The iTube 2 offers three settings, which are user switchable and offer different sonic characteristics, each of which unique to different types of Tube Amplifiers. The settings being:
-Single-Ended Triode power amplifier;
-Push-Pull tube power amplifier;
-Classic Tube amplifier;
There is no "right" setting, you choose the one you like or the one that sounds the best with your system.
Even though XBass+ for Speakers shares the same philosophy with the XBass+ for Headphones technology, but other than that, both are quite different in how they work.
XBass+ for Speakers gives every audio system an adjustable level of bass control to enhance the listening experience through speakers that have limited low-end extension.
Drawn from the ground breaking work of Alan Blumlein, the "Father of Stereo", the 3D Holographic+ technology from iFi adds another level of performance to high-end speaker systems.
First, it corrects the spatial distortions in recordings. Second, it widens the soundstage beyond that of the speaker placement. It has three modes, being:
1)Off - 3D+ being inactive.
2)"+" Mode - It recreates the Original width of the recording. Recommended Default.
3)"30˚+" Mode - Adds an extra 30˚ of stage to redress the narrow placement of speakers.
The iTube 2 PCB features Direct Coupling, which means no separate out coupling capacitor, for the purest, direct signal path. It's something that has trickled down from the Big Daddy Flagship, the Pro iCAN.
The iTube 2 uses high quality capacitors made by TDK and Panasonic, designed explicitly for audio use with extremely low distortion (<0.00001% @ 1v/10kHz).
It also uses ELNA SIlmic capacitors, found in audio components with prices with an additional 0 in front of them.
