Hi, I'm D.

I bought this amp to set up a decent home studio (almost 6 months ago). I invested on the RA150 and the Alesis monitor one mk2 after the guys at my local shop recommended it to me.
The result is really good!!!

Nothing to say about the brasses (jazz), classical music violins and layers, the kick and snare drums (hiphop) come through very nice, and don't even get me started with the basses!
They are almost noiseless and even if you ever hear some noise it's probably due do how that particular sound was recorded.

To be honest, this gear has really made me develop my chops, both in terms of songwriting and mixing.
So I really recommend this amp with the Alesis mk2!!!

EXCELLENT value for money!!!
Would I buy it again? Yes, yes, yes!!!! (however, if I had more money I would look at more pricey options).

To conclude, they are awesome for computer music, songwriting, mixing, hip-hop and r&b recordings...and they allow you to get a good home-studio quality.

Edit from June 2010
After moving it with this heat, it won't power up.
Then, once I got it sounding again, sound was intermittent.
Sound just came on and off, in other words, impossible to use to make any music.
I hope it's only a false contact or the tube that needs to be replaced. I'll go tomorrow to the shop to see what's wrong.
It's a real pity because I was very satisfied with it.
It seems I'm not the only one with this issue, so its quality certainly leaves a lot to be desired.

I'll tell you more in a couple of days and revise my review, if necessary.
