Assuming you can even get a demo. Case in point; in November I booked a demo of the Q Acoustics 3050i home theatre system in the local (franchised) branch of a leading national UK chain. I did it online. I was then inundated with reminders. The allotted day arrived. I packed up my Arcam A19, boxed my DAC and stuck my laptop under my arm and away I went. As I parked up, I got another text reminder about my booking. You can imagine the surprise when I arrived at the door. "Appointment? You don't have an appointment" "Er, I do". "Er okay let me check. Ah yes, you do, but we can't do a demo because the demo room is full of stock" "You what, I booked this a fortnight ago" "You can demo it here on the shop floor, I just move these boxes out of the way" "But I want to hear the whole kit" "Er....we can't do that" "Okay" I then picked up my belongings and left. On to the next dealer. Rang them up "I'd like to hear the BW 603 S2 please" "Sorry we don't have a demo pair. I can sell you them though" "But I want to hear the home theatre kit" "No, we don't have any on demo, but I can sell you it if you want?" "I'm not going to spend over three grand on speakers without hearing them" "other people do..." "I'm not other people - what happens if were to buy them and I don't like them, can I bring them back?" "Yes, but there's a £500 restock fee". "you what?"
At that point, I gave up. My current Mission kit will do for another few years.
