Sony STR-AN1000 vs Onkyo TX-NR6100: Sony uses compatible wireless rears, Onkyo adds a third 4K120 source

The short answer

Choose STR-AN1000 if compatible Sony wireless rear speakers solve your room layout. Choose TX-NR6100 for a third 4K120 input and a built-in MM phono stage. Both connect two HDMI displays and power seven main speakers, so those shared features do not decide the pair.

Before you choose

The reasoning and the trade-offs

Equal HDMI counts hide a one-device gaming gap

Three high-frame-rate sources use half of Onkyo's six inputs and fit directly. They exceed Sony's two suitable inputs by one. The remaining Sony sockets do not become 4K120 inputs through a setup choice.

What this is based on

NR6100: 3 of 6 inputs support 4K120. AN1000: 2 of 6. Three required fast sources leave a shortfall of 3 - 2 = 1 on Sony.

Main trade-off

Sony STR-AN1000

Its two 4K120 inputs are one short of a three-device gaming setup.

Main trade-off

Onkyo TX-NR6100

It does not offer the Sony SA-RS3S or SA-RS5 wireless-rear route.

What matters in practice

The differences that matter

Equal HDMI counts hide a one-device gaming gap

Three high-frame-rate sources use half of Onkyo's six inputs and fit directly. They exceed Sony's two suitable inputs by one. The remaining Sony sockets do not become 4K120 inputs through a setup choice.

How we reached this conclusion

NR6100: 3 of 6 inputs support 4K120. AN1000: 2 of 6. Three required fast sources leave a shortfall of 3 - 2 = 1 on Sony.

Two displays and vinyl can be a one-box job with Onkyo

Both cover the display connections. Onkyo also provides an MM phono input, so an MM turntable without a built-in stage does not need an extra phono box. Sony needs that stage elsewhere in the system.

How we reached this conclusion

Both list 2 HDMI outputs. NR6100 lists an MM phono input. STR-AN1000 provides analog line inputs but no phono input.

Neither preserves a conventional external front power amp

The US models lack full-range main-channel pre-outs. Subwoofer or zone outputs are not a substitute for volume-controlled front-channel outputs in the main surround system.

How we reached this conclusion

US NR6100 and STR-AN1000 connection records list no full-range main-channel pre-outs. Main front L/R pre-outs are required for this direct external-amplifier plan.

Your 5.1.2 layout needs 7 speaker channels. Your devices need 3 HDMI inputs, including 1 for 4K at 120Hz.

A powered subwoofer is separate from the speaker-channel count. This checks one main room. Zone 2, bi-amping and unusual speaker assignments need another manual check. Allow ventilation space and confirm HDMI settings, cables and speaker impedance before installing.

What you give up

Every choice has a cost

If you choose Sony STR-AN1000

  • A phono-only turntable needs an external stage.

If you choose Onkyo TX-NR6100

  • The US model lacks full-range main-channel pre-outs for a power amp.

Recommendation switch

The decision flips if...

I need Sony SA-RS3S or SA-RS5 rear compatibility

Choose Sony STR-AN1000. Sony documents that direct wireless-rear pairing.

A third 4K120 source or MM phono input matters

Choose Onkyo TX-NR6100. Onkyo supplies both connections.

I need full-range front pre-outs

Choose neither. Neither reviewed US model provides them.

What matters in practice

How to make the call

01

Use the rear-speaker plan to settle the Sony case

If routing speaker wire across the room is the central problem, Sony's supported wireless rear models deserve a close look. They still need a suitable power arrangement and their purchase cost belongs in the budget. Without that need, Onkyo's extra fast input and phono stage are easier benefits to use.

02

Check the input labels rather than the headline

Both product pages advertise modern HDMI support and six inputs. The manuals reveal that only two Sony inputs and three Onkyo inputs support 4K120. Match each gaming source to a documented socket before deciding that a receiver has enough room.

03

Keep a future amplifier in mind

Neither US model is a good direct match for an existing stereo power amp in the main system. If that is part of your plan, look for front pre-outs explicitly. A zone output or a powered speaker terminal does a different job and should not be treated as an equivalent connection.

Check these before buying

  • For Onkyo, verify the US TX-NR6100 rear panel rather than a different regional version.
  • Count fast HDMI devices, including a gaming PC.
  • Check that the turntable cartridge and output suit the MM phono input.

What this comparison cannot tell you

  • These are US connection and speaker-layout checks. We have not measured amplifier output, room-correction results or sound quality. HDMI format, firmware and display compatibility still need checking.
