Sorry,but the prices are too high.I will buy one when price came close to 1000US$.

Should correct entire playback chain.

Someone once said that the future is digital. One might add that the present seems quite digital too. Some of the big caveats of our analog domain are related to the imperfections of analog filters, transducers, and room interactions. It seems the digital domain has some advantages here, though of course with its own peculiarities. I am of the profound belief that the potential of digital audio will not be realized until a completely digital system is put together. The only missing link is the digital loudspeaker, although they are in the working, as rumors say. Digital amps or power DACs are working very well (cf. TacT); the same can be said of digitally filtered loudspeakers, though with analog amps (cf. the DSP series from Meridian), digital signal-processing is cheap. The only thing missing is putting it all together with a high-resolution source (i.e., 24-bit and 96-192kHz sampling). Who will be first with an all-digital, high-resolution active system? P.S. My old Thorens is alive and very well, thank you.

It improves the sound radically, independent from the systems and enviroments. I have tryed Accuphase DJ-28. Fantastic results.

Anything that solves the boomy bass problem in my room without compromising other aspects is welcomed! Price should be $1k or below, though.

I've heard it and we are working on it. This is going to be the basis of a quantum leap in audio performance in the home at prices that will be very reasonable two years from now. The remaining weak link will be the loudspeaker and the loudspeaker's interface with the room. Digital EQ will help but will not completely overcome poor design and poor setup. Digital room correction will really bring the music home to a wide range of consumers and should swell audiophile ranks. Regards, John Meyer

I love vinyl!!! Given my current system, I cannot envisage a time when I won't be listening to vinyl. But the idea of digital room-correction does appeal. The idea that, for a couple of thousand dollars and a few hours with my PC programming the box for my environment and my speakers (as suggested by the Perpetual Technology box), I can dramatically improve my sound—who wouldn't be interested? Given the rapid increases in processing power, I can see in the near future an A-to-D stage that will allow the integration of my turntable without inducing digital artifacts. Should this device be realized, there is no doubt that my future will have a digital room-correction device in it. In the shorter term, given my CD collection, it is likely that one of the first-generation digital room-correction devices will have a role to play, if only to upsample my CDs and improve the sound of my system just for CD & DAT.

This is the smartest thing that's happened in "high-end" audio for a long time. Much better than green markers, expensive do-nothing cables, and the like. Now this technology needs to be offered with more than two channels.

Are they going to digitally alter the sound to match my ears, too? Isn't this taking things just a little too far?

I'm interested, but not at today's prices. If someone would sell a good five channel digital equalizer for about $1500 then I'd be very interested.

Diminishing returns knocks me out of that kind of product category.

Here, in order, are the determinants for sound quality in a stereo system: 1. Recording 2. Speakers 3. Listening Room 4. Amp 5. Pre-amp & Sources 6. Connections With speakers so high in importance, anything scientifically rational to enhance their accuracy will be most welcome.

I have had a SigTech for a couple of years. I look foward to SigTech's 24/96 upgrades when they become available.

I have a Z-sys , which is a fantastic help in the low bass region. A TACT or Sigtech would be very nice , however I will wait a while as I forsee the price and power of such units reducing dramatically.

I'm "interested" in this technology, but then I'm interested in a lot of things when it comes to audio, and it's not at the top of my list. I'll be more likely to buy when less expensive, trickle-down products come to market.

Sure I'm interested in a product that could take my listening room's effects, out of my listening room. But my system currently sounds as good as my BUDGET will allow. And for most of us, isn't that the determining factor?

This seems very promising.

I was present at a demo of axial room modes and their effects on the overall sound, and it was very dramatic. It was given at CEDIA by Dr. Floyd Toole and made a believer outa me! It was 5.1 (vs. stereo), but the dialog was muddy before EQ and crystal-clear after. Very impressive.

Stop buying expensive cables and gear and focus on what is really the far most important unit of the audio chain: the listening room!!!

Not only do I want to see products that statically equalize the system to the sound room, but also dynamically blot out the kids jumping in front of the speaker, the wife running the TV, and the telephone ringing. Oh brave new digital world!

Eventually, this will be the function of a good pre-amp/processor. Here is how the process will work. -the processor will have a RTA and microphonne that will analyse the composite room and system response. - the pre-amp will also have a parametric equalizer in the digital domain. This will compensate for system/room response and return a flat 20-20kHz result. - the pre-amp will process all equalization (and crossovers) in the digital domain before using the DAC's to convert to analog and send to an amp. A flat system/room response may not be the definition of the ideal a/v system, but it creates one hell of a foundation. Personally, I cant wait.

Only the high price has kept me away.

Very long overdue. How many of us have tried to equalize a system with different cables? Pathetic and expensive. Cable prices have done more PR damage to the High End than any other ingredient. Outsiders just laugh. And with good reason! Welcome, digital EQ.

My Room has alway been the part of the equation I can not get right and still live with my wife

like it or note, it is the future of audio.

I have got a long way to go with rebuilding my room before I spend any money on digitally EQing it.

My early experiences with active equalizers were not very successful. The current digital versions certainly sound more interesting, but are a little out of my reach at their current prices. It is certainly cheaper than a new house as far as room treatments go!

Bring it on. Assuming real world affordability and of course that it actually does make a worthwhile improvement to the sound.

Many years ago (probably around 1979) I heard a demo (in a large room at some electronics show in Lansing, Michigan) of a gizmo that did this by playing pink (white?) noise through the speakers and taking readings at one to 10 locations in the room using a specially calibrated microphone that came with the unit. The results made even the bottom-heavy Altec Voice of the Theaters sound palatable. I think this was a DBX unit, and I know I couldn't afford it then. I wonder what's going on now, and whether it can correct for seconary coincident room modes without damaging microdynamics and imaging, and at what price?

I would be interested in testing this device in my systems to decide if it has the merit to be a permanent member of it. Any technology that enhances the listening experience deserves an ear!
