The Hugo M Scaler brings the unrivalled advantages of our ground-breaking FPGA-based WTA (Watts Transient Alignment) filtering technology to digitally connected audio devices, dramatically improving sound quality. Although optimised for use with selected Chord Electronics DACs (for the maximum 768kHz upscaling/decoding benefit), the Hugo M Scaler can be used with other DACs with suitable inputs, subject to their decoding capability.
The purpose of showing impulse response is to visualize filter characteristics therefore whether it is legal or not is irrelevant. However people need to pay a price for a super steep filter since it will generate higher intersample peaks.A slight aside, thinking out loud so dont throw rocks. Isnt a single sample impulse by definition an illegal signal? Should we not only ever test with a signal less than 1/2 sample rate?

Also, illegal signals in music can be an art form.
