I'm the happy owner of S80.2 and S120 in white. Renovated by Dillen.
I'm listning to S80.2 on a daily basis connected to my Beomaster 6500. Even now the radio is on and they play wonderfull in the background.
They are well balanced but bass could be more present. Basically I use flat level but with bass on 1 it evens out a bit but sometimes its to much.
The Beovox S120 are really big sounding compared to S80.2. They are used with matching white BM6000 also renovated by Dillen. I have tried the combination of both pairs on the BM6000 and it sounds very big, balanced and puts the thought of the BM8000 in jeopardy.
The S/M120 is underrated but very great sounding. It was by chance I got mine. Orginial white to match the BM6000. S80.2 came first and S120 next when they S80.2 were at Dillen. He got them for me. I could not pass it up. Both pairs sounds great and I'm very happy with them.
