Nice speakers you have, no need to change those.. my 2 cents is IF you like the quickie then go with the big kahuna... the beepre has to be one of the finest preamps on the market.. Then with THAT in the chain as a "constant" reference, then you can evaluate and play around with amplification later.. You need some constants to build a system around. So, IF you love your speakers and they arent going anywhere, and you have a reference class preamp like the BeePre.. You can build from there...
