Harbeth P3ESR metal tweeter

No it would not.

Where did you read that? I’ve owned a few Harbeths and I have never found the P3 to sizzle. As a matter of fact I like the P3s better than the other Harbeths that I have owned!!

I have read this in a number of different forums (Agon, AK, even the slanted HUG forum mentions degrees of sibilance). Thanks for letting me know that you have not experienced this. Do they require a large amount of power or are they easy to drive? thanks

I think any 50 watt amp is sufficient. They have a low sensitivity rating but they are easy to drive. What size room do you have?

They are easy to drive.They will play as loudly as you'd like with 50-60 watts.They won't have excess sibilance unless your speaker cables are a bad match.
