ProAc D40Rs (original retail = $12,500 / Rosewood) on the Townshend Podiums in my 2nd-floor, wood-framed home. My impression is that they improve the bass resolution greatly and the overall image presents well at lower volume levels now.
That said, I think I’d consider the structure of the listening room before I’d worry about the price of the speakers. Not sure I’d use these in a basement listening room with concrete floors. Direct-coupling via spikes might work better in that situation. Or at least, be no worse (for less money).
