I have always been wanted to build a nice system. Finally, last month I bit the bullet and I bought the Sony S9000es, B&W N805, and Mcintosh MC2155 in one shot. The Parasound Preamp was something I bought on Ebay as a starting point. I read a few reviews and thought it was great value. My system sounds awesome. I haven't had much time to do any tweaking because of business. To compliment my system I have a Lovan Rack, Cardas Cuboids, and various isolation cones. My first upgrades will be in the area of Power Cords. I hope that you guys can give me some insight into this realm of Hifi audio. I don't really wanna spend a small fortune on PC's. I have looked at a couple of DIY designs like VHaudio. I have also looked at the entry level Nordost offerings. My budget is around $150-$200usd. Also if any of you have any opinions on my overall system please feel free. After the PC's I would like to upgrade my Preamp. I have two in mind: The Rogue Audio Metis Tube Preamp ($995 Retail) and the Prima Luna Prologue Three Tube Preamp ($1395 Retail). The reason I want to try a tube Preamp is to improve the highs. Is this the right idea? I have to base my decision on your help as no local dealers carry either. The most amazing this I have realized since my big upgrades is, redbooks cds I originally thought were great recordings really suck. =) I guess this is what audiophiles mean by "more revealing". Better systems do reveal bad recordings.
