I've been thinking hard about my best upgrade strategy and I reckon I'd be better waiting until my new room (12 Months or more away) to spend some major money. However, there seem to be some interesting classifieds that could improve my system for very little outlay. I've agreed to buy a Kef Model 100 Center (collecting Friday) at £50 more than I've already sold my Q95C.1 for. This will go with my Kef TDM34DS surrounds. I've seen some Mission 753's (Not Freedoms ) that I could buy for the same price (or less) than I could sell my Kef Q55.1s for (I have a buyer for the Kefs). Would this be an upgrade? Would the Missions be tonally compatible (They have previously been used with the Kef Model 100) Also, I've seen a M&K V-75 Sub for £275 is this a good sub/deal? It's to replace my Yamaha YST-SW120 until I can get a Servo 15 in my new room. The way I see it there would be a second hand market for all these bits in a year or so's time, but I don't want to find myself taking a step backwards. Cheers, Mark.
