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.

The D5000's are easy to drive at 25 Ohms. I just want to make sure the Quickstep has good, powerful bass impact as I know the RSA amps are renowned for their powerful bass but don't want to add a warm amp to an already warm headphone.

Can anyone confirm whether this 15v power supply and adaptor would work with the Quickstep?

Adaptor: http://www.ebay.com.au/itm/1-x-5-5x2-1mm-Female-3-5x1-35mm-Male-Plug-DC-Power-Jack-converter-Cable-CCTV-/180904641816?pt=AU_Laptop_Accessories&hash=item2a1ec1c518#ht_3106wt_995

Power Supply: http://www.ebay.com.au/itm/Power-Supply-Adapter-Converter-100-240V-DC-15V-/200692766535?pt=AU_Travel_Acc&hash=item2eba389747&_uhb=1#ht_4028wt_782

The power supply is not regulated and therefore can not be used. I'll suggest you take a look on either RS Components or Element 14 Australia.

Would the adaptor work though?

It should. However, you could just get a regulated adapter that comes with the right tip.

You could also find one like this that comes with different plugs in various sizes:

That one looks ok. How do I know if the power supply is regulated?

I had a look at those websites but can't find a 15v power supply. Could you have a look for me and link me to one if you can find it? I'd rather get a 15v to a 12v as I want to give it as much juice as possible.

That won't work either. It is not regulated.

 

All regulated adapter will say it is regulated in the spec, since regulated adapter is better in quality and thus more expensive than typical adapter.

You need to understand that a 15V regulated is much harder to find than a 12V regulated and will cost you a lot more. A good 12V regulated is less than AU$20 but a 15V regulated can be twice as much, if not more.

 

This is the only one I find, but you need a tip adapter for it:

Thanks. Will there be a difference in sound quality between 12v and 15v? Is there a 12v one on that website?

15V will give you a bigger voltage swing, but for the most part, I don't think the difference is significant enough for most headphone you are going to use with a portable amp. Just search '12V regulated' and some will pop up.

Ok thanks. I have one off topic question since I have your attention - I have the Stoner Acoustics UD100 and was thinking of getting the ODAC, is it much of an upgrade in sound quality?

The only real upgrade from UD100 to ODAC is that the digital volume control on your PC will behave better (*no compression), and you get to play 24/96 bit music. Other that that, there isn't any sonic improvement that I know of.

thanks. Is there a DAC around $150 that is an upgrade from the UD100?

I don't know any, but I generally doesn't pay a lot of attention on DAC.
