I ordered these two surge protectors...one for just the pre/pro and amp and one for the rest of my components: Tripp Lite HT706TSAT 7 Outlets 2100 Joules 6' Cord with Tel/DSL & Coax Home/Business Theater Surge Suppressor - Newegg.com TRIPP LITE TLP66NET Home Electronics Cables and Accessories - Newegg.com Hopefully they'll work on not degrade the quality or power.
