I can't speaker for the burmester, but I can compare the Jeff Rowland and the Tact Preamp. The Jeff Rowland is much better by a huge margin, that being said if you Modify the TACT PowerSupply it is listenable (I bought one from aberdeen components otherwise I would have immediately sold the piece) but still not at the level of the Jeff Rowland. I still own my Tact but use it between a Theta Gen VII DAC/Pre. If you use the room correction and EQ functions see the Tact forum on yahoo, then it's worth using. If not get the Rowland.
I've heard the 001 into a VTL 7.5 and your CD player is an amazing player! But I did not hear the preamp section
