Actually, Trelja, your comment is so right on it is hard to believe anyone could seriously disagree with it. My SO's 17-year old daughter listened to my system (Hales Rev. Threes/McCormack DNA-1) for 10 minutes before proclaiming, "My friends' systems sound better. Your's doesn't have any bass. Even their car systems are better." She even had the audacity to smirk when she said it, too, the insolent little twerp! Just wait until I'm her Dad... Anyway, I would suggest that less sensitive speakers shouldn't be disregarded if they fit the budget and other parameters. All in all, very good advice.
Used speakers
I've recently upgraded and am giving my nephew my ancient Hafler 220A amp and Hafler pre-amp. The amp is rated at 120wpc. As befits a 16 year-old, he likes his music loud with lots of bass. I'd like to get him some used speakers in the $250 range. Any suggestions, biggest bang for the buck? Do I need to spend more?
