Who does not like the Lyra Dorian?

Just got one for my Linn LP12, and right off the detail was great, but it is very forward and bright. I am patiently waiting for it to warm up a bit so that I can make a real decision here, but I might suspect it is not to my taste (stress MIGHT, for I am known to misjudge these things in haste). I generally prefer a more spacious laid back sound, but the detail is seductive and it seems quite musical. I thought I would try something different, too firm an attachment to taste is questionable. Any thoughts?

By the way, I have Art Audio tube gear and Tetra speakers.
That was my experience too, though I did not listen to one with a huge number of hours on it, also on an LP12 as I recall. Cartridges in my experience only get a bit more lucid and warm as they break-in so I would encourage you to post after a time with your impressions should they change.
Try lowering the back end of the cart. until it breaks in. This usually will reduce brightness,
Only heard one once in a system I'd never heard before but it sounded exactly as you describe and the system owners eventually replaced it with a Denon DL-103(!).
