German high-end specialist T+A has taken the covers off the T+A PS 3100 HV, a dedicated external power supply built to sit alongside the A 3100 HV stereo power amplifier and the PA 3100 HV integrated amplifier. T+A calls it reference-class, and positions the T+A PS 3100 HV as the visual and technical capstone of its HV series 3100 lineup.
Splitting the Power Duties
Connected to either amplifier via T+A’s M-23 Special Powerlink cable, the T+A PS 3100 HV divides the workload in two. The amplifier’s own internal supply then handles only the input stages and high-voltage circuitry, while the external unit exclusively feeds the output stages. T+A argues that this isolation keeps the amplifier’s character clear of interference even when driving a difficult loudspeaker load.
Reserves to Spare
Behind that claim sits a 1200 VA transformer paired with, according to T+A, twice the filter capacitance of the amplifier’s own internal supply: 24 custom capacitors totalling 240,000 µF, wired in parallel to keep internal resistance and inductance low. T+A quotes energy reserves of up to 1200 Joules for the T+A PS 3100 HV. Charging a capacitor bank of that size from cold could strain the components and trip a household breaker, so an onboard processor limits the initial current draw and ramps the voltages up in stages instead.
A VU Meter Built to Match
Visually, the T+A PS 3100 HV was designed to mirror the A 3100 HV exactly, right down to a redesigned, large-format VU meter on the front panel. It can be switched between two readings: the stability of the incoming supply voltage, or the current being delivered to the output stages in real time — turning the T+A PS 3100 HV into a genuine system gauge rather than a purely decorative element. The unit builds on the existing HV series family that already includes the T+A SDV 3100 HV streaming DAC preamp, reinforcing the 3100 range as a fully matched reference system.
Build and Finish
The T+A PS 3100 HV measures 17 x 46 x 46 cm and weighs a substantial 38 kg. Mains draw is rated at 1800 W, with standby consumption kept below 0.5 W. Buyers can choose between a silver or titanium lacquer finish, both fitted with a black ventilation grille cover to match the rest of the HV series.
Who Is the T+A PS 3100 HV For?
A separate power supply of this scale is squarely aimed at owners who have already committed to the A 3100 HV or PA 3100 HV and want to push the platform further, rather than newcomers shopping for a first HV series amplifier. It is the kind of upgrade path that reference-audio brands like T+A tend to reserve for their most demanding customers: system builders chasing the last increment of control over difficult loudspeaker loads, and listeners who want their electronics to look as considered as they sound. At $19,490 or €13,900, the T+A PS 3100 HV is priced as an add-on for an already substantial system rather than a standalone purchase.
