@audioman58 Is not wrong. For speakers the driver to speaker cost is at least 10:1, a major reason why some turn to in-house drivers. It's not just engineering but cost. I've seen some brands like Rega pump up the ratio of the electronics even higher, say 20 or 30 to 1. I'm thinking of a headphone amp I took apart once. Ugh. |
This linear power supply has got some traction on The Audio Standard

Fidelizer Audio just released their Aura for $219. Considerably less than their Nikola LPS. |
Only Teddy Pardo and SBooster list the most important specification: ripple noise/voltage. Teddy Pardo regulates it down to an impressive 1 µV. However, the SBooster ECO has a relatively high ripple of <1 mV at full load. It is recommended to purchase the Ultra add-on, which reduces ripple to the 10 µV range. Alternatively, consider the LHY PS, which offers 17 µV ripple at no load and 150 µV at full load for around $60–70 (15VA model)—not bad at all. |
Save some extra pennies and get a Keces P6 for $550. Two separate outputs, both variable from 5V to 12 to 24 and every output in between, i.e., a more versatile high quality unit (you may always need additional LPS outputs in audiophilia) https://power-holdings-inc.com/Keces-P6-6-Amp-Linear-Power-Supply-p485459710 |
