Just copped some nice acoustic solutions speakers for proper cheap and the plan is too hook them up to my laptop with a converter to play tunes/play guitar through a guitar link.
Now I just need an amplifier to power them as my laptop aint. Anybody got any ideas on what to get? I'm a bit confused..
Saw these:
KAM KCA600 which offers 2x150w RMS for £109

PRO-480 Stereo Power Amplifier which offers 2x240 for a cheaper £85
http://www.amazon.co.uk/PRO-480-Stereo- ... 18&sr=1-14
(What is the difference here?)
..... Then I've been suggested a 'Pioneer A 109 Amplifier' by a mate, but these only offer 60w for £110

What's the difference between the power amps and the ones like the Pioneer? Anybody got good suggestions for a budget amp which will do the job?
Thanks alot

any amp that matches the wattage (2x150) and the OHM rating of your speakers will be fine
a stronger amp will work, but you risk blowing your speakers if you're not careful

Yeah, good point.
What's the difference between a power amplifier and an amplifier?
Like a pioneer 100w would cost £300-400 whilst a 100w Power Amp you can pickup for £50-70

i would presume a power amp is just part of a combination of a unit....

Power Amp is usually used to distinguish from Pre Amp. For your use, since it's simple, i'd recommend a 'stereo receiver', that way you can hook up multiple sources without needing a mixer.
i'd hit up a local pawn shop and snag one with an amp that has the same wattage (within say 10ish watts) and same ohm (very important) rating as your speakers. probably be able to pick a pretty good one up for dirt cheap there
remember, too weak of an amp and you risk burning the amp out, to strong and you risk blowing your speakers
edit* - something similar to this that matches your specs -

Ohh this kinda saves me from making a new thread...sorry to hijack this one...
I just got some B&W DM6's and was wondering if anyone could point me in the direction of the right kinda amp...
The manual I found just says "suitable for amplifiers between 25 and 350 watts r.m.s. under normal domestic conditions." ...they're 8 Ohms.
That's a wide range of amps to be looking at...suggestions please?

i'd go for something around the 300 watt range (8ohm of course)
after that, it's personal preference. A better quality amp will usually last longer and sound better. Put as much or as little money into it as you see fit tbh.
you'll probably get a lot out of info from googling "amp for B&W DM6"

It's already been mentioned, and I bet someone can explain it much better than me but, the most important part about matching speakers and amps are the watts and ohms.
Your amp should have an output of 150 watts on each side, with ohm's that match your speakers.
If your amp is too powerful OR too weak, you risk blow your s**t up. Without researching again exactly why this happens, I can't give you technical reason, all I know is that it can happen both ways, too powerfull or too weak...

Cheers for your help guys. Did a little research and asked around a few people and have been told I should be going for any decent amp which can supply 100wRMS into 8 Ohms (around 200wRMS@4 Ohms) and that should do the job.
As you've rightly said I don't wanna risk blowing em up...
I was recommended the older Studiomaster D or E series as they can be picked up quite cheaply by all accounts, so gonna do a bit of hunting around and see what I can find.
Cheers guys
