ARC Reference 3 preamp: tube character?


I am seriously considering buying an ARC Reference 3 preamp to introduce an element of "tube sound" character into a SS system. I understand this preamp is somewhat transparent which is not necessarily a bad property, but is it so transparent that it would defeat my purposes? Lexicon LX-7 amp and Legacy Whisper speakers.
Thanks!

Been there,done that,got the T Shirt.The REF 3 was the most accomplished pre amp I have had the pleasure of owning.The only thing between you and the music is the air.
Anyone have an opportunity to compare the REF3 to one of the Atma-Sphere preamps? My instincts tell me they share a similar tonality, but I'd like to hear from those who have heard both.
