@mofojo Thanks for the feedback. I have demoed the Lyngdorf and I thought the preamp section was perfect for me. I was not a fan of the amp section so we tried an expensive external amp at the demo and it was lights out great. Now this may have been because the 2170’s amp was too low powered for the Paradigm Person 5F speakers I heard or maybe because the unit had not been played for a while.
I have gone back and forth between the Anthem STR pre and the Lyngdorf preamp section of the 3400 (I want balanced output with AES48 balanced standard support). The unheard STR pre makes more sense because I would not waste money on a unused amp section. However, recently I went back to reading several reviews of the 2170 and they took me back to the demo I had 11 months ago, confirming the great things I remember hearing.
The dealer that has the Lyngdorf also has the Anthem STR integrated, so I will demo that units preamp section out to an external amp to mimic the STR pre. However, my feeling is that the Lyngdorf will win out because of likely a better DAC and the phenomenally quite nature of the unit. I will give this dealer my business for the preamp even if it is not the lowest price.
BTW - The room I will use the DSP is this one,
