I recently bought an ex-dem Arcam AVR-500 with 5 yr warranty for 999 after demoing it against a SC-LX73 and a Yamaha 3067. TBH I wanted the 3067 or the 73 to sound best as I'd heard on forums of some issues with the 500.
but within a 2 channel demo the 500 sounded leagues better than the 73 and much better than the 3067 as well which I placed in my mind in 2nd place
took the AVR500 home on approval as was concerned about (1) lack of power - the 7x85W seemed way down on my current pioneer AX10Ai which manages 7x130W and (2) bugs
but once home - WOW - the sheer clout the 500 has blew me away - this is for movies- my speakers sounded more dynamic than ever and went very loud without breaking into a sweat - by far the best I've heard my system. Music in PLIIx mode (expanded out across my speakers) sounded sublime and Dolby Volume was quite a revelation for late night movie playback (something the Yamaha and Pioneer don't have). The build quality of the Arcam is excellent- its a very heavy receiver and is dominated by a huge heatsink front left and a suprisingly large Torrodial transformer - it looked about same size as the one in the Arcam AVR350 I owned a few years back in the pics - but in person I could see it was far deeper/taller - so overall looked almost twice the size of the one in my previous Arcam
BUT it shut down due to heat (with a pop through all 7 speakers!!) - phoned Arcam and had to be sent back for mods - this leftme a bit of a sour taste so in meantime I borrowed the Yamaha 3067 (2nd place in my demo) for a night -incase the sound quality was nearly as good - but with less bugs - more functionality etc. Also the Arcam does make some annoying pop noises through random speakers as it negotiates the HD codecs
For my 7.1 system (YMMV) though - there was no contest - the Yamaha wasn't in same league as the Arcam - gone was the open/dynamic/ movie playback and within scores in movies seperated instruments sound of the Arcam, and gone was the power and dynamics at volume. Sort of to be expected as at different price points, but the Yamahas are very good for movies, and 90% of my viewing is movies/TV - so I wasn't quite sure what to expect
to be fair to the Yamaha though it did sound amazingly good for the £750 or so you can pick them up for now - but I far far preferred the Arcam
Am I concerned I may need a spare cheap receiver if the Arcam has to go back for repair (my TV is a panel with no speakers) ? yes ... Do I think I can get similar SQ sub £3k - no - hence why its a no brainer really when you get a 5 yr warranty. It genuinely sounds so good that you can live with some of the drawbacks
oh btw - for movies (even HD codec Blurays) I still preferred the sound and power of my Pioneer AX10Ai over the Yamaha - even though I'm limited to legacy codecs to the Pioneer vs I was using bitstream HDMI lossless into the Yamaha
