Excellent,first time anybody has pointed out the difference between the crossovers...many who does not know that.Now I believe there can be a different sonic signature between the speakers( I suppose the finish can also have a small effect)
Now, staying with the question and with my suggestion,..have you ever auditioned Merlin speakers ??
Now,a bit of topic but relevant to the whole discussion forum...do you feel that the Signature 805 speakers are perhaps better suited to powerful ss pre/powers like your Classe gear,compared to the Hybrid DK amp ? Can this perhaps explain the results of your DK review ? Lets turn the question around....If you perhaps had the Merlins as speakers(which are known to work well with tube /hybrid amps) do you think the results obtained with the DK amp could have been more positive? I think this may explain some results obtained.
