DEQX


I’m very new to this. I read several posts concerning deqx, but am still confused and wonder if it’s for me. To all who have first hand experience, pls give me your thoughts and experiences. I was mainly looking for a room correction device, but see the new model “5” has all I need to stream. My son has been trying to get me to try streaming, but I have resisted. Looks like this may be a good reason to incorporate it into my sources. From what I’ve read, seems like a very complicated set-up procedure. Also, where would it be placed in my system? I have a TT, CD player, a phono stage, line stage and two monoblocks. Last question: since I do not stream, will a laptop also be needed?  BTW-I have Wilson MaxxII’s. It seemed in the posts, it mattered a great deal, which speaker you’re using.

@Handymann,

My experience and opinions just represent one data point, of course, and certainly there are those who would prefer to use a DEQX in conjunction with a traditional line stage.

But FWIW my bias, generally speaking, is to place the burden of proof on adding anything to the signal path that isn’t necessary in terms of functionality. And I’ve been sufficiently happy with the sound of my system that I don’t have any desire to consider adding a separate line stage. Also, finding a place to physically put one in my system, which is in my living room, would be problematical from a practical and aesthetic standpoint.

In addition to numerous other system and listener dependencies that would enter into a preamp/no preamp decision it wouldn’t surprise me if in some cases the tradeoff would hinge on whether the DEQX’s balanced or unbalanced analog inputs and outputs are used. I’ve never tried the balanced analog i/o’s in conjunction with critical sources, as my power amp, headphone amp, and my one critical analog source (a Herron phono stage) have only unbalanced interfaces.

Another thing that may be relevant to that decision, depending on the particular system, is that a DEQX doesn’t provide much in the way of gain. See pages 165 and 166 of the manual. And in fact the default/as delivered positions of the internal jumpers which affect that produce a **negative** gain (-6 db) from the unbalanced inputs to the unbalanced outputs. As you’ll see at the bottom of page 165 of the manual that is done to provide headroom for equalization (and for speaker and room corrections, although that isn’t explicitly stated). Although changing the position of an internal jumper can raise the -6 db to approximately 0 db, while retaining the same amount of headroom (which I’ve done, btw).

Finally, regarding the possible use of your DAC in conjunction with a DEQX and/or your Calypso preamp for listening to CDs:  I’ll mention FWIW that while I found connecting the AES/EBU output of my Bryston BCD-1 CD player to the AES/EBU input of the DEQX to be preferable to using the BCD-1’s internal DAC in conjunction with the DEQX’s A/D converter stage, the difference wasn’t huge, and in fact was smaller than I was expecting.

@handymann Larry is a wizard. During your test period Larry can allow you to hear the DEQX in different configurations so you can figure out which one best suits you. I will be surprised if you don't end up keeping the unit when the 21 days is over. Larry setup my system and I use both an external DAC and an external preamp. It works like a charm.

@astewart8944 , Steakster, Uberwaltz, and Almarg: Thanks so much for your continued advice. I was a little concerned about the output voltage of the PreMate+, but was glad to read no problem with putting it in series with my linestage. I will probably wait till after the holidays, so I can devote more attention to it.

Thx for the mention but not much advice from myself I am afraid. I am pretty much in the dark on this but very interested party for a later reincarnation of my system.

Pretty sure Almarg is the resident authority on this tech right now.
@astewart8944: How did your combo with your external DAC and preamp work out?  U said it’s good. Pls expand on your experience.                                     Steve
