Thiels to most ears are bright.I think harbeth for my prfernces even though I like hot speaker would be much beter especially in mids but throuight spectrum.Harbeth,Spendor,Quad along with some german designs like Audio Phsics have less coloration over the board and to me this includes Thiel.Spent a lot of time with Mac hooked up to the Thiel CS 7.Wish it had been 7.2 with Thiel made guts but don't think it would have made huge difference.It's your choicer maybe one only you can make but for me it would be harbeth hands down.
