How and who makes these classifications

I want to buy a good 2-Channel Class A amp under $1000...but the cheaper the better...I am a poor poor student

Abstract7 made the important distinction between Class A operation and Stereophile's rating system. If you're talking about the Stereophile system, that is defined at the beginning of the April and Oct. component rating issues, and of course in this case, Stereophile defines the classes.

I can strongly recommend the McCormack DNA-0.5 and DNA-1 amps. They operate in A/B mode-- this means that the first few watts are biased into pure class A output. Class A output means that the amp is running "wide open" with only one regulation device. These are both Stereophile Class B amps. The Deluxe models are slightly better. The .5 can be found used for $600-700., and the DNA-1 about $1000. A nice aspect of the McCormack amps is that Steve McCormack of SMc can up-grade them to standards that will easily meet or exceed Stereophile's Class A standards, as your budget allows.

I had a pair of DNA-2DXs up-graded to Revision A, and they are fantastic with great bass and a tube-like mid-range and treble. Good Luck. Craig
You can never have too much power in an amplifier. Simple rule to follow: If the first 5 watts are very good, why wouldn't the next 195 be just as good? As far as a recommendation is concerned, I wouldn't sweat "Stereofool" lists too much. Those listings have entirely too much to do with advertising dollars and not enough to do with system synergy.
Most of the amps recommended to you on the other posts are very good. However, check out the Muse Model 160 or any of their amps for that matter. You can get em' used for a song on Audiogon and ironically, the 160 was a Stereofool class "B" contender with $$$ next to the listed price. Maybe they didn't advertise as much as they needed to get that coveted "A" rating. Maybe the amp was too cheap. Who knows? That aside, I used to own it and it drove a few great pairs of speakers that have come and gone in my system, and drove them well. Since you're in college and space is probably a factor, any of their amps will drive the better monitor speakers out there exceptionally well.
Good luck in school and best wishes!
Class A amplifiers and Stereophile class A rated components are not the same thing.A class A amp runs hot and inefficient but sounds as loud as a class AB with double the rated watts.A Stereophile class A rated component is just a rating system for a very popular magazine which can be taken with a grain of salt.They are heavily influenced by advertising dollars. Listen for yourself or talk to some audiophiles that have been around for awhile.But all that aside you can get a very nice class A amp on the used market which is also rated as class A by Stereophile for around a grand.The very popular Pass Labs Aleph 3 solid state.
I couldn't believe I actually got so many responses. For those who wanted the sensitivity of my speakers...i dont know...i'll check the measurements ...but they are home-made (by me) 3-way with a JM Labs Utopia 33WX woofer with a PHL 1220 Mid-Range and a Philips R8TP tweeter. I might add a Raven r3.1

So i Think I have decided on integrated for now.
How are Cambridge audio or Audiosource??
I think i have zeroed in on either a creek 5350 or a musical fidelity a3 (integrated
For Cambridge Audio look for the discontinued A3i. It is superior to their current A500 and other offerings. The A3i was designed top to bottom by Michael Creek, so it's like getting a Creek at a big discount ($250 used). The A3i also comes with a decent moving magnet phono stage.

I use an A3i in a small system in my den/home office along with a pair of the original B&W CDM-1 speakers with MIT-T2 biwire cables; and a Stan Warren modified DVD player. Plus an Onkyo Integra Tuner and vintage Dual turntable.
