Thiel 1.5's with sound anchor stands?

Anyone have any experience with Thiel 1.5 on Sound Anchor Stands? Using them with Classe CA100 and room not the best but cannot rebuild the room. I don't know exactly how high they would raise them but it looks to be about 12 to 14" off the floor with spikes. Was wondering what that might do to the high frequency sound, being higher than ear level. help or hurt? These can be some very aggravating speakers sometimes, with some recordings, but some are stunning. I am new to this, so forgive me if I have not posted this right.

Thanks for any help. Brett
