First post, old guy, loves great music and sound. I have a barn with Crown DC300A Series II amp, Carver C-17 preamp, Nikko EQ 25 equalizer. 3 sets of speakers (using speaker switching box) Polk RTi 10, RTi8 and old Jensens in back. I have opportunity to buy SDA I and/or SDA 2. If I'm forced to choose without hearing them (don't like that) which pair does every one vote for and why. Barn is 30 X 80. Lots of area to fill up plus sound outside. I may also have to make my own cross over cables. I have a set of SDA 2A in house and love them - but wife doesn't like my volume levels.
