Today Marantz and Denon use
common engineering, software and key components for all price ranges of AVRs.. The higher end products are built in Japan, the mid to lower are built in Vietnam by a subcontractor.
Over the last several years both brands have hit hard times.. Resulting in significant financial losses, there are multiple reasons for the weak financial performance but the majority of trouble started about 6 years ago when Denon attempted to
build market share by expanding distribution. For many years Denon enjoyed an incredible market position for high-end, quality AVRs, they had many technical 1sts. But as their distribution expanded Denon
was originally positioned as a step-to profit brand for the AV specialists, unfortunately this expansion caused troubles for the AV specialists as the more aggressive price points driven by the expanded internet sellers destroyed the brand/profit positioning held by the AV specialist. Next the AV specialists largely dropped Denon as a brand, putting significant financial burden on Denon, resulting in having Denon only capable of selling the lower margin price/profit AVRs through the internet sellers. And as the AVRs got more complex, the internet sellers had little technical support offering only price.
Over the last few years Denon has worked hard to add discipline/control to their distribution channels and have had reasonable sucess with their CI series and by adding HEOS though they are paying a hefty royalty to Sonos.. But with the shrinking of the AV specialist channels this left little room for Marantz sales, so D&M decided Marantz needed to move their products higher up the market more toward the independents..
Fast forward to now..
Early last year, Bain Capital sold D&M to Boston-based Charlesbank Capital Partners. CCP is the owner of DEI Holdings, a division of which is Sound United LLC, parent company of Polk Audio, Definitive Technology, and Polk BOOM. Also DEI Holdings is in car security systems with brands like Direct & Viper. Though still early, D&M under the direction of Sound United has assembled & hired some talented, strategic capable product and marketing personnel, with many from Harman International. @ CEDIA 2018 they had a great, crowded booth with multiple new innovative products and appear to be back on track.. I hope they do well, the market needs them..
