Geek Pulse: Geek desktop DAC/AMP by Light Harmonics

[CanDude]

Pretty quiet in here while we play the waiting game. Are there any new case designs to share?

 
My idea for a backlit volume knob, mounting the LEDs on the faceplate behind the knob that reflects the light back on the faceplate:
 

 
And...
 
 
              ...then....
 
 
                                  ....hmm...
 
 
 
 
Oh, here they come:
 






 

 
The black ones seem to be most popular.

That rotary knob is similar to the ones used on Resonessence devices like the Concero HP and Invicta. Not sure if it'll serve LH well to use a knob that is so similar in design.

I like that check-mark in the designs of the bottom two CanDude, looks like it's off of a headphones FR graph

 

[Icenine2]

I like the RED!!

 

[walfredo]

Number 2 and 4 (top to bottom) look awesome.

 

[CanDude]

Adapted the scale to the real size (6.76" x 2.3"), sockets towards the bottom and four screws at the corners:
 

 
I made the volume knob big as this is the only control we have.
And I persist to use 17 volume LEDs, only 8 LEDs would look ridiculous.
I'm not sure about the bolts, black is probably better.

I feel lucky today.

Because whiling starting testing the Muse01 Amp, I found another goodies in the package.

Muses7001 from NRJ...

www.njr.com/products/press2013/MUSES7001.html

Silicon Carbide - Schottky Barrier Diode.... Zero switching off noise, they just announce two months ago...

This level of nice component, I would love to use it even in Da Vinci DAC.

And of course, if cost is reasonable, maybe we could use it in LPS4!! 

We use another kind of diode in Da Vinci, also zero switching off noise... but this one is made from the pure copper frame... 

Stay tuned.... It's getting more and more interesting...

 
Taken from a thread over at the Geek Temple. Dagnabit Larry, you finally got me to upgrade to the LPS4. Now I'm really hoping that the Muses7001 make it in.

Schottky Diodes are great; I've encountered them in optoelectronic spectroscopy applications --- always wondered how they could be applied to audio...

May I humbly say: I'm innocent! 
 
I'm glad to see that NJR finally address this issue: Good power, start from the rectify diode!

 

[AxelCloris]

Of course you're innocent, I'm just being American and passing the blame. I've been on the fence about the LPS4 for a while now and I figured "why not?" This will allow me to have the connections should I need them down the road. I'm sure I'll come across something that uses 12V power on my desk at some point. The 5V connection on the LPS4 is going to be powering my USB interface. Should I upgrade from my Scarlett 2i2 to something like the 18i6 then that will be able to use one of the 12V spots.

Just noticed today that this is open back up again.  I think I'll finally be joining the backers at the end of the month.  It will be Geekpulse X + Femto + upgraded amp for me.  I'd love to back the LPS4 as well but this is all my budget will allow for now, at least until tax refunds.  But if those new Muse rectifiers are added, I may still be willing to pay retail for it later on.  I think between that and the LPS4 transformer and the "super regulators" this could be a very impressive PS, even at retail.  Priced too high though, and it will start to cross into High Current battery supply territory, in which transformers, rectifiers, and regulators are irrelevant:

We'd love to have you join the Geek Force family! Hope you do decide to get the Pulse X.
 
You're not the only one who is saving a few products for retail. And after launch you'll probably find a used LPS more easily than a fully upgraded Pulse X. The Ingiegogo campain gets you a fully decked out unit for $747. Tax free and no shipping costs since you're in the US. Current MSRP estimate is $699 for the Pulse X and that's without the added items. Factor in any potential sales tax and shipping fees and they're pretty close. So now is definitely time to at least get the Pulse. The other items don't look to have any special bonus to the Indiegogo run aside from the savings. Get a Pulse now and get all accessories later if you want. I know I'd want to get the add-ons anyways so I went ahead and backed pretty much all of it.

Thanks, I'm looking forward to it.  Luckily, this time the campaign end AFTER I get paid and I'll have a larger than usual paycheck that I can expend for it.  After just missing the main campaign I ignored the thread for a bit and then came back to find it was up again so I was quite excited.  Looking to also preorder a Hifiman HE-560 when it's available as well so the balanced drive will come in handy.  
 
I love my Soloist as a headamp but if the balanced amp drives the Hifiman's well enough, I could even sell the Soloist also to recoup some cost.  I've already made a few posts at the Geekforce forum and look forward to following the progress to see how it turns out.  I figure worst case scenario, it just ends up being "worth the price", at best a great value.  I'm personally always searching for ways to squeeze more performance/value into my setup since I'm very much a "wine taste on a beer budget" type of person.

Just saw that they added 50 backers for the femto upgrade. Wasn't there earlier in the campaign. But count me in as one of those who can't hear the effects of jitter, so I'll put that money toward the LPS instead.

 

[AxelCloris]

Huh, I didn't realize they had a cap on the femto clocks. It makes sense, limited supply from Crystek and what not. Just hadn't noticed there was the counter. When did they add the cap?
