TVSS (transient voltage surge suppressor) or similar whole-house surge protection mounted at the main panel has become fairly inexpensive and offers some good protection for all of your house electronics. In looking at the Sola link, I think soundhound raises an excellent point: that appears to be an industrial product, not a residential product, and industrial power concerns are very different. They are looking at reducing failure rate on large horsepower AC motors and other gear, and the methods used to accomplish that may not be well suited to a residential application.

I also skimmed over Naim's power page, and I do seriously question their recommendations. First, surge protection is valuable, and not just to deal with lightning strikes. Tomorrow is the one-year anniversary of what the local news channels have named "Hurricane Elvis," a straightline wind storm that took out power in 3/4 of the Memphis area for several weeks and damaged or destroyed about 1000 power poles. The power surges and sags experienced as the power began to fail in different areas was sufficient to damage unprotected equipment (one of my co-workers lost a VCR, suffered some damage to a TV, and blew a fuse in a $3000 preamp). I had my system on a Panamax MAX5100 and experienced no problems, although my microwave's display did take a hit and has never entirely recovered.
