Sonneteer Orton Integrated Amplifier

Sonneteer Orton

New for Summer 2014 the MK IV Orton which incorporates both an aesthetic upgrade and some circuit design upgrades, resulting in improved sound quality and looks.

MK IV now sports a fully machined aluminium and stainless steel remote control handset. Featuring polished stainless steel ball-buttons which are a mirrored feature on the amp's fascia. The handset, as well as aesthetic beauty, boasts an internal rechargeable battery and an LED torch light for that little extra help when trying to wire up the rear of the amplifier.

As difficult as ever as it is to improve on a much loved design we at Sonneteer are always looking to push the envelope. Thus the MK IV Orton was born. Taking the MK III Orton to a new more refined level of performance. The control system power supply (the Orton has three power supplies) has been improved with careful revisions and in conjunction with design changes to the circuit board mountings, all culminating to deliver pleasing improvements to an already highly regarded amplifier. In essence the "pin dropping" is just that much more real.

The Sonneteer Orton adopts a Dual mono power supply configuration which means each audio channel has its own, independent power source to maximise the purity of and control over the sound signal. On top of all of this the Orton has a separate power supply for all its control circuitry minimising its affect on the sound making part of the circuitry further ensuring the purity of all music that passes through it.

A fully integrated, dual mono, hifi separates' amplifier in the true purist tradition of esoteric, British high fidelity the Sonneteer Orton sits at the heart of the music system. Where using a Sonneteer CD player, music streamer, record player or even iPod doc the Orton delivers a truly musical experience that will captivate you senses for countless hours.
