no volume control

Audio output impedance of dac is 50 ohms and input impedance of amplifiier is 33k ohms/1.0 volt.

Hi Sugar1. The 50 ohms drivability from your MF dac will easily drive the combined load the Lightspeed Attenuator and Rotel amp and the 1v sensitivity is also a great figure to have

Thanks for the information as I have been thinking about what direction to take to control the volume output as it seems so many directions to take and the lightspeed attenuator sounds like a good fit. I was looking to replicate sound to be somewhat in the middle between solid state and valve amplifcation. Could you verify this and also how to go about a purchase.
Thanks:

Sugar1, what a Lightspeed will do is give what your source (cdp, dac, etc) is giving out without anything added or subtracted, in other words it's like feeding your source directly into your poweramp, yet with control over the volume. It's like an open window to the rest of the system.
Most owners say it is more 3d, and extendeds the frequency at both ends (highs and lows) that is because it is direct coupled (good for the bass. And it's top end is almost to infinity (good for the highs) which become delicate and extended.
It is not for you if you if you want to add colourations to fix problems elswhere in the system.
