I agree with frogman's post. I've been listening to Maggies since I bought my MGI Imp back in 1980 ( still own that pair) but currently listening to 1.7's. I have owned and used a variety of high power SS amps ( Yamaha, Emotiva, Conrad Johnson) but my favorite by far is my current Jolida 502p with Tungsol KT 150 output tubes. It just sounds more realistic and full bodied than the SS amps I've tried and with 60 watts per channel is quite sufficient for my listening tastes. I've owned for 2 years now and frankly I have no desire to look elsewhere.
