In Tennis vernacular, "Point, Set and Match" awarded to Mcintech for his post.
W/o prejudice to the build quality gremlins discussed, sonically the ARCAMs, have been and continue to be, among the very best of all the AVR alternatives.
FWIW, I had the very top CAMBRIDGE AVR which rivalled all but the very top unit of the ARCAM line. Like the ARCAM it is also fine, fine kit that also beats 99% of all comers; but it also had a similar MB solder problem that was fixed under warranty.
That is why the 3 years warranty for CAMBRIDGE and -- even better yet -- the 5 years warranty for ARCAM are so valuable and desirable.
Contrast these with the limited warranties available on most of the Asian products.
PS: the ARCAM Blu-Ray is robust and beats everything else out there for HT including the high quality kit offerings from OPPO and my old CAMBRIDGE (latter two clones of each other). ARCAM can and does make good products.
