Clearly, the design faults of the Mytek are not just about linear vs. switching, but several other compounding issues.
It’s been demonstrated that linear power supplies are not uniformly better than switching power supplies in audio applications. The Benchmark AHB2 is one of the most notable examples. Linears are superior in some applications, but the design engineer has to decide what tradeoffs to make.
I love what Michael Fidler has written about his use of linear power supplies in his phono preamps, both unregulated and regulated. Ron Sutherland points to a different set of tradeoffs in his SMPS-powered preamps.
Sometimes is about the visuals too if you mess with this stuff (apart that is far easier),the total lack of harmonics in a nice linear makes nice charts.
Here a silly one of my 15-0-15.It's not even made with 78/7915 but with double 7815 from the drawer,the old DIY hack.
It's on one of the x-overs I have to play with,so a 80Hz is more suitable for detecting as with 1Khz everything lower than 250Hz (the filter freq) would be greatly suppressed.
Nice and clean all the way,simple and will probably outlast me.
The fact that the filter is on (there's no other way,it's analog) adds extra points as filters can mess up things big time.
Edit:Here's one I took good care off,sadly it maxes my old interface's ability to measure it,I need a Cosmos ASAP:
Seems to me there are lots of benefits to using actif analog crossovers over DSP crossovers, if you are using a Dac to convert to analog then using a dsp, are you not converting back to digital? Can't be good. If you are using an actif analog crossover you don't need a 8 chanel Dac. Also with a...
