NAD Adds Dirac Live Bass Control To Its BluOS Streaming Amps

NAD Electronics is bringing Dirac Live Bass Control to select BluOS streaming amplifiers starting May 19, 2026, through BluOS version 4.16.6. The update applies to the NAD M33 V2, M10 V3, and C 658 BluOS Streaming DAC, with support also extending to previous generations of the M33 and M10.

This is a useful update because low-end control is where a lot of hi-fi rooms fall apart. You can buy great speakers, place them carefully, add a subwoofer, and still end up with uneven bass because the room is fighting the system. Some notes jump out, others disappear, and the whole setup can feel less balanced than the gear should allow.

Dirac Live Bass Control is built to address that exact problem.

Instead of treating the subwoofer as a simple add-on, it helps optimize how the low frequencies interact with the room, the main speakers, and the listening position. That is especially useful for people running modern streaming amplifiers in real living rooms, where perfect speaker placement and acoustic treatment are rarely realistic.

Better Bass For Real Listening Rooms

The appeal here is not louder bass. It is better-managed bass. A subwoofer can add depth and scale to a system, but it can also create problems if it is not integrated properly. Phase, timing, crossover behavior, room modes, and placement all affect how the low end arrives at the listener.

Dirac Live Bass Control gives supported NAD owners a more advanced way to tighten that relationship. It helps align the subwoofer with the rest of the system, which should make the low end feel less separated from the speakers and more connected to the music itself.

That matters for albums, films, games, and everyday streaming. When the bass is poorly integrated, the whole system can feel slower or less defined. When it is handled well, drums, bass guitar, synth lows, cinematic impacts, and room tone can sit with more control and less boom.

BluOS Keeps Older NAD Gear In The Conversation

The other important part of this announcement is product support. NAD is adding Dirac Live Bass Control to its newest premium streaming amplifiers, including the M33 V2 and M10 V3, and is also extending support to previous generations of the M33 and M10.

That is the kind of platform update that matters for people buying higher-end connected audio gear. Streaming amplifiers are no longer static boxes that do one job forever from launch day. BluOS gives NAD a way to improve products over time, and this update adds a meaningful room-correction feature without asking every owner to replace their amp.

The C 658 BluOS Streaming DAC also benefits, which makes the update relevant for users building systems around separate amplification rather than an all-in-one amp.

For NAD owners already using Dirac Live, this should feel like a natural next step. For anyone adding a subwoofer to a BluOS-based system, Dirac Live Bass Control could make setup less dependent on guesswork and repeated manual tweaking. It is the kind of update that sounds small on a spec sheet, but in the right room, it could make the whole system feel much better balanced.
