Empirical observation I can do by using my ears which although I am an old cantankerous getting closer to death which is a lot closer than birth. I been on this planet for some time now. I should get my OAP bus pass fairly soon. I got Grandkids  &  and Great grandkids on the way. So please do not for one minute I am a "Hater" a "Troll"  Having a different opinion in a situation like this is a bit like being Peer Reviewed  Topology analysis is my field. In both Acoustics & Linear Electronics. It took a while but I have studied both academically electronics is not something I do much of nowadays I can hear fine but I have been wearing glass Since age 40 so basically I can see it as well as I did. But I can spot a mishammered Concert grand  Apparently that is quite a feat as my internationally renowned piano tuner friend he is in the top 5 for tuning your priceless 400yr old piano type instrument   I tell you this so you may understand I can hear very well  I have studied the topology of Paraflex I not so au fait which which is  which but they function from common principles. So really no differences in them at all from a principle standpoint. It behaves just it's Topology dictates it must. I find most things adhere to that  "Form follows Function" Things or devices in this sound as the form dictates.  If you have any reservations as to the validity of that I can offer further examples or explanation of this. So Paraflex sound like Paraflex. I have my doubts on the sonic abilities of Paraflex. I would quite like to have the opportunity to try one out at my workshops. I am as I know it would upset people due to their insistent request to base my opinion on actually having heard it.   So I will offer no critique until I have This is not really necessary for me but others think it is. But if an observation is offered by the poster on this thread of what he finds. A good design will stand scrutiny. And opinions positive or negative. If banning such people for giving negative just that It does not mean they are "Banned"silenced or disregarded That was Twitter's biggest issue.  I make at this point any agreement with anyone. Seems the protocol requires I listen 1st So I will asap I am sure Ben Wells can help there perhaps. And bear in mind the truth is the truth even if it is an uncomfortable one

Hi kinda nice to have just joined.

Haven't been on the forum in years, come back to ask a simple question and so pleased to see that there are threads like this keeping the old vibe strong

Almost brings a tear to the eye....

Almost

There are some trends present that I expected to see, but I want to gather my own data before drawing any conclusions. Luckily, that might well be happening this weekend so… watch this space Edit: in the meantime, some folk might have missed the discussion & modelling I did on the big boy Paraflex back at the start of this year. Here’s that old thread: https://forum.speakerplans.com/skram-vs-c2e-subwoofers-info-research_topic106775.html

Ive had turntables placed directly behind the stack with no isolation pads and no issues while everything in front was knocked off shelves and what not. How ever you guys want to perceive this or start a disagreement war like the rest of this thread is, do your thing. But id like to know what the test results find.

That might be something to do with the rather steep roll-off before the resonant frequency of the tone arm & chamber under the platter

Also there’s a whole wealth of psychoacoustic research and other fields that clearly show we are massively fallible & subject to bias. Particularly in the field of auditory masking, which is literally how lossy audio compression works. I’ve read too many books & spent too many hours on seminars with waaaay smarter folks than I to believe otherwise. Floyd Toole & Sean Olive call this the Circle of Confusion, and I fully recommend everyone interested in sound watch Toole’s presentation on YouTube about this sort of stuff.

I also know someone else has measured C2E Silver in equi-temporal alignment from the acoustic centre as I suggested back then, and found the rear rejection to be about the 5 dB I predicted. But since I have four microphones and an audio interface with 8 preamps, why not double check.

I wasn't disagreeing mate, just adding something
