Geek Pulse: Geek desktop DAC/AMP by Light Harmonics - Page 98

More than likely this change was brought about to simplify production by only needing to machine a single back piece for all 3 pulse models. But whatever the reason, it's an approved and welcomed change.

I thought Dragonfly would rid me of the need to use ODAC+E12, but it's just too strong.

Geek Out (all of them) is even more powerful.

The Pico could be a huge hit, beyond the small audiophile market.

 

We have an internal marketing meeting for this. And I agree with your inputs...

 

So there will be a new model in Geek Out product series....

 

Originally, we got Geek Out 1000mW   720mW  450mW... 

 

Now for IEM users, we will have Geek Out 100mW!

 

No new names, the number there is easy to remember.  

 

We build several prototypes in the lab, and result is promising. For IEM users, the criteria of headphone amp is different, so we will test it more....

 

Geek Out 100... Here you go!

That's good news! Thank you for taking the suggestions from users and making a more appropriate name. smily_headphones1.gif

Still hoping the X in balanced will have more output than the S...

How long for the Geek out 100? Can I swap my pre-order 450 for a 100?

Hi Larry

 

I see the X still has a maximum output of 7V in balanced - is this final? If so it means you must use balanced to get the same output level as the S has single ended.

Dream come true...

What's the ETA and the estimated price?

ETA will be soon... We are testing our final RC in labs.

 

We are looking for 3 beta testers as well, who is serious IEM users. 

 

After that, we will launch it. ;-)

Geek Pulse X will have max 7V in Balance, 3.5V in Single-ended headphone output. 

Geek Pulse S and Geek Pulse will have 7V in Single-ended headphone output. 

 

We could not change that due to the current design structure... ;-)

Obviously, I volunteer.

Check my profile for the IEM inventory. I also have Geek Out 1000 coming in.

This is like a dream come true, one for my laptop and another when I'm just city-roaming. 

I have a Geek Out 720 incoming. but I'd be more that happy to beta test for you. ;)

Thread Starter 

LH Geek Out has its own thread here -> http://www.head-fi.org/t/677263/light-harmonic-geek

Please direct your concerns regarding Geek Out 100 there.

 

Let's keep this thread for Geek Pulse to avoid confusion and overlaps.

 

Thanks Guyz!

Wonder how the survey beta test is going. I wasn't a part of it ;(

 Hi, guys

We are finalizing the integration of Geek Pulse enclosure and PCB boards. I need one good idea here.... I want to replace the SPDIF output (not input),the stretch goal in IGG campaign' with something better...

Reasons?

1. The back panel is really too crowded. And we just decided to add one RCA SPDIF input to Geek Pulse X, and one XRL AES/EBU input for Geek Pulse STD and S.... So if we squeeze another SPDIF output connector there.... It won't be good.

BTW, because I'm picky, every digital connectors needs to group together, so are these along connectors...

2. SPDIF output conversion IC will need to take the I2S signal inside signal path. We could either add a set of digital clock driver or other stuff to duplicate the digital I2S signal. The result is... We will add some jitter, although it won't be too much, should be 500fs or lower... But I still don't want to do it.

Since a lot of folks here buying Femto clock upgrade, and just like me, we are trying so hard to minimize potential jitter there. Adding a IC in the middle of signal chain for the SPDIF output that not every one will need seems not a good call.

Again, when we reach the stretch goal for SPDIF output. I really don't know in the end, this Geek Pulse will evolute into another much higher grade of DAC. In the beginning, add 500fs is not an issue, but now, it is my duty to let you guys know this is not a logical decision.

If any one could give me an idea that, we could add some other stuff inside Geek Pulse to compensate the SPDIF output and without giving up any performance. I would love to do that.

Well.... need your good idea here.

And yes, I'm ready to get some serious complains for the backers who originally plan to use Geek Pulse as USB to SPDIF convertor.

Warm regards,

Larry

 

Here's an update from Larry on the LHLabs forums. Linked below should you guys have ideas to help out.

Good that he didn't post that on April 1, but still kind of a bummer to those who wanted it as it was one of the stretch goals. I personally don't mind if it's taken out.
