@kirkwallace I don’t know how you validate their claim except to research reviews to see if anyone has had problems. If you don’t trust that claim in the product specifications how do you trust any claims.
Basic surge protection with some noise filtering without strangling the amplifier?
I’m looking to get a basic multi-outlet surge protector that has some basic noise filtering and that has at least a few outlets for high-voltage equipment (amp in my case) that will not kill the sound of the amp.
Do those of you with practical experience and/or technical know-how think that that the Furman Elite -15 PF i fits this description? (From its own write-up, it does.) Are there other devices in roughly the same price range (<$1k), that I should consider?
The amps in question are a JRDG 625 V2 and a CODA CSib.
For one data point of comparison, I tried plugging the 625 V2 into a Torus RM-20 and while the sound floor did seem improved (from already very quiet to even blacker), the sound quality immediately suffered a lack of vitality and dynamism. So, the amp is not connected that way any more. The other upstream components (pre-amp, Roon Nucleus One, streamer & DAC) do seem to like the Torus though.

Exactly, in part, why i started this thread. Short of finding independent lab test reporting that is peer reviewed and validated, I am interested to hear what others have experienced. @ghdprentice , for example, reported that he has had bad experiences with these sorts of devices, although maybe not specifically with one as basic as the Furman PFi.

If it’s within spec then yes, a Furman with AR is a fabulous device which keeps your gear behaving optimally.

Yes, thanks, as always, @erik_squires . This conversation about voltage fluctuations so piqued my curiosity that I went ahead and ordered one of those AC plug in volt meters that you linked. (Feeling very “I gots to know.”*) Obviously it does not provide any voltage regulation, but, Erik, do you by chance have a view on the Furman Elite PF-15 (or -20) PF i unit?

@kirkwallace - I own the Elite PF-15i and I've several times noticed it when it was absent that my stereo did not sound as transparent or clean. When I was in San Francisco I enhanced it by adding an AR unit after I measured 130V at the wall. The power factor correction and trigger outlets were really useful for me at the time. Also, one extremely useful feature shared among the series mode protection units like ZeroSurge and Furman with SMP, is the undervoltage/moderate over voltage shut off. I've been sitting in the living room minding my own business when the lights start to flicker, and my Furmans immediately shut completely off. Turns out a vehicle had been too friendly with a power pole. Sometimes I've come home to find the EVS alert on another unit telling me the power was cut off for safety. Between that and the times my UPS start chirping I know for a fact I get more power issues here than just predictable weather. |
