Acoustic Room Treatments vs DSP

Bonzo, you will agree that the software approach will be more "purist" though, if you want to retain as much of your favourite Dac as possible.

The new DSperker looks verty interesting.
The AM 2.0 was very good for bass issues and of course comes with mic in the package. Very turnkey approach..

I would agree that only theoretically. If you set it up through software without expertise and I set it up through a box with expertise, the latter will sound better. My point is these things, unlike plugging in an amp/dac are so complex for a newbie that best to take the approach where you have expert help. All sound great.

Thanks Norman. As always, you bring a wealth of info to the subject. Sortware DSP is definitely a more pure path of correction. But it certainly has a stiff learning curve. Another product I have used it called Coneq from Real Sound Labs. They offer both software and hardware paths of DSP correction. Plus you can get product offering 4096 to nearly 10,000 taps of separate frequencies !!! Very powerful and adaptable. But I believe they only operate up to 96k, like many others do. I would prefer a system that can handle up to 192k files.

I spoke with "Dallas" several months ago, and thought he was going with Acourate over Audiolense ?? He said Audiolense was a bit easier to program, but Acourate had more capabilities for his use. Maybe he has changed his mind ? Thankfully, there is much more R & D being invested in DSP these days. For this, I am thrilled.

Nice, Jerry. I have never seen that offering before. 24/96 is a lot though, so that alone would not put me off.
DSPeaker uses a form of artificial intelligence in their DRC software and a powerful processor. They are a subsidiary of VLSI Inc, so hardware is in their DNA too. Their new 24/192 will be interesting and as with the AM 2.0, they have dumbed down the process, so that the learning curve is very smooth and shallow.

Miska (Mr HQ Player), says he does DRC in DSD. I started a threat at CA to see if he will elaborate more, as that too is interesting.

No doubt Dirac is far cheaper, but Dirac does not give you SAMification.

You could get Devialet electronics with an already SAMed speaker and then run Dirac as a far more cost effective solution...or wait for the Kii 3!

Does Dirac adjust for the time domain? Kii does and Goldmund is obsessed withe the Time domain. See my youtube link in this thread. Like Frank Muller watches, i think they consider themselves the "master of time". LoL
Click to expand...

Norman items like Devialet are way out of my budget. But in reading the Dirac live technical description it appears they address time domain, not sure how it works. Technical description | Dirac Research

I however like the box approach of the DEQX and DSPeaker as to get away from having a PC involved.
 
Fair enough Chris. The smallest Devialet (D120 used, may not be that much). The SAMification potential is very nice, if you have the right speakers.

Example for $4K: https://app.audiogon.com/listings/s...5-09-05-integrateds-33701-saint-petersburg-fl

This could replace your HUGO, Teac, Vincent and W4s...though I see you have 2 systems. Not sure of the Usher or Vapor are Sammed yet.

The Dspeaker can act as an analog preamp and Dac too (PCM only) and use Toslink/USB/ coax and AES. It comes with wall wart, so a good LPSU would be advisable to get (12v DC IIRC). It certainly is easy to use and really manages the bass. There is a great review here that explains much;

I like PSPeaker is using artificial intelligence. I think that is the only kind, when it comes to audio....lol.
 
Chris - Norman's suggestion is what I've been telling you for a long time. If you can squeeze out a D200, then you can expand to a 400 down the road. If you have the Devialet, you think you just hit a home run $$ and sound wise.

Hi Norman and Bonzo,

If I went for a digital only box that goes in front of the DAC, I would like one that utilizes microphone room equalization. Is there such a beast out there?

Best,
Ken
Click to expand...

yes Ken - you need a mic and USB interface or FireWire interface to measure your room for use with Acourate, Dirac etc
 
Fwiw - I can assure you that it is straightforward to use even Acourate. I am by no means a techie but had no problem using all the standard features in Acourate following online instructions. I would struggle to build a time aligned, linearised, 3 way crossover with room correction though.
 
I have a feeling DSP will be the next frontier in high end audio. Traditionalists like me will go kicking and screaming...but it's coming, whether we like it or not. Major emphasis on big ugly room treatments are likely to go the way of the dodo bird.

I'm not sure how the Devialet SAM technology compares to the products like Dirac, DSPeaker, etc. but I'm totally smitten with SAM on my Focal Scala V2's. To put it bluntly, it removed the last little "bitch" I had with them in my room.

Let's face it, once you get beyond proper speaker placement, most rooms are still a problem. Most rooms require some TLC to get just right....not too hot, not too cold....wait, no, that's something else. Not too dead/not too lively.

As DSP continues to advance in terms of technology both outside the speaker and inside the speaker, are we reaching a point where behemoth treatments will go the way of the Dodo Bird?

Case in point: I had the opportunity to hear the Avantgarde Zero XD's. The left speaker was jammed into a corner and the right speaker was out into the middle of the room. I thought for sure this would not sound good. Boy, was I wrong. It sounded incredible. I listened for over two hours to be sure - both digital and analog. The depth of soundstage, the precise bass, the clarity was incredible.

With regards to DSP, there isn't really a good way of incorporating DSP with vinyl - unless of course, you digitize your vinyl (GASP!). But digitizing your vinyl is precisely how the Devialet handles the analog signal, and you know what? It sounds DAMN GOOD and offers incredible customization not found in many (any?) analog phonostage.

I kind of think DSP will be the next wave to hit hifi over the next 5 or 10 years.

What do you think?

I briefly fiddled with room correction when I had Emerald Physics speakers. The room correction that Clayton Shaw was using at the time produced a modest improvement. There is a lot to be said for correction in the digital domain if you have a crappy room. At some point, it may prove to be a viable alternative to physical treatments. However, its hard to circumvent the physics of sound and vibration. In my limited experience, there is no substitute for a properly engineered room sans aftermarket room correction gizmos.

If you truly want to circumvent the room, headphones are the answer. Once the engineering of phones evolve further, it may make the old stereo paradigm look silly.

Clayton hasn't been associated with Emerald Physics for almost 3 years now. I would suspect he was also using something pretty low budget. DSP has made some nice strides in the past 3 years and some of the top tier products like DEQX are really impressive.

I know it was not the DEQX. It was part of his Spatial software. A friend of mine used his most recent software offering (Dirac), and it was not copacetic.

Again, you will be "Gob-smacked" if you are the average reviewer with a crappy room....which if u look at photographs, seems to be the norm. Also, Atkinson thinks digital rips of vinyl are as good as the real thing. Who knows with him.:skeptical:
 
In my opinion, digital processing doing phase shift and it is worse than bad acoustic. Sound looses details and spatiality. Best sound is from single A class tube amplifier and good horn speakers without crossovers if you are passion.
