Which models do speaker and room correction?

All models do. The HDP models also provide HD-Active™ – the ability to do linear phase digital crossovers.

Which models are Roon Ready?

The PreMate Plus and the HDP-5 are Roon Ready. The touchscreen displays the artwork for the current album playing.

Which models do HD-Active?

The HDP-Express II, HDP-4 and HDP-5. The HDP-4 and HDP-5 offer balanced and digital outputs. The HDP-5 offers a touchscreen control panel and network audio including Roon.

Is there any downside to getting an HD-Active model if I plan to use only stereo speakers to start with?

No, there is no downside (apart from the difference in cost). The HDP-4 is just like the PreMATE but with HD-Active capability; similarly, the HDP-5 is just like the PreMATE+ but with HD-Active capability.

How long does it take to receive a DEQX after ordering?

It depends on whether we have stock of your ordered model and configuration (e.g. faceplate color) on hand. Typically, units leave the factory between 2 and 7 business days after ordering. Every unit is individually tested prior to despatch.

Where can I hear one for myself?

We regularly attend and exhibit at audio shows, including the Rocky Mountain Audio Fest. Many of our dealers have a DEQX set up for audition, and you may be able to use our home audition program.
