HiFimeDIY T3s - a 600 Watt Audiophile Grade Amplifier
This is the flagship amplifier currently from HiFimeDIY. You really can't go wrong with this. Buy the amp, the power supply, and the case (links below), and get the components from here and bam! You've got an amplifier that easy to assemble, costing less than $200 which will blow away amps costing ten times more.
This is the highest powered amp from HiFimeDIY, with the ability to put out 300W x 2 channels for 4Ohm speakers. Also accepts up to 8Ohm speakers.
These sound superb through my Wharfedale Diamond 121 bookshelf speakers. A very neutral and natural sound, with mellow but crisp highs and tight, refined bass.
