DAC Cost No Object Winner
Ideon Audio IΩN+
For those who can’t quite reach to Ideon Audio’s range-topping Absolute levels, there’s IΩN. The IΩN DAC (with optional preamp, which is known as the ‘IΩN+’) shares much with the Absolute model at a considerably more attainable level. Like its bigger brother, the IΩN DAC uses an ESS chip (the ES9028A PRO converter chip in this case), with dedicated software written in-house at its Athens design studio. Another ESS chip from the PRO family is used for the USB audio input module, which is again subject to a lot of in-house custom coding. Both Ideon DACs process PCM signals up to 32 bit/384 kHz, plus DSD64 to DSD512 natively. It has galvanically isolated USB Type B, and coaxial S/PDIF via BNC or RCA inputs and outputs to XLR and RCA. The IΩN+ adds two analogue inputs (XLR and RCA), with one stereo set of XLR and RCA outputs.
A happy terrier
“The IΩN grabs hold of your speaker cones like a happy terrier,” said Alan Sircom in our test, “and won’t let go of them until it’s satisfied with a spot of Rammstein or Infected Mushroom. That stupid smile breaks out across your face at that moment as you realise just how much precision the Ideon Audio is putting into that bass, and just how rewarding that sounds.” He added that this depth also “underpins the music in a way that gives instant solidity and authority.”
He signed off the review by saying, “If you set aside the sleek advertising and fancy front panels of some of the better-known big hitters and instead concentrate on what sounds fantastic, the Ideon Audio IΩN DAC is the one to beat.”
