For the May 2019 "Glass Audio" special edition, audioXpress asked Erik Owen to share with us his experience with the new Nu:Tekt HA-K1 “Tube” headphone amplifier using the novel Korg Nutube 6P1 device. This interesting headphone amplifier is sold as a kit for $199, it's relatively easy to assemble, and - more interestingly - makes for a practical way to actually induce some of the magic of tubes in a relatively portable configuration.

For audioXpress May 2019 -Glass Audio Special - we’ve put together a very strong edition, with some of best tube experts sharing a series of DIY projects for all skill levels, from restoration projects to new amplifiers, preamps, and headphone amps. We review the Nu:Tekt HA-K1 headphone amplifier using the novel Korg Nutube 6P1 device, and interview the founder of Parks Audio.

This article provides an overview of the Korg Nutube 6P1, a new, miniature, low-power dual directly-heated triode device. It was developed by Korg (of musical instrument fame) and Noritake Itron, a manufacturer of vacuum fluorescent displays, in Japan. Although it is a true directly heated triode, it is manufactured differently than traditional vacuum tubes, which gives it some unique attributes. This article was originally published in audioXpress, May 2017.

With IFA fully occupying two exhibition areas, Europe's giant trade show for Consumer and Home Electronics was indeed a busy time for all technology companies and certainly for many of the key development platform vendors.
