My dunlavy scV sound harsh

Class A solid state or high powered tube gear would be best.

We also know nothing about his room... the room acoustics can make or break a stereo. Even the best stereo in an average room will sound no better than so-so.

Can you share pictures of how your room is setup? My guess would be that is the main issue here.

Dunlavys need a VERY large room to breathe, especially the V's and the V1's. I would suspect that your up-line components are also NOT up to the task of driving the speakers well and frankly agree with the other posters.
If you have a VERY large room, maybe the amp is straining to drive the speakers resulting in distortion.

I have had the Dunlavy SC 5s in my reference system for about 10 years. Through this period I have upgraded and changed out componets and cables. Every step has been positive with the speakers accurately reflecting these changes. I once dropped a Phillips CD player into the system while the Audio Research unit was being repaired and it made the system unlistenable.

Overall, the Dunlavy speakers are the finest tools for listening that I have ever come accross in my 40+ years in this hobby. I have come to the conclusion that the speakers are pretty much absolute, with everything else being variable.

Ten replies and all seem to agree that harshness is not a normal Dunlavy trait. Doesn't mean that your tweeter isn't broken. Have you owned them for a while and, if so, is this something new?
