if it ain't Baroque ...
Ever heard of Shungite? According to Wiki, 'The term "shungite" was originally used in 1879 to describe a mineraloid with more than 98 per cent carbon...' I came across it the other day, and ordered a small quantity for curiosities sake. However, I placed the two small samples on a TiVo box, and low and behold, better sound from the Dacmagic it feeds. So I ordered some Shungite 'tiles', and placed them under and above said Dac. Again, same result! Now I'm not suggesting this Shungite works, but I am hearing a difference for the better. One 'tile' measures just 1 Ohm for nearly 150mm length! About this time, I bought a very cheap phono amplifier, with SMD transistors and class A working. On start up it didn't sound all that great (not surprising for under £30), but after a week away with the thing switched on all the time, I placed another Shungite tile underneath it, and a bag of Shungite powder on top. The little cheap phono amplifier has now replaced my MF phono. Sound is a little sharp, but wearing in nicely. I don't know why the sound has become more coherent, but in addition, it may have affected my amplifiers as well. I run two Cambridge Audio 640Av2 integrated amplifiers, one per side. The left hand amplifier has a habit of distorting due to a poor relay contact, on switch-on. Several input changes usually clears the problem. But since using Shungite, there have been no problems. And the volume imbalance (from the two amplifiers) has gone away, as well. I'm not saying Shungite is responsible for any or all the improvements, I really can't see why it should. All boxes of electronics are well shielded (except the TiVo box). ???
