Well-reviewed Yamaha RXV-581 AV amplifier including Dolby Atmos.
Already quite keenly-priced at £349, but adding the code FLASH50 reduces it to £299, which looks to be the best price around currently. Deal should be valid until 20th March according to Richer Sounds website. Official RRP £499, although I don't think too many get sold at that price.
Free delivery (within 5 working days), or £4.99 for next working day. In-store collection also available.
