Ahh, fair enough! If I were ordering them new from RSA, I'd probably still go with the Intruder. $50 for a perfectly decent built-in dac I can use when watching movies on my laptop? Don't mind if I do!

That's what I told myself, 50$ it's hard to make a case for it. Please go watch a movie, I've already done that and it sounds thunderous wink.gif

Quickstep vs. Rendition 1 size comparison:

 

 

 

If I'm to build a rechargeable Quickstep, I think I have devised a plan. I can get 11.1V lipo cells AND a balanced charger for less than the price of ONE 520mah rechargeable 9V battery. I should be able to fit the Quickstep PCB and the lipo battery inside a case and then hook the battery up to the DC input port. The charging plug on the battery I'd solder to a 4-way connector on the back plate, possibly a 4-pin mini-xlr. The charging plug from the battery would then be used to make a cable from the balanced charger to the amp. End result: A Quickstep in a rectangular case with 20+ hours of battery life. Biggest problem will probably be getting the faceplates to look nice, but Schaeffer AG should be able to solve that I guess...

 

Project LipoStep! :D

Well, good luck on your project, I have a feeling like it is gonna end up nicely ;)

I think it's difficult to find an amp for DX50 that will make a substantial increase in SQ without sacrificing portability a bit.

 

The DX50 alone already has very good SQ. Heck, it can even drive my BeyerD T1 and still give pleasing SQ.

 

If I want to pair a separate amp to DX50 I don't want the added bulk of the usual suspects of portable amplifiers out there. There are only a few options for small/slim amps which in my opinion barely surpass if not just equal the power/quality output of the DX50 (some may be below it).

 

It's rather interesting if there exists a slim amp with exactly the same footprint as DX50. Plus a substantial SQ improvement with more power output to boot.

 

This is my dilemma with DX50.

Portaphile 627. Excellent except the battery life. 4 hours only.

You just can't win it all, you want small and yet not smaller than the DX50 which when multiplied by two is too big. I have a combo that Soren hates lmao but when you hold it in your hand, the amp fits nicely in the palm of it while the DX50 side is nicely nested in it so to me that is the ultimum  portability. If you do not want bulk, then no amps that is probably the best advice you are going to get else go pick a Pico Slim and deal with the inverted pyramid issue (really though this isn't the Pyramid of Egypt). Once you will travel with it, you'll forget that shape very quickly. Now forget about the IC, it was not built for this combo so I made the best out of it but will eventually shorten the length and use shorted plugs. Also, replace the elastic band with Velcro if that suits your fancy.

 

By the way that shape is exactly how you hand looks like holding an object, why do you think the bowls are rounded at the edge, because you can wrap your hands around it, not with an unnatural square shape. :wink_face:

 

As far as the SQ improvement, that is personal and you may hear things I don't so I leave it up to you to find out.

Long live LipoStep!!! Soren keep us in the loop with your amazing home brewed project. I think when you are done, call Jan and show him what you have done, he might change the shape of his amp in a near future, maybe not. ;)

 

While you are at it, change those electro caps for some SuperCaps instead, they act as battery charger and have quick release, they are expensive but your power delivery will be more static, they can really pack up a large amount of charges. Vinnie uses it in his AK mods, he does not call them SC but that amount is listed are the only ones that can deliver such large capacitance. Also the Wima caps are not the best ones to use, I would go with a Kemet instead, those pink caps. The Kemet are built precisely and are so stable they improve the SQ dramatically.

How did you guys get your hands on pico power. It seems not yet available on headamp website.

It is you go to select the Order tab menu on Justin's website, it will take you to the order page that has the Pico Power listed with the pricing.

 

Pick a nice Red one, I have the slim in red and it is a work of art, pretty to show around. Just be careful they are more visible and easier to pick pocket. :frown:

"Ships in 4-6 weeks" is a bit lame though.  It`s available on ebay now.  

 

Gawd - that raw polished aluminum looks amazing !

Go to the Pico Power discussion thread, Justin has shown some pics of how those enclosure are being built, this guys looks for perfection and it shows, they fit to the T. If I was showing you my Pico Slim you would find out that those were machined from the same aluminum block. You can only achieve this match with strict low tolerance for misfit. Last time I checked he has changed his US enclosure maker and the results are just astounding. It is a nice amp to parade around, I also like the faux letter case which is nicer than anything that sells out there and it is included with the amp. There is no paint on the amp but it is anodized so last forever and looks beautiful. It might not be 4-6 weeks depending if he had some in stock, I gather that the black and silver would be the most common. I would drop a PM to see how long you would have to wait for a specific one. I did not wait 4 to 6 weeks for mine but again, it isn't the PP.

 

Ebay as you mentioned is another option but you are dealing with a company selling HeadAmp goods which probably does not matter because you would get the warranty through Justin's business anyway which is a 3 year coverage.

It is worth the wait, the end result is an amp that you want to keep for years so what's a few weeks? :)

 They seem to have a business relationship with HeadAmp, they claim to be their authorized dealer in Japan.
