Yamaha A-S301 vs Onkyo A-9150

Yamaha A-S301 review

When creating the equipment, ToP-ART technology was applied. Thanks to it, the sound output power is 60W (8 ohms) while Onkyo A-9150 has only 30W (8 ohms). And the sound quality is constantly growing up. The signal transmission is not affected in any way by noise or distortion. When creating the device parts of the highest quality were used. The built-in DAC allows you to receive digital audio from a DVD / BD player, satellite receiver or TV, and if you connect the optional YBA11 Bluetooth adapter to the amplifier (via the coaxial bus, the adapter has an appropriate output), you will be able to play files stored on your smartphone.

Onkyo A-9150 review

Onkyo A-9150 is equipped with a full-fledged phono stage, and not only for MM heads, which is very common in competitors' amplifiers, but also for MC pickups. The cartridge type switch is located on the front of the case. The phono stage itself, assembled on discrete elements, is placed on a separate board, while many manufacturers, in pursuit of a tick in the TTX, are often limited to one chip on a common amplifier board. Thus, Onkyo fully paid tribute to the analog audio format, which remains relevant for many audiophiles and music lovers today. Onkyo A-9150

Yamaha A-S301 pros & cons

Pros

  • The device will not be idle for more than 8 hours, it will go into standby mode
  • It is possible to turn off the tone, balance and loudness controls (Pure Direct mode)

Cons

  • The built-in DAC was a little disappointing: with a high-frequency response it produces a signal with a rather high THD

Onkyo A-9150 pros & cons

Pros

  • The bass remains clearly defined and resilient even at the bottom of the spectrum.
  • Gold-plated connectors are spaced far apart, which makes it easy to connect the thickest interconnects

Cons

  • No USB input for connecting to a computer
