fresh powder snow in the countryside? The zillions of crystals of water are doing a perfect job of damping noise - at least in the audible spectrum.

I used to ski a lot in a place called "Valle Nevado" , it was only 45 minutes away from where I lived . One thing I clearly remember is that when all was calm , the silence was totally different compared to the silence you can hear being very far away on a highway or similar . Yes I totally agree with your observation .
And for Romy , heres a little story I haven´t tell ; About 2 years ago I bought one cd player from a very fine store (USA) and bring it to Chile , as for that time was my favorite CD player I decided to buy a second unit but this time only the DAC . For that time I was experimenting with a lot of cpacitators so I opened both equipment and look into the DAC boards , they were exactly the same , every single chip , everything was identical . The only diferent thing was that in one board , either one , you could connect the transport . Ive changed 2 capacitators on each board , the same values , same brand , they where all new and very good quality . For my surprise when I connected everything back ; one of the boards sounded very different (there was a hf noise that make my ears bleed) , so I decided to change everything back . With the old caps both boards where the same , with the new ones (better ones) one board sounded very bad . I did try like 10 different caps on both and there was almost always some kind of different , being extremely big with some caps . I never took it at the level that Romy took pp2000 , but the point is that there are so many variables out there that can make 2 equal equipment sound different and that those variables im afraid we cannot measure .
