Naim五月宣布更新全系电源（似乎不包括Flatcap和便宜的那个XP电源），全线电源改分立稳压。
主要是改了稳压方式，看naim官方论坛，最近几个月粉丝纷纷购买了新电源。
传说与旧款比较声音更开放，大幅提升清晰度和大场面控制力（不晓得会不会类似teddycap）。Hicap DR素质甚至能与supercap相提并论
。当然，粉丝都比较疯狂的，实际要听过才知道。
升级好像还没开始，要到11月后，今年购买的Hicap记得是170英镑，以前买的费用会比较贵。
Hicap DR售价没有变，新出产的hicap都是DR版本，后背会标明的。
The New Naim Discrete RegulatorMay 2012 Naim can today announce the completion of a two-year development project to design an improved voltage regulator to be used in its power supplies. The new Naim Discrete Regulator (DR) will be fitted to the HiCap, XPS, SuperCap, 552 PS and 555 PS power supplies as of May 14th 2012. The power supplies fitted with the new Discrete Regulator deliver a significant and repeatedly demonstrable performance increase.
Building on Naim’s upgrade path philosophy
The addition of outboard power supplies offers an established upgrade path for many Naim products. By improving the supplies themselves, removing the electromagnetic field of the transformer and interference generated by the rectifier diodes, and by eliminating transformer vibration from the product case, Naim power supplies offer improved sound quality.
The role of the regulator
Voltage regulators are widely deployed within Naim power supplies to ensure that audio and digital circuits operate with a stable, low noise supply voltage, thereby maximising their performance. Naim’s new discrete regulator betters industry standard monolithic voltage regulators and, even more importantly, has had its design and component selection refined in the listening room to deliver maximised sound quality from Naim’s audio circuits.
A pure development project
As well as incorporating the newly developed DR in these five power supplies, Naim has reviewed and optimised every aspect of their design. Transformer mounting, wire gauge, wire routing, mechanical decoupling, internal layout and reservoir capacitors have all been scrutinised to ensure that the DR’s benefits are fully realised. The result of the inclusion of the new DR regulators and the updates to design is a quite significant increase in performance which helps the listener to really connect with the artist and music.
Updating your product
Existing units can be updated but very few technicians outside of Naim’s Salisbury facility will be able to undertake this. Naim is offering a special reduced price to customers for updates to the new specification for power supplies that were shipped from Naim after 1st February (outside UK) and 1st March (in the UK). These units will be prioritised for updates in the first instance, however from October / November 2012 all existing units will be able to be updated. For more information on pricing and how to get your unit updated please contact your Naim retailer.
