Consider small stand monitors of high quality with powered stereo subs. You get great soundstaging, clarity, pinpoint imaging and deep powerful bass. I have full range speakers with subs. It is amazing how much better the full range speakers sound, freed from the reproduction of bass. Were I to start from scratch, I would go with stand-mounted monitors with subs driven by a less powerful, class A amp.
Merlin VSM
I moved my system from a small room to a larger one 20 x 13. There is simply not enough bass from my KEF Reference 201/2 (associated eqip. is Aesthetix calypso, Primare A32 amp, Marantz SA1060 CD, Supra cabling). Would the Merlin VSM (MX or MXE)provide enough bass in my room? I am looking for a floorstander with a superb tweeter that is available used for $4000 or less. Music choice is primarily acoustic folk, rock and blugrass with symphonic music also (I know, weird combo). Thanks for your insight.
