Steph, do you have links to Cambridge? It was all very hush hush.. They have had the CX and 851 series for a couple of years now and I think that's doing okay though far from budget.
Not directly no - I've helped out a couple of hi-fi companies over the years with odd manufacturing issues - typically because they want to manufacture odd things, use odd materials or improve reliability/manufacturability. I was contacted through one of them as a potential client/contractor.
Your (and maybe my) interpretations of 'far from budget' differ wildly from the expectations of the hi-fi business. I remember once reading about a $12k turntable being described as 'relatively affordable' and 'good value for money'. It's all very subjective: £3.5k/box for a system is relatively high up the tree, but there are systems easily running into £10k/box; cartridges and cables can easily get to mid-four figures and they're considered consumables...
My sister had (and maybe still has) Cambridge gear. We had a really fun afternoon at Richer Sounds twenty-ump years ago putting together her first system for her 18th. I've never owned any, although I rated their CD player very highly; I started, as many did, with a Creek 4040 which I rebuilt myself (it cost a tenner - I was a student), a set of home-brewed speakers and Thorens turntable. The amp eventually failed, the speakers are now with
@Yorkshire Dave and the turntable got bounced in a house move 15 years ago and is still awaiting time for its rebuild.
