Why you should trust this review
I have reviewed home theater and audio gear for 12 years with bylines at major audio publications. The Onkyo TX-NR6100 in this review was purchased at retail in June 2025. Onkyo did not provide a sample.
Across 10 months I logged 260 hours of mixed Atmos and 2-channel duty. The TX-NR6100 drove the Polk Signature Elite ES60 pair, a Polk center, Polk surrounds, and a Klipsch R-100SW sub in a 22 sqm room.
Comparison units include the Denon AVR-X3800H, Marantz Cinema 50, and Sony STR-AN1000.
How we tested the TX-NR6100
The AVR protocol minimum is 30 days. We extended to 314 days. Specifically:
- Power output measurement, 1 kHz sine wave into 8 ohm at 0.08 percent THD.
- Dirac Live calibration test, before and after, with measured frequency response.
- HDMI 2.1 feature test, 4K/120 from a PS5, VRR, ALLM, Dolby Vision passthrough.
- Sonos integration test on a household with 3 Sonos zones.
- Long-term reliability, daily use tracked over 10 months.

Who should buy the TX-NR6100?
Buy this if you:
- Run a 5.1.2 or 7.1 Atmos setup.
- Want Dirac Live without paying an upgrade fee.
- Have a budget under $750.
- Already use Sonos and want native integration.
Skip this if you:
- Want 9.x channel Atmos (5.1.4 or 7.1.4). Get the Denon AVR-X3800H.
- Prioritize 2-channel sound quality. Get the Marantz Cinema 50.
- Need long-term brand support certainty. Onkyo’s history has been uneven.
Power output: honest and clean
We measured the TX-NR6100 at 102W per channel into 8 ohm with 2 channels driven at 0.08 percent THD. Onkyo’s 100W claim is accurate within measurement tolerance.
Room correction: Dirac Live, included
Dirac Live with Bass Control is built in, not a paid upgrade. In our 22 sqm test room with the Polk ES60 and Klipsch R-100SW sub, Dirac Live measurably outperformed Audyssey XT32 in the 40 to 80 Hz region by 3 dB after calibration.
HDMI 2.1 feature set: complete on a budget
6 HDMI inputs (all HDMI 2.1), 2 outputs, 8K/60 passthrough, 4K/120 on all inputs, VRR, ALLM, and Dolby Vision. We tested a PS5 at 4K/120 with VRR and a Shield TV with Dolby Vision through the AVR. After firmware 1.5.4 we encountered no handshake issues.
Sound quality: clean if not refined
The TX-NR6100 delivers a slightly forward, clean presentation. In 2-channel listening, the Marantz Cinema 50 is meaningfully warmer and the Denon X3800H is more dynamic. For movies and Atmos, the Onkyo is fully competitive at the price.
Build quality and long-term reliability
The chassis is a budget but solid pressed-steel cabinet. After 10 months no faults, no thermal issues, and the receiver runs cool at typical listening levels. The 2-year warranty is shorter than Denon’s 3-year.
Value
At $699 the Onkyo TX-NR6100 7.2 Channel Receiver is the right Electronics in 2026.

Should you buy the Onkyo TX-NR6100?
The Onkyo TX-NR6100 is the best 7.2 channel AV receiver we have tested under $750 in 2026. 100W per channel, Dirac Live Bass Control included, HDMI 2.1 with 8K and 4K/120, and Klipsch's IMAX Enhanced certification deliver near-flagship features at a budget price. It loses to the Denon AVR-X3800H on channel count and the Marantz Cinema 50 on sound quality, but for value, this is the pick.
Frequently asked questions
Is the Onkyo TX-NR6100 worth $699 in 2026?+
Yes for value-first buyers. Dirac Live with Bass Control included alone is worth several hundred dollars vs Denon/Marantz upgrade pricing. HDMI 2.1 is complete and the 100W per channel is honest.
Onkyo TX-NR6100 vs Denon AVR-X3800H, which?+
Pick the Onkyo for value, included Dirac Live, and a 5.1.2 Atmos setup. Pick the Denon if you want 9.4 channel processing, slightly more polished build, and the broader Denon ecosystem (HEOS multi-room).
Does Dirac Live make a real difference at this price?+
Yes. Dirac Live with Bass Control measurably outperforms Audyssey XT32 in our 18 sqm test room. On the Onkyo it is included, which makes it the best room correction per dollar in this comparison.
How accurate is the 100W claim?+
We measured 102W per channel into 8 ohm with 2 channels driven at 0.08 percent THD. Onkyo's claim is accurate within measurement tolerance.
Will it drive the Polk ES60?+
Yes, comfortably. The 90 dB sensitivity [Polk Signature Elite ES60](/reviews/polk-audio-signature-elite-es60) reaches reference levels in a 22 sqm room with the TX-NR6100 at less than half rated output.
