Tim,
Yes, it is a tough call, and you offer good common sense advice. I may put this all on the back burner for a bit, because I am taking a short vacation at the end of September, and would resume the quest when I return
The Muse pre-amp has become a distant possibility for a few reasons which I need not go into. The low profile of both Muse and Coda concerns me less than not knowing what to expect. The key trigger for me is that what ever I choose advances the sound quality similar to the BAT-VK-200 amp which really opened my eyes about aspects of high end audio I either did not understand or appreciate.
Let me note, that the BAT pre-amps are a given as far as a possible choice. However, I was hoping to get something lighter in weight and smaller in size, and not dressed in "graveyard black". I did not talk to CJ today to clarify about the compatibility of their LS-18 pre-amp and the BAT amp.
One last point, I was thinking of launching a new thread about asking whether the electronic "design" of a component is still viable after say 15 years, that is, do newer designs necessarily provide better sound quality. I realize and know from experience that speaker design may be hardest to pin down, whereas electronics, and to a lesser degree cables over time "usually" ( I say usually) get better in sound quality incrementally. I know that the idea of buying some companies "newest" amp, pre-amp, CD player, etc. does not guarantee improved sound quality compared to either its previous models, or models of other manufacturer with similar dates of issue. That is an interesting question!!
Cheers!!
