    Trying the ZR Acoustics Panels

    That doesn't mean there aren't better alternatives. Lots of well name recording studios use building insulation based products, which I can't stand having had many years of experience with various types of rooms (recording studios, listening rooms), yet they are widely used.. Listening a...

    What's in the panels they have covered with fabric? What material are they using?

    Trying the ZR Acoustics Panels

    With diffusion, there are something like 5 or 6 requirements for a true diffused sound, but to get anything that's going to do anything in the low frequency range, they have to be rather deep. I can only see these things being effective (at some level) to more higher frequencies than lower mid...

    Trying the ZR Acoustics Panels

    That's not a lot of wall coverage for treatment. With just 4 panels, you're just treating a VERY small percentage of the wall surfaces in the room. How close to the front wall are your speakers? Have you tried puling them out about 3 to 4 feet away from the rear wall? Those panels aren't...

    Trying the ZR Acoustics Panels

    Have you done any room measurements? What's the dimensions of your room? LxWxH? I'm worried that your room might have a lot of low frequency problems below 100hz that those panels are not going to do anything to solve low frequency problems and the dimensions look like you might have a lot of...

    Trying the ZR Acoustics Panels

    Sounds like someone is just selling strange looking that's scattering the sound in a certain way.... I'd like to see measurements to see if they do anything to low frequencies below 100hz because I doubt a panel that's only an inch thick with grooves in them that are only less than an inch thick...

    Trying the ZR Acoustics Panels

    Yeah, quantum got me too. The thing with nearfield listening is you still have to have speakers/listening position away from any side walls and ceiling. And a lot of people don't realize that they are still too close to a wall surface when they are doing near field listening. I think the...

    Trying the ZR Acoustics Panels

    I read up on the ZAcoustic marketing and I was actually more confused. they don't show any measurements of any of their products. I'd look at what Acoustic Fields is doing. I've been in a demo room of theirs about 8 years ago. I just don't have a decent sized/shape room worth treating at the...

    Trying the ZR Acoustics Panels

    I read their information on their website, I personally think it's 99% hogwash but I'd have to look at before and after measurements and do my own listening tests. I would think that if those things actually did anything, you'd need pretty much 100% wall coverage, not the postage stamp sized...

    Did Dennis suggest moving the equipment rack to the back end of the room?

    Dedicated audio room build thread aka The Big Dig

    How was your idea of "acceptable room treatment" vs what Dennis was suggesting? I've had many discussions with Dennis over the years and I was fortunate enough to listen to one of his rooms. My understanding of room treatment has changed throughout the years as I was able to either use...

    The argument for/against room treatment

    How many rooms in people's homes were actually designed for audio? Only those that are custom built that had an acoustician involved with the design of a dedicated listening room, and hopefully they were able to design a great sounding room. Look at wall construction and room dimensions. 2x4...

    Dedicated audio room build thread aka The Big Dig

    I would suggest checking out MIT Cables and obtain some loaners of their various cables. I've been a long time fan of MIT and have only seen improvements in their deigns over the years.. They have a loaner program so you can get a pair of cables for 30 days, and then send them back and get...

    Dedicated audio room build thread aka The Big Dig

    Great room. I stumbled across Acoustic Fields about 8 years ago. I checked out the demo room they had back then and was simply amazed at how his rooms sound. I can only imagine that your room is simply amongst the best in the world.. What did you end up doing with the flooring? Also, is there...

    Should the 1st Third of the Room (Speaker-side) Contain the Most Treatments or Spread Evenly?

    Of all of the room treatment companies I've dealt with, I found one that really does a great job in recommending what treatment to use, where to place it and they can give you a strategy in terms of getting what will give you the best bang for the buck and what to buy later when you have more...

    MIT vs Transparent cables

    I have only tried one pair of Transparent interconnects and they were The Link which are entry level cables. I did enjoy them EXCEPT. The problem with that model is the connectors. They are VERY small and they are VERY tight connection which is good, but unfortunately, I damaged the cables...

    MIT vs Transparent cables

    They use noise filters on their power cable products and their "articulation" filters for speaker and interconnects. They aren't a Zobel design, they have their own design that has a patent. What frequencies they design them around are based on what frequencies aren't articulating properly and...

    MIT vs Transparent cables

    They aren't tuned to hundreds of kilohertz. They are tuned to frequencies that are related to musical notes and/or their relative harmonics, but their highest frequency isn't anywhere near 20khz. I think they kind of end around 10khz, but I could be wrong on that. They are definitely related to...

    MIT vs Transparent cables

    With the MIT cables, how long did you have them? The reason I ask is whether or not they were burned in long enough. Due to the dielectrics they use, they typically take about 100 hours or so to fully burn in. Things tend to change after they've been fully burned in. For me, I've never heard...

    MIT vs Transparent cables

    A few things that bother me about Ethan's test. First off, he hasn't given his box to any cable mfg. for them to examine to see if there's any monkey business going on. Second, he turns a knob to achieve a desired result, that bothers me a LOT. Thirdly, his test bench has a TON of noise and...

    MIT vs Transparent cables

    Actually, they aren't EQ boxes. An EQ box would have to be wired in series to act like an EQ, but these networks are NOT wired in series. They are wired in parallel so they create each network for a specific very narrow band to help that frequency "articulate' to it's best abilities. They...

    Doctor's Orders-Part Two-The New Listening Room Of Steve Williams

    I haven't used Roon, but does it support DSD or do you have to convert to PCM? Just curious. I have played around with JRiver and found it to have a very confusing interface/setup.

    SR HFT + FEQ ... Voodoo or ???

    I personally don't like it when someone markets a product saying that it's Turbo Charging my system. Maybe i want to Super Charge my system, or maybe I want to add a Blower or maybe I want normally aspirated. Or maybe I want to use nitrous. ;-)

    SR HFT + FEQ ... Voodoo or ???

    How many of those things did you use? what was the room dimensions? And did you use that box that "turbo charges" you system? where there specific frequencies or a frequency range that they were affecting? Thanks!

    SR HFT + FEQ ... Voodoo or ???

    My suggestion is to talk to an acoustic engineer directly since they are trained about room acoustics and they typically measure the room with a variety of measurement techniques. If you really want to spend your money, you can get a relatively inexpensive measurement mike, some room...

    Oh, so you eat moldy bread when you get sick? last time I checked, moldy bread makes you sick. And for want it's worth,my doctors don't prescribe antibiotics like they used because there is proof that they can cause other problems.

    Synergistic Research HFT

    Steve, you've mentioned to me several times that I'm preaching to the choir about measurements, yet others don't view things that way. if you like having people promote an unproven technology that's kind of expensive, then that kind of makes me feel that you don't mind people doing it. I can...

    Synergistic Research HFT

    Let me ask you a couple of simple questions. When you go to the doctor's office and you have an illness, are you going to take a prescription drug that hasn't been tested as to it's effectiveness in treating that illness you have? Think of your room acoustics as having an illness. How would...

    Synergistic Research HFT

    Well, based on discussions with acoustic engineers, it's not a valid form of room treatment that's been proven by any form of measurement, so if you THINK it does something and you want to blow $1500 on it instead of buying REAL, HONEST to GOD room treatment, then go right ahead. You'll...
