The Cabasse Egea's - This is difficult for me because my room is upstairs, carpeted and is a small room. These speakers just did not work with that combination. In my room with these speakers, there was no bass, no low end at all, only the mid-range and treble, horrible to hear. Now you can take care of that with a sub-woofer but when some one tells me that I will need to spend $4000.00 to get this pair of speakers and then after that I will have to let go of more money for a pair of sub-woofers, my interest in these speakers went completely out the window. In addition, the person that was trying to sell me these speakers, told me that I was clipping my current speakers and I do not like being treated as some one who is ignorant. You clip an amplifier, you do not clip a speaker and basically this person was only trying to make a sale, was very pushy and I flat out do not care for that garbage in any manner what so ever. Now a friend of mine has these speakers with the matching sub-woofers and she is completely happy with them. They worked for her. Basically, you will need to try them and judge for yourself. Since the Egea's, I have tried the JM Labs 926's, the Klipsch RF-7's and another brand (sold by Julian Turner of Sedonna Sound out of Austin, Texas) whose name I cannot remember and the JM Labs and the Klipsch's worked far better for me than the Cabasse Egea's.

As far as the question about the big iron tube amps - I cannot answer that question because almost all of my amplifiers are 9 to 11 watt triodes and cannot compare in power to what you own and use.

The best of luck to you.
