Micro iTube2
Sprinkle the ‘magic of SET’ into any system
(http://www.audiocircle.com/image.php?id=156765) (http://www.audiocircle.com/image.php?id=156764)
Reloaded, next generation
The original iTube became the ‘go to’ tube buffer for any and every home audio system. The iTube2 with trickle-down technology from the flagship ‘Pro’ series has been redesigned with new parts and new circuitry. Only the GE5670 tube remains.
The iTube2 is a tubed output stage; tube preamp; tube buffer and an impedance-matching device. There is nothing like it. Put the iTube2 before a solid-state preamp with another iTube2 after it to create the effect of tubing the whole audio chain. Or simply use the iTube2 as a very high-quality preamp by itself.
The iTube2 sounds, by and far, like a tube amplifier ‘done right with the inimitable magic of tubes‘:
1. Tube+® circuit for SET/Push-Pull/Classic tube amplifier signature
2. 3D Holographic+® for Loudspeakers matrix system
3. XBass+® for Loudspeakers matrix system
Features/Technologies
• High-end Direct Tube Buffer/High-End Direct Pre-amplifier
• Selectable tube sound signature (SET / Push-Pull / Classic)
• All-new 3D Holographic+® for Loudspeakers matrix system
• All-new XBass+® for Loudspeakers matrix system
• Pure analogue volume control
• Ultra-low Total Harmonic Distortion (THD): <0.009% (Tube+ off)
• 0dB or 9dB selectable gain
• Reference class parts quality from ELNA Silmic to C0G capacitors
• iPower (15V) included, ‘quieter than battery’ power supply
The retail price of the micro iTube2 is US$375 (ex-tax) or Euro450/£375 (incl VAT).

Any idea how long the tube will last in the iTube 2 and when its life ends is it user replaceable?

+1 - would also like to know if AMR/iFi recommend keeping the iTube2 on all the time vs. turning it off when not in use (I'm assuming the latter). And if the tube does die/get worn, is the tube user replaceable?

Hi guys, the 5670 tube utilized in the iTube2 is a beast. It can be left on with no worries. The life of the tube is astonishing, rated at 100,000 hours or 10 years of standard music listening.
-
100,000 hours equals 11.4 years (continuous).
It appears that the iTube 2 gives up the "Digital Antidote Plus" from the micro - iTube, true?
-
I really don't understand why a product like this has only a one year warranty ( and much less on the tube .) It looks very well made and I'm not suggesting it isn't.
To me, way too many manufactures in the high end give very limited warranty coverage .

We really are very proud of our products and warranty. Customers being happy is important to us. That said we have an excellent support ticket system and we take care of our clients inside and outside of warranty. And let's face it, iFi stuff is made like a tank, inside and out.

Does it come with a remote volume control? Simply as a preamp with regards to sound quality only, is it comparable to iFi iCan Pro?

The iTube2 does not have a remote. As far as the sound quality, I think a lot of people will look at the pre-amp on the iTube 2 and think it was just an afterthought, but the performance truly is stunning for the buck. That said, the iCan PRO is on a whole different level both feature wise and sound quality wise. Think of it like going from a V8 Mustang (which is great for the $$$) to the Corvette Z06 (which can humble far more expensive sports cars).

Twice above you say "for Loudspeakers matrix system". What does that mean?
-
Could we get an answer on JLM's question on the digital antidote as far as being included/not included in the mark 2 model please?-thanks

Missed it, sorry about that.
Digital Antidote is not on iTube2.
-
Ok thanks for answering that.Wonder why no digital antidote in new version? Better technology to solve same problem- (ringing digital highs) Or royalty issues? Might opt for the first version over the new one.It would be placed from my digital source to my preamp

Underdog,
For whatever it's worth, I have both the original iTube and the iTube 2 on hand. If I were in your shoes, I wouldn't get wrapped up in sundry denotations like 'Digital Antidotes'. The real litmus test boils down to how the iTube 2 performs in a real-world system. On my desktop rig (which is fronted by an iMac), I can genuinely say that as solid of a performer as the original iTube is, it's replacement is significantly better. In every way.
-
I realize that the iTube2 was made mostly for desktop applications and I understand this is where the market is going. But for me I would be using it in a 2 channel living room system and all I need or want would be a tube buffer with selectable tube signature. I would buy one of those in a minute.
Any chance of something like this ?

I am using the Itube 2 in a 2 chanel system as a preamp. Get on the tour. The 2 easily beats my Cryo Itube 1 with the Astron power supply.

What you just decribed is EXACTLY what the iTube 2 is. It allows you to select between standard mode, push pull mode and SET mode. It's super clean yet warm and sonically wonderful. Last chance to join the tour is coming up. I will have to shut the doors earlier than expected it appears. Lots of interest right now. :thumb:
-
I'm in Canada so don't think I qualify for the tour. I eagerly look for ward to the reviews of others.

Care to expound just a bit on this Tom?

I will in my review Tommy, this is much better from top to bottom. Are you on the tour yet?

Cool. Not on the tour but it doesn't surprise me that you like it better. I've been using a sainsmart preamp that has the 5670 tubes as a buffer and it's better than the original itube with Astron ps I have. The sainsmart doesn't have the ability to lower gain like the itube2 does so I'm intrigued.

Can the iTube 2 be used with an integrated amp with a separate DAC and a iMac? Thanks!

I used the iTube2 on a cheap Sony Bluray player's audio outputs and it made a HUGE sonic improvement.

I will try it out in different scenarios with my AV receiver.

It would greatly depend on the DACs output type. But just to clarify, the iTube2 utilizes stereo RCA for analog inputs and outputs. There is no other means of plugging anything else in. Hope this helps!

Pez, could you explain what the buffer circuit actually does? I've always equated buffering to allowing a better impedance match between output and input, and have thought of it as passive. Is that right? If it is passive how can the iTube 2 offer 9 dB of gain?
According to the user's manual the input impedance is 1,000,000 ohms for the buffer and 100,000 ohms for the preamp. What is the recommended ratio of output to input impedance?
Output stage impedance is stated as < 1 ohm and corrected output impedance as <150 ohms. What is a "corrected" impedance?
Thanks In Advance
