Vic,
The turn-on/off relays have a minor low-level click to them if that is what you mean -- but it's so low in level that I can't see anyone objecting to it. Since you own the 9SE's already, the upgrade to V2 is highly recommended. Jason at NuForce believes that the standard Ref 9 V2 sounds better than the original Ref 9SE, FWIW.
NuForce is using a Zobel network on the outputs now that shouldn't be tampered with, but seems to work much better than the old parallel capacitor.
