Placement tips for Synergistic Research HTFs
thanks  
resonance at 500 Hz using headphones - maybe need a different DAC?
I have found that some DACs or systems emphasize the fundamental tones, more than others. As a test case I use Joe Cocker: Seven days, on his Sheffield steel album. This is a great track, with Sly and Robbie on drums and bass (if you want to defin...

Besides the wide disagreement in this thread, what is the cure, I note the absence of attention to the problem. What exactly was bad, before, that was improved by resonators? For example, was it distortion or limitations in the original recording,... 
resonance at 500 Hz using headphones - maybe need a different DAC?
A tone from an open string bass guitar, or guitar, tends to sound louder than a closed string further up the neck. Some DACs seem to give this fundamental sound more preeminence than others. But maybe not relevant for choir music ca 500 hz.

Thank you, interesting, I hope you solve the problem!  
resonance at 500 Hz using headphones - maybe need a different DAC?
I was thinking, DACs do have some distortion, and I listened to a 500hz tone, thinking maybe I could recognize something. Especially in my ’sharpest’ DAC. What do you mean by ’resonance’? A hum at 500 hz? Echo? Distortion? Or that the fundamental ... 
Improving a stone rack
I read somewhere that Duke Lejeune of Audiokinesis wrote about damping - "as little as we can get away with", or similar- in the context of bidirectional speakers, like I have. This type of setup makes the wall behind the speakers even more critic...

Straight up aluminum - interesting suggestion. Reminds me of how I tried to dampen the 10 kg alu platter on my record player, and found that I preferred "real" to "pleasant" - no damping. So platter mats and DIY platter damping were dropped.  
Improving a stone rack
Yes, good advice. I have them adjusted to a third to half compression. I use three feet under the lighter components (Teac, Hanss) but the Io power supplies need four feet to avoid cabinet stretching I think. I will soon try them under my MA1 amps... 
Improving a stone rack
Three sets of Nobsound springs have arrived, so I am testing them under various components. They need to be tuned, so I am taking out some of the seven springs in each foot below the lighter components, so they 'sag' down appropriately. The jury i... 
Improving a stone rack
With Sidsel Endresen and Bugge Wesseltoft: Try, on their Out here album, 2 x LP at 45 rpm, it is like vocalist Endresen is here in my room. On other less good recordings, like Jefferson Airplane: Wooden ships, from Volunteers, and Doors: Riders on...

At last, some clear progress. The record player is clearly critical. A combination of better feet (Cerapucs) and better power cord (Gutwire) seems to be what the doctor ordered. My wife agrees. The effect is as if the artist comes closer, I can he... 
Improving a stone rack
So far, raising components on footers has worked very mildly positively, in the rack - now trying the Einstein preamp on Walker validpoints and the Hanss player on cerapucs. So far, no dramatic effects, maybe a bit, although subtle. I have some la... 
Improving a stone rack
I am testing  Cerapucs under the maglev feet on the Hanss T-30 record player. An improvement? First test: yes, maybe. Slightly more open, detailed treble, and better timbre? So the pucs stay, for now.       
Improving a stone rack
Wool carpet testing - not conclusive. Maybe I prefer the naked shelf. It is not like a big TV screen between the speakers. The rack also acts as a diffusor. I will investigate - some damping of the wall, the shelves, etc. seems ok. And I will expe...
