I have the Furman P-2400. It has saved my gear from a few power surges. For example, recently a construction worker cut power to my house. When he turned the power back on, all the gear that was plugged into the Furman survived unscathed, but my dac which was plugged into another power conditioner would no longer power up.
The P-2400 is very heavy and well built. I like that it has 14 outlets. It can draw 20 amps. The Furman can handle almost any home audio system, with current to spare. My current system only draws 3.5 amps, so there's a lot of headroom. I had an OTL amp which created a current draw of 8.5 amps for the whole system, so the Furman worked well even with my power hogging OTL amp. The only drawback is that it has a captive power cord, and the front display cannot be turned off, but it can be dimmed. I bought mine at Amazon Warehouse for a great price, more than 50% off retail. I have only compared it to a low end PS Audio conditioner, so can't comment on how it would compare to the other brands you are considering.
