When you say stereo you really mean 2 channel don't you. Todays "stereos" really have 6 speakers called 5.1.The 1 is a separate subwoofer. ... Playing my 2channel Music , AuralMoon, or my 1000 recordings. Dolby Pro-logic2 is a must. the Imaging increases, The centered singer/solo is stronger, and the natural aireness is enhanced, flipping back to "stereo" calapses the field and most tunes fall flat in comparison. Also very few speakers even towers are fullrange reaching to true lows. A sub-woofer adds a great deal to ''just music". Your amp. probably can't tool out because power drain for Bass and Mid-range is 10 times more than acoustical Highs. Your probably unpowered and under bassed. Adcom does indeed make nice pre-amps,Almost all are 5.1 models, it's the power amps times 5 that cost. Your towers are just fine, You would like to get a center speaker in the same brand but you can cheet with some of your old ones for the 2 surrounds. Finally DVD-AUDIO and SACD discs are the finest sounding material available. Most mixed just for the 5.1 set- ups .Porcupine Tree'sIN ABSENSIA in DVD-A is incredible....I'm mostly concerned with your room acoustics so let me do a primer in your next answer.
