I've had some Cambridge Audio equipment mainly a preamp and a cd player. Very nice performing and well built. However on this amp 1)it seems to be for 220-230v only, 2)it runs too hot to touch due to its class A (or in thes case they call it XD, which is not class D but some sort of automatic adjusting Class A circuit), 3)if you run them bridged, be careful of your connections and your grounding (don't run a powered sub off of the speaker terminals), and 4)you can find them new and lowered priced on several direct internet selling companies.
The Azure 851 is a great amp. Very mellow sound, plenty of power, stable into 2-ohms stereo.
The only problem is you have to deal with Cambridge. After purchase support for the 2 items I own or owned was Mediocre at best. Imaging CHARGING for a FW update? And this was with a top-line (over 1000$ cd player......They sent me the update. But I needed a Null-Modem cable and I think it only worked with Windows XP at that time. If YOU try this at home and brick it? They'll smile (since you can't see 'em online) and tell you it'll be some huge sum to set right...... Than? Just TRY to get some help without being told to send it in for the famous 'flat rate fix'.......And that NO, we do NOT give out schematics.....How stupid do you think we are?
Sorry. Anything I buy new will COME WITH a schematic or forget it. And it Will Not be from Cambridge Audio......
