48V 10A PS hum

These power supplies produce a noticeable noisy transformer hum.

Improves sound and power.

Upgraded the power supply on both my ZA3 mono blocks from 32v to 48v 10amp. More volts = more power as well as clearer sound. Nice upgrade. Next up is upgrading the op amps.

Who Knew A Power Supply Could Make A Difference?

I received a pair of FOSI v3 monoblock amps about a month ago with 48v-5a power supplies. They were perfectly good, but for giggles I decided to try a pair of 48v-10a supplies from FOSI to see if they would provide an audible improvement. In short, they did in two ways. The most obvious was in the bass where the output from my Zu DWX bookshelf speakers became deeper, more full-bodied, and tighter. The other improvement was in micro and macro dynamics. A pair of these power supplies are not cheap (especially relative to the price of stock v3 monoblocks), but I believe the improvement in sound quality is worth it. Recommended.
