The current "non plus" Prelude is an amazing speaker when paired with a good sub. I've had a pair for years and it's somewhat unique in the Silverline line (!) in that it has magnesium/aluminum woofers and tweeters, not shared with other Silverlines for reasons I find mysterious. The "Plus" has doped paper woofers with a silk dome tweeter which are fine (and I'm sure they sound great as do pretty much all the things Alan Yun designs), but the Prelude has the little screens on the metal tweeters that keep 'em "poke proofed," a feature I like. I use a tube amp and 2 REL subs (although they worked fine with one sub, I found another used REL and added it in the mix, thus making my "one sub" arguments less valid) with the Preludes, and lift them up about 4 inches on maple blocks (Vibrapods under the Preludes de-couple them from floor vibes and make them sound even better to my earballs) . My only quibble about the Preludes is the fact that they aren't cladded in a real wood veneer, but I suppose that keeps them at a certain price point. Maybe I'll get a cabinet maker to put a striped ebony veneer on 'em. Yun told me in a phone conversation (I thought I needed a woofer, but didn't) to single wire the Preludes for "more coherency"…his words…and he was right (I did try bi-wiring anyway, at which point I discovered for myself that single wiring was much righter).
