Hey Larry, just to inspire you some more. I had picked up two X-LS kits in the Memorial Day sale that Danny ran to make for high school graduation gifts. We finished up the first set yesterday and listened to them for a few hours right next to my N3-TLs and I was really, really impressed.
Mids and highs were crisp but natural. The bass was absolutely amazing and tight. The 18-yr old kid that they are for wanted to help build them and he worked hard on them, so I reluctantly gave him the prime listening seat

. The soundstage was big. They imaged well and I had a total blast introducing the next generation to good music (early U2, Cure, Smiths, Cult, Pat Metheny, Roxy Music, Tracy Chapman, Steely Dan) from my teens on some quality equipment. The X-LS played them all well, all while filling a really big room. Lot of fun.
BTW, He's hooked...so pass it on guys.
