My research suggest that the Mark3 OT are a good value, and sound good, but are not Great. I was looking for Great OT's what ever that means.
Let me back up!
After building a very nice ST70 using Shannons board, I'm ready to build a truely GREAT set of mono blocks. Having poor luck finding the hand holding I need to do this I thought about loosely basing them on the Mark 3 as a guide, but with everything upgraded such as the Posiden driver, SDS PS or better? and better OT /PT all in larger custom cases.
Perhaps this is not the best route to take with the proformace level I want, but this path worked wonderfully with the ST 70 build.
Is there perhaps a better way to acheive "World Class" for a semi newbie? Moving up past the upgrade routine seems to require massive engineering and mathmatical skills.
