Is DEQX a game changer?

Wanted to thank everyone for their commentary and posts on this piece.  I have one coming, should be here next week.  Looking forward to getting it integrated.

Wondering if any could share their connection setup.  I’ve been attempting to integrate my preamp into the chain, with 0 luck.  I pulled my DAC and inserted the Premate and am not able to get a signal to pass through my preamp.  Sounds/works great without my preamp, connecting my amps directly to the DEQX, but getting the processed signal to pass thru my premamp, no bueno.  It may be something as simple as selecting the correct input, via the DEQX, though I’ve selected “auto” and every input, via the remote.  Any help is greatly appreciated.

Hi Al and thanks for the quick reply.  Your interpretation is correct.  It does sound quite good without my preamp, but I really like the tubes I have in it, adds a little “warmth” to the overall presentation, so I’m not ready to discard it.  The preamp isn’t super finicky, but confirming that the analog out into the preamp should suffice, has me stumped.

Ok, I won’t throw a “solved” in there, but generally the simplest answer is correct.  I wasn’t plugging both XLR’s from the preamp into the DEQX, just one side; which there was just white noise coming out.  Plugging both in makes it work, along with the sub. 

@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!
