I'm unable to edit my previous post, so I'm adding this addendum...
NuForce owners always talk of value in respect to the high-performance/low-cost ratio of the Ref9.xx amps compared to the high-peformance/high-cost ratio of more expensive amps.
Id argue that there is intrinsic value in having an amp remain installed in ones system, and conversely there is value lost during the time a NuForce amp is spent out of the system being upgraded. If I calculate this correctly, had I purchased Ref9 monos a year ago, and if I had sent them back to the factory for the three (or is it four) ensuing upgrades, Id have experienced nine weeks of downtime once round trip shipping and actual time at the factory is calculated. Nine weeks of downtime is considerable value lost, IMO.
