Hi Everyone,
 
I've listen to my Sony M10 + 2Stepdance (15V) + Grado M1 for two months, now I found there randomly (every abot 15 ~ 45 min) appears a very loud noisy shock for about 2 seconds. I am quite sure the problem is come from 2Stepdance. Does anybody know what is the cause of this problem, and the way to solve?
 
Thank you!
 
Best regards,

Do you live in Switzerland or use ethernet in your mains?

I can't believe I never thanked you for your power output math post Mike! It was really appreciated.


On a sadder note, does anyone know how/where I can get a replacement for that rubber/silicone o-ring thingy that is used on the volume pot for traction? I just noticed mine was missing, somehow

Try a hardware store. (If not, any decent scuba dive shop will have them.)

Ok that's what I was thinking (not the scuba shop, but there is actually one on my way). Thanks.

Any guesstimate as to what size?

Not really but you usually have to buy a set for a few dollars anyway. They stretch so you have some leeway.

Gotcha. That sounds good. Thanks.

OK, to rule out some suspects...
 
1) Have you heard this noise after an hour of listening with a freshly installed internal 9V battery?
 
I know that the Stepdance can start making funny noises when the voltage drops too low in a spent battery, but I've never heard of this happening when connected to an external PSU - which brings me to the next question (as I can't remember what you're running):
 
2) Are you using the Energizer XP8000 + Willy Cable WI15 to supply 15VDC to the 2Stepdance or are you using some sort of AC adapter?  
 
3) If it's an AC adapter, how many amps is it rated to deliver at 15V?   (You might not be getting enough current to the 2Stepdance.
 
I will await your reply, but please try a good long test with an internal 9V battery, first.
 
Thanks,
 
Mike

Mike,
 
You are always so kind, Thank you!
 
I'm using the 15V 2Stepdance system is exactly what you discovered, a very good improvment indeed!
 
During these two days I trying to figure out where the problem come from, but unfortunately (actually is fortunately) the noise disappear.
 
I believe it probably come from the bad contact of the power connection cable (the adaptor for Willy Cable WI15). I will keep monitor the status and report.
 
Thank you!

Hi Everyone,
 
I am trying to upgrade my M1 to Grado RS1i. I know many of you are using 2Stepdance (15V) to pair with RS1i.
 
I would like to know if 2Stepdance (15V) is good enough to push RS1i, or RS1i must pair with Grado RA1?
 
Thank you!

You're welcome, Airwater!

I've lived without mine for a few years now. It was a tad annoying at first, but I got used to it quickly.

I have a Grado Rs1 (not Rs1i). The quickstep is definitely good enough to drive my Rs1 properly. I've never tried the Grado amp though...

My Quickstep should be with me in a week. I have a question about rechargeable batteries. Would I be better with (A) Maha 9.6V 230mAh NiMh; or (B) iPower 9V (<9V?) 520mAh lithium?
 
My understanding is that (A) gives me higher power (and better sound?), but (B) lasts for longer in between charges?
 
Thanks in advance for any advice.

No 15volts is what you want , but 9 volts is more portable

I doubt you'll be able to hear so small an improvement in voltage offered by (A), but you would definitely appreciate the much greater play time offered by (B), which probably has a fully charged voltage of 8.4V.  
 
I would get (B).
