NAD 3020Bwith Dynaudio speakers
I have a NAD 3020B which I use with a pair of Dynaudio Audience 50 speakers I bought about 11 years ago. When I bought the speakers I listened to them with some high power amps such as the Densen Beat 100 and Exposure. I've never really been able to get the same punchy sound with my NAD that I heard then. I tend to listen at lower volumes anyway, but feel I'm not really driving the Dynaudios enough - they're know to be a heavy load for an amp. However, many people have told me I'd be mad to change the NAD (and I must admit it would probably cost a lot to get something better).
One thing I wondered was whether to change the output on the amp from 8ohm to 4 ohm. I'm a little nervous as I don't want to blow the amp, but could anyone comment whether this woud be safe or give any improvement/changes
