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,
-- Al

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.

handymann,
That experience is discouraging.  I was considering a DEQX for a 2 channel area but don't have the time, patience or expertise to do it on my own.
I just installed a Lyngdorf MP-50 (with RoomPerfect) 16 channel processor in my dedicated and treated theater and am very happy with the improvement over my Marantz-8802A.
For a separate 2 channel system, I was thinking about the Lyngdorf TDAI-3400 integrated for RoomPerfect and am intrigued by the HDP-5.
They are in the same ballpark cost-wise and I have amps to use
with the HDP-5.
Without (dedicated) support the HDP-5 is probably not a good option for me.

@mlee I will concur regarding your sentiment with the time dedicated to interfacing with a DEQX product, but this is a very small price to pay, given the end result.  I do not work for them, so I’ll do my best to avoid coming off as “salesee,” per se.  

I don’t believe the devices are an apples to apples comparison.  The Lyngdorf TDAI-3400 is meant to be an all in one pre-pro, with additional external support capabilities for Roon and various other streaming capabilities.  I believe it can be used with a dedicated 2-channel system, but you will have limitations.  The primary one, you will have to decide whether you want to utilize the Lyngdorf internal amp and hook your speakers up to that or utilize the preouts to your amps.  Per their manual, it doesn’t mention whether your able to utilize the 1 set of XLR preouts as a full-range signal, it references selecting “the design of the speakers for handling lower frequencies.”  Nonetheless, that may make the choice for you, as you may not be able to utilize it in the fashion you’re intending.  

I do own a DEQX, and it is involved, way more involved than the RoomPerfect configuration process.  I owned a McIntosh MEN-220, which uses Lyngdorf’s RoomPerfect algorithm and process.  Fortunately, the DEQX community, support and “DEXperts” are available to make the configuration seamless, they remote into your desktop while you’re on the phone with them kicking back.  Additionally, how much you want to be involved is entirely up to you, but very, very, very rewarding.  You do have to take the measurements for them, while you’re on the phone, but you can leave if so desired...I had to, so I couldn’t stay for the entire process.  I can all but guarantee you, you will learn about your room, your system configuration, how it’s interacting with your room, subtle things about sound and it’s interaction with the human ear, reflection points and all sorts of tiny variables which make this hobby so fun.  

Larry was mentioned above, that is who I worked with.  He was great.  Once the process was completed, I called him back and we discussed what I was hearing, what I liked/didn’t like and we made some minor revisions.  Not necessary, but we all hear and interpret sound differently, regardless of what a curve is showing us.  I have 3 different settings, for 3 different sound profiles I gravitate towards, all switchable at the push of a button.  In the two years that I’ve owned it, it has been bulletproof and has been, as far as I’m concerned, the single greatest 2-channel investment.  Best of luck in your audio pursuits!
