H.E. Pennypacker Posted November 23, 2019 Share Posted November 23, 2019 (edited) Ok... every ‘this next step will fix it’... horse s***... room correction. I’ve not heard an “endgame” system sound like this (though I’m sure plenty do, I’ve only heard that level at shows and stores) ... simply astounding... I’m still shocked... bass vibrates my chair, but also isn’t there. 3D vocals, instruments... separated, but one. In the words of continual sweat shop operators... JUST DO IT!

Snoopy8 Posted November 23, 2019 Share Posted November 23, 2019 I think you are referring to the C658, please change your title. What is it like with and without Dirac? Did you pay for the full license? Link to comment Share on other sites More sharing options...

What is it like with and without Dirac? Did you pay for the full license? I set it a challenge... I used to have the speakers 1200mm from the wall (from the rear of the speakers), now they are 500mm, they are still 1100mm from the side walls. Without Dirac... Boomy bass, nulls and with flat and lifeless imaging/staging. With Dirac... balanced tone with a HUGE soundstage. 2 Link to comment Share on other sites More sharing options...

Ittaku Posted November 23, 2019 Share Posted November 23, 2019 Once you've experienced good room correction, it makes you wonder why people concentrate on everything else and ignore it, and you can never go back to a system without it. Enjoy. 4 Link to comment Share on other sites More sharing options...
kukynas Posted November 23, 2019 Share Posted November 23, 2019 Game changer? could be, now give me M10 in full width chassis with more power (let’s call it M20 for now) and reasonable price tag and we can even call it end game, I believe I won’t be the only one who would jump on it 2 hours ago, Ittaku said: Once you've experienced good room correction, it makes you wonder why people concentrate on everything else and ignore it, and you can never go back to a system without it.

Unfortunately, there are still many 2 channel purists who refuse to contemplate things like room correction, subs etc.. Their loss! 2 Link to comment Share on other sites More sharing options...

Their loss! I reckon room correction should start with actually correcting (treating) the room, and the speaker placement. Some issues cannot be fixed by signal processing. 1 Link to comment Share on other sites More sharing options...

In a shared environment, it may not be possible, hence room correction is often the only way to tame some of the issues with the sound, as OP has done. 1 Link to comment Share on other sites More sharing options...

It much doesn't matter how you get rid of them... as long as you do. Cars with 3 wheels don't go very fast (and are easily beaten by a car with all the wheels working) ..... doesn't matter if it's a million $ sports car, or a 40 year old rust bucket.

stiben Posted November 24, 2019 Share Posted November 24, 2019 I just read through the manual for the C658. SHD still better for my requirements but a mix of both units would be the bee's knees. My stereo is on my TV so the one area the C658 wins outright is the optional MDC adding HDMI in and out with ARC. But more $$$ I run a HT processor at fixed volume to the SHD's RCA input. 1 Link to comment Share on other sites More sharing options...

The bass traps, carpet, absorbers didn’t do much that I could hear. Room correction through DEQX is a big change. 1 Link to comment Share on other sites More sharing options...

There's a whole lot more treatment that could be done for this room. Those thin foam absorbers won't do much. They could instead be the outer layer of the "real" absorbers - that entire front wall could have 1 foot thick absorbers (acoustic fibreglass or better) floor to ceiling, and 2 feet thick on the sides out to about 2m from the front wall where the curtain starts, plus cloud traps in the corners, and one could go even further than that. The enormous difference this kind of treatment makes would blow the socks off any audiophile. It really cannot be overstated. OP got a taste of this with Dirac but DSP cannot fix some of the problems room effects introduce. Room treatment is the only thing that can really do a good job of it. 1 Link to comment Share on other sites More sharing options...

The batts are self-supporting, plus some 3M temporary hooks to prevent them toppling forward, and that's 90% of the job done. Link to comment Share on other sites More sharing options...

Yup... I get to build a custom listening room when we build the Canberra house (as in somewhere around 6m x 10m)... still astonished at what Dirac has done for a 4 x 3 room.

I understand it's unrealistic for many people, but on the other hand the number of high end systems I've seen in dedicated entertainment/music rooms with little to no treatment is astounding. That's like buying a Ferrari and only driving it back and forth in your driveway. 1 Link to comment Share on other sites More sharing options...

I’ll be upgrading to a high end system when the custom room is built (it will be designed properly and treated). 1 Link to comment Share on other sites More sharing options...
