Jh2os: I feel and share your pain man, sincerely!!!!! I will take a shot at your problem, may be right, may be wrong. As I have owned Cairn Fog, Arros and tested Prima Luna 1 for a week end, here is what I think: is it possible that you are missing the combination of an extra clean source passing information to a tube amp providing immediacy and midrange transparency to a neutral holographic speaker like few others?
May I suggest you pose for a second and reevaluate your choices and options? Ever since I sold Arros because of the popping woofer issue, I have been happy but never 100% content until I listened to Avalon speakers. Partnered with a tube amp with balls, they made me forget about Arros. $ for $, I would try (I know, there is no such thing as money back on used gear!):
- VTL IT85 tube magic yet no mellow.
- Avalon Symbol FL as you are a FL kind of guy. If they resolve like my Studio Pro and disappear even only 70% as good as the SP, you are in business! same feeling as before just better, deeper larger image and probably better resolution. 85w is more than enough to drive Symbols and you would be back to tube/holographic speakers. I have lost track of your source but stay away from the darker sources like Simaudio Equinox or the tube output ones, I find them boring after a while. Fianlly, if you want to add a HT component, there are different options with Avalon for center (symbol or LCR monitor).
A tube - Arros lover ought to stay tube-holographic system!!!!!
My 2 cents.
