Wow, it's great to hear the impressions of others regarding this company's products. Last Fall, I took the leap of faith Trelja mentions and purchased a pair of Zu's Rune loudspeakers ($2,000) and have been very pleased with their performance. I also have Zu's Libtec speaker cable and Gede interconnects, which were a step up in all respects from what I had before.
Zu's products are well-designed and manufactured. When there is a problem - I had a pair of interconnects with a bad connection in one RCA that were replaced right away - customer service is excellent.
No affiliation other than being a satisfied customer.
