The last 10 years have been fascinating for power supply technologies in audio and non-audio applications. Batteries and Ultra capacitors are widely used in DAC designs and GaN FETs are gaining popularity in SMPS and amplifier designs. Until recently, Ultracaps were limited to fairly low voltage ratings (<5.5V), making them impractical for anything but source-related power supplies.
However, I came across the following two New Arrivals at Mouser:
XTM-18R0626-R by PowerStor/Eaton
61F storage
18V rated
22 mOhm ESR
$137 ea
BMOD0009 P024 B02 By Maxwell/Nesscap
9F storage
24V rated
139 mOhm ESR
$213 ea
Is there any drawback to using one of these to Amp PSUs? Even if used in series, it would offer orders of magnitude more capacitance than the mF of capacitance used in PSUs.
For example,
I use Folsom’s Antipole PSU with a 16V transformer (23 VDC rectified). So the Nesscap could be drop-in, or if headroom is recommended, then two in series.
Same for my Neurochrome Power-686 which is powered by a 25V transformer (35 VDC).
Thanks!
