The Anthem receiver really impressed, it was detailed, bold and dynamic. At first, it was hard to tell any difference between the Anthem and the Arcam. Further listening with a range of material revealed that the Arcam was slightly warmer and subtly separated instruments. The Arcam had slightly more base whilst the Anthem delivered voices with additional gusto because it is slightly decreased in the bottom range. These differences were subtle and both are excellent receivers and well worth an audition. They were hard to separate with the material or the speakers. However on a second audition and given the slight differences the Anthem wins in both price, technology and reliability. The room correction is amazing and unfortunately the Arcam has reported reliability issues in the forums. The cost difference in Australia is over a thousand dollars extra for the Arcam. With the all round package of great sound, room correction, video processing and cost I think the Anthem is a no brainer. Well done Anthem.
I also have heard both these receivers with a 5.1 set up previously. They were outstanding in producing detailed Blue Ray effects, voices and music. The ARCAM was set up with a M&K 150 system that really performed well with all materials. I was pleasantly surprised. The Anthem performed with equal muscle while driving some VAF speakers in a 5.1 set up. I can’t really comment on a comparison as they were both auditioned with different speakers and subs several weeks apart.
