Probably me being daft, but I’ll ask anyway, as this has been bothering me for months!
I’m running a Nova now, previously had an Atom until January this year.
I’ve noticed when streaming (mainly Qobuz, but experimented briefly with Tidal - not as good IMHO), most albums need the volume to be around 22-25, although some ‘quieter’ variants see it at around 28/29, never had it any higher than that.
However, even at 25, I look on the app track volume, and 25 appears to be at less than 1/4, which I assumed 25 to be.
I just find it odd to go any more than that! I picture other hi-fi gear from beforehand, and for where I’ve always positioned units, 1/4 was always plenty to fill the room. Although 30+ on the volume looks less when on the app!
