Great at first but has longevity issues
By mark lampi
First off I consider myself an audiophile. I own 4 of these amps with 3 tri-amping my mains and 1 for surround. I've had these amps for probably 4 years now. These amps sound VERY clean and transparent and have good power. opening the hood reveals almost a completely dual mono design, HUGE torroid for power, nice filter cap section etc.BUT this amp has a serious design flaw and some other areas of concern. the main design flaw is in the speaker protection circuit, the circuit has a relay that the speaker lines pass through (which is pretty standard) BUT for some reason there is a large 5 to 10 watt resistor in series with the relay which gets EXTREMELY HOT. So hot in fact that over time it unsolders itself from the board! So eventually your speakers will begin cutting out and the protect light will show on the front of the amp. Trying to resolder the resistor is a job and a half. The amp is put together with the power plug soldered through the rear of chassis. I had to dremmel a notch through the rear and slide the wires out, then tear the entire amp down to get to the bad solder joint.I've had this happen on 2 of these now and I had almost no load on both of them. In fact, the first one to go was the amp on my tweeters which has never even been run high enough to show 1 bar of activity so you know I'm not abusing the amp or running it hot etc.The other problem with this amp is the pots (volume knobs) on the front of the amp go bad, also causing your speakers to crackle and go out. I will often notice a set of speakers not working and have to flick or turn the volume knob to get sound back.Also these amps have fans that are either on or off, they're not variable despite the specs making it sound that way, so the amp will wait until it gets good and hot, then fire up the fans at full speed and make all kinds of racket. To make matters worse, I have 2 amps that randomly fire up their fans for no reason at all. My midrange amp always statys stone cold but the fans will randomly turn on anyway. I've even taken the top off the amp and waited for the fans to kick in and felt the heat sinks and they're completely cold.I'm going to try my luck on a Behringer A500 as my replacement as these go out. I will not be buying anymore Samson servo amps.Edit - its now about 3 weeks later from the above review and a 3rd out of the 4 I own is beginning to go. the amp works but occasionally has an enormous POP that comes out of the right channel, sometimes it cracks and pops. as a test I disconnected the input so its just the amp and speaker (and good source of power of course) and still the occasional pops continue. They are SO loud, I'm AMAZED that my poor little 4" mid that this amp drives didn't blow completely out.Meanwhile I've replaced one of the samsons with an A500 and so far am very impressed. it wont be long now until all the servo 600s are gone and all new A500s are in!the servo 600s were fun while it lasted I guess...while the last one is still working I think I'll do some power/distortion tests on the samson vs behringer and post them here.

Pro amp for home stereo
By M. Pipkin
I wanted more power for my new MartinLogan Source speakers (to replace a 110 WPC Sony TA-N55ES). I looked at used audiophile amps, new Emotiva monoblocks, etc. but the more I looked the more I was tempted by inexpensive pro amps from Crown, QSC, Carvin, and Samson. These offer up to 300 WPC for as little as $300, some with switching power supplies that reduce weight to under 10 lbs (Crown), pure class B Operation, supposedly with no crossover notch (QSC), and ability to drive low impedance loads (the Source is nominally 5 Ohms and drops below 2 Ohms at 20 kHz). All are compact, rack mount units with fan cooling instead of external finned heat sinks and they are mostly ignored by what is left of the audiophile press; you can read about pro amps in home theater online forums, where there is no stigma attached to low cost.I didn't care about weight since this is for a home stereo, I don't need Speakon connectors, or XLR inputs, or built-in crossovers. All the pro amps appeared to have enough input sensitivity for my preamp (NAD 1600); some lacked RCA inputs but RCA to 6.3 mm adapters are available. I did have a slight (irrational) preference for class AB operation over D or B and I was concerned about fan noise, which seems to be an issue with QSC GX series amps in home use (some people install quieter fans, voiding the warranty). QSC has other lines they recommend for home use without modification.Samson is less well known but still has plenty of satisfied users, some of whom have experience with the other major brands, and I kept coming back to the Servo 600, which seems to be intended for use in a studio or fixed sound reinforcement setting (Samson has an SX line that seems geared to live performance). The Servo 600 has RCA inputs, operates in class AB and has a large conventional power supply. It also has fairly complete specs including power consumption at 1/8 and 1/3 of rated power output. I don't have all the comparable specs in front of me but the Servo 600 draws 1.3 Amps at 1/8 power, compared to 4.1 Amps for the QSC GX3 (the GX3 is 1/3 more powerful, a little over 1 dB). That means that played as loud as anyone is likely to want at home (allowing 9 dB headroom for peaks), the Servo 600 has to dissipate about 120 Watts as heat (28 Watts are going into the load) and the GX3 has to dissipate about 450 Watts as heat. So I expected the Samson to be cooler and quieter.I bought it, unpacked the cheap looking box (no damage), dragged away the Sony and shoved in the new amp. Plugged in the RCA inputs, screwed down the speaker cables, and connected the computer type power cable. Pressed the power button (no thumps) and turned the Samson gain controls to max. Absolutely no issues, and the fans are practically inaudible. It behaves exactly like any other power amp.Is it better than the Sony? It's 3 dB louder, but that's not dramatic. I may have been driving the Sony into clipping but I can't be sure because it has no meters. The Samson has LED's for each channel and it is not clipping at the highest levels I have used. I don't need more power than this, and personally I don't claim to hear differences between two amplifiers with flat response, low output impedance and >0.1 % distortion. I was hoping for more bass impact but I should have known better: that's a problem for this speaker in my particular room. I doubt any amp at any price would sound better (if you are not familiar with that controversy, the subjective differences that some reviewers report between similarly-spec'd amplifiers are unrepeatable when subjected to blinded comparisons).This much clean power, at this price, in a well-built, compact package merits five stars. I wanted to review the Servo 600 because there may be people trying to decide about using pro amps in a home system and my experience so far with the Samson is entirely positive.
