AC2 Power Supply

Reference Level AC Voltage Power Supply Unit with built-in Super Conditioner module
The AC2 power supply is the reference level product in our AC PSU range, and is an excellent way to maximise the upgrade potential of any piece of equipment that requires a low-voltage AC supply, such as the Cambridge Audio DACmagic or the 540P/640P phono stages, and several Musical Fidelity components. See the bottom of this page for examples of compatible equipment - the list is not exhaustive. The standard power supply shipped with equipment is almost always a cheap nasty black plastic box that either plugs into a mains socket and obscures adjacent sockets, or sits on the floor humming away to itself. They very rarely have features such as shielding, or a half-decent audio grade transformer, or any form of mains filtering or surge protection, which all adds up to mean that you are effectively strangling the performance of your equipment without realising it.
 
Custom HiFi Cables to the rescue! We have developed a low-noise AC power supply, which uses a specifically designed mains filtering and surge suppression system, which we call our Super Conditioner module, as well as additional design features to further suppress any interference. It runs completely silently, and stays cool, at all times.
  
To power these units, we recommend the use of our PowerBlack IEC cable. The AC2 PSU is not supplied with an IEC power cable as standard - if desired, you can use a 'free' type (the sort that comes with various electrical equipment, most people seem to have several of these spare around their homes), or an upgraded cable from us for an enhanced listening experience.
 
This product comes with a 30-day money-back guarantee if you are not completely satisfied with it (terms and conditions apply)

We can supply either a red or a black output power cable, see the pictures below (if you do not request a colour, black is the standard colour):





Customer Testimonials
 

Hi, just a quick email to say thanks so much for this AC PSU, it's really superb, I have been listening to it this weekend and it's 'The Business'! I think its brilliant - it seems to run cool, its silent (which is more than I can say for the R*** A****** one) its a good size (fits easily under my tv cabinet) good quality connection - superb!

The introduction of your AC PSU into my system brought about significant performance improvements from all of the inputs on my Furutech DAC (phono, line and USB digital) via its analogue output. I haven’t yet tried to “record” an LP to my computer using its USB digital output but I’m sure the audible benefits will be there also. I’m also very pleased that the PSU is well built, quiet and cool running and at a very reasonable price. It has been an all round success, and I would have no quibbles about buying further devices from you or recommending that my friends try them.

I’m very happy with the AC PSU and PowerBlack IEC cable combo. What a difference a decent power source makes! I was impressed with the addition of the Speedbox II to the Pro-Ject turntable, where it took performance and the noise floor to a different level – now, with the addition of your AC1 PSU, it has stepped up performance to an even greater degree. I found because of the quieter background I could increase the volume, and couldn’t believe the clarity and the extra information now being heard. For the first time ever, I had the Bryston 4B ST protection lights glowing orange/red – momentarily – until I reduced the volume a little. So, I’ll have to watch that in future! Favourite albums, like Machine Head, Captain Fantastic and The Brown Dirt Cowboy never sounded so good! Even Nat King Cole sounded fabulous, although he always does. I hope your other customers are as happy as I am. I heartily recommend the addition of your PSUs. Well done, again!

Further Information
 
Our high-quality transformers are always specified far above the required power rating which ensures that they run cool, extending their lifespan and also meaning that they are much more capable of supplying large rushes of current when required, giving your music a much more open and expressive sound to it. This is all mounted inside an attractive aluminium case, with an optional power indicator LED (several colours available as standard, with others available to special order).
 
We custom-build each power supply to suit your particular voltage and current requirements - this information is usually printed on your existing power supply on on the back of the equipment, or in the manual, but if in doubt ask us and we can find out for you. A list of just a small selection of the products that we can power is given at the bottom of this page.
 
The rear panel of the power supply has a high quality IEC inlet with integrated power switch and fuse holder, and also the output socket with a removable output power cord (length can be specified by user) included with the supply.
 
The end power connector is also selected to be compatible with your equipment - in most cases, this will be either a 2.1mm or a 2.5mm DC 'tube type' connector, but we can get just about any type that you may need, including the 3 pin DIN type as used by Musical Fidelity. If you are unsure as to what you need then just ask!
 
The case is supplied in natural aluminium, but can be ordered in matt black if desired to special order. Additionally, the colour of the power LED can also be specified (if fitted).

This list is not definitive, if your product is not on the list then just contact us and we will be able to tell you the type of supply you need. The voltage and power ratings are given, along with the internal hole diameter and length of the DC 'tube type' power connector (or a different type is noted if required)
