6. Amplifier

Onkyo TX-SR333	Pioneer VSX-LX303
5 channel Amplifier: Onkyo TX-SR333 features 5 channel power amplifier. It is rated at 65 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).	9 channel Direct Energy Amplifier: Pioneer VSX-LX303 features 9 channel power amplifier with Direct Energy design. It is rated at 100 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

WRAT (Wide Range Amp Technology): Onkyo TX-SR333 features Onkyo’s Wide Range Amp Technology (WRAT) circuit layout that prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image. If phase shift occurs and signal timing is not accurate, then neither is the resulting audio image.

Configurations without height channels: There are also other speaker configurations available which do not include height channels:

Onkyo TX-SR333: 5.1 with internal amplifier.

Pioneer VSX-LX303: 5.2, 7.2 with internal amplifier.

Bi-Amp: Pioneer VSX-LX303 is able to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

8. Immersive Audio Formats

Dolby Atmos

Pioneer VSX-LX303 supports Dolby Atmos.

Dolby Surround Upmixer: Pioneer VSX-LX303 supports Dolby Surround Upmixer. If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.

DTS:X

Pioneer VSX-LX303 supports DTS:X.

DTS Neural:X: Pioneer VSX-LX303 features DTS Neural:X which is an advanced upmixer that can take non DTS:X content and upmix it to the DTS:X speaker layout. It has replaced the DTS Neo family with improved flexibility.
DTS Dialog Control: Pioneer VSX-LX303 has DTS Dialog Control. This function adjusts the dialog levels during playback of the DTS:X stream. It allows you to separately increase the dialog levels in contrast with the background sound and hear dialog easily even under noisy circumstances.

9. HDMI

Onkyo TX-SR333 comes with 6 HDMI inputs. It has 1 output.

Pioneer VSX-LX303 comes with 7 HDMI inputs. It has 2 outputs which work parallelly and output the same signal.

4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p (YCbCr 4:2:0) video signal.
4K Upscaling on Pioneer VSX-LX303: It can upscale 1080p to 4K from HDMI and analog sources.
Analog To HDMI Upconversion: Pioneer VSX-LX303 supports analog to HDMI Upconversion, so you can input your analog video sources and output them digitally via HDMI. This means that you will need only one HDMI cable to connect to your TV.
BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35% (available on Pioneer VSX-LX303 only).
HDCP 2.-1 Copy Protection: Pioneer VSX-LX303 is HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
3D Ready: Both receivers are able to pass 3D video through HDMI.

HDR (High Dynamic Range)

Onkyo TX-SR333 does not support HDR.

Pioneer VSX-LX303 supports HDR10, Dolby Vision and Hybrid Log-Gamma. High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.
