This is really interesting. I have a Quad Artera Pre and I am currently using an Anaview AMS1000 module in a s/h Cambridge Audio case. The Anaview was only ever intended as a stopgap, but it sounds so amazing I held on to it longer. I originally intended to buy the Artera Stereo to go with it as the obvious match, but my experience with the Anaview has given me massive second thoughts - that maybe a NAD C298 would be the way to go. I brought along the Anaview to Doug Brady's and listened to Kef R5s, Spendor A7s and Proac DT8s through both it and a Quad Stereo (I was ostensibly auditioning speakers). In each case it was clear the Quad had more 'weight', e.g. Volodos playing Schubert had more heft to the piano, but there was a nagging sense throughout that the weight was accompanied by a bloom that wasn't neutral. It wasn't an obvious thing, just a sense and I would have to audition at home to be sure. I think the Quad would be a safer buy, but I also think a NAD C298 would supply the heft that is missing in the Anaview without adding the bloom. I saw that you were using an Artera Play, so your experience with the Purifi is fascinating to me, though unfortunately it's only complicating matters!
