Preamp $600-$1000


I have a an old Levinson amp I want to sweeten with a nice Tubed preamp and would like suggestions. I am currently using a Rotel 1070 pre and can certainly be improved on. I have been looking at Audio Research and Rogue any other suggestions? Remote would be nice but not a must.

Thanks for the suggestions guys. I just finished with a Manley Shrimp (still kinda hungry) haha. I will be looking out for others on the list next. I have heard huge differences so far and expect to hear more before I find the right one. The thrill is in the hunt....right? Or is it the proof in the pudding?
bat 3vki..goes for $750-$1300 depending on age and options... incedible sound, build quality, and reliable...
I talked to Paul at TAD and he said the TAD-150 can no longer be produced. He said that he will be coming out with two models to replace it: A buffered passive (TAD-100), and a pre more enhanced with tubes (TAD-250).
