Coldfusion:Tarquinh, I totally agree. I have read quite a few reviews from French to English on these and I bit the bullet and bought the A57, C57 and T57. With my setup they work really well and I am shocked that they were rated so badly. I have been reading What HiFi reviews for years and have always been normally impressed by reviews in the past and how true they were to the products when listening to them in a demo room or home. The Carats, However. I do disagree with as they are way better than 2 Stars for the amp and 3 stars for the CD Player. To my ears they sound better than my old Technics SU-600 and Nad C515BEE combo and also Sony STRDG820 and Nad C515BEE combo afterwards which also sounded quite good to my ears. Of course this is just my opinion and may sound different to others and I am sure different leads and speakers also come into play.
WHFI always base their findings and grade it on pound-per-sound. Correct me if I'm wrong but the Nads were the budget models and Technics is pretty old now, so comparing it to a £1,000 amp/cdp one would expect the 1,000 pounder to show significant gains over a budget set-up. I've personally not heard the Carat, so can't comment on the sound, just the review findings.
