iFi micro iCAN SE: The new SE model delivers up to 4watts of power into 16 ohm (this usually = about 2W at 32 ohm) which will prove plenty to cleanly drive any headphone with ease. There are three gain settings on the bottom plate, of 0, 12 and 24 dB, with large gain differences between each, meaning you can use the iCAN SE with a huge range of cans. It is still a small size taking up little desktop space, has rca and 3.5mm inputs, a 1/4" jack and iFi's 3D and XBass modes to enhance listening with some headphones.
If you want a clean, powerful amp in a small footprint, this is a great, affordable amp.
Output impedance is 0.1 ohm, so it will not alter the response of any headphones or earphones.
From iFi: The iCAN – Special Edition is a ‘specially-tuned’ version of the top-selling micro iCAN. Sonically, it boasts Class A, DirectDrive® and TubeState®. Features wise, it features a newly-refined XBass®, 3D Holographic® for headphones and 0dB, 12dB and 24dB Gain adjustment. Powered by the all-new iPower (15V), the special Turbo headamp® circuit pumps out 4,000mW to drive even the most demanding of headphones.
The TubeState creates a warm, spacious and natural sound, without the noise and distortion most tube circuits produce. This TubeState® circuit is exclusive to iFi, and it dishes out quite a large dollop of sonic improvement, over and above other mains powered Class A headphone amplifiers.
