I guess you could call this a vinyl-hypochondriac thread. In my signature you can see the current set-up I use. Importantly, my speakers are of the modern ported kind: http://www.system-audio.com/_en-GB/abou ... 230/SA1230
Let me start by saying I have not experienced any kind of woofer pumping, flapping sounds, weird buzzing, distortion exclusive to the speakers or any other kind of apparent problem. I simply - and probably unnecessarily - have the fear.
But I wanted to ask you guys to see what you thought. My NAD 3020i, according to the original 3020 specs, has 'ultrasonic filters' for both the inaudible/extreme high and low frequencies and this makes me think that there shouldn't be a problem. However, I wanted to get a second opinion in case people felt the NAD's filters weren't quite up to the level of protecting my speakers from long-term damage. If this is the case, I could get a phono pre-amp with built-in SS, like the Cambridge Audio 640p or something, and connect it to the CD/AUX input of my NAD. But if people think that would be overkill, it would be a small weight off my mind!
