I have the chance to buy a pair of Soundstream mono-blocks rated at 120w/8ohm-200W/4ohm for $400 and I was wondering if this would be a good choice to power a shiva based sono-sub. I'd be looking to wire the VCs in parallel and put 1 block to it for 200W into 4ohms. Does anyone here know if the soundstreams are a good quality amp? I can get 2 sets and run my mains, the sub and maybe my center with the 4 for only $800. Any opinions.
