I would definately sell the Martin Logans and keep the amp. A friend of mine owned Martin Logans and he much prefered the sound of my large efficient horn loaded speakers. Also these are the type of speakers (very revealing & efficient) that sound good with the slightly warm sound of Classe.
Upgrade amp or speakers?
I have Martin Logan Aerius i speakers, Classe Cp35 pre, Classe CA100 amp and Meridian 588 CD. I am looking to upgrade the pre/amp but don't want to spin my wheels ($$$) if the speakers are not worth the upgrade. the pre/amps I am looking at are the Pass x250.5, BAT vk-250 or ARC SD135. I tried tube ARC VS110 and loved the sound but it was a little too soft and moved music passages to the back. BTW, the speakers still sound great but am I over spending on the pre/amps? Thanks
