Hey...we're on a roll!! The Lyngdorf Audio TDAI-2170 integrated amplifier with built in "Room Perfect" room calibration wins the 2017 Absolute Sound Editor's Choice Award...that's twice in a row but who's counting. This technological marvel will make your system sound better than ever in any room, with the furniture anywhere you want, in about 15 minutes. Yes, the matching Lyngdorf MH-2 speakers and BW-2 boundary woofer are a perfect match but any speaker will perform dramatically better...every time. The optional USB or 4K video card makes it easy to connect to your computer or UHDTV and because its pure digital, there's no need for a DAC. Congratulations to Lyngdorf Audio on the remarkable TDAI-2170...technology really does have a purpose!!
