I started looking at the Furman AR-1251 15amp unit @$450 recommended by an enthusiast on another forum and it looks pretty well-rounded as a voltage regulator AND a surge protector. Furman is a pro-audio manufacturer. Here's web specs This is quite compact at 12lbs alongside the MonsterAVS2000 voltage stabilizer at 38lbs and $1150-$1500. Not saying they are comparable. I previously believed power voltage delivery does not fluctuate enough to exceed the equipment power supply specifications; but I do not know and have not metered my own circuit. I am sure there's a lot to be said for the certainly of steady, constant power supply to HT audio-video equipment from such devices. At the least, constant power supply is said to least degrade electrical equipment over time that is subject to voltage fluctuations. The Furman appears to cover surge suppression according to UL 1449 standards: *The highest spike protection mode (line to neutral, neutral to ground,line to ground) *Let-thru voltage of 400V, which is inside UL's 450V limit but above "best" of 330V *Maximum surge current to 6500 amps where 6000 amps is UL's new high-standard rating. Furman does incorporate MOVs. No Series Mode "brickwall." Am I missing anything? No coax or tel line terminals or convenience features. But neither does the Monster unit. This unit looks pretty good in our quest to find one-size-fits-all for mid-fi AV systems. I do not know "pro audio" like Vince Maskeeper. I found this caveat at AudioAsylum: The Furman products are geared towards the pro side of things and the Cinepro is geared towards the consumer Hi-Fi side. The Cinepro power line conditioner units use larger power transformers, upgraded A/C outlets and more A/C filtration. The CinePro Power Supply II (15amp) lists at $799 and streets at $699. Ouch. Any takers?
