I guess many of us are having to count the pennies at the moment, and PWB products slide down the priorities list, but I have found myself musing over a recent change in my PWB habits.
Even though I listen to music mainly through the Meridian Sooloos system, with occasional flurries of JRiver/JPLAY from a laptop (marvellous, but too buggy for everyday listening?),I still treat CDs. This is partly because they remain passive objects that influence overall sound, but a treated disc still produces a better rip - cannot escape that. But with all the message foils, treating a disc is not a rapid process. And the more foils, the more Leaf Green Cream needed to cover them etc.
I noticed recently though that my consumption of the Leaf Green Cream was slowing, quite remarkably. And then it clicked: whilst current discs (even live opera from the 1950s) sounds astonishing and better than any discs before, I am only using Rainbow Foil, and a few strips of X (barcode) and Inside Foil (either case or booklet)with Leaf Green Foil (LGF). Cream is used minimally, but the effect is better than ever.
So, although LGF is not cheap, it is almost all you need, and with less use of the cream, the result would even impress the Green Party!
