I’ve checked the first 37 pages and found nothing about this unit.The site won’t let me search this circle. I’m seeking reviews and opinions on this multi-channel. I’m curious about its sound compared to the 4B cubed. It’s slim profile surprised me. I currently use Parasound’s A51 and wondering what sound improvements I would hear with the 875. The 4B sounded much better than P’s A21 driving Vienna Acoustics at a dealer. I am auditioning an Ohm Walsh 5.2 setup. So far I like them over a mix LM Fresco LCR and Aerial A. 5B surrounds plus one LM sub.
