We will usually have a Naim Muso playing in the vinyl store, and the KEF Blades are more often than not playing on the top floor through a Classe Delta pre/power. In the reception area where the counter is, there is a choice of what we can use - Sonos Play speakers, Denon HEOS speakers, B&W wireless speakers, Denon and Marantz mini systems, and Ruark radios. If we do play anything in this area, it is usually via the Denon HEOS amplifier with a pair of speakers using Spotify or Tidal, which the current speaker of choice is the Sonus Faber Toys. The problem is with music choice. You don't play anything you don't like, and when you've been in the industry for any serious length of time, you avoid playing anything you do like, as you get sick of hearing it and end up never listening to it in your own private time. Sometimes, the sound of silence is a welcome change though! Sometimes we will suddenly find ourselves working in silence as whatever we were listening to has finished, but we've just been too busy to notice. As has been mentioned, music choice is important - if we played some of music we like, we'd get a few people walking straight back out again!
