AM Audio 833S Mono Amplifiers

The high-end of Hi-Fi can be pretty hit and miss between art, true high-fidelity sound reproduction, and inflated price tags pushing upwards of the cost of an exotic car. One Australian distributor aims to buck the trend however, and he has done so representing brands such as Opera-Consonance, AM Audio, and of course his own world-famous brand, Osborn Loudspeakers.

AM Audio (previously "Stereo Knight"), is a relatively new player on the market heralding from China where we're now seeing more and more products of exceptional quality and performance. Fang, product designer and owner of AM Audio is no stranger to high quality audio however. Working away for over 20 years in his search for audio perfection, now going it alone in his new venture he's now able to realise his designs and build products he believes are truly 'world-cass'.

Their flagship amplifier, the 833S is a mono amplifier by design with nothing spared or sacrifed in design. Standing nearly half a meter tall and 75kg each, the construction quality is incredible.

Using the 833 valve in Pure Class A, Single Ended configuration, they produce an impressive 140 watts per channel. Both the amplifier and the power supply sections are isolated to reduce magnetic field interference from the two massive power transformers, thus ensuring that only pure power is supplied to the amplifier. The signal circuit is direct coupled and transformer coupled, eliminating capacitors from the signal path to avoid any compression of the dynamic range.

According to Australian distributor, Greg Osborn, "both the drive and output transformers both use a very complicated winding technique and are constructed of special magnetic materials so that a bandwidth of 10Hz- 120KHz is achieved."

AM Audio 833S Mono Amplifiers"The attention to detail and lack of compromises results in an exceptionally musical and stunningly clear sound reproduction, that makes it easily the best amplifier I have ever heard." he continued.

What's equally impressive, and a topic we touch on fairly regularly is worldwide pricing, in particular 'price parity'. In Europe the AM Audio 833S Mono Amplifiers retail for $44,000 AUD, however due to Osborn's lean business model, in Australia the same amplifiers can be purchased for just $21,250 RRP.

But that's not the kicker. Osborn uses the AM Audio 833S exclusively in his own reference system, and as he's upgraded to the 'Ultimate Silver' Version ($24,250 RRP), just one pair of ex-demo 833S' are available right now for $16,400 (plus freight).

We're certainly impressed and welcome Osborn Loudspeakers' approach to pricing.

applause awards

Each time StereoNET reviews a product, it is considered for an Applause Award. Winning one marks it out as a design of great quality and distinction – a special product in its class, on the grounds of either performance, value for money, or usually both.

Applause Awards are personally issued by StereoNET’s global Editor-in-Chief, David Price – who has over three decades of experience reviewing hi-fi products at the highest level – after consulting with our senior editorial team. They are not automatically given with all reviews, nor can manufacturers purchase them.

The StereoNET editorial team includes some of the world’s most experienced and respected hi-fi journalists with a vast wealth of knowledge. Some have edited popular English language hi-fi magazines, and others have been senior contributors to famous audio journals stretching back to the late 1970s. And we also employ professional IT and home theatre specialists who work at the cutting edge of today’s technology.

We believe that no other online hi-fi and home cinema resource offers such expert knowledge, so when StereoNET gives an Applause Award, it is a trustworthy hallmark of quality. Receiving such an award is the prerequisite to becoming eligible for our annual Product of the Year awards, awarded only to the finest designs in their respective categories. Buyers of hi-fi, home cinema, and headphones can be sure that a StereoNET Applause Award winner is worthy of your most serious attention.
