what amps are you guys using for your for Dynaudio Confidence 20s?

I am running a pair of Sugden MPA-4 mono blocks. I traded my dealer My Confidence 20’s and some cash for his Confidence 30’s. What a huge improvement. The C20 is a fabulous speaker in every way, at the same time, the Huge floor stander brings out so much more of the music. Dynaudio Speakers, like high current amps. My mono blocks are 165 watt pure class A power.

I bought my 20's as 1 year old demo's from my dealer, and he bought a set of 30's. The new line of amps he was selling didn't seem to be able to run the 30's properly, so he called me 2 years later and asked if I wanted to upgrade to the 30's for a decent price, and he would take the 20's back. 

I was all over that deal, it took us 4 hours to get the 30's set up for the room, 13 feet x by 21 feet. But they are perfect. I was content to keep the 20's as my end game speaker, but I could not pass up on this deal. I am glad I did, the bass shakes my house now.

Oh it does for me, I am 61 yrs old now and I have reached the point of diminishing returns.😂
