My understanding is that the 1704 dac ceased production a good few years back so where does ‘new’ stock come from. There was a new player recently announced (cannot recall the manaufacturer as i write this) that uses the dac as well. Odd.
Its fantastic when a company expects expectations! When I put a leica in for service I was amazed when they popped in a new shutter in free on the grounds that it was all apart anyway- something I’ve never forgotten-decades later.
Likely they found some NOS chipsets, or maybe bought up the ones that didn’t measure to Naim’s requirements . If it’s a low volume player (let’s face it any hi -end player these days is going to be built in very small numbers) then using NOS parts is quite possible.
At £2500 I would have thought that the Exposure CD is unlikely to find that many homes, it is going to be a very niche product, so maybe there are enough chips for a small scale build of new players plus there are a few chips floating around for spares/servicing.
