i have the nsp1 one right now, and wanted to upgrade the mains to either the n26 or n28. i plan on using the old n24s as the "b" speakers around my computer (as right now the setup is a bit funny and i have to move speakers all the time). now, i unfortunately missed out on jandr's good deal on the old style (non-markII) n26 speakers, so here are my options: n26II from jandr: ~$160 shipped. n28 from half.com: ~ $166 shipped. here are my questions: is half.com a reputable place to buy stuff if the person has a good seller rating? also, is my warranty going to be voided by not buying from a place like J&R's? is the extra two decibels of sensativity and slight frequency response edge on the n28s worth it? what stands are recommended for the n28s? i am assuming since it is a more normal design, unlike the n24s or old n26s that any standard stand will do?
