I am still curious on one point... When considering amps and preamps, does one have more impact than the other on the sound we hear? Or are they equally responsible for the end result?
I also believe that the preamp highly affects the color or timbre of the system.
BUT, as Runnin points out, it is the amp that drives the speakers. The first part of putting together a system is matching the amp to the speaker, and since your spkrs have a low impedance, you may need a more powerful amp.
The resistance curve found on the left side shows that impedance drops to 3 ohms at 100 Hz and approx. 4 ohms from 1K to 4khz.

The specs on your amp show:
- 2 x 50W Continuous Power into 4 ohms and 8 ohms
- 100W, 150W, 200W IHF Dynamic power into 8, 4 and 2 ohms, respectively
I am not familiar with the design of the NAD, but it looks like it may possibly be enough power, but borderline IMO.
What do the other NAD owners think?
