They look flimsy, better stick to the PLX2 3XXX series. I may be wrong but when it looks like a cat and weighs as much as one,it aint a lion.

Ask yourself mortal , do you have as much displacement as me ? The answer is no unless you have a Windmere fan sub.

yikes, looks like they are in the league of the crown xls series

BTW aurthur, it really doesn't matter if you get PLX, PLX2 or even 3XXX, the 2402's, 2502's and up have the same base design, they are all quality, lower end PLX amps aren't quite the same though.

They very close on the inside,where the beef resides. PLX/PLX2 are almost identical. The Super SPL is the PowerLight PL380.Loaded with even more goodness,of course it costs three times as much.

Much fuller than the fabled XTi1000

I looked at the GX before getting a deal on a 4month old RMX 1450. I wasn't thrilled about the cooling on the GX. In a closed cabinet it would intake it's own exhaust.
Input sensitivity about the same as other pro amps. RCA inputs are no advantage. I use a 1/4" TS to rca cable to the receiver. No hum. I forgot to turn the 1450 off the other evening and left it on full gain. Never heard a peep from it. No hum, no hiss, no fan noise, no clicks. Didn't realize till next day when I saw the power light on. The 1450 weighs 40lbs but I only had to move it once.

The QSC RMX line is a great buy when it comes to subwoofer amps,the RMX 1450 is a very good value,as it the massive RMX5050.

Guess I should have specified the intended use being as a mains amp

an alternative to the EP2500 for those who are afraid of using 1/4" TS to F-RCA adapters

These amps are not bridgeable

Been using EP2500 for 2 yrs now for mains. Like QSC rmx series, no hum, no hiss and no clicks even at max gain. The source is Oppo 980H with a built-in decent DSP. This combo sounds good on M-Audio high end studio monitors

Your driving monitors with an EP2500?

I'd use an A500 for that, no fans and bridgeable output, of course, the output isn't quite as nice as the high end GX amps, but if your mains are 8 ohms, a bridged EP2500 is a great solution.

That is correct. These are 11 yr old passive monitors which sound so good that I decided to try the Berry Passive B2031P in another room. These babies sound wonderful too. I have a TrueRTA graph somewhere and was amazed to see the measurements. All the amps have low dB fans though.
On another note, recently I had queried about Sierra-1 and the manufacturer came back saying that their monitors are very well suited for EP2500, QSC and Tapcos. I guess it is obvious not to push them hard with these amps.

We are talking about torque rather than HorsePower with EP2500 and QSC RMX series.

Well they are great for a mains amp, I just never woulda though people would be using them on small bookshelf speakers. I am not sure why any speaker would be unsuited for an EP2500, they should work well with anything, unless you had a speaker that was less than two ohms or something. A bridged EP2500 can drive even the most capable mains, such as the LS9's or other high output speakers and down to the smallest of speakers. The issue becomes when it become impractical to drive your speakers with such a beefy amp. BTW, why do you need torque when driving those speakers?
