Is DEQX a game changer?

@Almarg:

Before my session with Larry, I was asked to put my speakers on castors, so we could take individual sound readings of each speaker placed in the middle of the room.  Didn’t happen,  Just took a reading of the listening position, with each speaker in their normal place in relation to the listening position. I was also led to believe I would have to gain access to each of the internal crossovers to achieve the time alignment. Didn’t happen. I should mention my best friend passed unexpectedly the day before my session and my head just wasn’t in it,  Larry spent a lot of time setting up my deqx, but didn’t go through many of the steps I thought he would.  

Sincere condolences on the loss of your friend, Steve.

Not moving the speakers to the center of the room for the speaker calibration measurements certainly figures to be a reason the PreMate didn’t provide much improvement. I had pointed out on 9-5-2018 in the DEQX thread you had started that might be an issue given the 410 pound weight of your speakers.

Again, my condolences. Best regards,

I'm not sure why he didn't want to take the time, to fully set up my Premate, but it definitely had a bearing on the outcome.
