I use the 2 box LS 36.5 dual mono pre with my Spectrons and they are great togther! They are not the PRemeir 7's but I'd imagine the synergy is still there. But, as a Modwright beta tester and public advocate I need to ask: what exactly is a "modified Modwright LS 36.5"? His pre is built from the ground up...what is being modified in yours?
