The entire iFi rack setup consists of: iCAN SE, iTUBE, iDAC2, iUSB3.0, Gemini, and iRack
iRack: “The iRack is certainly a good home for the iFi components. Well, it was kind of designed for that. Each component of the Micro series is just slightly longer than the iRack, allowing for the front and back plates of the chassis to lock into place nicely on the rack, preventing it from slipping”
Gemini USB cable: “The basic principle of the Gemini cable and iFi’s iUSB3.0 is to separate the audio signal from the power source”
Micros: “Breaking it down, I think the iDAC2 and iCAN SE are strong performers with good value. These are products I can recommend with relative ease. At 650 for the combo, you get solid performance with some versatility in a small package. The iDAC2, especially, is a good DAC at the 350 price point, and the included headphone amplifier is just icing on the cake. The iUSB3.0 and iTUBE, on the other hand, are more sort of luxury add-on products. In comparison to the iDAC2 and iCAN SE, they don’t bring nearly as much bang-for-your-buck to the stack – especially when you realize the iUSB3.0 and iTUBE together constitutes over half of the cost of the iStack. However, they can do some good things to your sound, and I think pairing them with some reference level products will create very positive changes for a relatively affordable price.
