4. Linear Phase digital crossover filters and time alignment.
Let's not bury the lead. Greg built (essentially) a diy Everest system with components he personally designed and chose to use DEQX crossovers not just for the Everest but also the K2 in his system. That seems like high praise indeed.
I remember reading this thread (
http://www.audioheritage.org/vbullet...highlight=Deqx) started by Ken Pachkowsky about his experience with the DEQX and at the time thinking "this is unlikely". But recently I met this fellow Ken mentions and got to watch him tune a custom 3 way. My friend who built the system is an experienced audio engineer who designs and builds good equipment, is very competent in all things audio, and regularly writes for an audio magazine. He worked a long time with the DEQX software and barely got the system to the point of being listenable. In just a few hours, this DEQX tech had that system sounding amazing. It was something to see/hear. Perhaps Greg is as good using the software or maybe even uses the fellow to help tune the system? I'd be curious to know.
