The DS225 stereo power amplifier is a model in the “Definition Series” from Audio Research. Designed entirely in-house by the Audio Research engineering staff and every amplifier is entirely hand-made from the ground up in their Minnesota facility where it is tested, burned-in, and evaluated in a reference system before being shipped to its new home. 2 x 225W / 8ohm and 2 x 360W / 4ohm, meaning the DS-225 can also control tough-to-drive loudspeaker systems.

This DS-225 has been supplied by the former official Dutch distributor. Newprice: 6.490 euro (pricelist is available), now for 1.750 euro.
