It's never easy to make recommendations without knowing exactly what the person who has paid the compliment of asking has actually heard.
NHT has been making speakers for some time, and PSB has too, so there are a lot of models on the market from these two makers alone, if you consider buying second-hand. They are not all bad. Perhaps you have heard some models in unsuccessful combinations.
IMHO there are some very interesting recommendations here. They strike me as coming from the horse's mouth : that is, the posters have heard what they are talking about. In turn, that gives you a lot to explore.
A wise audiophile once told me that the pleasure of audio was not in having wonderful music through great equipment. It is having wonderful music through great equipment *at bargain prices*.
It takes a long time and a lot of experience to build up the knowledge required to make the right decisions. I'm happy to share the little I know, and more important, I'm very lucky to have access to so much hard-won experience from others who know more than I do.
Perhaps you have not yet heard the kind of sound you would one day like to have. I think this is an essential part of the process. After you have this experience, you can listen to cheaper equipment and decide which of its weaknesses you can accept, and which you cannot live with. You are also able to state more clearly just what you are looking for.
No matter whether the suggestions here are gold or dross to you, in the last analysis you will have to make up your mind with your ears.
