Which Passive Preamp --Bent Audio or Placette ?


I have been reading alot about passive preamps lately and the advantages and disadvantages of them.
I have read about resistor based volume controls such as the one on the Placette Passive, and transformer based volume controls such as the one on the Bent Audio NOH.
Has anyone owned or compared the Placette Passive Preamp and the Bent Audio NOH Passive preamp head-to-head?
If so, how do they compare sonically, and what are the sonic advantages and disadvantages in comparison to one another?
How does the passive Pass Labs Aleph, and the passive section of the Adcom GFP-750 compare to the Placette and the Bent Audio?
Thanks in advance!

I would like to add a Reference Line Preeminence One or Two to your short list. Of the 7 passive pre-amps I have heard, Reference Line is the best. It also betters any active pre-amp I have heard in my system in regards to depth of soundstage and transparancy. Also the dynamics are fast and equal to the best active pre-amps. I have not heard either the Bent or Placette. But a used Reference Line is considerably less in cost.
