Created lower lows from the amp and cleaner sound.

It does make a difference. Wakes up my Fosi BT-20A Pro from 24 volt sleepyness. Tested with Bose 151s as well as JBL 4311b monitors. This Fosi combo is fun but there is a tiny trace of noise over 3/4 volume. I am running at 1/3 volume to fill a 600 square foot workshop and it’s clean loud and warm. Test music is jazz and classic rock. DC voltage for either channel is about 2 mVolts at idle. Without a scope I can’t test clipping. I do have the 10 amp power supply on a heat sink just because. I won’t ever run it so hard as to create much heat.

Too expensive for a 48v 10a power supply. I don’t see or hear any big difference with the sound. I would recommend the 48v 5a power supply.

Bought pair to power my pair of ZA3s independently as monoblocs. Seemingly unlimited power to drive my KEF LS50 Metas with these. Must be decently efficient as they don't get very hot even after days of running. Highly recommended!

If you are buying Fosi Audio equipment that is rated for 48 volts, this is the power supply you want. I'm using two of these to power two Fosi V3 Monoblock amps. These power supplies are actually physically larger and weigh more than the components they are powering.
