I'm interested to buy the Auditorium23 for Denon and the Auditorium23 cables at the total price of £ 499.
could you arrange the shipment to Italy stating the related costs?
For the payment, I prefer to use the wire bank transfer.
Although, DSP can't correct for fundamentally poor loudspeaker locations as HiFiWolf reports. It can make a fairly decent sounding system that bit better for the main listener, generally at the expense of it being that little worse outside the main listening area. For home hifi this is rarely a problem, as we mostly listen alone, or perhaps two people sitting close together. For larger areas it is definitely a problem, so tends not to be used, or indeed, needs something far more extensive than simple two-channel DSP.
I use DSP for equalisation and time alignment (and crossover) but don't use it for modal room correction as fortunately my in-room LF response is pretty decent without it. If it wasn't, then definitely I would try some DSP like the miniDSP unit mentioned. I was kindly lent a Trinnov unit to try, and I preferred the sound without.
