Infuse any speaker system with the magic of vacuum tube

Posted

Pros: Rich and euphonic tube sound with selectable soundstage and Digital Antidote Plus enhancement.

Cons: Tailor mostly for speaker. Digital Antidote Plus' effectiveness depends on system.

iTube is the latest addition to iFi Audio ‘Micro’ line of audio gears. On one hand, it inhere the same minimalistic concept as the other Micro gears; on the other hand, it is a departure from the previous all-solid-state design. If anything, it is the first in Micro gears that will appeal more toward speaker user rather than headphone user. So what exactly does an iTube do? In essence, it is a tube buffer / pre-amp, with some extra features threw in. Spec Input voltage: AC 100-240v, 50/60Hz Power consumption: under 4W Idle, 10W max Input impedance: 1M ohm Direct Tube Buffer / 100k ohm Pre Amplifier with Volume Control Output stage output impedance: less than 1...

Smooth like cappuccino

Posted

Pros: smooth , pleasurable , comfortable for long hours of relaxation

Cons: an addiction.

Having the iDSD Nano & iCAN Nano from them, i was very impressed by the iFi's performance.  Making me trust my money to them, knowing they can provide what they claim it could, and deliver them so beautifully, sonically. First thing i noticed when i held the iTUBE in my hand , i immediately noticed it was significantly lighter than the iDSD Nano and iCAN Nano , which felt pretty weird . Then i realised that the iDSD Nanoand iCAN Nano both have batteries in them, making them denser. In my opinion, the denser ones felt more premium as there's a certain quality feel to them. That aside, the iTUBE also require a 3 pin power source, making them desktop bound. I ran them as such;...

Add the "tube sound" to your setup

Posted

Pros: Add musicality and warm to your setup, The 3D HolographicSound® increase a lot the soundstage

Cons: Digital Antidote Plus' isn't much effective. Close RCA input and output connector

  I would like to thank Vincent at iFi for sending me this sample for review,   I’m a fan of IFI products. I have loved their dac and usb power supply (here is my review) so i have decided to give a chance to the lastest product from the Micro line, the IFI iTube. But first, who is IFI? Ifi is a young English company with trickle-down technology licensed from AMR (AMR is a producer of Hi  End valve components). Recently they released their new Nano line dedicated to portable listening which  includes the battery supplied iDSD, a very interesting portable DSD dac, and the iCAN Nano, a portable  headphone amplifier.       The iTube it’s...

Tube magic for all systems

Posted

Pros: Warm, smooth tubey sound in any system

Cons: none i can think of.

iFi iTube Review:   I would like to thank Vincent at iFi for sending me this sample for review, I will try to write an honest review, this unit received well over 100hrs of burn-in as it has a vacuum tube in it, which are notorious for needing long burn in times.   The iTube was tested with various headphones including the German Maestro GMP 8.35D + GMP 400 and also IEM's like the Westone UM Pro30 and Final Audio Design Piano Forte X-G.   I used the iTube in different configurations, mainly iPod Classic 160gb > Silver LOD > iTube > iCan > Headphones, but also Asus M50vm > Gemini USB > iDAC > iTube > iCan > Headphones     Tech...

Tube sound effects for soundstage and extra smoothness that you can add for any solid state amp - what's not to like?! :)

Posted

Pros: Adds smoothness to any reasonably priced system with a dedicated amp, Small, Soundstage control, dissipates heat well through the aluminium casing.

Cons: Aesthetics can clash with some neat setups. Not much else really.

 Here is the original review that I posted on my blog: http://noblehifi.blogspot.co.uk/2013/08/ifi-itube-review.html   Disclaimer: A big thank you to Ifi for loaning me the iTube for this review! After hearing the iCan I was eager to get my hands on more Ifi gear. Now I've even been lucky enough to get almost their entire catalog, as well as an exclusive. The iTube is launched today - 16th August (£275). This is a fascinating little audio gadget - a buffer stage with a pure analogue circuit that includes an active tube (GE5670). The iTube can be added to pretty much any audio chain with a dedicated amplifier (before the...
