May be KM or HR or JA could keep this Cambridge Edge A around for a while and review some of the 'affordable' loudspeakers under $5,000 or even under $10,000 :-) ............

Welcome to 21st century :-) ...........

This will be the amp that will replace my good old and oversize fpb 300 heater.

The headphone output impedance of 10 ohms is not low. It's high enough to interfere with the sound quality of efficient headphones. By way of example, the Schiit Magni 3 headphone amp has an output impedance of 0.6 ohms.

Agreed ........ All the portable Chord self-powered head-amp/DACs like Mojo, Hugo2 and Hugo TT2 have headphone output impedance less than 1 Ohm .......... Rogue RH-5 (Stereophile Class-A) has head-amp output impedance between 1-3 Ohms .......... 10 Ohm output impedance can drive top of the line Sennheiser and Focal headphones and some others with high impedance :-) ............

"The CD1 two-box CD player ... was the most expensive CD player in the world at the time." - sounds like misinformation, to say the least.

"[In 1986] Cambridge Audio's CD1 cost a fortune at £1500. Double, if not triple, most other players."

Technics SL-P50P - 1984 - $4000. I'm pretty sure there's more examples.

An amp that turns itself off after a few seconds with a fault doesn't sound like fun to me. Especially not at this price point.

Last time Stereophile tested a flagship CA integrated (the 851), the first sample broke and the second was faulty. This time the first one broke.
On this evidence, isn't JA being generous with his assumption that the shipper was at fault? Seems like a bit of a trend is developing, slightly worrying on what are not cheap items.

Personally, at this price I'd be looking at items manufactured in-house, not outsourced to China.

Thanks for a great magazine, by the way.

What did you expect? It's MADE IN CHINA.

....demand that any hi-fi (possibly any electronic device) unit running a negligible signal for more than 20 minutes must power down. And it's easily defeat-able; I was only making note that it's bothersome.
Beyond the issues that greeted JA after I had the CA in house, build quality was excellent, the unit worked perfectly, and sounded fantastic, never mind where it was manufactured.

"A few seconds after I first powered up Ken Micallef's review sample of the Edge A..... it turned itself off, its front-panel light glowing red to indicate a fault" says JA.

What's that got to do with "Brit" regulations, and how is it defeatable?

And build quality was excellent, the unit worked perfectly, and it broke and had to be replaced.

May be you (KM) could review one of the ATC self-powered active loudspeakers, preferably with the ATC CD player/pre-amp, you recently reviewed? :-) ..........

Ken mentioned this is the best integrated that he's auditioned. And I see that is not a small number in the past few years. Is this piece really more impressive than the Luxman? I ask because I'm demoing it right now. My old Krell KAV300i is getting long in the tooth and I was looking for something a bit more refined. IMO, this is a really nice piece; well defined sound and easy to listen to for long periods.
