micro iTube2

Still feel there’s something missing from your music? Playlist a little lack-lustre?

Try the iTube2 – bring the warmth of ‘tubes’ into your home.

The magic of tubes

The micro iTube2 is a tubed output stage, preamp, buffer and impedance matching device, all rolled into one.

Put simply, whether you are listening to vinyl, CD or a digital stream, it will add depth, bass and personality to your playlist.

Spoilt for choice.

At iFi, we love giving you options and the iTube2 is no exception.

With the iTube2, you have a choice of three key sonic signatures:

  • Single-Ended Triode
  • Push-Pull Tube
  • Classic Tube

There is no right or wrong. It’s all down to what you prefer.


And the choices continue. We’ve add our own exclusive optional ‘sonic fining-tuning extras to add further nuances to your listening.

xBass+® cleans and restores the bass to give you a richer, deeper sound and 3D+® opens up your music to bring a live-concert atmosphere into your living room.

Hear the difference

Why did we give you a tube amp? You know how much we love them here at iFi and we know some of you do, too.

We feel the iTube2 delivers that special tube sound – it adds warmth, removes hardness and adds emphasis to instruments and vocals.

Give it a whirl in your set-up. Hear the difference.

Choose the ‘magic’ of SET, Push-Pull or Classic Tube sound – three different sonic signatures. There is no right or wrong, it’s whatever you prefer!


Only the best tube for our products. The GE5670 made by General Electric. Nothing comes close for quality.

3D+ Holographic® delivers an immersive, deep soundstage. Check it out here.

XBass+® delivers a deep, tighter bass sound. Discover the details.


DirectDrive® equals a direct signal path which means less signal degradation. This direct signal path is unequalled in audio and is the reason why the sound is so ‘true’.
