Thinking about going to Mac gear. Right now I'm using a Pioneer SA-9500ii or a Lafayette LR-9090 receiver with Celestial-Ditton 442 or JBL L100's. I switch back and forth between all the components. Right now in my area there is a MAC 2205 amp with a C 28 pre-amp for sale at what seems to be a reasonable price. Also at a lower end is a MAC 1700 receiver at a fair price. I know there is quite a difference in power between the two but also a big difference in price. Ive also read if i want a receiver the 4100 is the one to get. Any thoughts or opinions?
