Hi
I believe that *most off the shelf 'regulated' supplies have the following:
1) A lower cost poor regulation transformer
2) A cheap and noisy std rectifier bridge
3) High ESR caps with insufficient filtering
4) A 78XX noisy regulator with low bandwidth and high noise
. . fine for powering your Acme alarm clock, but not really worthy of powering your audio gear.
A proper PS would include a good transformer, maybe a soft recovery bridge and decent caps
However I'm looking for PSs for 3 frugalphile systems using Tripath amps: a bedroom iPod system, the old mono family TV, and my (about to build) shed . .
Might *any regulated supplies be reasonable quality, or is that phrase 100% oxymoronic . .
I think SMPS might be 'ok', but surely(?) someone sells something better than SMPS, but not a full on proper regulated PS; “mid-fi”.
From HK/ China or elsewhere in Asia?
Thanks
