Well ... I guess I am wrong for assuming, but I do assume that EVERYTHING is always subject to system synergy. Having said that, the Cirrus speakers are the single best tool I have ever seen for component and wire evaluation. They are an open window, and PERFECTLY show every slightest change made upstream. So I am fortunate to have a system that does allow for very good evaluation.
I have no adgenda to bash digital amps, just a desire to see them improve.
I think we all might have a bit of "that" same centricity that our speakers (or other gear) is neutral and that it shows the distractions of all other gear, but I tend to think that is not always so.
I think most might offer that "switching" amps have exceptional highs (in the better ones) and if your speakers are not letting you hear that, then what does that tell us?
In the end, it is finding the components that sum to our preferences.
