2 BILLION farads...? Does that even make sense? I cannot imagine the need/benefit. Grannyring, can you help me understand the significance of this seemingly over-the-top specification from a functional point of view. I'd think you'd need a chassis the size of a snooker table to mount all those caps in.

Just wanted to make audiophile community aware, anyone looking for a DAC must check out Galle DAC from Cinnamon Audio. The feedback from two recent buyers was very inspiring and they bought the DAC after listening.
"The Galle DAC: we’ve crafted a DAC that delivers a natural, lush sound with remarkable dynamics and harmonic richness"
Cutting edge R2R, 27 bit ladder, laser cut the resistors to hit 0.1% tolerance; installed directly into the circuit board for a bargain price of $12,995
You can hear this DAC at Capitol Audio, courtesy @gestalt audio.

“2 BILLION farads...?” That’s an extraordinary amount of filter capacitance for a DAC—2,000 farads. Such a massive power reserve would have a significant impact on the DAC’s ability to maintain stable performance under varying load conditions. Massive power reserves ensures ultra-clean power delivery to the critical digital and analog sections, minimizing noise and ripple while improving dynamics, transient response and overall sound quality. Typically this level of capacitance is found in high-end power amplifiers rather than DACs, making the Galle II design quite unconventional. How does this sheer overkill in capacitance translate to real-world performance…only time will tell! |
@grannyring - I am pretty sure that's 2000 MICRO farads. |
Don’t mean to nitpick, but the manual states "just short" of 2 billion micro farads. "The Model II is the answer to a persisting question: what happens as power delivery approaches perfection? The Model II physically separates the power supply, uses three custom transformers to feed three individual power channels, and employs just short of two thousand Farad of filtering capacitance. That is over two-hundred thousand times the usual values used for these voltages. While the care in implementation needs to be great, the result is a better, cleaner window into the music."
A Coda 16 has 280,000 micro farads of capacitance, and it supplies 100 amps of current-per channel. In bridged mode it provides 600 watts. Seems rather excessive for a DAC to need 7,000 times this amount, unless there is typo? But what do I know about designing hifi? (don’t answer that) |
