I need half an AV amp! I have a multichannel audio amplifier (Arcam A85) as the hub of my system at present but I want to add an audio delay facility for two sources .It looks like the cheapest way to do this is to buy an AV amp/receiver with a variable delay built in and use this as a preamp to drive my current amp. I don't want or need a scaler and stand-alone (analogue) audio delays will cost more than many AV receivers! So I need an AV amp with 5.1 preouts and at least 150ms of adjustable audio delay. Obviously good sound quality would be a big advantage but the sources are freeview and a HD recorder so quality isn't as critical as with say DVD or CD. All I can find at the budget end of the market so far is the Yamaha RX-V657 or AX757, does anyone have any recommendations for auditioning?
