Passive preamp for Tube Amp?

Has anyone tried using a passive pre with a tube amplifier? In particular I am interested in a passive like a Placette PVC with a McIntosh MC275. Primary source will be phono via a Rogue Stealth. Speakers are Quad 2805.

I have heard mixed reviews on whether this would result in softened dynamics and bass impact. Many of the published reviews of the Placette are very positive, but I have read some posts by actual users who mentioned the softened dynamics and weak bass.

The Placette comes with a 30 day home trial, but I am just looking for as much information up front as I can get. Thanks for any wisdom here...

Try a TVC, especially those that use S&B transformers like the Bent or K&K (which is the one I have). I've been using one with a 2V digital source, a phono stage with 64db of gain, and an amp with 67K input impedance. Amazing transparency, clarity, and soundstage. With a TVC you still need to pay attention to impedance matching, especially with the sources driving the TVC, but you have more flexibility than what most resistor based passives can offer.

Here is an interesting link that will help explain the impedance of a TVC:
