(More customer reviews)First off, there are TWO Rolls HA43 amps: The regular, and the "Pro" which is what this review is for. Be sure you're getting the Pro! It has more features, looks better, and costs the same or less than the regular version.
This is a great little headphone amp, especially to improve a PC's sound quality and volume. It's small, simple, has some great features, and the sound quality is excellent. I can't compare it to the "real" pro headphone amps out there that cost some serious cash, but I can say that my headphones (Sennheiser 280Pro and 555) both sound a lot better with this amp. The bass range on my 280's - which was really weak coming directly from my PC's audio - sounds much more deep, clean, and sharp.
FEATURES:
----------
-- Two INPUT types - You can use either the standard stereo RCA connectors, or 1/4" stereo TR (a large stereo headphone plug). The "non-Pro" HA43 has only a 1/4" TRS input jack.
-- Supports FOUR headphones, each with it's own individual volume slider. I had both my 280 and 555's plugged in and blasting away w/o a problem. Sound-quality-wise there's no difference between using 1 or 4 headphones.
-- Each of the 4 outputs has two stereo jacks to use: Either an older TRS 1/4" stereo jack, or the newer standard 3.5mm mini stereo jack that all headphones seem to have these days. The non-Pro HA43 amp only has 1/4" TRS output jacks.
-- It's small (about the size of two credit cards laid top to bottom). It also has four thick rubber feet, so there's no chance of scratching a typical desk or other surface.MORE INFO

I'd like to have a few small extra features like being able to wall-mount it, but I can't say there are any cons to this amp. Here's some extra info for you though:
-- There's no power switch so it's always on. But after 7 hours connected to my Kill-A-Watt meter, it still hadn't registered any power drain.
-- It's powered by a power brick. Oh well! There's an unobtrusive green LED on top of the amp to show you the thing is powered.
-- The volume sliders have only one detente, or "notch" at the half-way point to let you know how far it's been pushed. More would be nice, but oh well.
-- Be CAREFUL! Beyond the slider half-way point, this thing gets very LOUD. I mean "These go to 11" loud! I try to keep the slider at the half-way mark just to be safe with my ears, and that's plenty of power.
-- This amp probably isn't limited to headphones, but if you're using it for speakers, make sure your speakers are self-powered. I doubt this amp will support non-amplified speakers.
If you're a true audiophile who needs to have the absolute best sound available and you can spend the cash for that quality, this amp probably isn't for you. You probably have better headphones than me, and you probably aren't using the amp on your PC anyway.
I am extremely picky about my sound quality, but I can't yet justify spending $400-$2000 on a serious Pro headphone amp. With the headphones I have, though, this little amp does a GREAT job and is definitely worth the price.
