be the best value now and in the future.

Stereophile has reviewed the PSB, and the Pioneer, and both came out well. You can do a search. Based on those reviews I would choose the Pioneer SP-BS41-LR myself. I got the impression that it had a little better bass, and the overall response was slightly better balanced, though it had slightly lower, below average sensitivity.

I didn't see any unbiased reviews of the Monitor Audio M2 in my quick look.
 

If you are thinking of resale value, I don't know how anyone can predict that.

The PSB Alpha B1 has had rave reviews from every magazine except the Rottweiler Quarterly, but I would only use them with a subwoofer because they don't go low enough to be used without one.

The Monitor Audio M2 would be my choice for sure, for best sound quality overall.

The Pioneer is not at all in the same league with the other two for sound quality.

Speaker Dilemma

Of the three bookshelf speakers below which would produce the best value for now and in future?

-PSB Alpha B1 ($250)

-Pioneer SP-BS41-LR ($150)

-Monitor Audio M2 ($300)

The Pioneer is the speaker from that group I would not care to listen to for very long. The others are much better-sounding IMO.

Usually no. Speakers are not like autmobiles that have yearly model changes.
