I had a chance to test and compare two very powerful receivers. This comparison will be interesting for people who look for a very powerful modern solution that has many additional features.
These solutions are 9 channel models, but the Pioneer VSX-LX503 vs Marantz SR6012 power comparison shows that the VSX-LX503 is more powerful – compare its 1090 W with 900 W that outputs the SR6012. Both models have 32-bit DACs installed, but the Pioneer’s solution uses the 384 kHz module when the SR6012 has the 192 kHz module installed. The SR6012 uses the HDAM technology for precise audio processing, while the VSX-LX503 works with the Sonos technology and it uses Phase Control and Reflex Optimizer. Both receivers use high-performance codecs to process various files fast.
These models support Wi-Fi and Bluetooth. The VSX-LX503 works with Chromecast applications and it supports the Google Assistant, while the SR6012 has the built-in HEOS technology and it is compatible with Alexa.
The SR6012 supports the dual-zone feature, while the VSX-LX503 supports 3 zones.
Some customers state that the SR6012 may have faulty HDMI boards installed – the customers get no output signal.
The VSX-LX503 uses MCACC and the SR6012 uses Audyssey for the automatic audio calibration. These receivers come with the calibration microphones. You can fine-tune the settings using a special menu.
The Marantz SR6012 vs Pioneer VSX-LX503 design features comparison shows that these two models have some common features – they both look minimalistic when the front flap is closed. They have large dials, a simple LCD display (the SR6012 has a small, round one) and a power on/off button. There are many additional buttons and some ports behind the front flap.
These models are provided with ergonomic remote controllers. Overall, these receivers are easy to control.
The dimensions are 15.2x17.2x7.3 in for the VSX-LX503 versus 15.3x17.3x6.3 in for the SR6012. The weight is 29 and 28 pounds respectively.
