In February this year my trusty Naim/Dynavector/Shaihinian system started to sound terribly distorted just at the frequency where electric guitars tend to frequent. 1500Hz perhaps, who knows. Anyway I originally thought that the amps needed some TLC so off they went to be serviced. They cam back just the same... I then went into my car to listen to the system in that and, lo and behold, the same problem. It had to be my ears. As syringing didn't do very much either I thought about buying some speakers that were perhaps less exciting. One of the great things abut early Arcs is that they can grab you by the throat. This is sometimes a good thing, sometimes not. To cut a very long story short I bought a pair of Dynaudio Heritage Specials a couple of months ago, thinking that they would be easier on the ear. And, yes of course they are an excellent speaker. But, they didn't really help actually as if you have a hearing problem at 1500Hz then you will have this problem whatever the speaker unless it has a massive dip at the point in the spectrum.....And, then of course they will sound terrible! The Arcs are now back in place (I am listening to less rock music currently!) and the Dynaudios are sitting forelornly. If anyone wants to have a piece of Dynaudio heritage at a saving over than the normal price then please PM me. They are numbered, receipted and fully legit. They have done perhaps 20 hours before I found that they didn't do the trick.
