I heard from many sources incl. Variac that it has a no. of deficiencies, primary the analog section, the DAC and clocking according to Oettle, also the power supply.
Then why the f...k did you buy it in the first place.?

Just use the goddam thing out of the box and everything will be fine - or spend the money and buy yourself the deqx for more then ten times the price.

I just find this upgrading advice for a well working unit nauseating.

This site resembles more and more the audiophile c..p you can read on any of the sites - i.e. audiogon et.al.

I believe the concept you are missing is one that I have heard called "stone soup".

I use an unmodified DCX2496 and am perfectly happy to date.

The original stone was only a pretext to start the villagers sharing in a way that they would not have considered without the catalyst of the "stone soup" that they thought they were improving.
I guess the term stone soup does not apply in our case - we actually have a unit that is working - to my ears - very well, which I have used for years and if something wants to "improve" on it - fine.

But to buy a unit that is so "obviously flawed" as stated by members of the golden ear tribe, with the intention to modify the bejeezus out of it?... I am sure I am missing a special gene or two that is at work here...

Hi,

There is no need to modify anything for all who are happy with the standard DCX. But perhaps you are only happy because you never heard what is possible. I'm not an owner of a golden ear and most probably have no audiophile genes but sometimes differences can be clearly heard. I don't want to say that all existing mods are worth being done. But that's life you must know where to go. One way is to believe the higher the price the better the sound. That's not my way.

I guess you are right - I just don't know what I am missing.

I just wonder when I am able to hear all the instruments the label says that are playing, hear the correct tonal colouration of the instruments, hear the spacial separation, hear the voices of the singer that are believably of a singer and not of a synth and this voice matches what I heard on pricier equipment than mine, hear the attack, sustain and decay of each note, hear/feel the drums down to below 20 Hz - what the hell am I missing?

I understand you don't believe in modifications, but I do, ask yourself this, why is it tha DCX is so cheap compared to Dbx rack drive, DEQX etc., DCX has some shortcomings, ie its design is compromised.

We are all adults here so mind your language...if you insist then go elsewhere.

just check the specs on the deqx - then you know why it is more pricey - for instance, it fulfills the function of the src, deq and the dcx all in one box - at least as far as I remember from the last time looking.

If the design is compromised - then why bother? Instead of spending the same price the unit costs on upgrades with rather doubtful results why not get the DBx driverack? The last time I looked, depending on the version, you could source one for 499 - 999$.
Is it just to waste money on upgrading a doubtful product or is it to show those behringer engineers how to do things right?

As I stated - I am neither missing information, nor doI perceive any added information - distortion - when compared with analog x-overs.
I rather perceive an increase in high frequency information when completely staying in the digital domain until output to the power amps, using the src as an input device, deq and dcx as processors.

maybe a new model of DCX2496 is coming out, I got mine for US$212 compared to Dbx rack drive which costs far more, at least twice.

If the upgrade is too expensive then I will not proceed, some of you can afford expensive item I don't and I don't believe it is good because it costs far more.

Furthermore DCX is a proven product with minimal or no bugs(I think). I don't hear that many users talking about(rave) about Dbx here in this forum. DEQX is far too expensive and many features I don't need besides I cannot afford it.

Also remember this is a DIYforum and most visitors here are hobbyists and they enjoy building, tinkering or upgrading through modifying their equipment. Obviously the aim is to improve the equipment sonically, if not, one can learn something, any mistakes ie the mod. etc do not work as expected., then try something else.

There you are, I have exhausted my reasons, if you don't agree, then I don't think I can convince you.

I doubt I could hear the difference any modifications to my dcx might make, but I do understand people wanting to tinker. It's a hobby, it's about fun and learning and possibly making something better than it was for very little outlay. And as another said, this is diyAudio.com after all ;-)

Hi audio-kraut,

It would be helpful if everybody would only write about what he really knows or about his own experience and not about assumptions and what he has heard, otherwise it doesnít make sense to complain about well sounding Ďaudiophileí descriptions. The assumption that everything what is more expensive is better than DCX is simply wrong!
The main difference compared to DEQX is that DEQX supports FIR filters and the price is about 10 times higher.
All of these digital crossovers consist of a PLL (phase locked loop), a SRC (sample rate converter, a DSP (digital signal processor), several DACs (digital to analog converter) and analog output drivers. Beside this there are a master clock and a power supply.
Talking about DCX I would say the PLL, DSP DACs and power supply are pretty OK or itís hard to find something really better. The SRC, master clock and analog outputs are poor, but there exist cheap mods. So with these two mods you end up at a price of less than twice the DCX which is still at least 5 times cheaper than DEQX. With these mods I donís see any component which could really be improved much more even with a lot of money.
If you prefer FIR filters buy DEQX and tell me the sonical difference between FIR an IIR filters. So far nobody could tell me the difference. I only read that itís nearly impossible to hear phase shift and that FIR filters have other problems like pre-echo.
