Avantgarde claims that with iTron technology even an MP3 music file can sound more impressive than the best high-res playback on a conventional system(voltage drive) and this is not a small claim, but when we realize the basic differences between the current and the voltage drive, it cannot be far from the mind. In voltage drive mode, there are many elements that are placed in the signal path which affect the signal from the amp to the voice coil, such as all kinds of passive crossover filters, and then the voice coil resistance and also the process of converting voltage to current in the voice coil, Which is the worst possible place for this operation and in general that variable resistance leads to rise-time delays, jitters, less immediacy and presence, dynamic limitations, etc.
So, these serious flaws of voltage drive can play a big role in the loss of signal purity from the amp to the driver, but when we go with the current drive amplification which traces the input signal far more accurantely and those iTron amps which are directly coupled to the drivers without any added filters or resistances, naturally, the least interference and the highest purity and linearity of the signal is obtained.
So it can be assumed that the pleasure Todd gets from Spotify with iTron is much more than the pleasure that we get from Tidal or Qoboz with our voltage drive systems, which is really enviable
