I used a lower gain setting when I first setup the Sutherland and preferred the higher gain setting, but I took your advice and lowered the gain and at this point after many hours of breaking the lower gain sounded better and the soundstage filled out more.... always been on 100 ohms.
I've moved the turntable to seven different positions and it has the least interaction against the wall and near the sitting position and this might, in the end, be where it ends up, but that requires 4 meter interconnects, so I decided to go for very heavy rack with cones at each shelf resting on the next and I have a 3"thick tiger maple isolation stand on cones... rack weight, 5 sets of cones going to the floor, 108 pounds of integrated amp will be my first step and I will try the Townshend Podiums if that doesn't do it. I'll go long interconnects and wall mount as a last step if needed.
