NHTs & Pioneers were my first real speakers. I thought they sounded great.
Since then I have listened to a lot more speakers ranging from $600/pr to $23,000/pr MSRP.
And the really funny thing is, I think most of these speakers sound kind of alike

; most of them sound pretty good.
I think the OP did very very well getting the $12K Infinity Prelude Forty for $5K.
I suppose he could have gotten the Philharmonic speakers or so many other speaker for the similar price.
But in the end, they all sound pretty darn good.
