Thank you Larkrise.
Yes they are very good and If I sell them they shall be missed but I need cash for a very different project and this is the only element of my hifi that I can sell without rendering the whole setup useless!
I believe Audiosmile can change the filter to suit the users own loudspeakers and I am waiting to find out what the cost of this is.
Again, please pm me if at all interested.
Many thanks.
