Geek Pulse: Geek desktop DAC/AMP by Light Harmonics

[eliwankenobi]

I for one don't count on it. Nothing against LH Labs. It's just the reality! I certainly hope they surprise me as I should be one of the firsts to back up the Pulse

With the announcement of the new Apple remote, what happens with that functionality of the Pulse now? Is the new remote going to work? Or will the old type continue to be sold?

Not sure about the new one, but I have the feeling the old ones will be available on eBay for a long time...

Did they ever add functionality to it? Last I checked it was for like volume only, no switching songs or something (I remember thinking it was kinda useless)

The only interaction the Apple Remote has ever had with the Pulse has been volume control, and access to the menus for changing settings.

So if the 1G sounds limp, thin, and boring, how does a printer cable sound?

Fuuuuuuu........
I tried out the LH Labs Demo program with the LightSpeed 10G Split cable. This cable destroys the 1G cable (which sounds the same as my printer cable).

Audirvana Plus + LightSpeed 10G Split + LPS4 + Pulse X Infinity + SRS-2170
Holy smokes this system reminds me a lot of the SR-009/Blue Hawaii combo I heard. This doesn't sound like a typical Delta-Sigma DAC system any more either.

What sorcery is this?

split usb cable = r2r sound?  I'm skeptical.  do you have the 2g cable too?  is it an improvement over that?  using any wyrd/regen type things?

It adds instrument separation, layering, and solidified imaging on my system, which I've generally heard more on R-2R DACs than Delta-Sigma ones. The dynamic range seems to increase a bit too, having more bass impact and a less grainy-sounding treble. It's kind of hard to describe other than that...and if you're reading this, you'll see that I say basically the same thing for the LPS versus switching power supply except I think this difference is more dramatic maybe. I'll have to do some more testing later when I get the chance.

That and it seems to reduce the glare, or what of it exists, of the typical ESS Sabre DACs. Not that I think their implementation of the AQ2M sounds glarey or anything, just that it sounds much smoother overall when using the 10G split cable versus the one 1G cable.

I don't have 2G cable with me unfortunately. I backed one and should receive another from the THD perk. I also joined the 2G demo program but only 1 demo product can be checked out at a time.


I don't have experience with regenerators/reclockers.

It'll be available in Apple stores and online for a long time still. It's used with the entry level AppleTV, MacBooks, iMacs... I don't see that remote going anywhere.

There's no reason to get the new remote over the older one, save the few extra bucks and spend that on some music.

New Remote should work but bit a bit overly excessive and useless. The remote is listed to have IR in it but the new updates to it mean it will have a lot of things that simply will not be used when controlling your Pulse unit. Maybe that can change in a firmware update to the front panel on the C2 models but otherwise its going to stay exactly like this.

I've got the 10G split and also using the Regen, and the addition of each piece of the system has been a noticeable upgrade.

10G is the best USB I have used. Very noticeable improvement in soundstage depth and width.

The old one wont go away soon that's for sure

Well, after 4 moths travelling abroad yesterday I was back home and finally could unbox my Pulse Infinity, Yay!
I must confess, after all those LH delays the new product excitement was gone.
Left pulse connected on LPS overnight and tried it this morning with my picky 9 year old fellow K701, I must confess as well it just put an big smile on my face. This is one of the best pairings of K701 Ive heard. The pulse drives the K701 effortless even in low volumes lots of details, space, the bass hits hard! Thumbs up! 

Moved to the TH900, would it put an double smile on my face? To my surprise, not.. TH900 and pulse did not get well, TH900 lost its beautiful details that I have when plugged directly into ZX2, It was kind muffled.. maybe I need to test with another gain+digital filter combo.
 
Is it worth the wait + the price paid? I think not,  As a R2R freak I would probably go with Yggy/Rag combo.
 
Lets back to the music!

I have the 2G and 1G connected to my system, and that was one of the first things Ive tried... no difference at all.
As an engineer Im not a believer that a high end (AKA 10G) differs from a good one.
To avoid self biasing, one day I really would like to be part of a double-blind usb cables trial!
