I just got my signature mono's in last night. I am hooking them up right now and will keep you posted as to any conclusions I have. If they perform as well as everyone says then they will stay forever. Henry has been very nice to deal with to this point and very professional. I went ahead and purchased without hearing since I have the two week trial to return if I don't like them. How can you go wrong?
Although I must admit that the thought of buying an amp from a startup was somewhat scarry, but all of the big, well respected guys out there today were startups at some point. I mean, lets face it, I'm sure if you would have bought a pair of synergistic research cables when they first started out they would have sounded just as good and not cost $1000's. Now synergistic has to pay for advertising and has to pay the middle man too. This thought greatly put my mind at ease. Nothing ventured, nothing gained! You can pay $5500 now for this signature version or you can wait until the Stereophile "Class A" stamp is placed on them and pay $10,000.
