en parcourant un blog que j'apprécie beaucoup http://nwavguy.blogspot.com/
J'ai découvert que suite aux critiques qu'on lui a fait, comme quoi il ne faisait que dénigrer le travail des autres, il a sorti les plans d'un amplis DIY qui semble sympathique

je suis en train de lire les plans, mais je pense me laisser doucement tenter à voir ce que ça donne.
D'après ABI, le bougre insinue que ça envoie du paté, à voir donc, je vais tenter de m'en faire un.Some design principles of the O2 are:
State of the art audio performance with most any headphone out there, from the most sensitive multi-armature IEMs to full-sized high-impedance headphones
Usage of inexpensive quality parts instead of overpriced “boutique” components
Easy to solder and assemble (no SMT components)
Precise volume control (no crackling or audible imbalance at low volume levels)
No dangerous clicks/pops at turning on/off
Usable as a portable or a desktop amp (batteries and AC power)
Switchable gain
Battery rundown protection
In the end, the price of the parts used in the O2 should come to about $30 (without enclosure, panels, or wallwart) – and according to NwAvGuy the audio performance should be indistinguishable from top quality studio gear like the $1600 Benchmark DAC1. I, for one, am very interested in building my own O2 to find out how it performs.
