I still have my Denon DP300f running with my Grado Green cartridge, but Denon has introduced a new pair of turntables as the next step. The DP 400 and DP 450 USB. The DP 450 USB has a USB port built into the base allowing you to record the music on a USB stick. The DP400 sells for $500 and the DP 450USB sells for $600. A key improvement from the DP300f is that both models now have an S styled tone arm which comes with a tone arm lock. Both units now have RCA jacks for audio output and the cables are not internallly connected. Both units have a built-in amplifier that can be switched on or off allowing you to connect to any type of amplifier or receiver. The only thing that I am not comfortable with is the plastic guard which lays on the platter and can then be used to support an album. I’m just old I guess and I prefer the standard dust cover which has hinges. I really am looking forward to seeing these babies in action!
