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...

I have yet to hear the Placette Active, although I would love to arrange an audition one day. As for the Placette Passive I find it works just fine for getting bass and midbass out of my vinyl through a Whest Phonostage.20 + MsU.20 phono preamplifier. But then again as I have said I have not yet heard what the Active version would do.
I am in a 30-day free trial using the Placette PVC with a Conrad Johnson MV60 tube amp. Sound is excellent, wonderful imaging. I am waiting for a CJ preamp to arrive so I can compare the two and make a decision during my trial period. With a 30-day trial, you have time to make comparisons in your home. If you buy the other preamps right, and decide to keep the Placette, resell them near the same price you paid.
Another excellent use for the RVC is to use it in line with your pre to give you 100s of volume level combinations, expecially when you have a stepped attenuator or a pre/amp combo with too much gain (e.g., CAT SL1) - a truly transparent device (which of course does not mean you enjoy listening to it as much as something else, even if not quite as transparent and uncolored).
