So, I will be in a market for a MC cart with medium output. Only one I can find within (somewhat) reasonable price range is by ACE by Benz Micro, not that I can think of one at much higher price. I prefer not to go lower than 0.5mv. Why arent there more cart with 0.6-0.8mv output. Well maybe not 0.6 since the differnce is only about a decibal. Is there something less attractive about the design and its sound quality?
