Going w/tubes does not necessarry mean you're going to get the sound you want. Some inexpensive 70-80's Solid state equipment (Rec./Int. Amps) sound great and has pretty decent phone stages as well. The finest inexpensive spk. that I've ever heard in my system is the small Tannoy Mercury MX-1M Monitor. The newer Fusion 1 is good as well but not as nearly as good the MX-1M. (I've listened the the "Mites" and was not impressed w/their sound. But, the whole name of the game is matching components which work well w/each other and the room!) A good sounding amp and source equipment will make any spk. sound better. As far as spks. go, generally a soft dome tweeter will provide a warmer sound. If you go w/a small bookshelf spk., good stands will be needed and they will be needed to be filled to make them more stable. Considering the size of your room, 5 to 6 1/2 woofer should be the enough for good bass. Good Luck!
