Power amps

[xsdata-kc]

looking at power amps and only want to spend about Au$500 max. I have had had some limited exp with Crown power amps and was checking out the XLS 402a a .. I only need max 200 watts per side at 8 ohms and this will more than do the job.. Does anyone have any other suggestions?? What do you use to power your monitors/pa speakers??

Happy NEw YEAR!!

Tis the most important question!!!!

As combining different Amps with Monitors will give vastly different results

Im afraid Im of no help here, I am using powered monitors, and just an old Technics A-Class amp for my Hi-Fi

I think the general rule is: Amp needs to be at least 1.5 times the power (in Watts) than the speakers, to allow for good headroom. Just keep that in mind.

for AU$500 I'd be looking at second hand pro hi-fi amp. I bought a 'studio amp' for AU$750 but after carful listening I prefer an old Luxman amp or the like.

Best thing would be to learn about amps, buy reading heaps of technical details of the design of amps. What is Class-A or Class B or differential and negative feedback?

Good luck.

I've got the RA300 at home and it is fantastic. I had it hooked up to a pair of Alesis Monitor Twos and it was the best sound I have ever heard out of a home setup.

Note where I say "I have heard"

maybe I haven't heard the best out there but I doubt you'd be dissapointed if you got the amp.
