Strength:

My favorite thing about these units is that they provide a very neutral sound so it gives a necessary boost of power to any quality pre-amp you use. It won't color the sound so you get exactly what you want to hear from your base equipment. Regardless of what amp, receiver, pre-amp I throw at it I still get the characteristics of that equipment to focus on. Price vs performance and I have to say that I'm rather impressed. While not as cheap as other budget amps which may be smaller and provide slightly less power (I'm thinking about the Dayton audio amp 150), these hefty beasts don't disappoint when it comes to belting out the jams for slightly higher investment. However, compared to the big names at the same power rating I can say that the MSRP of $300-350 USD/unit is quite appealing. Still, I'm sure when compared side-by-side with a Bryston, Adcom, or modern Yamaha pieces these won't win any battles when it comes to specs or measured frequency response curves, but how many of us can throw $1-3k USD at a single amp?Honestly, how many of us can say that we hear the difference? You should be able to find these used for $150-250 USD. If I had to pick between this or an Adcom 5500 at the se price, I'm not sure that the Adcom would win. The fact that this is a true AB class amp while other budget amps tend to be class D only sweetens the deal for me. These run fairly cool and don't seem to need tons of space (though I always recommend plenty of breathing room). Easy to set up for stereo or dual mono, though the instructions on wiring as a monoblock arent that great. At 200wpc for stereo or 400 for mono you should have more than enough power to run any stereo setup.

Weakness:

I'm not a fan of the blue LEDs or the black face but these are small points to worry about. These units, when driven correctly and not fiddled with really crank out the juice. I have the OSD version of this unit that also uses two analog meters (left/right power output) but they don't seem to work on either of the units I am running (two amps for dual mono configuration). Then again, I'm not really cranking these suckers so maybe the power I am using is just negligible. Folks looking for a more compact build may not be too thrilled with ye weight of foot print of these beasts, but if you have the space they will give you what you're looking for.

I'm using the amp for more than 7 years.
I used to have really expensive amps in the past like Krell and later Bryston. I start using this amp as my main after moving to a smaller apartment (before i had it only for my center channel).

This amp is perfectly clear and creates a real great deep stage for stereo listening. I never had any kind of troubles or strange sounds. He can easily handle my B&W 803D having powerful lows and soft mid & trebles. If you find any of these amps grab them as soon as you can, it's a great tool for the money, comparing to way more expensive super "brands".

Strength:

price...
flexibility

Weakness:

none

great amp..warm sound. - very flexible...has 2 rca inputs, 1 rca out and a speaker level input (for when your receiver has no preamp outs) tremendous value. I love the sound...i just wished the main speaker input level was in the front as well...so i can adjust the input painlessles (since it is positioned in an entertainment center although there is a db level in the front also)

i have not experienced the hum/ground loop problems that some people report.

Strength:

Great sounding Amp at a wonderful price,heavy and well built with much power reserve.

Weakness:

Prone to ground noise,grounding Issues as older modelamp3..must use a ground eliminator adaptor

Great clean powerful amp.I am running the amp at 235 watts bi-wired(4 ohm output)a&b speaker output as opposed to 150 watt at 2 speaker a output. The difference Is outstanding with this setup. The reserve of power seems unmatched compared with my recievers output(120 wattsx7). I am running both fronts off the Audiosource and soundstage seems to be more open with the load taken off of my ht reciever leaving much off the burden off the ht reciever to only drive my center,rears and surround backs. Worth every penny giving that "seperates sound" of components.Also,the auto on feature works great..just be sure, like Its older model that this replaced, that you use a ground plug eliminator adapter,had alot of problems at first with amp noise and auto on,off feature. This solved all the Issues.
