Yamaha AX-496 is a very good choice for beginners, and for people who want a powerful, musical, inexpensive stereo amplifier. When I first time heard the smaller brother (AX-396) of this amplifier, I was surprised how musical it is. I expected something „only for disco” sound, but I was wrong. These gears are lot better! :)
Suitable for all kind of music, and cheap loudspeakers with thin sidewalls can
produce more acceptable sound with this, than with other amplifiers.
Sounds almost like Marantz PM7001. But not so precise, and uses some cheaper parts. First of all DC offset is 6mV at the left channel, and 18 mv at the right channel, while the PM7001 has almost unmeasurable (0mV/0.5mV)!
Inside there are relatively high current (15A) output transistors, this may reduce the risk of output transistor failure. Buffer capacitors in power unit are coming from Nichicon, that’s fine, but they are a bit small (8200 mF) for a 100w amplifier. They should be at least 10000 mF, or 12000 mF.
The randomly working input selector knob is a serious problem of both AX-496 and AX-396. This is generally unacceptable, moreover Yamaha is a japanese brand!
But remote works well.
The tone control is better than conventional ones, but not as sophisticated as the Marantz PM7001.



Rating:

Sound: 9/10
Operation: 8/10
Functions: 10/10
Design, quality: 8/10
Remote: 8/10
Value for money: 10/10


Pro:

+ dynamic, musical, clear, silky sound
+ suitable for versatile speakers
+ stepless loudness
+ tone control is better than conventional
+ high current output transistors (15A)
+ doesn’t heat up, even at high volume
+ budget-priced

Contra:

- inaccurate, randomly working input selector knob
- I can see something strange low speed membrane movements at low basses, which is not from the music (feedback problem?)
- small buffer capacitor in the power unit (8200 mF)
- oversized housing
- average DC offset voltage
