Onkyo A9555 Integrated Digital Stereo Amplifier Review

To sum this piece of kit up we have to say “Slightly retro Looks, but 100% 21st century sound”, the Onkyo A9555 has a very precise sound for an amp in its price range. The bass is fast and punchy but not at the expense of the top end which is crystal clear and has a decent amount of that indefinable “airyness” true audiophiles are after. It has great vocal detail and can project very large sound into big spaces.

In the original Japanese “On” means ’sound’ and “Kyo” translates as ‘harmony’, we have to agree in this case. If you are looking for a stereo amplifier in the $500 to $900 price range you will not find a better sounding unit.

Good points:

Great value, stands up well against amps up to 2 and 3 times the price
Elegant retro looks, and good overall build quality
lush “tube” sound that is forgiving and never harsh
Excellent mid range warmth
Full Punchy bassend
Good layout and easy to use front panel, also of good build quality
Well designed and functional remote

Bad points:

Occasional can sound a little too rolled off in the extreme high end. Very forgiveable at this price point.
No pre-out / main-in jacks or pre-out for a subwoofer.
