iFi Audio – micro iTube2 Mini Tube Preamplifier
The micro iTube2 is a tube output stage, preamp, buffer, and impedance matching device, all rolled into one. If that sounds a bit technical, it means injecting a tube character into your stereo sound and it will work well with whatever device you choose to connect.
The magic of tubes
The micro iTube2 is a tube preamplifier stage, 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.
iFi gives you options 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 about what you prefer in the moment.
And the choices continue. iFi adds its sonic fining-tuning nuances to your listening.
- xBass+® cleans and restores the bass to give you a richer, deeper sound,
- 3D+® opens up your music to bring a live-concert atmosphere into your living room.
Hear the difference
The iTube2 delivers that special tube sound – it adds warmth, removes hardness, and emphasis to instruments and vocals.
Give it a whirl in your set-up. Hear the Tube difference.
DirectDrive® equals a direct signal path which means less signal degradation. This direct signal path is unequaled in audio and is the reason why the sound is so ‘true’. Dig deeper here.

POWER OF CHANGE – IFI ITUBE2 // IPOWER // DC IPURIFIER 2 – REVIEW
iFi iTube2 is a Tube PRE-AMP designed for large home systems, while iPower is a power converter that comes in handy if your source doesn’t come with a quality power brick, or if you need a replacement power brick.
There will also be a bonus product features in this review, the DC iPurifier 2. Since I have no comparisons for any of those products, I’ll try comparing them with other options out there throughout the review, but there will be no special comparison section within the review…
Will enhance your sound stage experience on any gear. you will be amazed! Give 2 weeks break-in period before any critical listening and playing with settings. Instruments had their own space, rock solid images. Get up and walk around them. Of course for that effect your gear probably needs good synergy!
Tiny audio hardware that produces great sound…
1st time to use this brand. Bought without auditioning, after reading so many rave reviews.
Sound was very good, soundstage expands sideways and sound stage deepens considerably. I was also using a new power amplifier so I cannot ascertain if the great sound was due to the latter or a combination of both.
Was surprised that this unit was that tiny…but it runs fairly warm, not sure if I need to raise it above the table high enough to facilitate heat dissipation.
One odd phenomenon:
This unit produces no sound if I turn it on 1st, before I turn on the power amplifier, DAC etc…
Now I turn on everything first, before turning on this unit. When the vacuum tube is ready (need to wait about a minute), when the tiny hole that shows red turns to yellow, then sound will come out of the speakers.
Not sure if other users have the same issue or not.
Easy A/B comparison of unaltered signal vs “tubified” sound
Pros – Simple setup, Easy A/B comparison of unaltered signal vs “tubified” sound. Ability to customize audio parameters to suit your current headphones from most any source, rather than constantly swapping headphones during your listening sessions.
Cons – While still quite portable, not battery powered like the iDSD & iDSD Black Micros for TRUE portability during travel.
iTube2 smooths out digital sound for better listening
Using this as a tube buffer stage and it works great by adding a nice smooth analog sound to digital. I recommend it for anyone who wants ‘tube’ sound on a budget.
