UnitiServePS - PSU for Naim UnitiServe

More Views


The UnitiServePS power supply replaces the small power supply that comes with the Naim UnitiServe, and provides significant improvement in sound quality.

The design is based on the experience gained with the TeddyCap family of power supplies for Naim Audio equipment, and uses the same technology.


In general, you’ll experience more clarity, tighter bass, more detail, better dynamics, natural voices, better soundstage and PRaT.

The UnitiServePS power supply is equipped with a high quality cable made of silver plated PTFE insulated wires. The cable capacitance is around 13pF/ft, and its resistance is also very low, around 10 milliohm/ft.


"Hi Teddy, thanks for the ps to Unitiserve that arrived Thursday afternoon. After 24 H it really makes a huge difference. More than I could dream of. Thanks again, and by the way my wife wonders if there is any other boxes you have that we still don't have, and that’s pretty amazing, right. Proves it's not just me wanting to hear the improvement."

"Just to let you know that my UnitiServe sounded exponentially better from the very first second of use of the new power supply (even before the unit had warmed up properly). Naim are really doing doing themselves a disservice by not supplying a better power unit with their UnitiServe."

"Hello Teddy Pardo I recently purchased a TP power supply for my Naim SSD drive. Its unbelievable the difference it has made to my Naim system, (let me say again, its totally out of this world the difference it has made) Its like listening to a whole new system. The music is so open, great base & so it goes on, I would throughly recommend it to any one out there wishing to get the greatest sound out of there Naim SSD system. Thank you Teddy Pardo for producing a truly great product. PS, Purchasing this Power Supply is a no brainer especially when you consider the cost of the unit."

"Dear Teddy, I thought you may be interested in an update regarding my two power supplies, now that they are fully settled in (UnitiServePS and Teddy12/2 for my Netgear netgear switch). I haven't compared and contrasted between the two. I just installed both and have run my system like that since.

My system is all naim: UnitiServe/NDS/555PSDR/552DR/500. The benefits are clear. An obvious further reduction of noise in the system, previously unrecognised. A sense of penetrating deeper into my CD collection. More detail, more realism. A significant and good value upgrade. It has surprised me how important the quality of the computer network is to achieving the best sound quality with a streamer. it's also amazing how much detail is trapped in a CD that can be revealed with system improvements.

A final point. I was very impressed with the quality of the two power supplies. The look, the feel, the packaging. A nice job. Thank you."

"I recently purchased your Teddy12/2 - 12V 2A Power Supply and couldn't be happier. I'm using it to power my DAC and have experienced a nice overall improvement in sound quality. Perhaps more of your products will be in my future. Just wanted to say thank you for a great product."

"Received the power supply for my Naim ssd recently. The difference is unbelievable, its like a whole new system for such a small price. Thanks so much for such a great up grade. 100% recommended."

"Je tenais à vous remercier pour la célérité avec laquelles vous m'avez envoyé l'alimentation.
J'en profite pour vous donner mes impressions d'écoute. Votre alimentation 12v est branché sur l’Unitiserve depuis 1 semaine.
Il était temps d’en faire un bilan.
Je viens d’effectuer 2 allers et retours entre une écoute avec l’alimentation naim d’origine et votre alimentation.
C’est comme si une Hicap était branchée sur l’Unitiserve.
L’écoute est bien plus présente, plus raffinée, des sons un peu magmatiques deviennent intelligibles, plus nets et compréhensibles, la scène est plus large. Le tout est plus impliquant, plus beau.
C’est un « audiblement » un nouvel échelon dans la montée en puissance de mon système.
Excellent rapport qualité/prix."

"I tested it very hard and listen a lot of music with it.
It works very well and changes sound better then before.
It is Awsome!!!
Improved focusing, calmed background and deepen staging depth.

Thank you for making good product."

"I have a ssd Naim ripper & recently bought from you the TP supply which is the greatest thing since sliced cheese."
