One of my favorite integrated amplifiers because the sound is detailed & crystal-clear. When used with various pairs of B&Ws and KEFs in our home, it makes me want to sell all the other more expensive amplifiers we own, none of which sound as satisfying. This is a keeper.

Decent amplifier. Neither overly detailed nor good at resolution. Soundstaging is weak to barely there. Speaker dependent of course. Average speakers sound good . Good speakers not so good as they reveal it's fairly significant flaws.
Fragile switches, overpriced as standard Arcam qualities.



re: Alpha 9

Can anbody suggest why there is no sound from the loudspeakers when the Headphones are still working? Ta!

re: Alpha 9

Glad to have found this site - I have one of these amplifiers (there seems to be lots of things go wrong). About this tie last year my arcam 9 stopped playing any sound from the loudspeakers. I'm not too technical and repairs are not cheap, plus nobody would help me with information unless I left it with them so I ended up putting it in the spare bedroom and bought myself a surround sound kit. As I say I'm not very technical, these days, but I should be interested to know if it is something serious or something simple and would be grateful if somebody could suggest what it might be. Perhaps I should mention that it still plays OK through the headphones. Thank You, Stuart

Hello, I just noticed the beginning of a issue with the selector switch (not know the actual name of the switch), when I change selection or put pressure on the switch I hear static coming from the speaker. Should I replace the switch or is there some other remedy?

Selector switch

According to forums on the net the problem is oxidation on the contact surface of the switches. (I have the same problem myself). The recommended solutions is a) deoxidation spray and b) replacing the switch. I you go for b) then the schematics should make it quite easy - if you ditch the motorization (and therebay lose the ability to control the input with the remote).
That is probably the path I'm going, altough I'll try the spray first. Regular 'cleaning spray' does not work.

component selector switch

I have the same problem. I tried spraying contact cleaner and then rotating the know a bunch of times. That works for a bit but then its back to music cutting in and out or nothing at all. I would love to hear how to solve this. I have never tried to fix any electronics so please make any suggestions dummy-proof as they say. thanks.

Great thanks

Just what I needed
Many thanks uploader

Brilliant, my alpha 9 doesn't power up and when replacing the fuse it blew again. Hopefully I can fix it with the schematics.


re: repair alpha 9 amp

I've just got my Alpha 9 back from the repair shop and when connecting the various components I managed to get an amber light and now it's completely dead! Anybody have any ideas?
