Anyone try McCormack DNA + Placette Passive?

I am currently using a Promitheus Ref 4 TVC a with an older pair of passive friendly DNA-1 monoblocks. The Ref 4 is much better in every respect than either the McCormack TLC-1 or Endler resistor based volume controls I used previously. The Ref 4/McCormack seems to be a pretty nice combination to me. No problems with impedance mismatch, insufficient gain, or cable length with this option. I have rather insensitive speackers (Magneplanar 1.6) and rarely go beyond 1 o'clock on the volume. I would suggest you consider the Promitheus along with the Placette and Sonic Euphoria. These are all good values and resale should be good. One might do some A/B comparison and keep the best match in your system.

I have owned the Placette RVC, Placette Active, K&K SB102 -I now have a Bent TAP-X which is the newest version with using autoformers -- let's just say that if you are going to try a passive it should be given serious consideration. What has also worked very well in my system context (sensitive tube amps with high inout impedance) is the Goldpoint SA-1 stepped attenuator with a list price of $312. The transformer and autoformer passives do eliminate concerns of impedance matching and cable lenghts.

The DNA 125 has an input sensitivity of 1.0v so it should work well with a passive provided you have a good source.

I briefly tried a Placette passive with a DNA-1 Deluxe and it worked just fine. As someone noted earlier, make sure that your source has a reasonably low output impedance.

I personally found both the Placette Passive and Placette active to provide better resolution than a Bent unit. YMMV.

Had the DNA 0.5 Rev A (now with my sister) paired to a Bent Audio NOH TVC. Very musical combo!
