Pioneer VSX-LX503 Pros

It has very good sound quality, it also can expand to 11 channels with an external amp, it also includes the lowest jitter level in the sub $5000 category. On another plus, it uses the same DAC that’s used in many studios which means when you decide to update you don’t have to change much and it has a very good built-in phono stage.


It uses only global cut-off frequency for all speakers not to mention removal is too sparse. Through my journey in testing countless different models such as Yamaha, Sansui, Lexicon, Akai, Marantz, and Nakamichi I realized that out of all these brands’ Pioneer uses processors like the Nakamichi brand which is a bit of a downside for such a premium brand.
