Audes TT-1700DC

Audes TT-1700DC power conditioner – Two Transformers for a Silent, Pure System

The Audes TT-1700DC power conditioner is a high-end mains filter with two independent transformers and integrated DC blocker, developed by Estonian manufacturer Audes. TT stands for Twin Transformer: a 1500 VA transformer for power components and a 200 VA transformer for source components, each with four dedicated CEE 7/3 sockets. Thanks to these separate power groups, the Audes TT-1700DC power conditioner fully isolates power amplifiers from sensitive source components such as DACs and streamers.

Two Independent Power Groups Without Mutual Interference

The key advantage of the TT architecture is the complete electrical separation between both transformers. Interference from switch-mode power supplies in source components cannot reach the power amplifier. Conversely, the large current peaks of a power amplifier cannot disturb sensitive source components. The result is a pitch-black background with greater silence, detail and spatial depth in the sound.

Effective Filtering and DC Blocker

Both transformers act as low-pass filters, suppressing mains interference from dimmers, switch-mode power supplies and solar panels. The integrated DC blocker eliminates direct current components from the mains supply, preventing mechanical hum in transformers of connected components. All eight sockets are galvanically isolated from the external mains network.

Solid Build Quality from Estonia

The TT-1700DC is housed in a sturdy metal enclosure with rounded corners — the same design as the flagship DT-3600DC. Its weight of 30 kg reflects the quality of the internal components. The unit is fully designed and assembled in Estonia by Audes, a company that has been manufacturing transformers since 1935.

Frequently Asked Questions

What is the advantage of two transformers over one?

With two independent transformers, power amplifiers and source components are fully isolated from each other. Switch-mode power supplies in source components cannot disturb the power amplifier and vice versa. The result is a quieter, more detailed sound with greater dynamics.

Is the TT-1700DC technically identical to an ST-1500DC combined with an ST-200?

Yes. The combination of an ST-1500DC and an ST-200 is technically identical to the TT-1700DC. The difference is that the TT-1700DC integrates both transformers in a single enclosure with one mains connection.

Which systems is the TT-1700DC suited to?

The TT-1700DC is ideal for medium to large high-end systems where separation of power and source components is desired. It works equally well with solid-state and valve equipment.
