Equalizer in a Hi Fi system

It is difficult to describe what state of the art imaging sounds like. Obviously, we are all use to hearing our own systems and how they perform. Many of us think they sound really good. Stereo system imaging is for all intents and purposes a surrealistic characteristic and not commonly heard in live performances. Only a live acoustic performance can generate such an image under the right circumstances. Thus many of us have not experienced this type of imaging. It is something you have to experience. What does being Tasered feel like? You have to be tased to know. The problem for audiophiles is getting to that level of imaging performance is really hard. Having EQ capability is a vital part of it as no two identical speakers have the same amplitude curves and they have to be identical to generate the best image.  

Very interesting. Rob Watts has answered questions like this and has made himself very available on head fi. Will take this to there.

ive directly compared treble boost on neutron music player (also 64 bit processing) with Charter Oak analog. I liked treble better on CO in this scenario as well. Is neutron music player’s processing as resolving as DEQX?

I underline the word i will comment about imaging ...

It is true to say "surrealistic" because because ANY stereo system at ANY price is defective because of inevitable crosstalk between the two speakers ...There is a loss of spatial information ...It is a fact in acoustics ...

Only the BACCH filters of Choueiri can correct this defect ...No need to own one to read his acoustics papers and understand why this is so by the way ...

I decreased a bit my crosstalk level mechanically with my small speakers on my desk and the imaging improved a lot ... I keep this not esthetical device between the speakers so good it is now ...I cannot recommend it as a permanent device but for an experiment ...Then i verified what Choeuri talk about ...

I know pretty well what a good imaging is with my AKG K340 , because of their acoustic resonators and their two cells which act as speakers +subs, their imaging is better by a great margin over any other headphone i listened too ...No comparison with my 2 Stax, nor my magneplanar nor with any of my others dynamics one ...

Then my dear mijostyn i doubt that your system with no crosstalk DSP correction as the BACCH filters , i doubt that your experience of imaging make you the expert on this because you own a good EQ system ...And because as you said no true audiophile own headphones which is preposterous claim in itself especially when we know what some headphone can do a few TOP among them ...

And i remember you claimed in a post above that among the 4 better system you heard in all your life the first was set together without pro EQ and by randomness and no knowledge of audio by your friend at the times ... The meaning of this anecdote say a lot about your imaging expertise to me ...

It is impossible to experience a very good imaging by chance in a living room with speakers system picked by someone knowing nothing in audio ... There is too low probabilities ....

i never experienced a good imaging before understanding a bit not only of  acoustics basic but electrical and mechanical control of the system workings and even more less well known facts about audio system ... And it was true when i listen the other audio system i listened too from average people not bothered by acoustics using even magnepan system ...

There is imaging the average imaging , and there is a more pin pointed and better distributed imaging in space with  some holograohic volume for each instruments  , and there is the BACCH filters more perfect  imaging and spatial soundfield making good headphone and good speakers no more distinctive in their spatial acoustic qualities ...  i never experienced myself the BACCH filters  this  is easy to imagine if you dare to read what it do and if you experiment with a mechanical  even slight decrease in crosstalk as i did or if you go from speakers to TOP headphone where there is less crosstalk effect spatial information increase a lot as with my AKG K340 ...

i found the following post on Head Fi by Rob Watts himself. Founder of Chord Electronics:

”PC's normal calculation is by 64b floating point (FP). There are serious perception problems with floating point as it innately creates noise floor modulation (and other problems too) - and even though the modulation is technically very small, it has in my opinion very serious subjective consequences. This is the primary reason why many Mojo 2 users have commented very favourably on the improved sound quality of Mojo 2's UHD DSP against conventional EQ. In my case I use aggressively noise shaped fixed point architecture, and this innately has absolutely zero noise floor modulation. Going from 64b FP to 128b FP will get you closer, and 256b FP almost converges to fixed point noise shaped operation.

But to say that solves the limitations of windowing is just plain incorrect. The wrong algorithm creating transient timing errors will always be the wrong approach irrespective of calculation accuracy.”
