Ok thanks for clearing that one up. But is the XP8000 the best Battery pack for the Quickstep or are there others I can look out for?

 

[Armaegis]

It's the most well known one. You can probably find others by doing a search for laptop portable batteries/chargers.

I would buy it again, no question. It runs the Amp very powerful @ 12 volt and you can even get to 15 volt if needed. But that is only for high Ohm phones I believe.  It is very nice to be able to run my Stepdance for a whole week without bothering about drained batteries.

Any difference in sound compared to just plugging in wall adapter 12V for home use with IEM's?

12 Volts is 12 Volts, as long as the wall adapter is a linear power supply and not a switch-mode power supply.  Ideally, you want a regulated, linear power supply.   Switch-mode power supplies can generate noise.   A good wall 12V wall adpater will sound just as good as a 12V battery pack.

Thanks for your insight Mike.....Also the others who helped out...

OOh one more question ......How many milli amps......Ive found everything from 300 to 1000? Which one?

 

[zilch0md]

The Meier Audio portable amps cannot draw more than about 1A (1000 mA), but it's OK to use a power supply rated higher than that - 3A, for example.  
 
Just make sure the voltage is not more than 16V DC, regulated.  I know the manual and the screen printing at the rear of the Stepdance indicate a maximum of 15 Volts, but Jan Meier once posted to this thread that you can go as high as 16 Volts.  Generally speaking, the higher the input voltage, the better the sound quality.  
 
This is pretty much ideal, in my opinion, except that it might not be regulated:   
 
Enercell™ 15V/1000mA AC Adapter
 
Radio Shack Model # 273-332
 
(Currently $29.99)

You would also need their Adaptaplug H (for use with the Meier portable amp power jacks, that require a 3.5mm OD, 1.3mm ID barrel connector.)

Oops!   I just noticed via your profile that you're in Melbourne!  Oh well.  Hopefully you can find something at the right voltage and amperage, there.

Yeah, but an adapter may say 16V and output 16.25V which runs the risk of damaging the unit.  Better to go with 15V and have a bit of headroom. 

 
Shouldn't the aluminum electrolytic caps remove noise coming from switching power supplies?

That's why it is better to get a regulated adapter. They will tell you the +/- xx% so you'll know the tolerance.
 
Caps will smooth down ripples, but it also depends on how bad it is.

 

[cooperpwc]

Indeed one is only meant to use a regulated power supply with the Stepdance.

I'm still running this daily with my Stepdance: <http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_162996_-1> Onl outputs 500mA, though.
 
You have to get an adapter sleeve, though. I think Zilchm0d found a way to just purchase the right one instead of a set.

Hi, I'm interested in buying a Meier Quickstep but wanted to confirm it has good bass impact? I'm tossing up between this and the RSA Predator/Mustang - not sure they pair well with Denon D5000's due to their wrmer sound signature?

 

[zilch0md]

I've never heard the D5000, but as you've intimated, the RSA house sound is warm, where the Quickstep is spectacularly neutral. Bass impact will vary with the efficiency of your headphones and the supply voltage to the Quickstep (up to 15VDC). With IEMs or really efficient headphones, an increase in supply voltage (above the 9V internal battery), would likely make no audible difference. I really don't know how "hard" the D5000 is to drive, but the LCD-2, for example, really comes to life with more power - which translates to improved bass.
