Bookshelf Speakers with the decent bass

The logical choice then to extend teh low end yet retain the would seem to be larger Focals in the same line.

The other affordable Focal line I have heard and like a lot is the Profile line. Check the specs, measurements reviews of particular models to identify the larger ones, most likely two larger floor standers rather than the smaller monitors, with more low end extension.

Sorry, I wouldn't want you to loose a sale.

"Any opinions on Fritzspeakers Carbon 7 SE Speakers.
Good reviews, but I don't know how they would sound with
the NAD."

The Fritz Carbon 7s would be an excellent choice, for way less than 4k. Fritz is a great guy to talk to as well.

I think Jl35 is right to wonder if you should consider more amp, if you are willing to go 4k on speakers. You might well be able to detectably best the NAD.

So you might think about how to allocate your budget. (eg, the Carbon 7s and a used Cronus Magnum -- to pick an amp at random -- come in at under 4 combined). I seem to swap out speakers much more frequently than my amps, so I might put more into the juice.

Kef R300's do bass, and everything else very well..
