Harbeth M30

I suggest that you post your question on the Harbeth Users Group - an excellent forum of harbeth users which is run by Alan Shaw, the speaker designer. If you go onto the Harbeth site, there's a link for the usergroup.

I would suggest you move away from the Naim equipment. I drove my Compact 7's with a 62/HiCap/140 for a number of years and then switched to ARC tube pre and solid state amp combo. Biggest improvement I have ever made to my system. The Naim does not have the power, dynamics and drive to bring out the best in the Harbeths. I believe the Monitor 30's are an even more difficult load than the C7 so your jump will be greater still. Sorry to the Naim crowd--I was one of you once. Hope this helps.

even upgrading your amp, i think you will find the sonic signiture of the m30's is still going to be quite different than that you are used to. its similar to moving from a rogers ls3/5 to a rogers studio 7. they are simply different. the synergy between the naim and the p3 is a bit on the magical side. completely satisfying. i've owned several different types of bbc derived designs over the last 20 years, and found them to all be remarkable to a degree.some combinations you will find just can't be topped for long term listening.
