I have listened to many models in the JM Lab lineup, and always felt they were very good speakers. I think the budget you have set will determine the proper course for you.
The NAD and PSB models you have are also quality models I have spent time with Paul Barton, and have great respect for his designs and models. You could expand your investment in the PSB line and also not be disappointed.
There are many products to be considered, especially if your budget is generous. $3K allows you to shop for high quality, and NAD would be overwhelmed by models from Vecteur, Linn,YBA and SimAudio ( QC based companies I believe)
I think you are on the right track, and will not be disaapointed with your choice of either speaker.
