Hey Chris,
I have bought quite alot of CA kit over the last 5 years or so, and I agree about reliability problems.
I've had:
2 540D dvd players:
first was DOA, the second had BAD colour problems and really gritty picture quality.
Got a refund, bought a Sony upscaling player instead - quality.
2 640C CD players (V1's)
first blew a channel after 8 weeks, the second dead on both chanels after 8 months.
Got a V2 for my troubles (thanks Richers) and it worked fine.
Until I sold it when I got into Music server/Dac replay.
I'm still running a CA 640a amplifier but its now developed an intermitant "dry joint" problem on one channel.
Makes you wonder.....huh?
No more CA kit for me (well, maybe an 840a if it trumps a Nait 5i that is)
Ok with not having it on Betamax nowadays
