Questionable Tweak


Someone on Audiogon mentioned using an air purifier to improve the sound of their system. I dragged my wife's purifier into my listening area, cranked it up, and.......,no change at all. They said it removes dust particles,to improve the sound. Has anyone ever heard of this?Is there any science to back this up?

I've found the opposite to be true.

The more cat fur/dander floating around here - the better the system sounds.

When I vacuum with our Purple Dyson (designed for furry pet households) the SQ drops for a day or two.

Don't believe everything you read.

I tried an ionization based portable air filter in the 80's and found that it quickly caused a thin buildup of difficult to remove residue on everything in the room (including the walls/ceiling/windows). 

After going through a few gallons of TSP I gave it away.

We have open windows whenever the temp's drop to 70, or below.

Being located 11 miles from the ocean (West Hollywood) there is also a nice subdued marine layer most evenings.

This said, what's emptied out of the vacuum canister is a bit frightening.

Rodney Bingenheimer turned me onto the cat fur/dander tweak in the late 70’s, while we were dining at Danny’s Oki Dog (no public Internet then).

He said it made his Rogers Sound Lab 3600’s sound like Tympani 1B’s.

Yes, and I saw 2 pairs of them (different occasions) @ the Goodwill across from Live Cheetah's in East Hollywood (pre-Covid, so maybe in 2018/2019).

I would have picked up a pair (think they were around $60) but knew that our cats would kill them as soon as I fell asleep.

My favorite part of Rodney's show was him trying to remember the songs that he had just played (we would applaud if he got them all).
