A linear power supply (15 volts 4 amps) from Ali Express for US$95.00 used with a Lindemann Limetree bridge made a worthwhile difference. The mid-range was noticeably better and less constrained. Some female voices were slightly shrill
Lindemann mention that their plug-in PSU is a "hospital grade" unit. Maybe so, but it is still a switched mode PSU
I had earlier replaced the 19 volt 3 amp PSU with a ASUS gigabit router. Our fibre services was upgraded from 100 mbps to 200 mbps. It made no difference to the sound quality from Tidal but the PSU was quieter. Not much but if you put the original one back, it was perhaps grainier. Likewise I built a 5 volt PSU for the switch using an L7809CV linear voltage regulator since the switch only needs 2 watts
