This Gem Sound XP550 is rock solid. If you like the feel of real metal you get plenty of it here. Inside the unit the layout is spacious. The components are not squished together. This facilitates air flow from the two substantial fans along the sides. There is no shortage of internal fusing. This should avoid any serious damage to the units integrity in the event of mishap. Putting a spare fuse under the power cable insert was a nice touch from the factory. The instructions are a little vague for us novices. It took some searching on the net to make me comfortable with the hookup I have.My sound input is from the the Sub Mono Out jack of a Yamaha EMX 5000-12 mixer.(one very fine piece of equipment) The Mono Out is hooked to the left XLR input of the XP 550. The Peavy PV118 subwoofer is hooked via a 14 gauge wire with phono plugs to to the left output of the Gem Sound amp. The XP 550 is set to bridge position and the Yamaha LPF (low pass filter) switch is on. Keep in mind that this set up sends only the lowest frequencies to the PV 118 so if you really want to hear it thump you'll have to "pump up the volume". So far, I'm happy with the amp and let me tell you, my Grand Daughter and her friends can really make the windows shake.

I brought one of these amps on June 4 and it was in my hands by the 7th. The shipping of Musicians Friend is too good to be true.I had read all of the reviews so I was prepared for the odor from it being new. What I wasn't prepared for was it shutting down after 30 minutes of use. No clip lights or nothing until it shut down while I was playing at a mid level.I restarted it, and it played again for a few hours, but I kept it low and used another amp on the mains.I used it again at another show and this time the right channel went completely. So I called MF and they immediately gave me the ok to return it for a refund.It seemd to be a great value, but I'll stick to the known brands for now on.Luckily it was used just for extra speakers, but it wasn't as loud or as clear as a soundcraftmen's amp that's 15 years old and only rated at 300 per @ 4. This one is no way as powerful as its claimed to be.

This is a very powerful amplifier and surprisingly enough at this price, fan cooled. However, I do suspect from it's sound and price that it's digital which explains the unbelievably low price. It sounds great but, has that slight "plastic" sound that you get from the use of silicon chips..though I never popped one open to be sure. Kind of like a saran wrap shell around the sound but, this is easily countered with a good EQ. Overall, amazing amp for the money and ashame they've discontinuing them. I own 4 and probably would have added at least 1 more had they not put an end to their manufacturing. If they come back, grab them while you can!
I purchased this amp thinking it was going to be cheap quality and wouldn't work great, but I needed something cheap as this amp was only going to be used for practice sessions. Boy I was completely wrong, this amp is great, for anything, I would recommend 2 for gigs, but for our practice sessions this amp shoots out 300 watts on each side to our Yamaha mains. Good job Gem Sound!
I bought this amp to run our bands Main Speakers and we have used it with great success. It was a little noisey on one channel but not noticeable when a signal is running. It produces good power at 4 ohm load and we have gigged extensively.You can not go wrong at this price.
We use two of these for our small church and they work just fine. We run mains and monitors through them at 250wts at 8ohms and only need to be up about 3/4 of the way...push our music just fine and we don't do just the traditional music either!!!
I am using this amp to push four 15" Kustoms and it is adequate. I would say that the power ratings of the amp may be on the high side as the clip indicators will flash long before its rated output is reached. But overall considering the cash outlay it is a good buy, but it needs a "power" indicator. No regrets, I would purchse the amp again.
We bought this amp (Gem Sound XP-550 Power Amp) to run our monitors and wasnt sure what to expect because of the low price but it has performed GREAT. It has plenty of power and we have not had any distortion or problems with it. The handles on the front are nice for putting it in a rack or carrying. If you need power for a low price you cant go wrong with this amp!!!
I got this amp on scratch and dent for 110 bucks. I'm very surprised at how well it works. I use it to power 2 kustom dual 15 pa speakers rated at 300 watts program @ 4ohms. It gets plenty loud. Probably not powerful enough for subs but works well with my kustoms.
Purchased this amp for our monitor mix and it performs great. Plenty of power and so far not a bit of distortion. The handles on the front are nice for mounting in a rack or for carrying on its own. If this amp had a power on indicator it would be perfect. We are happy with the performance and the price cant be beat.
I purchased two of these from the scratch-n-dent section for my church, trying to be wise with the small amount we could spend. I was nervous because I had never heard of them but I thought we wouldn't be out much if they flopped. These things worked far beyond my expectations. The bridge mode had power to spare and they were very quiet to boot. I am going to pick up a couple for myself!
I have used this amp as a rental and back up unit for my DJ business. Have not had an issue yet. Very good sound.
