I am looking into purchasing either a VP100 or VP150 along with M3Tis. I am using a H/K AVR 320 (http://www0.shopping.com/xPR-Harman_Kardon_AVR_320). The room size I will be using is 12' x 20' with 8' ceilings. If I get the VP150 I will be really stretching my budget. I am considering getting the VP100 but am concerned I may be disapointed. I guess if I am I can always go for the VP150. Any input on this decision.
