Deal is a bit complex but well worth it. Trounces all other £300 AV deals on the market.
The SR507 is currently for sale on their site for £200 but you must ask them to match their EB4y price which is £180. The Tannoy FX 5.1 sells for 130. It is advisable to collect from their Romford office to avoid paying their postage charges (a hefty £36 in all). Am on my way to collect mine..
Note that the Onkyo is a refurb that comes with one year warranty from Onkyo
