Wyetech Jade and TRL Dude

Please excuse this response since it does not really benefit your inquiry. I can comment on the Jade in comparison to a Shindo Aurieges. I preferred the Jade in my system. It presented an expansive soundstage while maintaining a SS signature. It relays a very neutral, precise representation of the source. The Shindo was amazing in its own right, but representative of tubed equipment in overall signature. Not bad by any means...after all, it would be my recommendation for any other pre when leaning towards a slightly less neutral impression. Read the 6moons review on the Jade and Opal...some really good information on these.

Gary, I have come to strictly accept neutrality in audio. Coloration is acceptable only for coloring books.

I certainly can agree with having a tube pre as a mandatory alternate requirement when a change of heart (sound) is warranted. Lately I have been enjoying my Audible Illusions L2 pre. It still amazes me how inexpensive this little gem is when $ VS. :) ratio is concerned. My Wyetech, on the other hand, just boggles my mind. You cannot even begin to define its signature. It is just...there. The absolute best of every single nuance of sound reproduction possible (IMHO). Silly good.
