At the price so far there is nothing which does what the DL1608 does, UK price is indeed around 16.4% cheaper than an X32 Rack, my mistake. However that still represents nearly £200 difference and, for whatever reason, the DL does seem to be holding it's price over here.
I do get where you're coming from though, while the DL is a very good mixer, the X32 Rack is another very good mixer with a lot more facilities but at a higher price. If I was buying now I probably would buy the X32 Rack but the cost of selling my DL and buying an X32 Rack to replace it doesn't add up at present (and I don't need the extras the X32 has).
