Smartphones tube amplifiersDigital devices are not something a true audiophile would consider as a great, or even good, audio source. Considering how poorly encoding can be that's true, but there are amplifiers that can rise the digital audio to a higher level.


Now, to compare amplifiers for smartphones, tablets, and MP3 players with high-end audio equipment is simply impossible. First, music comes to those devices from a range of sources and you never know how it is encoded and there is no device that can convert a poorly made digital file into a beautiful audio event. Second, we had a hard time searching for decent amplifiers with tubes (noname devices we won't even mention). However, we have found a few interesting devices that can make bring your digital sound a step closer to real Hi-Fi.
