Re the split between Linn and Naim audiophiles, I think that may have it's origins in the launch of Linn's own amps. Until that point the two brands had been seen as synergistic, with each company recommending the other's products as being the best match for audio nirvana. If I remember correctly though, at the launch of his new amps, Ivor was highly critical of the Naim designs, and the great divide began...
