Nostalgia is strong with the Infinity IRS Vs. I know the gentleman who sold them and I didn't hear them in his room before he sold them some years back (they were disconnected and in a corner). I recall they did have some upgrades to the newer / better Xover components, maybe woofer amps too. I also heard the IRS V about 15 years ago. They sound effortless and big as one would expect but I forget the details of the sound being so many years ago (plus what to compare to at the time, I had Carver Amazings). I do recall asking my friend how they sounded as he had moved onto Wilson Alexandria XLFs and he said while the IRS V sounded big, bold, beautiful they didn't have the level of resolution of the Wilsons. I also recall him thinking they were a bit too big for his room which was 18 x 25 x 10 and seeing them in person I think he was right.
