There are some inexpensive devices on the market that can solve the problem for low current devices but they also dramatically hurt audio performance. The Isotek is the only hi-end solution that I am aware of. We have developed prototypes that solve the problem and can handle over 30 A of current and sound quite good even when used with mega dollar amplifiers.
We just haven't decided if it is a problem that would provide a return on investment. The circuit could be added to an existing or up coming power conditioner but in our opinion it would need to be defeatable because 90% of the people would not need it. And then it adds to the cost of the product unnecessarily.
If we created a stand-alone DC blocker product, it would probably be the most expensive product of its type on the market. Necessarily so to perform at a level we feel is adequate to be used with +50K amplifiers without degrading their sonic capabilities.

Caelin....You can add South Africa to the list and Burmester's conditioners also have DC blockers.
I would be very interested in a stand-alone DC blocker product.
