This month sees the launch of the DR (discrete Regulator) to greatly enhance the performance of the Power Supplies, models: HiCap,XPS2,Supercap, 552PS and 555PS. See text from Naim’s site for full explanation.
I’m please to announce we are the first Audio-T store to have a DR specified product on demo in the form of the HiCap2 DR.
Like the XPS2DR we heard the other day (one on its way soon and sounded almost as good as an 555PS on our CDX2 Cd player though I can’t wait to hear how the DR improves the 555PS) the new HiCap is a truly astounding upgrade and has to heard to be believed.
I hope to be holding a ‘DR’ event nearer the time when Naim can offer upgrades to older units but in the meantime why not book a demo to hear it for yourselves. You are welcome to bring in your existing units to compare. And for those that really can’t wait until Oct/Nov there is always an option to part exchange your existing unit and have a shiny new one with a full 5 year warranty!
From Naim’s website:
“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”
