I think this model is equal to the A-8690. Its integrated DAC is not too bad but has an enormous amount of bad soldering joints. I had to resolder almost 90% of it. Pay especially attention to the two massive copper distributor rails, the soldering pads on the PCB are too small to carry these rails, causing bad contacts.

As usual many bad soldering joints throughout the amp as with every vintage piece of equipment.

The MUTE- and MONO-switches are of poor quality. These are the horrible types where a push-action is translated into a movement perpendicular to it so they can mount the PCB with the switches flush behind the front panel. Even contactspray won't help. The only proper way to clean these switches is to take them apart which is a horrible job :0(.

This amplifier has an enormous power. Very tight control in the bass region.

The integrated DAC is easily outperformed by a modern DAC or CD-player.

Thumbs up for Onkyo.

Yes - its a big manufacturer and only boutique amps sound good...BUT this model Onkyo is a serious bit of listening. Don't be put off by the plain looks to sell appearance. Built in stereo DAC with 18 bit decoding which was arguably better then the early multi bit decoders means that with a decent input from a good transport this really flies above its weight. Direct paths for signals works well and a nice user friendly approach. Should have sold better then what it did but it was expensive costing more then a lot of pre - power systems - ie NAD/ Proton systems so it was never perceived as value. Found one on Ebay and not looked back. Rare as hens teeth.

Age considered, is reliable, has a wide frequency response and phono input with MM or MC.
Warm sound with JBL.
