The Sevenoaks sale doesn't officially start until this Saturday, December 12th, but you can grab an early bargain with all the sale offers revealed today here on whathifi.com. Full details here.
Must say, their sale is a damp squib. Most of the current stuff they are showing a pound off + HMV vouchers. The only substantial discounts in the hi-fi line are for defunct lines like Cyrus 6VS2/8VS2.
