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 add another passive to this list: The Sonic Euphoria autoformer, which I recently bought and enjoy. While I have not compared this directly to a true transformer preamp like Bent, a well-designed autoformer is said to preserve bass dynamics a bit better. In any case, many prefer the sound of a 'former passive preamp over a resistor-based one. You can see reviews of the SE unit at www.onsoundandmusic.com (current issue) and also www.6moons.com/audioreviews/eelectric/preamps.html.
