Astron & older LPS’s
My rig’s SQ for streaming Tidal was boosted substantially when my Astron 11A was replaced with this newer ultra-low noise LPS for powering my modem/router. The body/weight of the music became rock solid – I mean rock solid. The noise floor dropped significantly more - and my system was already extremely quiet. It appears that the modem/router needed a faster-acting delivery than the Astron could provide.
I was intrigued that this particular unit used an R-core transformer with bi-polar transistors to regulate the voltage. Even though the modem and router draw only 1 amp each, I wanted to provide an extra beefy power supply to see what would happen. I’m glad that I did. It was worth the extra $20. I have since purchased a 2nd one for my Empirical Audio Off-Ramp 5. I replaced the cheap 12v umbilical cord with high quality OCC copper wire – and installed a SR Black fuse. The circuit that the modem/router were on, already had a power conditioner - fed by a good quality power cord. A nice by-product is that my web-surfing is much faster, too.
This company has a smorgasboard of LPS’s with a variety of circuit designs. I can definitely vouch for the version that I got. Each unit arrived in the U.S. within one week of the order via DHL. The units are built like a tank. Top-notch in every respect - parts, assembly, functionality and cosmetics. No, I’m not affiliated with this company at all. Just a happy customer.
