Meier Audio Quickstep (also Stepdance and 2Stepdance) Discussion and Impressions Thread - Page 175

post #2611 of 2775
Thanks, Mike.

I just found that the local rs online sells Mascot 15v regulated linear power supply (http://singapore.rs-online.com/web/p/products/224-3849/?origin=PSF_430702|QVBasket%20Summary-LL). Looks like it is a better choice than the switch mode except the output plug is 2.1mm. Do you know whether 2.1mm is outside dimension or inside dimension? Can JDS Lab Slip-on 3.5mm Barrel Adapter fit this plug? I don't have any experience with tips. T_T

It is probably a 5.5mm outside diameter x 2.1mm inside diameter plug. You will need to do some soldering -or- find an adapter to step down to 3.5mm (O.D.) x 1.30 mm (I.D.) plug, as required by your 2Stepdance.

Send a PM to precsmo and ask him where he got his adapter.

But I suspect it's also a "switch-mode regulated" PSU rather than the more desirable, "linear regulated" PSU.

Some switch-mode PSUs can cause a hum or buzzing sound with some audio gear, and even though Jan Meier recommends linear regulated PSUs, several people in this thread are using less expensive switch-mode regulated PSUs with their Meier portable amps, and are still enjoying a black noise floor. You'll just have to test it to know for sure, but the odds are very high that it will be fine.

By the way, You might want to put a piece of tape over the voltage selector to make sure that it stays set to 15V, and make sure the connector is polarized to supply 15V+ at the tip, with 15V- at the ring (or barrel of the connector).

Jan did once say that because linear power supplies are so hard to find, there is more filtering in the Quickstep than the Stepdance to deal with noise from switching supplies.

That's good news.  :-)

Good to hear this I have bought regulated wall wart PSU and people still says I need linear regulated I want to use it for a station reason just while I'm working in front of my computer at home.

Too lazy to send a pm to precsmo. :-p

Does JDS Lab Slip-on 3.5mm Barrel Adapter fit 2stepdance? 1.35mm is just 0.05mm bigger, but will it be too tight to fit into the 1.3mm Jack plug?
post #2618 of 2775
Yes, it works fine. Can you order that from your location?

Should be good.

Hi, Mike.

I have to order JDS Lab Slip-on 3.5mm Barrel Adapter from its website. I can get Mascot from local rs online.

Love 2stepdance. It is the best amp I ever used!

Is the only difference between the 2step and quickstep the upgraded rf shielding and rugged jacks? Do they sound identical?

Pretty much. It's otherwise essentially the same amp.

post #2624 of 2775

awesome, might pick up a 2step to pair with the dx50 then :D

Hello

 

Anybody has idea how does Quickstep compare to the old head-fi version of Meier's desktop amp? I think it was called corda headfive.

 

Cheers
