Quad Artera Mono Power Amplifier (Single)

At the heart of the Artera Mono’s design lies QUAD’s patented current dumping technology, originally developed by the company’s legendary founder, Peter Walker. In this sophisticated circuit, a high-quality, low-power Class AB amplifier handles the signal’s finer details, while a powerful current-dumping stage maintains speaker control with precision and authority. This approach eliminates common amplifier issues such as crossover distortion, thermal tracking, and the need for tight transistor matching. As a result, the circuit requires no internal alignment or adjustments, and it allows greater flexibility in the choice of power transistors.

True to Peter Walker’s famous philosophy that the ideal amplifier would be “a piece of wire with gain,” QUAD designs always prioritise signal purity. The Artera Mono exemplifies this ideal by incorporating OCC (Ohno Continuous Cast) cabling at its output stage, elevating performance to a new level.

OCC technology, developed to resolve annealing and grain boundary issues in copper and silver, uses a specialised casting process that produces a single crystal structure up to 125 meters long. This uninterrupted crystalline path allows for optimal signal transmission with minimal interference from impurities or oxides—far outperforming conventional materials.

By contrast, the commonly used OFC (Oxygen Free Copper), while effective, still contains roughly 400 crystal boundaries per foot and an oxygen content of around 10 ppm. These factors inherently limit its conductivity and signal integrity. With OCC, the Artera Mono ensures a purer, more accurate output signal.

Delivering a robust 300 watts per channel into 8 ohms, the QUAD Artera Mono is engineered to drive even the most demanding speaker systems. It features instant overload recovery and comprehensive protection—without relying on output fuses or relays. Despite its power, the amplifier exerts control with grace and finesse, prioritising musicality over brute force.

We endeavour to despatch same day for orders placed up to 1pm on available stock items (items with stock message "Usually dispatched within 24 hours"). Please remember to check with us first for a physical stock check if next day delivery is important to you. Any items with stock message "Usually dispatched within 72 hours" are items that we do not hold in stock but order in from the importer or manufacturer as soon as a customer order is received. Occasionally these may be delayed beyond 72 hours due to importer/manufacturer stock levels but we will inform you as soon as we can if this is the case.

UK Orders

We despatch the bulk of our UK mainland items on a 24 hour service – Free of Charge.  Non Mainland locations - Isle of Man, Isle of Wight, the Scilly Isles, the Scottish highlands and Islands, the Channel Islands and Northern Ireland may take a day or so longer and are not Free of Charge. Smaller items are delivered using Royal Mail 24 or special delivery. Larger items are delivered using a courier service such as DPD or UPS.

International Orders:

Due to the nature of our products and brand restrictions we are only able to send certain items internationally. Smaller items are delivered using Royal Mail Small Packets Airmail with International Tracked and/or Signed depending on value of item and availability of the service. Larger International shipments are sent by insured and tracked services using UPS. If there are any delays due to specific customs regulations, etc, you will be contacted by Hifisound or by the courier with a request for any further information required. Customs duties can apply for shipments to any countries outside of the UK depending on where the product you have bought is made. Customers are responsible for all taxes and duties incurred when the items enter their country.

Collect in Store or Home Install

At the request of the manufacturer some items cannot be supplied by mail order but you can click and buy them and then elect to collect them from our store or arrange a home install (if applicable). Applicable items clearly state that they are Collect in store or home install. Once ordered you will receive a message prompting you to contact us by phone or email to arrange for us to deliver and install or to reserve and collect from our store at your convenience, you will also be advised of the delivery time / stock availability as not all Home install / collect in store items are held in stock.
