TAD Reference 1, Rockport Altair, EA MM3

I have long debated on which speakers I want to buy and the price range I do not want to exceed.

For some strange reason there doesn´t seem to be a barrier that says stop purely on price ;)

A while ago I had the opportunity to listen to the TAD Reference 1 for a whole day in a shop here in Stockholm. That was certainly the best I've heard
in my life, but the price tag was beyond what I ever thought about paying for a high talker.

Now I have the chance to buy a demopar of these speakers and I am very eager to strike.

Is there any reason to hesitate and test around other speakers?

Two other speakers that has long interested me, but there is no chance for me to listen to are:

Rockport Altair
Evolution Acoustics MM3

The impression I got from what I've read is that they are certainly candidates as "the last speaker."

The Rockports Altair is not available in Sweden, just the models under. The MM3 doesn´t not sell in Sweden.

Does anyone possibly have listened to all three or TAD and any of the others that may come up with some suggestions?

Altair and MM3, I'm able to buy used.

Grateful for any input!

Have a nice weekend
