Hardware digital tone control?

Auto EQ, $330. Someone should test this!

Behringer DEQ2496 Ultracurve Pro DSP Review

This is a review and detailed measurements of the Behringer DEQ2496 Ultracurve "2-channel Equalizer and Mastering Processor." It was kindly loaned to me for testing from a member and has a retail cost of US $645 but I see it discounted to US $429. For those of you frustrated with my lead...

Quick measurements of Behringer Ultracurve DEQ2496

DEQ2496 is a very complex device with many features and functions. It can work in digital domain entirely, or convert between digital and analog for both, inputs and outputs. First up is digital performance. This is measured using optical input and output, so the signal never leaves digital...

Or did you mean the auto EQ specifically?

I didn’t know of this, but its features are what’s attractive.

I have one. It’s brilliant.

Shame it doesn’t fit on OP’s desk.

Does anyone know of a physical product that is placed between the source and the DAC with knobs to change the audio tone in the digital domain?

I'd like to add some coloring to my music as my DAC hasn't got any filters that make any remarkable sound difference so such a product would be ideal to play around with,

Why don't you place the tone control behind your DAC?

Why do you limit to "hardware" products?

You can do it with many "software" DSP solutions; you would feed digital stereo signal into DSP software for Fq-dependent multichannel crossover and relative gain control, and you may feed the DSP-ed multi-channels into single DAC via USB ASIO driver routing. (Of course, if you have multichannel DAC and multi-amplifier setup, you may feed the DSP-ed channels into multichannel DAC, just like in my multichannel multi-amplifier setup.)

Recently, I showed this diagram in my post here, just as a simplified example case, for software DSP-based XO/EQ/Delay/Gain controls in single-DAC single-amp stereo audio system. Of course, each of the XO-ed channels in DSP can be gain-controlled.

I believe we would be better avoiding; digital source --> DAC --> ADC --> hardware digital DSP --> DAC --> amplifier(s).

I've always felt that way, but given that it's hard to tell 8th generation digital conversions from first, maybe we shouldn't care.

Strange to see there are so few products that meet my requirements. Schiit audio has three Equalizers and none of them work in the digital domain which I find quite peculiar.

I guess that’s because the progress vector to Hi-Fi is to have a playback system that replicates the source.

Yes, I too would like suggesting it.

We may use HiFi preamp with tone control between DAC and power-amp, or we may use HiFi integrated-amp with nice tone control.

Even in multichannel multi-SP-driver multi-amplifier setup, we still can use HiFi integrated-amplifiers with excellent volume controllers for analog-level safe and accurate relative gain/tone control, just like in my setup (ref. here and here).

Of course I can do the same tone control (relative gain control) using DSP EKIO inside upstream PC, but for real-time on-the-fly fine tone control, the knob-dial volume/gain control in integrated-amps wound be "safe" and convenient, I believe.

In my post here, you may find pros of using integrated amps in multichannel multi-amplifier audio setup. __In my multi-amplifier setup, gain/volume of each of the SP high level output signals given by amps are visually monitored by 12-VU-meter Array (ref. here).
