Two years ago, boutique manufacturer MST rocked headfi by teaming up with iBasso to create what was arguably the highest quality portable amplifier on the market. Getting one required some patience as MST are a small outfit with a few employees. Their FiQuest, which has been upgraded in the year 2012, is better than ever. In this review, TouchMyApps will be looking at two versions, plus a small optical DAC.
If you aren’t ready to take the wild walk on the DIY side, but still want to really get down and dirty with tweakable headphone amps, there are a very few options available to you. One of them is to experiment McGuyver style with cotton, fish, cookies, and an oiled grouse to achieve a truly experimental sound. But if lock picking DIY isn’t your thing, there are only a few choices on the market. Some such as Graham Slee, Firestone, iBasso, etc., offer headphone amps with user-replaceable op-amps and slightly modifiable circuits, but no one outdoes MST, a one-man operation out of Akihabara Japan. MST’ FiQuest project is as ground-up tweakable a design as is possible in a pre-fabbed design. In a way, it is the audio evangelist among portable amps.
Feel free to discuss the FiQuest in our forums.
