Due to a move, I'm replacing my home surround sound system. I was looking for an AV amplifier and ended up acquiring three at the same time. After considering sound quality, ease of installation, and other factors, I'm putting the other two up for sale. Product Description This amplifier boasts features that are still top-of-the-line, including full support for "Dolby Pro Logic IIz," which enhances surround sound in the vertical direction by adding front high speakers above the front speakers, and the ability to listen to the radio streaming service "radiko.jp." It also supports video upscaling to a maximum resolution of 4K. Here are my impressions after comparing the sound: The sound quality is typically Pioneer-esque, with a brilliant and clear sound. Because of the high potential of the original amplifier, it delivers great sound that satisfies any genre. Furthermore, even if you can't install surround back or front high speakers, it has a virtual height (back) function that allows for 7.1ch, filling the space with a more immersive surround sound experience. To be honest, I also chose a Pioneer amplifier. If you're looking for an unrealistic system like Dolby Atmos, which requires speakers to be installed on the ceiling, this amplifier from this era, which supports front high speakers and is achievable in a typical home, might be a good option. ※ The remote control is not the one for this model. The volume control doesn't work, so consider it a bonus. However, the volume can be linked to the TV and works in conjunction with it, so I had almost no inconvenience using it. ※ Previously, I listed audio products, but due to a shipping accident, problems such as the sound not working occurred, causing inconvenience to the buyer and Mercari. ※ Audio products can be damaged by even slight vibrations.
