iFi Micro iTube2 Analogue Tube Buffer/PreAmp. An Inexpensive Must.
Now at True Audiophile
These little tube buffers are doing things within system that just amaze everyone who uses them. The parts selection alone is unbelievable. We heard so much about this line from respected dealers and audiophiles we had to hear them to believe it. Yup, the buzz is right. This is incredible Audiophile grade gear on a tight budget. Secret is they've been designed by a group of engineers who normally work on gear well over $5,000.00 and wanted to give back to music lovers who have more ears than money. Loaded with brilliant tech and careful parts selection. Can't go wrong.
After weeks of testing the results are just like below. Astonishing for what it does for a system at it's price. It gets a BEST in CLASS award -- TA
iTube2 – “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!” - HeadFi/Showcase

iTube 2 : ” Clear winner….
“It gave a nice concert hall sound…I had this going for probably five/six hours straight with no problem whatsoever…I really like this portable fairly affordable iTube2…” --HeadFi
“….the iTube2 will have to be pried out of my cold, dead hands before you will get it out of my system.”
“…I absolutely freaking love the iTube2…you should try out the iTube2….the iTube2 will help out with the vast majority of systems…the closer you can use tube equipment to your source, the more impact it has….It connects with regular old analog RCA connectors. The iTube2 adds the tonal richness…. You keep the goodness of your existing equipment while fixing the core problem that modern recordings represent….Putting the iTube2 into your system gets you 95% of the improvement possible. Using the switches lets you dial in that last 5%….The iTube2 loses no resolution and still gives you the magic of tubes…It makes your system more true to real life.” -- A iFi iTube2 review by Tyson on Audiocircle.
The original iTube became the ‘go to’ tube buffer for any and every home audio system. We have redesigned the micro iTube2 with new parts and new circuitry using trickle-down technology from the flagship ‘Pro’ series. Only the GE5670 tube remains.
The micro iTube2 is a tubed output stage, tube preamp, tube buffer AND an impedance-matching device all in one. There is nothing like it. You can put the micro iTube2 before a solid-state preamp and another one after it, creating the effect of tubing the whole audio chain. Or you can choose to simply use the micro iTube2 as a very high-quality preamp by itself.
The micro iTube2 sounds by and far, like a tube amplifier ‘done right with the inimitable magic of tubes.‘ Tonality and heft, especially in the mid-range and bass frequencies are increased to elevate the whole audio system from $100k to $1k. The micro iTube2 injects a serious does of tube magic into any audio system.
|‘Magic’ of SET, Push-Pull or Classic Tube sound|
|In the ‘magic of tubes’ listening stakes, the iTube2 offers the listener the choice of different key sonic signatures:
XBass+® matrix for Speakers, new and improvedXBass+® for Speakers is quite different to its sister technology XBass+® for Headphones. The only similarity is in philosophy as the ability to enhance your Speaker listening is quite different to enhancing Headphone listening.
The former gives each and every audio system adjustable levels of bass control to enhance listening enjoyment through speakers that have limited bass extension. We have taken great care to ensure no degradation in sound quality occurs.
|20 Hz (6dB):||For speakers missing only the lowest bass notes (below 40Hz).|
|20 Hz (12dB):||For speakers missing some bass notes (below 80Hz).|
|OFF:||XBass+ switched out.|
3D Holographic+® matrix for SpeakersThe latest 3D Holographic+ matrix for Speakers offers something quite special. It takes high-end systems to another level of performance. It was drawn from the original ground-breaking work of Alan Blumlein, the ‘father of stereo.’
Firstly, it corrects the fundamental spatial distortion in recordings. And secondly, it increases the width of the soundstage beyond that of the speaker placement.
|30˚+||This matrix adds an extra 30˚ to redress the narrow placement of speakers (eg either side of a PC monitor).|
|+||This matrix recreates original ‘width’ of the soundstage and is the recommended DEFAULT setting.|
|Off||3D+ switched out.|
Brand-new PCB, Direct-Coupled for purest signal pathThe iTube2, in-line with the latest iFi products, is ‘Direct-Coupled.’ This means no output coupling capacitor for the purest, most direct signal path. Furthermore, the iTube2 is virtually a whole new product as the circuitry and components have been radically changed and it now is more closely connected to the Pro iCAN. Trickle-down from flagship range? A definite “yes!”
Reference class parts qualityThe iTube2 employs Japan TDK C0G type capacitors. These are complimented by Japan Panasonic ECPU Film Capacitors explicitly designed for audio use with extremely low distortion (<0.00001% @ 1V/10kHz).
The iTube 2 also uses ELNA SIlmic capacitors. These and other parts are only found in components with an extra ‘0’ to the price.
The proof is in the listening. The best tube buffer/pre-amp out there just pulled even further ahead. Running silently in the background – iPower 15v Every iTube2 comes with the very-new iPOWER (15v) which is a remarkable-quiet, advanced DC power supply that features: Active Noise Cancellation+® drawn from military radar technology 12-Element Output Array/6-Element Input ArrayMeasured on the Audio Precision 2, the iPower has an astonishingly low audio band noise floor of just 1uV while it has the ability to power the iTube2 to put out a maximum 7.75v which is quite remarkable.
