Kosst,
Use of a massive bank of capacitors does sound very interesting. Have you tried this approach yourself? Also, are they suited for constant drain (I thought they were primarily used where fairly rapid cycling is involved)?

I used a capacitance multiplier circuit on a preamp once, worked very well, bit hard to do on a poweramp though. http://electronics-diy.com/electronic_schematic.php?id=486 Cheers George |
The new Rowland Power Storage Unit (PSU) is a full chassy external ultra-capacitor-based power supply. It has been designed to power simultaneously up to three line-level devices... A Rowland Aeris DAC, a Corus linestage, and as one spare output for future use. I have had it in my system for about three months, and have applied it to my Aeris, as I am not currently using a line stage. The enhancement that PSU has brought to the system is rather phenomenal, for all audible parameters I can think of.... Its effect is tranformational: more in line with a substantive upgrade of all electronics, rather than the replacement of just one power supply. Regards, Guido |

As a cheap experiment born of curiosity, I tried using a a widely available commercial "online" uninterruptible UPS, which does a full AC>DC>AC conversion for all power output, here: https://www.amazon.com/dp/B0050NZTQ2/ref=cm_sw_r_sms_tai_GYJ4zb8PJA3P1. In other words, it is NOT a stand-by power source; it is the primary source. It has a rated output of 1500 amps, far in excess of my system's needs. According to the included monitoring software, output, voltage and frquency were rock steady regardless of the music. The results were impressive, even though the nominal THD quoted for the UPS was poor. Using a sound meter, hiss and noise at the speakers dropped 4-5 dB. Music sounded both more detailed and with greater air. Bass seems unchanged, but admittedly I am not a bass fiend. Ymmv. Cheers, Alex |
