"It may very well be the last power supply upgrade you ever purchase."
-Digital Audio Review
"There is no stronger statement I can make than this: once I purchased my first PS-1, I’ve purchased no other power supplies (and I purchased a second PS-1; soon to be a third!). Sonically, they’re magnificent. The noise floor disappears, and they bring a clarity and richness that is unparalleled. I also love that there are four configurable outputs. Cost-wise, they’re very reasonable as compared to the alternatives. The convenience of one box when using multiple devices is not to be underestimated."

The modular PS-1 linear power supply is powerful, affordable and modular. Power up to four devices at once—it's the last power supply you'll ever need!
For DC powered devices, replacing the standard 'wall wart' switching mode power supply with a robust, quiet linear power supply can reap huge sonic benefits. For years, customers who purchased our award-winning "micro" products (Remedy, bLINK, µDAC, Recovery, etc.) have asked us if we also made a linear power supply to increase their performance, but our answer was always an unfortunate "no." No longer! The new PS-1 modular linear power supply is a truly innovative product at an affordable cost.
In the crowded world of linear power supply units, the modular design of the PS-1 is unique. Most power supplies are a fixed voltage and made to power a single product. Some power supplies offer dual (and in the rare instance, more than two) outputs with different voltages. A very rare number of power supplies offer more than one output AND allow the user to select the voltage. Typically, these power supplies are large, heavy and ridiculously expensive. And none, to our knowledge, are truly modular. Enter the PS-1.
- It's modular and user-friendly
The beauty of the new PS-1 starts with an emphasis on real value: it's modular design allows up to four devices to be powered at once, and they can even be different voltages! The PS-1 has four power zones in back. Each power zone holds a power module. Each power module can be set to one of four voltages (5v, 9v, 12v, 15v) and can power one device. To change the voltage, simply slide out the module, move the internal switch to the new voltage, and slide it back in. The front panel's LED display instantly tells you which zone(s) and voltages are in use. Additional power modules can be purchased as needed, ensuring that now and in the future, you won't have to worry about powering your devices.
- It's compact and affordable
The new PS-1 is just 6.25" x 8.25" x 3.25". Additionally, since it is made out of extremely sturdy but lightweight material, most of the weight comes from it's very robust R-core transformer. Compared to other power supplies the size and weight of some amplifiers, the compactness of the PS-1 makes it extremely easy to place and work with.
- It's awesome
The PS-1 offers real value and innovation. No longer do you need to pay hundreds of dollars (or more) for a power supply that only powers one device. The PS-1's modularity allows it to grow as your system does. Its price, performance level and real flexibility makes the PS-1 the new standard bearer in power supply units!
New HIgher-Current Module! (ETA June, 2017 — Pre-order yours today!)
We're pleased to announce the availability of new higher-current power modules. The new high-current modules will accommodate the same voltages (5, 9, 12 or 15v) but capable of up to 4A (instead of 1.2A for regular power modules).
The higher current module can facilitate up to 4A continuous current. This is the about the maximum current on tap for the PS-1 R-core transformer. Thus, if the product being powered requires 4A continuous current, no other modules should be used. However, it's important to take a look at the true power requirements of the unit(s) you're powering. Many times, the inrush current of turning a unit on is more than it's normal operating current. If this is the case, you may employ more modules on the PS-1—up to ~4A total maximum operating current. You can use up to four regular power modules or up to two high-current power modules per PS-1.
Due to significant cost increase in parts to produce the higher current module, pricing for the high current module is $500 each.
There are great reasons to consider a higher powered module. A lot of noise in an audio system is attributable to noisy power supplies or noise coming from outside sources or devices. The PS-1 effectively isolates and protects your system from that issue. Some uses for a higher current module:
- NAS drives
- Music streamers
- Network switches
- Anything needing up to 4A and 15v draw
Purchasing notes: The PS-1 base unit is $399, power module not included. Add power modules (one for each device you wish to power) from the 'Power modules' dropdown below. Each power module is user-selectable for 5, 9, 12 or 15v.
- Order up to four regular power modules for devices up to 1.2A each.
- Order one high-current module as long as max power draw is 4A or less
- Order one regular power module and one high-current power module as long as max power draw on the high current module is 3A or less
- Order two regular power modules and one high-current power module as long as max power draw on the high current module is 2A or less
- Order two high-current modules as long as max power draw on either is 2A or less
Each power module comes standard with one 1 meter long, 5.5mm (OD - outer diameter) x 2.1mm (ID - inner diameter) male barrel plug DC cable to connect your device. This is a very typical barrel plug size that fits most DC inputs, but please double check yours to be sure. Should you need to substitute for a cable with a 2.5mm (ID) connector, tell us how many you need to substitute using the "DC cable 2.1mm to 2.5mm" dropdown.
