Pros & Cons
Onkyo TX-8020
VSPros
- It generates enough power to fill your room with 6-ohm speakers.
- The phono input is grounded. It excludes any noises.
- It features a subwoofer pre-out that makes the device flexible in terms of speaker options.
- The device turns off the amp, leaving the display active when it does not produce any sound.
Cons
- No switched AC outlet on the back.
- You cannot tune in individual stations using the stereo mode.
Harman Kardon HK 3770
VSPros
- The HK 3770 high current amplifier provides you with excellent control
- I like the Bluetooth function, which allows you to play music from my desktop computer in my office through an amplifier.
Cons
- After a few hours of listening to music (and I play music from the time I get up to the time I go to bed), it turns off, and I have to wander into another room and return it back.
