Hi all the comments are great. I am replacing the opticable for coax. The biggest thing I hear is some times the music does just no sound life like enough. I was concerend it was my hi res player or not enough watts in to the 4ohm speakers. But it sounds like my best options would be a dac, new speakers, or just upgrade amp to stero one. The idea of a dac sounds wonderful too. The athem does have dac internal. It's a AKM 4458 DAC 32bit 758. So would a dac still help. I do apologize if my post causes a well why did you not tell us that moment. I go to a lot of symphonies and I love violins. Some times when I playAdagio for Strings Op 11. The high frequency parts sound harsh instead of clear and buetiful.
Improve sound
I have a pair of martin logan 40i. Blusound node most recent version. Anthem mrx 720. I have the speakers connected with bi wire blue jeans speaker cable. The blu sound via optical cable. I have about 1000 dollars. What could I upgrade. Thought about getting an amp like the parasound 23+ or upgrading the streamer to a cambridge. Please I would love some help/suggestions.
Tim.
