Wow, got a lot of flak on this one. It is not the end of the world; I will just sell them if I dislike them or made a mistake.
To Mapman: will follow your prescription and see what happens. I am not sure about the usefulness of aiming the tweeters 2-3 ft to the side, but I will that a shot.
To Rrog, I owned a pair of GM Europas about 8 years ago. Very nice speaker, but was a bit bass shy; They also are expensive used and heavy to ship.( there is a pair on AG now or was) As far as Von Schweikert VR-1, there was a pair on AG about a month ago, but could not come to agreement on price with buyer.I am still not convinced that this is the best bookshelf value out there. BTW, I bought the Marimbas from an internet dealer who may have not have an official return policy, and he does not have another speaker in his inventory that interested me in my price range
MoFI, the Marimbas have about 7 hours on them, so I am far from Nirvana. 400-500 hours seems alot as recommended by Marak
I do appreciate everybody's commments and advice, but there are many speakers out there to consider as an alternative to my main speakers. Totem's Dreamcatcher; Rainmaker, and even the short floorstanders like the Arro and Stff models are viable choices.
The Epos 5i and 12i though discontinued seemed to be favored by Bob Reina of Stereophile. I believe I auditioned the original M-12 about 7 years ago, and was impressed by "how right they sounded" I don't have the opportunity of auditioning that many speakers in Honolulu because the 2 only high end dealers display 2K and above speakers because every turn must count to stay in business.
As MOFI noted there are many choices out there; manybe I should have spent a bit more money and bought the freakin VR-1. Nevertheless, I am having fun.
