Indeed. Wish they'd introduce their next upgrade to the Ref 9's. That would liven things up. Some time ago Jason mentioned plans for a Ref 9 CMA board upgrade.
There is an upgrade available by the "Upgrade Company", which swaps out cheap parts and installs V-Caps as well as other higher quality parts.
The also upgrade the internal wiring and insulation which is marginal, according to them.
These upgrades are supposed to push the amps to a new level sonically.
The cost is $1500 and is well worth it if what they claim is true.
In fact, they sell the upgraded versions of the amps as well as other Nuforce products (preamps, music server).
Currently they are working on my EAR 858 and if I like what I hear, will send in the Ref 18s as well--they would benefit from a little more body and warmth.
