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!
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.
Sonic-tuning
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.
Only the best tube for our products. The GE5670 made by General Electric. Nothing comes close for quality.
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’.

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…

Must Have
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.

Buffer
A buffer amplifier (sometimes simply called a buffer) is one that provides electrical impedance transformation from one circuit to another, with the aim of preventing the signal source from being affected by whatever currents (or voltages, for a current buffer) that the load may be produced with.
Impedance matching
Impedance represents the opposition that an electronic component offers to an alternating and/or direct electric current.
Impedance matching is when a device ensures that the maximum power transfer from an amplifier, for example, matches the impedance of the source.
SET / Push-Pull / Tubes
A single-ended triode (SET) is a vacuum tube electronic amplifier that uses a single triode to produce an output. This doesn’t ‘split’ the music signal and the music’s ‘pure’ nature remains intact.
A push-pull amplifier uses a pair or more of tubes/devices to generate an output. This splits the signal and then puts it together again. Some argue that the signal is not put back together with the exact purity it had to begin with.
Some feel that tube amps which deliver a classic tube sound create a warmer, more musical tone.
