His post definitely looked to be asking for desktop amps if you read the post that he quoted.

In the 650 thread, if you search through it, you'll find more than enough impressions from people with various amps.  In my experience, I prefer Jan's Concerto/Classic amp for the 650, over the Lyr or Mjolnir.  The Lyr had big space, big sound but I didn't like dealing with tubes and the cost of tube rolling and the noise floor.  The Mjolnir gave the 650's such an impactful bass punch that the headphones lost control of everything else and I didn't think that was a fit for me either.  The Concerto/Classic however made the 650 a bit more nimble and light, I would say neutral and polite sound, giving that overly lush sound of the 650 some breath and air.  This is in my experience, yours may differ completely but I think the price of the Concerto on the used forums is an absolute steal.  If you want a some place to start your journey for a desktop setup, I would try a stagedac/concerto combo.

Funny how these things go. I have not used my Quickstep much of late but suddenly it's back! The reason is that I got a Surface Pro 2 and the Fooobar > UD100 > Quickstep > Heaven VI combination is a nice portable surf and listen combo. 

 

The Quickstep is a great amp with IEMs.

Aye, saving mine as a desktop setup with incoming JH13's as well.

Tried the amp with the HD650's.  Really seemed to choke on them, power delivery wasn't enough even in high gain.  The K712's however were driven very well, using the xp8000 battery supply on low gain, and from memory almost as good as the classic.  The Dacport LX and Quickstep is quite a pairing.

Hey Mike, some of those battery packs can handle both usb and 17V output simultaneously right? You could lighten the load a little bit there...

post #2754 of 2790

I believe it's safe to power two devices simultaneously from a single XP8000, as long as you don't allow those two devices to have any other circuits in common...

 

I've TWICE killed the Sansa Clip+ by creating some kind of ground loop with an XP8000 and the Meier Stepance.

 

I was only trying to charge the first Sansa Clip+ from the 5V port while simultaneously powering the Stepdance from the 21V port (with 15V inline voltage regulator). Everything was fine, with both units receiving power simultaneously, until I closed the loop by connecting the Sansa Clip+ headphone out to the Stepdance line in with a mini-to-mini interconnect cable.  That immediately killed the Sansa Clip+ (with thankfully no damage to the Stepdance) - lights out - non-responsive.

 

I was convinced that it was just a fluke, so (being the slow learner that I am), I bought another Sansa Clip+, and fried it, too - again, it happened when I inserted the mini-to-mini interconnect between the Sansa Clip+ and the Stepance, having previously connected them both to their respective power jacks on the XP8000.

 

So...  I ordered a third Sansa Clip+.  Just like the first two... it works fine with the Stepdance, as long as I don't try to power them both from a single XP8000.  

 

:o

 

Now, I like to give everybody his very own battery!

Interesting... I wonder if the "grounds" are different depending which port you use on the XP8000. Might be worth measurig just to check.

 

I wonder if the active balanced ground topology in the Stepdance might also have something to do with it, since it isn't actually a "ground" either.

post #2756 of 2790
I'm still curious, too, but unwilling to conduct any more experiments.

Waiting for Jan to develop an atomic powered circuit and ps to give portable amps capability of giving us desktop sound from Orthos or...STAX!

 

*One can dream*

post #2758 of 2790

That's a surprising way to fry players.

 

There's something up with the grounding indeed, I also think.

post #2759 of 2790

I'm just glad I was frying Clips instead of Stepdances!  :D

post #2760 of 2790

Noticeable change of Quickstep and Dacport LX came in around before or after the 100 hour burn-in mark.  Bass filling out nicely, treble extended and polite, the depth and layering of soundstage (almost flat and lifeless out of the box) is natural and well done.  Limiting the K712 is its clarity, to which the HE-6 and other Orthos have spoiled me, but again, praising the desktop sound from a portable setup for low impedance cans.  Kudos to Jan and Centrance.  Certainly worthy midgame/endgame stuff.

 

Incoming are the HE-560's, can't wait to test.
