Intro
I first heard about Garage1217's Project Polaris (just "Polaris" from here on out, for the sake of brevity) directly from them back when I did a review of their Project Ember earlier this year. The Polaris was finally released back in late July, and once again Garage1217 was generous enough to provide a loaner review sample, which I was able to spend approximately 2 weeks with. Normally I would've preferred spending more time with the amp to get to know its intricacies better, but personal circumstances got in the way a bit and prevented me from doing further critical listening. So the proverbial "grains of salt" disclaimer certainly applies to this review, and my opinions could certainly change later given more listening time (if I decide to re-acquire the amp).
Operation, Functionality, & Handling
The Polaris was probably one of the most (if not THE most) physically compact AC-powered amps that I've ever seen (the dimensions are on Garage1217's Web site), and with Garage1217's trademark styling complete with the plexiglass top, it looked positively cool as well. And like the Project Ember before it, the Polaris sacrificed nothing in terms of functionality—in fact, it had even more functionality! With jumper-based settings to modify input attenuation, bandwidth, output resistance, and gain (and even to "turn off" the LED), the Polaris was by far also the most feature-packed amp that I've ever seen!
The plethora of customization options possible was certainly amazing but in actuality, I found myself not using most of them and only modified the output resistance to suit whichever headphones I was using—low R for my sensitive headphones; med R for the AKG K712. Much like in my experience with the Ember, I never needed (or wanted) to use high gain or high R for the AKG K712. I'd imagine high gain and high R to be useful primarily for those who have extremely inefficient or extra high-impedance headphones, like the HiFiMan HE-6 (83.5 dB/mW) or Beyerdynamic T1 (600 Ohms) as just two examples, respectively.
At first I had the input attenuation disabled, but I found that enabling it became helpful for my sensitive low-impedance headphones. The bandwidth settings were also cool for novelty, but because I wanted the most treble possible for all of my headphones, I just left it at high, since the lower settings reduced treble quantity. I'm sure that users with a greater variety of headphones would get much more use out of the customization options though, especially those who have a collection consisting of low-impedance efficient dynamic headphones, high-impedance inefficient dynamic headphones, and planar magnetic headphones.
Sonic Assessment
I'll start with an admission: I went into this review hoping that the Polaris would sonically hands-down beat the HeadAmp Gilmore Lite, because I really, really wanted to buy the Polaris for a few reasons, not the least of which was that I could buy it and sell the GL, and then come out ahead with some money left over. And I kinda just wanted a newer amp than the GL, which first came out in 2005. Unfortunately, the Polaris did not hands-down beat the GL—but when all is said and done, I'd say the two amps were nearly close to even and each had their clear pros & cons. The GL ended up as the obvious winner when it came to pure sonic speed (as in impulse response) & agility and overall clarity throughout the frequency spectrum, while the Polaris was much better at soundstaging & spatials and achieved a more natural-sounding mid-range as well. But since most people in 2014 probably don't own a Gilmore Lite anymore, any further comparisons to it would probably seem irrelevant, so I'll stop there with the GL comparison.
With the exception of the original Schiit Asgard, I haven't heard many of the under-$500 solid-state AC-powered amps in the market, especially recently, so I can't really say how the Polaris stacks up against any other currently available amps. But I've heard plenty of other solid-state AC-powered amps over the years, most of them more expensive than the Polaris (all the way up to the $3K USD HeadAmp GS-X MK2), and most recently the Micromega MyZic, which I had last year and retails for the same price, so I can sort of take a stab at how the Polaris might live up to most people's expectations.
I think most people who haven’t had a dedicated headphone amp before would be sufficiently impressed by the Polaris, and even those who’ve had more expensive amps might find it hard to dislike for its functional versatility. But before I get into its sound, I should also add that so many things depend on the source that you use, so I also recommend investing into a proper source, whether an external DAC for computer users, or a disc player for CD listeners—just don't connect this amp to a headphone jack, make sure it's plugged into something that has analog RCA outputs for best results.
Starting with its relative sonic flaws, I thought the Polaris lacked some clarity and speed/agility (which I have to reiterate, as that sorely stuck out compared to the Gilmore Lite), and it wasn't the best sonic match for the Audio-Technica AD2000 as a result. But the Polaris was also clearly the mostly superior amp in every other aspect—it was much more balanced-sounding, with a more filled-out mid-range that added significantly more presence to elements like bass guitars and male vocals, along with a more powerful bass in general. The GL had leaner, faster bass, with much more of a quick "spring" to it, but the Polaris had more bass depth & force, which made it more satisfying with electronic music in general. The Polaris also had a much more 3D-ish soundstage as it generally sounded "bigger" (in terms of spatials) from left to right and front to back. I found many instances on my recordings where the GL didn't catch any spatial cues at all, especially reverb, but were clearly heard on the Polaris.
Headphone Compatibility
There are primarily two factors when it comes to matching headphones with amps: (1) How will the headphones sound? (2) Will they be driven properly? With the Polaris' high power output capability, factor #2 is mostly irrelevant. It has enough power (current and voltage) for most dynamic-type headphones on the market, and I could tell that it was fully capable of manhandling my Audio-Technica AD2000 just as well as the HeadAmp Gilmore Lite, which was no small feat. (Not every amp I've had has properly driven the AD2000.)
The sonic matching is naturally much more tricky, and more nebulous too. I can only really say that I thought it wasn't a great match with the AD2000, as the AD2000 was slightly robbed of its awesome speed & agility. And the AKG K712 didn't sound quite as dynamic & expansive as I remembered it on the Project Ember—in fact, I'd be more inclined to recommend the Ember for K712 owners. Other than that, I can't think of any other sub-optimal headphone matchings.
Closing
There's really no better way that I can think of putting it: Garage1217's Polaris is the budget solid-state amp of the year, possibly of all time! It sounded great to me for the price and I can't think of a single reason why anyone would be dissatisfied with it. I'm sure some people would like to know how it compares to the Schiit Asgard 2, the other well-known American-made solid-state amp that happens to sell for the same price. I don't know how it compares. But I can definitively say that I'd rather own the Polaris when it has way more features and doesn't have anything that the Asgard 2 doesn't, and packs even more, including significantly more power output on tap in order to drive planar magnetic headphones. I have nothing against Schiit or the Asgard 2, but the Garage1217 amp just has more*, and looks cooler! (IMO)
The Polaris was simply an extremely capable amp. Actually an amazing amp, especially taking into account its relatively low cost ($250 USD) and factoring in everything else about it—all of its various functions, and the fact it's American-made (which may seem irrelevant for non-Americans, but for us Americans that's no small thing), and made by a business that provides excellent customer interaction. There's absolutely nothing bad that I can say about Garage1217!
* Well technically the Asgard 2 has the advantage of being a discrete amp that runs in Class A, while the Polaris uses an op-amp and runs in Class AB, but I'm betting that the majority of headphone listeners won't care about those difference and the consequences.

Personal Info
As an FYI to put the comments on "natural" sound into the proper context, I'm a trained violinist (learned via the Suzuki method for 12 years starting at age 6, then quit lessons at 18 and have been playing on and off since, and I'm 33 as of this writing) and have had an opportunity many times to play in a symphony or chamber orchestra, plus much smaller ensembles that have included quartets and duets with a pianist. I've attended classical-music concerts as well.
