"This unit is absolutely the best audio tool that I have ever used!""…what I have learned to do with the unit as far as measurments go with loudspeaker correction is astounding! I cannot believe what I am hearing.After all these years of buying audio equipment, it has taken the DEQX to fufill my desire of audio playback. I cannot belive all the information that I had been missing. This unit is absolutely the best audio tool that I have ever used!The nice thing is that with the VRS system, all I have to do is download the software and I have everything right there. I am a believer in what this unit can accomplish and I cannot ever go back! Why would anyone in there right mind ever listen to a speaker without this tool.Thank you so much for caring about the music."Vincent Sanders, Owner, VRS Audio Systems "DEQX delivers it all. Bravo DEQX.""DEQX is without a doubt the best money spent on stereo equipment I have experienced, and I have been at it for years. DEQX is positively spectacular. Before DEQX my system was pretty refined, but the 'rightness', the 'correctness' and coherency of the sound through DEQX is amazing.The sound is significantly better—more correct, balanced, detailed, and live sounding. I dug out a 25-year-old pair of Heil Air Motion Transformers from my garage. WOW. Heils had always sounded like they had potential but had some obvious warts*. With DEQX, the warts vanished and were replaced with highly musical detail, depth, and cohesiveness.I found myself listening to every CD I had, hearing more of the music than I have heard before, and enjoying it more than I have for years. I just kept listening, and listening, and I found myself enjoying so much of the details and space around voices and instrument. The more music I listened to, the more impressed I was. The DEQX really works.This amazing piece of gear is everything promised and frankly even better than I had hoped for. I am now convinced that for years I have been chasing flat frequency response at the expense of destroying time coherence.DEQX delivers it all. Bravo DEQX."Ray Weikel, Director of Marketing, Audio Business Unit, Logitech *(Note: these were some of the earliest Heils, considerably modified since)Abbey Road Studios"We are mainly using DEQX Calibrated™ for fine tuning the low frequency issues of the room..."Peter Mew, Senior Mastering Engineer, Abbey Road Studios, UK "Simply awesome, both in technical performance and sound quality…""I just inserted a DEQX in my system. The results are simply awesome in multi-way configuration. I must say that the unit is exceptional. The benefits are very substantial. Driver integration, polar patterns, perfectly coherent spectral energy etc. give incredible acoustic results, certainly the best I have ever achieved with any similar device.If you love piano or large orchestras playing a soft and wide range part, you won't want to go back. I have a unit in my system right now and it is simply awesome, both in technical performance and sound quality. This is definitely a huge step forward in sound reproduction."Andre Perrault, Senior Film Mixer, Technicolor Sound, Hollywood "A product designed and built with passion…""DEQX produce a great product, back it up with a great service, prompt intelligent question responses, a thorough manual, and regular CUSTOMER RESPONSIVE product updates. All software is in a constant development phase, including free hardware bios upgrades. A real tool, and a product designed and built with passion..."Graeme 'Graz' Keet, Owner, Perigee Speakers"A must have…""For all the things it does so well—preamp, speaker correction, electronic crossover, room correction— it is a steal. For the insight it provides to loudspeaker design and set-up, it is a must have."Brad Nurnberg, Audio Installer"Thanks very much for a fantastic solution""The system brings the improvements I hoped for. It cleans up my midrange, and the bass is now fuller and faster than before. The device works perfectly. Just like the installers manual. Thanks very much for a fantastic solution!"Harry Engwirda, Audiophile"The results are remarkable!""Does it work? Yes. I can attest to the fact that the results are remarkable! The DEQX process brings about an improved and more detailed stereo soundfield, a larger sweetspot, a stronger phantom image and an overall improvement in, well… clarity…Exciting times."Chris Holder, Editor, Audio Technology Magazine "The PDC lets me hear these changes; not just measure them""I am using the PDC as a development tool. While I have used the unit to hone the DSP-based crossover for the Legacy Helix speaker, it is also very useful for creating target functions for passive crossovers. As I develop new drivers, I am better able to evaluate the effects of subtle changes in Cms with various driver versions while incorporating optimal crossovers.Lobing effects are also readily contrasted by comparing two channels. The bottom line is that the PDC lets me hear these changes; not just measure them."Bill Duddleston, Co-founder & Chief Engineer, Legacy Audioreturn to top
