FWIW, I wanted to let everyone know of a significant change (for the better) stand height made for my Omegas. I have a pair of Custom Shop Super Alnico monitors (7" Alnico) and have been listening for months on a custom pair of stands at 19". They sounded so good, I decided to sell my pair of Harbeth Super HL5 plus speakers. The stands were made for the Harbeths, but when sold, I sold the stands with them. I was then forced to use an old pair of 16" stands I hadn't used in a while thinking I would have to purchase a pair of Skylans eventually, but what a difference 3" of height made in my 12 x 20 room. All of a sudden, there was more body to the sound and much more evenness to the presentation. I was pleasantly surprised at how much better the speakers now sound. In terms of percentage, I would say at least 20% better. Keep in mind, my original set up at 19" made me sell my Harbeths which retail for over $7k.
I realize this may not work for everyone, but I wanted to share my experience.
