Cambridge Audio DAC Magic Plus
Pros: Versatile, many user adjustable settings
Cons: None so far
I purchased the DMPlus to work alongside my MacMini. The MacMini has been stripped to just Mac OSX and Amarra Mini ver 2.4 using iTunes as the librarian. The Mini's USB output to the DMPlus is via an Audioquest Forest USB cable. I have 2 ways to listen to the DMPlus. First, I plug my Sennheiser HD650's directly into the headphone jack. In this mode the DMPlus acts as a headphone amplifier. iTunes and Amarra feed directly to the HD650's. The sound is wonderful and open. Great soundstage. You can see in your mind where each instrument is placed. The imaging is spot on...after you adjust the balance that is.
One of the pluses of the DMPlus is the user adjustability. There are 3 different slope settings to set to user preference. Also, you can choose between synchronous usb 1.1 or Asynchronous usb 2.0. The default is 1.1. You have to read the manual to see how to adjust this setting. Until you do the device will not be recognized as a usb 2.0 device by the computer.
Balance is another adjustment that is not labeled. You must hold down the Filter/Phase button and then the volume knob becomes the balance adjust. Release the button and the knob returns to a volume control.
Once the unit is dialed into your setting preferences it is ready for action. I have it's unbalanced RCA outputs connected to my Denon AVR-4311ci receiver so I can enjoy the DAC through my M&K S-150's. There are Balanced outputs as well if you have the equipment for it. The difference of the Mac Mini via Toslink to the receiver and the DMPlus via RCA is interesting and fun to A/B. The TosLink utilizes the Denon's AKM DAC's so this set up allows me to have my choice of DAC output.
Most of the time I find myself using the HD650's directly plugged into the DMPlus. It is a simple setup. Mac Mini as source, DMPlus as DAC/Preamp/Amp and HD650's as cans of choice.
Life is good! (and simple!)
