Everest Audio Labs' Ascent Server Goes All-Linear: Seven Regulators, a 320,000uF Reservoir and an OCXO Clock, About $8,970

Everest Audio Labs, a Polish manufacturer, has released the latest version of its Ascent music server — a fanless network server whose headline claim is not processing power or storage capacity but the way it feeds electricity to everything inside the case. The updated Ascent was shown publicly at the Audio Video Show in Warsaw in October 2026 and is described as available now, priced at about $8,970 (EUR 8,000) including VAT with the company's "USB One" interface card fitted.

Seven regulators and a 320,000uF reservoir

Most computers — including most purpose-built audio servers — run from a switching power supply, because switching is efficient, compact and cheap. Everest Audio Labs has gone the other way. According to the manufacturer, as reported by StereoNET and Positive Feedback, every standard ATX voltage rail inside the Ascent — +12V, +5V, +3.3V, +5VSB and -12V — is produced by linear regulation rather than by a switching stage. That takes seven independent linear regulators in total.

Feeding them is a shielded 250VA transformer, with 320,000uF of filtering capacitance behind it. That is a large reservoir by any standard, and it is the figure the company leans on hardest in describing the design. The stated rationale is the familiar one in this corner of the market: a switching supply generates high-frequency noise, that noise finds its way onto the rails, and the rails ultimately sit underneath the circuitry handling the audio data. Everest Audio Labs' answer is to remove the switching stage from the equation entirely rather than to filter its output.

It should be said plainly that these are the manufacturer's own design claims as relayed by the trade press. No measurements of noise, jitter or output have been published, and none of the outlets covering the launch has reported a listening verdict or any comparison with other servers.

USB One: a separate supply for the output stage

The second strand of the design is the proprietary USB One output stage, a PCIe card that handles the server's USB audio output. It runs from its own dedicated linear supply, backed by two 450F supercapacitors, which — again per the manufacturer — isolates the output stage from the main computer circuitry rather than sharing rails with the processor, memory and storage.

The USB One card is included in the quoted price when the Ascent is bought complete. Bought on its own, it is listed at about $900 (EUR 800). TechTimes additionally reports an oven-controlled crystal oscillator (OCXO) as the master clock — the type of clock that holds its own temperature steady so that frequency drift with ambient conditions is reduced.

The computer underneath

For all the attention paid to the power supply, the computing side of the Ascent is deliberately modest. It is built on an Intel N100 quad-core processor, with 16GB of RAM and a 500GB SSD for the system, plus provision for up to 8TB of additional internal storage for a local library. The N100 is a low-power part, which is what makes the rest of the design possible: passive cooling with no fan, and a current draw that a linear supply can realistically serve without the heat and bulk becoming unmanageable.

The chassis measures 430 x 353 x 109mm and the server weighs 13kg — a figure that says a good deal about where the mass is going. A transformer, a large bank of capacitors and a passive heatsinking arrangement account for far more of that weight than the computing hardware does.

Where it sits

The Ascent occupies a position that has become busier in recent years: the dedicated server, as distinct from the network streamer. A streamer typically receives a stream from elsewhere on the network — a NAS, a phone, a cloud service — and converts it for a DAC. A server of this kind holds the library itself, runs the playback software, and presents the result over USB to an external DAC. Listeners weighing one approach against the other are usually weighing self-containment and control of the playback chain against the simplicity of letting a general-purpose computer or NAS do the storage work.

What distinguishes the Ascent within that category is the thoroughness of the power-supply work relative to its price. Fully linear ATX rails are more commonly seen either in bespoke builds or considerably further up the price ladder. Whether that translates into audible benefit is exactly the question no published evidence currently answers — the coverage so far is a launch announcement, not a review.
