"Aimed at anyone who loves music and wants more sound for their money, the last release of the 606, 607 and 603 speakers all received five-star What Hi-Fi? reviews. We look forward to listening to the Anniversary Editions in the coming weeks"
According to the article, "these new models...replace the current versions of the 600 Series speakers," if that's the case, that seems to be a rather quick refurb on the existing line which came out in 2018. I feel kinda lucky now, saved €250 buying a set of 606, 607, and HTM6 back in March when they were discounted. Incredible sounding speakers, at least to my ears, a vast improvement in detail and transparency compared to my old Wharfedale Diamonds.
