While in concept the linear power supply makes sense, but how much of a difference does it make upon real [insert sound science only term here] listening tests?
Spending nearly as much money on a power supply as the amp itself makes little sense to me.
As mentioned, we don't even know the performance of the stock Pulse.
I was looking for a small footprint, high value device. So at roughly $350 for a 3W balanced amp with a high quality Sabre chipset from a company that makes a very good, high end DAC, I am set, regardless of how the other upgrades would impact the performance. I can appreciate what a good LPS can do, but no way does it fit into my current value system.
According to LH Labs: "Since Geek Pulse isn't USB powered (like Geek Out is), we'll make "Da Vinci magic" again with a quiet and proven super regulator that uses a large bank of capacitors, providing the best power supply in its class." So if that is really the case I don't see how the LPS would improve anything but maybe LH would care to explain.

No need for them to reply. They are simply responding to market demand.
There is a $399 power supply waiting for everyone who also uses $200+ cables on their $700+ headphones, and want the "best". Measurements and blind A/B testing be damned.

It should regulate the AC power on its own well enough with a good design, which I have no doubt they will provide.
The LPS is for people who think that isn't enough. It was requested, so they provided. It doesn't mean that it is needed, or if it will even be an audible difference in your setup. It may provide a boost for one person, while offering nothing for another.

LPS is a good thing to read about, not just in this case but to know what you're buying/how to upgrade what you've got, further down the road.
Some Dacs below $2K will have an LPS included, some will stick the wall wart in the chassis to make it look like they have an LPS. Your audio dollars will be better spent if you know which is which and why to care.
Fraggler put it well that at $299 it's a great value piece, as you add the upgrades you will get better audio but further away from the basic value. Also what cans are you going to be listening to this thing through and are they transparent enough to show the differences. I love my HD600s but they would probably fail in the transparency dept as far as some of these upgrades are concerned.
Here is some things to start reading about if you're interested, maybe not in this case but later
Quite a bit of budget-fi audio can be bumped up to mid-fi by tossing the crappy switching wall wart and feeding the unit a clean robust linear power supply.
Mid-fi dacs should already have a linearpower supply in the chassis or in a separate enclosure. I would not consider running a geek pulse from a wall wart. A good power supply is easy DIY. Even the cheap $25 units from amazon or parts express are noticeably better than a wall wart.
I will be building my own. For me the only reason to buy the LH power supply would be to have a matching enclosure, which is not importantt to me.
It has been my plan to build a LPS for the geek pulse from day one, weeks ago.
This is showing my ignorance, but when an amp has one of those big copper ring transformers in the case, is that considered a linear power supply? I actually haven't seen much mentioned about linear power supplies, usually they just say they have class A transformer instead of a walwart. But i guess most of the stuff I shopped for was cheap

Me too, although I had planned to pick up something like a Keces just to see where the Pulse could be pushed. Glad they offered one, as it ended up being cheaper and possibly better.
This sounds like a good intro DIY project though which is something I've been keeping an eye out for.
