Hi Leemaze -
Thanks for the response. You are right about the first response! I like your option about replacing the B1 with Wiim Pro. I had not even thought of that. I don't dislike my Audio Engine A5's - I just thought maybe the SVS would be a big jump.
BTW - My in bed listening is:
Wiim Mini connected to Topping DX3 Pro+ and HIFIMAN Sundara. I was thinking about changing the Wiim Mini and Topping to either a Bluesound Node or the new FIIO R7. What do you think?
