Adding on to his list of ‘world’s most expensive’ is the latest Bang & Olufsen Beosound 24ct gold & Diamond Edition. Exclusively designed by Stuart Hughes, this bespoke system is crowned as the most expensive music center, and the £1.2 million ($1,850,000) price tag certainly justifies it. Shaped out of 32 kilograms of solid 24ct gold, the system is also decked with 70 diamonds of 0.75 carats along with Aventurine and Topaz gemstones. The whole Beosound system, along with speakers, is plastered with a handmade solid gold veneer. Only five such units will be made, and make sure that you place your order much in advance as it takes about seven months to put up the Bang & Olufsen Beosound 24ct gold & Diamond Edition. Golden melodies doled out by this gold and diamond music system will certainly be a treat for audiophiles. For once, listeners can also enjoy the blinged visual extravagance too!
