Jul 31, 2018 · The Fizik Infinito X1 shoes are incredibly stiff for maximum power transfer, ideal for racers and pedal thrashers that don't want to give away precious power to a flexy sole, and the highly adjustable Boa dial arrangement and fit provides great comfort. Not so impressive is the high price, but if you can afford them they are a good choice. To protect your investment, the Onkyo DP-X1 features a tough, aluminium body. With no fewer than 161 step positions, the tactile volume knob gives the most precise volume control. Just like the player's sound quality, the feel and engineering of the player puts precision first. Don't compromise on your music on the move, with the Onkyo DP-X1.
