Not familiar with these brands but by the looks of their specs, they're most likely professional amps. They seem to have good performance features that can drive low impedance loads continuously. But I can dispense with their bridgable features as they can't even double their power rating at half the load. They don't even have ratings for 2 ohm loads which is often given in bridgable power amps and tells you how dynamic they can be even when brdiged.

Have your tried listening to them? I suspect they have high distortion levels at rated output but should be fine for home use at a fraction of their power rating. I am always wary about amps with specs that skirt FTC or EIA specification standards. Nothing about THD or S/N ratio. Nothing about the frequency bandwidth where the power is available, not even frequency response. No damping factor figures as well. Amp makers who can't give those figures are either sloppy or are ashamed to show them. Either way, it's a hint not to expect a lot from them. IF either of them are priced below 5T, that's good enough.

But maybe you have them, just didn't post.

yes, kOLIN made...a china job for sure......but hey, 200 watts in a home setting and less than 5k, what more can one ask....

surely this amp will not be choosy when it comes to speakers, and there is absolutely no reason for anyone to let it clipp....

ghomer · « **Reply #4 on:** Dec 09, 2009 at 09:11 AM »

mag sir AV amp ata pag'kakaintindi nyo dun..

less than 5k..

hehehe may maniniwala ba na 200wrms yun.. siguro yung baguhan pa sa baguhan.

av_phile1 · « **Reply #5 on:** Dec 09, 2009 at 09:40 AM »

Nope, read my post. I said its specs read like from a pro amp. Not AV amp.

And I said "If" 5T, then it's good. So that's hypothetical. I have no idea about the pricing. The specs don't tell much. Power isn't everything. But I figured if that's all I'd get, then I wouldn't mind spending 5T for one. So how much are they?

ghomer · « **Reply #6 on:** Dec 09, 2009 at 10:20 AM »

wla akong masyadong alam sa specs.. mahina ako dun.

ng'base ako sa mga gumamit at nakagamit nah.. siguro kung pro amp 200wrms malamang na 12k up ang range nun depende pa sa brand.

2 klase china amp

>china bangketa
at
>china factory made.. kung baga china na nga may peke pa, and that's china bangketa..

best way nalang dito is to find out san yung mga trusted dealers nila..sa kanila nakasalalay ang tiwala ng buyer nila.. pag' PEKE, sira sila.. pag'ORIG, babalikan sila! tama??? para sa mga tight budget, china ang takbuhan.. "FACTORY MADE" kung may budget why not spending those, for branded amps, ryt.. sa feedback nalng siguro magbase wag na sa numero. sa mga gumamit at nakagamit.. sila mgpprove.. ryt..

but thank you sir.. atleat ngkaroon pa ako ng idea sa mag china amp.. and sa specs nito..

If I have 12T I'd check out the Behringer A500 which has reference-grade quality for a pro amp. It retails for 12T if they still have it at the behringer shop at Park Square or at Raon St. It's one of the pro amps that got excellent reviews. You may want to check it out online.

sir bigyan mqo ng brand ng power that has 200wrms..

11k budget kung meron pah.. hehehe

sana meron pah.. baka mag' K-2 nalng ako ng konzert.. not sure!

I agree. The Behringer A500 is more or less a clone of the QSC RMX850, with it's "flying rail" topology, it was built with one thing in mind - power. It's big brother and more powerful Behringer EP2500 is also a clone of the QSC RMX 1450.

The clones are a lot cheaper because of the parts quality, but if you play with them "nicely", they should last you a lifetime.

A500

Trivia: You will notice that the center tap of the symmetrical power supply filter caps is actually the positive speaker output and is completely isolated from the chassis, hence, "Flying Rail".

meron niyan sa Buy and Sell section sir. for specs and other details, ask mo si google.

Behringer A500 amplifier 138wpc x 2 or 440wpc x 1 at 8 ohms 1%

yan nakita kpng spec..

eto pa,,

one unit good for full range and/or subwoofers
PHP 10,000

Quote
138 watts @ 8 ohms @ 1000Hz @ 1.000% THD+N, both channels driven

120 watts @ 8 ohms @ 20Hz @ 0.030% THD+N, 1 channel driven

120 watts @ 8 ohms @ 1000Hz @ 0.025% THD+N, 1 channel driven

120 watts @ 8 ohms @ 20000Hz @ 0.045% THD+N, 1 channel driven

220 watts @ 4 ohms @ 1000Hz @ 1.000% THD+N, both channels driven

180 watts @ 4 ohms @ 20Hz @ 0.056% THD+N, 1 channel driven

180 watts @ 4 ohms @ 1000Hz @ 0.050% THD+N, 1 channel driven

180 watts @ 4 ohms @ 20000Hz @ 0.050% THD+N, 1 channel driven

when bridged for an 8 ohm load, it can produce a minimum of 360w with less than 1% THD (these are real RMS watts, not peak output)

Please remember this words " when God Created the World........................the rest are Made in China"

Anybody comments on your post either you agree or not be thankfull for it or else nobody will answer you, we are here to gather info...

Respect brother.........just my 5 cents
