which model #)
                                                                             2Stepdance w/ the above mentioned power supply setup
                                                                             mostly Wav & few 44.1/16 flac files
Thank you, (Mike is it ?) for doing the "leg work" on the 15v power supply options, I am absolutely enjoying the musicallity of this setup. ( I thought I was hearing some noise as I was listening while typing this , but it turned out to be the external drive I use w/ my DVR across the room. I love the way my HE-4s sound ,but they're opened back after all)

 

[zilch0md]

Believe me, I know what you mean!   (Sorry, I couldn't resist!)
 
And, you're welcome.  I'm glad to hear you're pleased with the results.  
 
I might be wrong, but I think you're the first to use the new 2Stepdance with the XP8000/WI15 power source.  Congratulations!
 
Mike

How about that ! & here I thought that others were already using this power supply combo w/ their 2SDs. One of my biggest "peeves" is the playback time of my HM-602(maybe my only, for now). I figured a way around that by taking the 602 usb cable w/ me & using the "optimized" usb outlet of a ZAGG Sparq to power my player whenever it drops to 2 bars. My mission this week, is to find a better "carry bag" to arrange everything in & also carry my hps in when they're not in use! I've been using an LL Bean laptop bag,but I think I want something I can customize a bit more. ( I had a little chuckle when I stacked my player,amp & 2 power supplies together one day. It was definitely not going to fit in any pocket, but I could'nt care less. It was funny though)
