Mike60, yes it is me, but than I talked to some technical people and was told, that noise issue may be related to brake in period and I need to spin it off at least 500 hours, bottom line I bought esoteric (this time again k-01). When I opened this thread, I new how k-03 sound, but needed know much better K-01 is. Well, after having K-01 in my system for about 300 hours I would say it is around 10% better in my system, may be some more (depends on the cd quality) and if one have highly resolving system it makes sense to go with K-01, but for medium level system the K-03 is awesome and even if it makes noise in the beginning it may go away after some hours, if not one should contact esoteric, their shave a different management team know and they provide great service and really take of the customers.
