Over the years I have enjoyed my Ref 9 amps, upgrading from Ref 9 to 9.02, V2, V2 SE, and V3 SE. I am ready for further upgrades, especially now that even better sounding amps are on the market: NuPrime's own Ref20, but also Hypex nCore, Auralic Merak and some others. There was always the promise of further upgrades to Ref 9, either with CMA like Ref 18, better power supply, Ref 10 or even V4 iteration. Most of my questions about this have gone unanswered by NuForce, and the answers that were given have come out false ("Ref10 will be here soon" etc).
My question: will there be a serious upgrade path, either through technical upgrades or trade in, for Ref9 owners? Or should I forget about NuForce/NuPrime?
