While we joke that the Exogal Comet DAC knows math better than you, it’s not exactly a joke.
In simplest terms, the Exogal Comet follows the sound wave more closely than any other DAC we know exists.
It does it without interpretative filters that can ’smear’ and create ‘clinical’ sounding playback.
While DACs have come a long way others still interpret the sound wave and rely on filters and loss to fill in the missing bits.
That’s where the trouble begins.
Exogal doesn’t use any filters to ‘clean off’ the signal or ‘upsample’ or interpret the sampling. Exogal uses pure math or in this case Calculus to do the wave forming. The Comet adheres as closely as possible to the original signal. The result is groundbreaking for digital. You simply do have to hear it to believe it.

Too simplistic, here’s a little deeper dive….
Does this mean the Comet doesn’t use a DAC chip? Well, there is a DAC chip in the Comet, but all its used for is assigning input and output. No computational work. Once the pure digital wave hits the chip it merely converts the signal to analog. Then assigns it to an output per your instructions.
The Comet doesn’t use any filters? Actually, like the previous, the answer is yes, none. However, physically there is a filter in the Comet - but this is only used for computational purposes and phase correction. It’s not used as a filter. So in essence there is none.
Is the Comet capable of playing back MQA? No. After 2 years of playing around with MQA it didn’t achieve the promise. The way the Comet works is still superior in our minds.
Oddly, lowly formats like MP3’s actually sound much much better going through the Comet. This has been proven over and over at audio shows. Naturally, FLAC and higher rez files (DSD, etc) sound remarkably better. (This is the part where you say, “I have to hear it for myself” and we are open to sending you one).
Most DACs create a sawtooth waveform instead of a smooth waveform (Comet) adhering to the original sound wave. Once you have the sawtooth waveform you need ‘clean off’ filters. They interpret the missing sampling and sand off the edges. Removing even more sampling. Even MQA will not fix that.
Only an inventive approach like Exogal is going to create a the product that makes you want to listen.
How about ladder DACs or NOS DACs? These are optimized to Redbook frequencies. Not Hi-Rez files.
Again, the most simplistic terms, the Comet uses minimal parts to create the maximum playback. Just like any pure, superb audio component.

So the ION PowerDAC is an amp, right?
No. It’s as revolutionary as the Comet. It has no gain. It’s a variable power supply that can switch from the lows to highs within fractions of a second.
This gives it a transient response of 100,000 Hz which means that rapid changes in volume occur with less "lag" due to gain stage delays and feedback loop delays. Which means the Ion can create the sound signals faster as they occur in the recording.
The ION also monitors your speaker giving it the power it needs when it needs it. By doing this ‘ringing’ and ‘overshoot’ damping the signal digitally when needed so you get more of a ‘live’ sound. Instant to instant, note to note. Every ‘bit’ of bandwidth.
