If it sounds good, then no need to spend. I used a $30 LPS for a class D amp and it sounded great. It's possible there are better components in the expensive units but you may be looking at diminishing returns.
Radio Power Supply in HiFi Application
Hello everyone, long time forum reader first time poster. I have what might be considered a noob question by some so forgive my ignorance: what’s the difference between radio linear power supply, “lab”, and the audiophile ones? I know the audiophile ones state they’re focused on reducing noise, but wouldn’t the others have this same purpose? The reason I ask is because I picked a used marine radio LPS for $20 locally to use with the uptone Mac mini conversion kit to get me by until I can afford something better, but the sound quality upgrade has been very satisfactory considering the $200 investment, so I’m now wondering whether it’s really worth spending the extra money for an uptone or sbooster for can additional to $700 or so. Hope to hear thoughts/facts on the topic and thanks in advance,
Mat
