Jtimothya, what Wittgenstein also said in the first page of the Tractatus Logico Philosophicus is:
"what can be said at all can be said clearly, and what we cannot talk about we must pass over in silence.
Thus the aim of the book is to draw a limit to thought, or rather--not to thought, but to the expression of thoughts: for in order to be able to draw a limit to thought, we should have to find both sides of the limit thinkable (i.e. we should have to be able to think what cannot be thought). It will therefore only be in language that the limit can be drawn, and what lies on the other side of the limit will simply be nonsense."
'tis all really rather confusin'! I do love the Ref 3, but will not comment about Act 2 as I haven't heard it (LW would be proud of me!). I can suggest though, that a fair comparison between the two should involve identical brands/models/lengths of ICs going in/out of the devices, only difference being RCA vs XLR. Furthermore, it is important that the Ref 3 be run in true balance mode, as it can operate also in single ended mode using XLR connectors, though the sound quality is in this submode and in any single ended configuration degraded.
