Finally got the Richard Gray 600s. Works very nicely, so I'll get the QB8 then sell the QB4 on ebay. Thanks to all.
Keep or sell
I'm currently using a Nordost QB4 and need another out let on the box. I;m getting a Richard Gray 600 conditioner with 6 outlets. I'm going to link them both, then run the system with both, then without the Nordost to find out what sounds better. If I like the QB4 better just by itself, should I buy another QB4 or sell it on here and buy a QB8? I could resolve the problem by running the amp directly to the wall to free up a spot on the QB4. Thanks in advance.
