the problem with all that high end hi fi and with all that money involved it's easy to forget that what it really is all about is "listening" to the music and there comes a point where financially it is a waste of time upgrading....simply because as you grow older the hearing diminishes. Having said all that some years ago I had a demonstration at home of an LP 12 with an ekos arm and a troika cartridge....it took me to another level...
