Product Information

Bring the warmth of 'tubes' into your home.

Need to add depth, bass, and personality to your audio system? The micro iTube 2 separates and emphasizes each vocal and instrument. It adds warmth, removes harshness, and kicks your speakers into action. It is a pre-amp and tube buffer with gain settings so it can be tailored to suit any home audio system. It is a tubed output stage, tube line stage preamp, tube buffer, AND an impedance matching device all in one. Digital Antidote takes the 'harsh edge' from most digital sources that 'rings' in the ear. 3D Holographic for speakers restores the 'collapsed sound field' found in many systems to recreate a live stage atmosphere. XBass+ cleans up and restores a rich, deeper bass line. Try three different key sonic signatures: Single-Ended Triode, Push-Pull Tube, and Classic Tube. Tri-brid stage offers input impedances of 1M ohm (Buffer) to 100k (Preamp) with the ability to drive professional 600 Ohm loads. High-quality General Electric GE5670 tubes add that extra warmth into the sound at any stage. With nearly every home system being solid-state, the iTube2 puts the soul back into the music.

3D Sound

The 3D Holographic Sound is for Speakers. On the 'Standard' setting with '*' simply puts the bass back where it belongs, leaving the rest untouched. The 3D Holographic Sound 'Wide' setting with '***' additionally widens the Stereo sound field, for use in situations where a very narrow speaker placement is enforced such as on a desk.

The Enclosure

The iTube2 features the iFi aluminum block. This enclosure acts as a shield against harmful electromagnetic interference (EMI/RFI) to further minimize noise. Blocking all the noise coming from a PC results in vast sound quality improvements. Non-aluminum designs offer little to no shielding from EMI/RFI.

Digital Antidote Plus

With the iTUBE’s Digital Antidote Plus, this active tube "version 3.0" is ready for all digital formats right the way up to the latest high-resolution PCM/DXD/DSD and beyond. Now you can finally relax and enjoy your digital audio for longer, thanks to this.
