This is an apartment system in Vienna Austria, so not too extreme. We listen at modest volumes, usually not more than 70 - 80 db. 100% streaming these days through the ZENmini using the Sense app (we love it). We play rock, R&B, jazz and classical via ripped CDs, Radio Paradise and Qobuz. The ZENmini is connected to both the ADI and Border Patrol units. At the moment we listen mostly through the ADI DAC and the Heresey IVs. The Arendal 1723 s speakers are power hungry (88.7 db sensitivity @ 4 ohm nominal impedance) and need the full attention of the M6si at volume. The Arendals are wonderful, very analytical speakers, but after all is said and done we prefer the Klipsch (the 1723 s are for sale...). The M6si volume setting rarely goes past the 9 o'clock position with the Klipsch. Everything is connected using Audioquest cabling, except for the speakers which are bi-wired using Oehlbach cables. Sound quality is very good. There is a DECWARE Zen Triode amplifier coming later this year (or next year) that will be the trigger to build an analog capability with vinyl (researching turntables now). Any big improvements to the sound quality of this system would come from room treatments, and since we are renting this is not in the plan. Thanks for listening!
