Summary...."The all-one-one aspect of the Lyngdorf TDAI-3400 showed its value in how it obsolete nearly $70,000 in gear in my room. Integration with Roon player (i.e. streaming) does it for me. Get yourself a pair of excellent speakers and pair it with the Lyngdorf and "you are done." Your tiny system will outperform tons of other systems without equalization."
