I will tell you that your stands will make all the difference in the world with the Super HL5's. I'm not sure what you have those speakers sitting on but the bottom of the speakers needs to be sitting on something that has an open bottom. If you're in the U.S., check out resonantwoods.com. I have the Linear II stands and it made all the difference in the world. Don't listen to anyone on the Harbeth forum. They're very nice people but they've succumbed to brain washing. I used to own the C7 and went with their recommendation on stands and it was wrong. Once those speakers went onto a stand that wasn't a completely solid surface, they opened up to the point they sounded like a completely different speaker.
