Any one with exp with this md . just gettin it and have always used a non-metered md . Sounds great in the manual but when I called White bout it and they told me yes it was good but a little unstable at times . Also the reviews that I read are 50/50 on this unit either you love it or hate it. Any advice would be helpful. Imfo needed the good the bad and the ulgy of the Quantum . Thx's gottit
