... the 2405s really don't need much power at all!
How about using one of those T-amps -
they are mighty cheap and pretty clean.
I'm not triamping my L200 3ways, but its certainly worth a try ...
Seems like $25 is a worthwhile price to try one, doncha think?

I got one of these around Christmas and have been playing with it -
my original plan was to amp an iPod with a pair of walnut Minimus 7 speakers,
but I tried and was amazed what I did with a pair of Ruark Talisman II speakers.
It WILL get noisy if you push too far, but below that point its very impressive!
