So far I prefer the Modwright to
Exemplar Exception 2
Thor TA 1000 MK2
CJ 17LS2
Supratek Chardoney
I have had many others, but in a leser price range, and all of the above are more $$$$.
I am waiting for a Dodd refence pre-amp to come my way, after Gary is done with the upgrades. Than I will send this one back to Dan for his..
Sorry I cannot help with the Calypso, but, for the $$$$, and the quality, I feel the MOdwright is just KICKASS good.
Good luck in your journey, and let us know whatcha do.
