Here is what seems like a very fair-minded review of the SP-FS52 speakers:

"It's at this point in the review, given everything you've read, that you're expecting me to say that the $129.99 SP-FS52 are as good as (name your multi-thousand dollar speaker here). Well, as pleased as I am with the SP-FS52s, they're not going to upset loudspeakers costing $1,000 or more per pair. But those in the sub-$1,000 range should definitely take note. I feel that the SP-FS52 competes very favorably with the likes of Paradigm's new Monitor 7 loudspeaker at $898 a pair. Other worthy opponents include Aperion Audio's Intimus 4C ($275/ea) and possibly even the 6T ($695 each). Even HSU Research's fabulous monitor loudspeaker, the HB-1 MK2 at $298 per pair, would be in the crosshairs of the SP-FS52. I'm not saying that the SP-FS52 is the outright winner in any of these comparisons, but it is definitely in the same class when judging only sound quality. In terms of build quality and finish, all of the aforementioned options will destroy the Pioneer SP-FS52, especially the Aperion and Paradigm offerings, but then again, they don't cost $129.99, either. "
[edit: According to the Hsu website, the horn-loaded HB-1 MK2 monitors are $318/pr.]
While I do not trust Stereophile, or most of the other audio mags, on many of their equipment reviews, as they are subject to so much of the magic snake oil of the audio kingdom, I do put some faith in their speaker reviews. I've listened to speakers which have gotten good reviews there and found them to be generally on target.
Thus as they have praised both the earlier BS21 and the current BS22, I do put some stock in that. They wouldn't praise such a low priced product unless it sounded surprisingly good for the money.
Almost makes me want to pick up a pair. Except that I would have absolutely no use for them.
Got to hear both the bookshelf version and tower today at BB. I was rather impressed with both considering the price point.
They didn't sound quite as good as the Polks that were twice the price, but for the money, they are worth it. I thought the mids were a tad hazy, but then again, that's not the most conducive listening environment.
I know for at least the BS22, the sound of them in my own home was night and day vs in Best Buy. In fact the mid range is probably their biggest strength.
I also listened to the Polks at Best Buy (and have experience with some much nicer Polks). The Polks are more efficient, so when switching between them at Best Buy, the louder Polks sounded better to me, too. If there was one trade off made in the design of the Pioneer SP-BS22-LR it is the low efficiency (85dB/2.83V/m), but get them home in a better environment, drive them with a decent amp, give them a few hours to break in and they really start to shine.
My first SACDs arrived yesterday. I listened to Pink Floyd Dark Side of the Moon, Fleetwood Mac Rumors and The Eagles Hotel California downstairs through my Diatone DS-73s. Unfortunately, the Steely Dan Gaucho disc would not play on my Pioneer Elite 45A. I'll move the SACD player up stairs and give it a listen with the little Pioneers this weekend.
