New owner here, just purchased in the past month a Marantz 5200 (no problems so far, just great sound), paradigm Atoms as mains, Micros as surrounds and PDR 10 Sub, with Toshiba 2710 DVD and the same old Sony 5 disc CD player. All told sounds real good (Previous system consisted of Dynaco A25 speakers and a Sansui integrated amp bought during first year university in '74). Still learning to walk with this HT stuff though. One question...the speaker stands come with optional spikes, and I don't know if I should use them or not. They are the Premier stands that Paradigm recommends. (LS -40). The stands are on hardwood floors and I don't know the plus and minuses of the spikes. What purpose do they serve? Any help would be greatly appreciated.
