power supply

Since my girlfriend is getting increasingly frustrated with how user unfriendly the MRX1120 is, and the fact that we still need a separate WiiM streamer is also becoming annoying, I’m looking for an AVR with better HDMI board features for my 5.1 system. It is a long story, but due to awkward...

(TL;DR Does the proliferation of power bricks used by the new generation of small Chinese boxes cause more of a problem as far as dealing with the rat's nest of wires hidden on the floor or at the back of the equipment shelf?) I'm planning to move from my legacy 1970s-1990s traditional large...

Hello. I am currently having some issues with my DAC, an iFi Zen DAC 3, while it is being powered by USB. I am hearing some audible noise/clicks when I change the gain/volume via the units knob. I am hoping to solve this with an external power adapter, and eliminating the power via USB to the...

Long-time listener, first-time caller... Been looking at some of the recent class-D wonder-amps (fosi, aiyima, smsl, topping, etc) and noticed that the 2 main "tweeks" are 1.) roll the op-amps and 2.) get the 48V power supply. I thought the power supply advice seemed logical and was pretty...

I use a USB bus-powered ADC / DAC: Should it perform differently if connected to a typical switching PSU-powered computer, vs. a battery-powered laptop? The unit is a KORG DS-DAC-10R for digitizing records (or specific masters) not already [easily] available in 1’s and 0’s. I know - the KORG...

Hello hello! I was at the Montreal Audiofest this weekend and we came across a room where they were showing a ''power management system'' https://dracoustics.com/en/produit/antigone-power-management-system/ basically, this thing is all about reducing noise on the power in of the amplifier (as...

Since there seem to be no or few polls relevant to this topic here, and since I'm more confused now than I was before I had spent many hours/days checking out threads here: Which DAC/amp combos (edit: I prefer to use a combined and and DAC) are generally agreed upon as being best, under maximum...

I'm looking put together a 4 channel TPA325x based amplifier for my car. Preferably a TPA3255 based solution. My only requirement is to have 4 channels. Basically I as I understand there are 3 methods to approach this..... 1) Get a dedicated 4 channel board with 2 TPA3255 chips inside. Like...
