Does anyone have an opinion and/or experience with the Meridian G-57 200 watt amplifier? I have an opportunity to purchase one for what I think is a reasonable price. It's in mint condition and was recently checked and serviced by an authorized Meridian service center. It was given a clean bill of health. I have have a modest but nice NAD 1600 pre-amp/tuner. Speakers are JBL L100t and Dynaudio Audience 42's. I have been wanting a quality power amp for some time and this one may be it. Any information and opinions would be greatly appreciated, thanks.
