The tech spec.

The micro iTUBE2 rocks… Why?

Because you can listen in three key sonic signatures:

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

Want to know which sounds best?

Try it yourself. You’ll figure out the one that’s right for you.

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.

Our 3D+ Holographic® dual-analogue matrices create a more immersive, deeper soundstage that puts the artist with you in the room, not just in your headphones.

XBass+® analogue bass correction system corrects headphone/speaker bass response to deliver a deep, tight and prodigious bass.

DirectDrive® means no output coupling capacitors – this direct signal path is without peer and is the reason why the sound is so ‘true’. The sonic transparency is second to none and is there for all to hear.

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.

It brought the magic back to my music!

If I had to choose a word to best describe the overall qualities of the micro iTube2, it would be magic. The power of apparently influencing events by using mysterious forces, a quality being beautiful and delightful in a way that sees remote from daily life, exceptional skill or talent!…if one is serious about their music, the micro iTube2 is a must have and should be your next upgrade!
