I am not familiar with every model and feature, but I have the 800 and the HTS-3500. The 800 was an improvement over nothing and did have a rating or 1350 joules if I recall correctly. It did lower noise floor a bit. I once lost $5000 worth of gear to a lightning bolt in my NYC apt. (And I certainly never thought it could happen here, or to me!) Megasam is probably right about the HTS 2000 being a good deal but, I really like having a "component" in my rack for power conditioning and cable management. I haven't compared the 2000 to the 3500, but the 3500 is an excellent product in its price range. Maybe you can find a deal on one. At least you can count on good protection from the elements while you think and shop around. Good luck.
Monster Power AV-800 any good?
I have my Rogue 99, Rega table and C.E.C. player plugged into this fat,purple power strip.My Dynaco is plugged into my other outlet alone.I bought the Monster($50.00) for the surge protection alone in hopes it would also improve the sound but at the very least do nothing but protect from lightening.Is this thing any good.My dealer freaked when I told him I have one.
