I have a pair of Denon Dn-s 3500 with a Beringher DX-7 4 Channel Mixer in a full structure coffin.
I have had these for under 2 years but they are all in full working order with no problems at all. It is still top of the range and i am the only that has laid hands on it
NOTE: There is one issue with the mixer...... The base nob on channel one was broken on very early transport but other than that its a sound system.
Delivery: Would prefere pick up but if not delivery can be organised with an additional cost
