That is, if you've been forced to walk everywhere you went your whole life, the ability to own and use a Yugo makes you think that it is a nice car. Then again, once you get into a Cadillac, Lincoln, Mercedes, etc... your thoughts and opinions of the Yugo might change a bit. It all becomes a matter of perspective. I'm not saying that you've only heard or own "Yugo's", but what i'm saying is that you might not have even had what you were using optimally set-up.Since i currently own over 20+ different amplifiers and have owned dozens more than that, some of them of the Phase Linear variety, i posted my thoughts based on that perspective. On top of that, i've actually measured the response of Phase amps when driven hard and their design shortcomings become quite evident. That is, their power supply and ( especially ) their lack of filter capacitance results in heavy duty voltage sag under heavy load. The end result is bass that lacks impact, definition and becomes quite "round" sounding overall. Much of this can be alleviated through modifications, but due to the lack of room in their chassis, even this turns into a more involved project than you initially thought it would be. As a side note, if your NAD lacks bass control and definition, the first place that i would look is with speaker placement, speaker cabling and the power supply of the amplifier. Two of these three variables are easily addressed and the third can be dealt with by someone that is willing to learn and can follow directions.
Having said that, your figures about "reasonable" spl's for the Ohm F's are right on the money. I did some testing of my F's and about the loudest that they will play are somewhere between appr 90 - 95 dB's as measured at the listening position. One may have to adjust volume up or down a bit depending on the average intensity of the music and the low frequency content. Obviously, "light-weight" music such as Classical works of "Chamber Music" can be played louder due to their lack of low frequency content, but then again, playing that type of recording at those levels typically sounds "out of place".
