I have a pair of older Genesis Genre I in a secondary system. They are sloped back, which should tip the soundstage up but I always felt the images were lower than natural. I put them on cinder blocks in my previous apartment and this did improve the sound in my opinion. I didn't import those cinder blocks to my new place so the Genesis speakers now sit on the floor and sometimes I'm keenly aware of they'd sound better if I put them back up on blocks. So, it can be beneficial in some circumstances.
