I have a pair of MoFi Sourcepoint 888's, purchased on October 1st. I'm powering them with a McIntosh MC152 amp, and Anthem AVM 70 pre/processor, all balanced connections. Even though they can go fairly deep in the bass, I cross them over at 80Hz using (2) HSU and (1) SVS subs. The subs are strategically placed, all time aligned and calibrated with a miniDSP 2x4 HD. I know speakers are very room dependent, so my comments are just for my room and equipment. I'm in a 1,300 sq ft finished, insulated, carpeted basement. The 888's are about 10' apart, and I sit 12' in front of them. Now-a-days I mostly like to stream HiRes and DSD music, using a Roon One for a server, an EverSolo MDP-A8 Streamer using i2S output, and Denafrips Pontus 15th DAC.
The 888's are just awesome, all 96 lbs of them! I love the female voice characteristics, nice tight mid-bass, and accurate high's. They have very good vertical and horizontal dispersion. They play plenty loud when asked upon. At first I hooked them up to the 4 ohm tap on the MC152. During an AC/DC Thunderstruck listening demo I briefly saw my right MC152 Power Guard LED flash once. The average 888 ohm rating is 6 ohms. I switched to the MC152 8 ohm tap and have plenty of headroom for my listening, have never seen the Power Guards flash again. I very very seldom play this loud, but sometimes... if you know what I mean. I feel this is my endgame speaker, but you never know!
