Steve Guttenberg writes: While Cowon's Plenue series of portable high-res music players may not be as well known as Astell & Kern's or FiiO's, I've thoroughly enjoyed the two previous Plenue models I've tested on this blog. This new Plenue D is smaller and more affordable than its siblings, and first impressions of its build and sound quality were extremely positive. I love the Plenue D's clean lines; it runs $299 in the US, £199 in the UK, and AU$429 in Australia.
