Stands for Soliloquy 5.0 Monitors

These are sweet little speakers. I'm driving them with an ARC integrated (50 watts). My problem is with the selection for stands with them. I home auditioned them with some low-mass (unfilled) Sanus stands. The speakers sounded wonderful, warm and punchy and with very clean/sweet highs. I sent those stands back and purchased the custom Soliloquy high mass stands and filled them with sand. The deep bass is now extremely solid, but the mid-bass is reigned in and they sound a bit thin in the mid-range.
What stands are other Soliloquy 5.0 owners using.
Thanks!
