2) This amp is a wonderful value for the price and puts out all the power it is rated for by IASCA standards (50x2) and more. The amp was used to power my components on it's own and is now on my horns. It is an extremely accurate amp at a great price. The crossover control is wonderful and flexible enough for what I needed. The inside of the amp is beautifully laid out and shows that there was time and worksmanship put into this product. The only part that would possibly stray someone away from this is the input sensitivity only going up to 2.5 volts. This is not even remotely a problem in most cases though. I would highly recommend this product to anybody. -Joe 02-17-01

3) My first look at the Arc 2050 was "Wow, it looks just like my 2100 only smaller"!Okay, that was a little blunt, but I'm really impressed with what this little amp does.It's pretty efficient for it's size, and I think it does it's rated power quite well.I'm sure it does it's 50 X 2 easily, a fair amount of power to a set of efficient components.I am using this on my components, but I feel this amp REALLY pushes when bridged to a sub (or two).I tossed this amp on a few different set ups including a couple of Diamonplate Pioneers and the usual JL 10 (W1 or W0 depending).I don't think the Pioneers could handle much more than this amp pushed them, and the JL was pushing very hard off of this one amp. This amp pushes an EASY 200 watts, more like 250 watts when bridged, and the amp only got a little warm to the touch, not more than leaving it in the sun for 5 minutes.The performance of this amp is impressive, but I really like the features on the Arc line up.All the power and speaker connections are on one side and clearly labeled as they should be, but the other side of connectors is so beautifully laid out, it's hard to not notice them!The layout is great, making all adjustments quite painless (with the exception of a slightly stiff gain knob, but that helps unwanted turning of the knob while driving), with the crossover points and all switches being easily accessible.Overall, I love the clean look of this amp and it's ease of use.-Andy

4) I've been running two 2050s for the last two months. These are awesome amps! Superbly engineered and constructed. Tremendously clean, just hit pause when your playing a CD to interrupt the signal and listen for background hiss or noise, there is none! I have one 2050 powering a single SVC 4 ohm Image Dynamics IDQ10 sub and it rocks. Excellent amp for this musical sub. I have the bass boost off too, because otherwise it would shake the whole neighborhood. Sure is amazing considering the old MB 300E it's in is known for not getting bass through to the passenger compartment. Amazing amp. According to the birthsheet, it's putting out 220 watts, 4 ohm mono, at 13.2 volts and .03 THD. At .05 THD it's delivering 280 watts. You'll notice most amp manufacturers only list the .05 THD number, their amps may not be clean enough to even get to .03. Also, it's measured at 13.2 volts, I've seen a lot of amp specs where they list voltage at 14.4. It's much better to get the power at a lower voltage and lower THD, makes for a much cleaner, louder amp. The other 2050 is powering a set of hybrid MB Quart Referenz 3-ways. The 2050 is fantastic for 2-way components, and adequate for 3-ways, but I'm bumping up to a 2100 for these 3-ways. Nothing wrong with the 2050 at all, the 3-ways just barely start to distort at indecently loud volume levels, so I figure the answer is, as always for everything, more power! The fact that the 2050 drives these 3-ways as well as it does is a tribute to Arc's engineering and conservative rating system. Great amps, great price, great value. I could not be happier.-Gebhard 7-4-01
