Who makes speakers with relaxed high freq.?

Very tricky, you want small, good bass and smooth!
Sonus Fabers family would be ok, used of course, spendors are ok....these are very general answers of course....but get a pair of Ribbon based speakers and dont come much smoother than that, dont get duped as well sometimes.

I tried the some chinese ribbon design and they were bad...like really bad, bright and brittle. So design choice is vital, try a pair of used Apogees, you will die and come back alive. Its that smooth and detailed. Never hard on the ears ever not matter what the recordings are, even the original Queen stuff sounds good so.....

Good luck

You have received excellent answers to your question as you asked it. There are other problems that can create harsh bright sounds coming from your speakers. Cd player/ preamp gain mismatch comes to mind. Not saying thats your problem but take your time and think about causes from all angles as the posters mentioning cables have inferred.

Spekers offering treble setup +-3 db. That should take care of it. BC Acoustic A series offer 5 tweeter settings, +3, +1.5, 0, -1.5, -3 dB..check the A1 and A2.5, maximum WAF too.

shoe, I have the same problem in my living room setup - bright room (room treatments out of the question!) and Adcom 555II amp which I tend to agree with the general consensus is on the bright side. I chose to look for new speakers and my two favorites for combined sound and looks were Vienna acoustics Bach Grand and Quad 22L. Dali Ikon 6 was a close third. I bought a pair of VA Bach Grands and am very happy with them. To my ears, soft dome tweeters are the way to go - more natural sounding and non-fatiguing in general.
