Based on StormAudio's award winning ISP Elite MK3 platform, the ISR Fusion 20 is a 20 channel processor integrating 16 channels of the latest Edge amplification technology from Danish based ICE Power, exhibiting extremely low noise and distortion levels with 150W (8ohm) per channel and up to 500W (8ohm) when bridged.

This unique receiver in the market has all the DSP power to decode all the latest immersive formats (Auro-3D, Dolby Atmos, DTS:X Pro, IMAX Enhanced) and enable postprocessing to optimise any speaker to any room straight out of the box. It includes the highest precision implementation of Dirac Live Active Room Treatment for easy and accurate room calibration, supports additionally up to 20 PEQs per channel and can drive up to four-way active crossovers and any number of subwoofers.

Based on the ISP Elite MK3 design, it delivers the same audio performance thanks to StormAudio proprietary analogue/digital hybrid volume adjustment that maximises the dynamic range for a more accurate, detailed, and dynamic reproduction of your movie soundtrack or your music playlists, perfectly rendered by the ICE Power amplification. The ISR Fusion 20 has a fixed architecture, but the upgradeability of the HDMI board remains possible whenever new upgrades are released. It currently supports HDMI2.1a/HDCP2.3 up to 8K/4K120 with HDR10+, HLG and Dolby Vision as well as ARC/eARC. 

The ISR Fusion 20 can be easily controlled by a variety of tools, ranging from the included IR remote control to home automation systems or the speaker configurator.

We are an approved retailer for all brands sold on our website, which means full manufacturers warranty and support as well as detailed product knowledge within our small business.

We use an inventory tracking system which states if item(s) are in stock and if not, what are the likely lead times.

Who do you use for delivery?

Our primary delivery agent is DPD. Where orders are shipped directly from Yorkshire AV, we always use DPD who offer a fabulous service at competitive rates.

If we drop ship (i.e. direct from the supplier) then the delivery agent is out of our control. It is generally DPD or UPS however - we rarely see other carriers used.

Selecting "Next Day" delivery does not mean you'll receive your item the next day in some cases. It's the next day from when the item(s) are in stock with us. If there is an urgent need then please contact a member of staff via the Live Chat or telephone (01757 826111) to check on live stock levels.

Certain product(s) are delayed in manufacturing due to semi-conductor shortages across the Globe. We'll keep you informed as to your order progress and a likely ETA once we get updates from the manufacturers.

Orders for items not in stock

Given the vast amount of variations of each product (e.g. AudioQuest cables) or Pro-Ject Audio Turntables - we keep the most common options in stock (i.e. gloss black finish, or 1.5m RCA cables) whereas longer cables or cables with terminations that are less frequently ordered will be ordered as required.

Generally speaking - we receive orders within 2-3 days for UK suppliers and 3-4 days for European suppliers (i.e. AudioQuest, DALI).
