Not surprised the 3510 gets such a good review. Exposure have been quietly about their business making excellent HiFi for years and years. Perhaps they undeservedly get overlooked in favour of more shouty competitors.
The 3510 is a purposeful choice to make this the hub of your source options. A nice antithesis of the now common all in one box. That’s what I did when buying the 3010 pre and monoblocks. I get what you say about the 3510 being a Supernait 3 contender. SN3 was on my home demonstration list but I went for the Exposures. My stuff uses a Qutest with Node 2i and through Neat Orkestras, it’s wonderful.
Good to read this review. The 3510 is on my shortlist to partner with my Roksan Caspian M2 cd player and a pair (for now) of vintage Mission 752 speakers. It would be replacing a long in the tooth Quad 33/303 - which I may yet choose to refurbish. As I have yet to audition the Exposure I'd be interested in views on how the sound will differ from the Quad combo.
I have had my eye on this amp since it's launch, but the problem is availability, it seems not many dealers were stocking it when I was looking to upgrade. I actually love that it has more analog inputs than most these days, 2 lots of pre-outs plus a record out, and one can choose Phono pre amp or DAC., I also love the look of it. The phono earth pin position is a bit odd though.
