But is it HiFi? (Crown)

Possible amplifier for my Magnepan LRS?

Today's Score! I've been intrigued by the Crown professional Class D amplifiers. I kept waiting for the XLS1502 to go on sale or maybe I could find a used one reasonably priced. New they are currently $535. Which still seems like a value. Scanning Facebook Marketplace for "Crown Amplifier" I see a photo of what looks like a Crown XLS....But it is listed as a Crown "SLC" 1502.....Fortunately there was a picture of the rear and it clearly stated on the ID tag, XLS1502.........Buyer wasn't getting much action and had it down to $200!  And only a 15 minute drive away! Interesting amplifier with huge power and built in crossover and a few other features. Although not a true HIFI product, it is getting good reviews by the YouTube review crowd. Something to play with when I get back from an extended trip I leave on this Friday.

Pro amplfiiers like those from Crown are best paired with Yorkville speakers and other speakers that are more suitable for convention center/wedding events, live sound, DJing etc.

Such a power reserve is possible due to its Class D design topology.

Perhaps not a wire-with-gain, but it can still drive 2 channel hifi speakers. Although the movement of woofer(s), midrange cones, tweeters etc. or even a concentric design is better served by power amplifiers or a decent integrated amp. Think large filter capacitors and a big power transformer in Class A or Class A/B for 2 channel audio at home.
