Room treatments - GIK Vs Acoustimac
Milpai, The less you use to 'correct' the room reflections the better. "...I want to get my system to a point where even when I move my head from the center position, the vocals should still appear to come from the middle. Is this possible? H... 
Ceiling diffusion
We have seen many audio jobs that were over done. Some of the rooms were as dead as a echo chamber. The less - the better and many of the acoustic panels are as stated, hard to use and cost far too much. Let us know how your project works out. 
Power Cord Revelation
Mootsdude, here is a follow up with more details... Audio Grade Power Cords - AGPC We investigated this interesting problem years ago and found that the power cord(s) affect the 'ground-floor' noise of the audio equipment being used. The question... 
Why does better power = better sound?
Bryon, Audio Grade Power Cords - AGPC We investigated this interesting problem years ago and found that the power cord(s) affect the 'ground-floor' noise of the audio equipment being used. The question is then how ? By trying different home made p... 
Risk using amp Wattage than speaker rating?
Rtrauthwein, The wattage rating is the maximum wattage a speaker can handle before they burn out,and has nothing to do with the Fidelity limit per wattage limit! 30 watts rms is all that most speakers can handle without causing distortion to the a... 
Anyone have experience with "burn-in generators"?
Ed Ekurilla, We were asked to test some cable burn-in processes a few years back and it was interesting to see the various ideas about cable burn-in. Square-waves, slow triangle rise-fall time, random noise pattern to sinsodial waveforms were seen... 
Pure silver wire: solid, stranded or Litz wire?
Aber23, Silver has some unique sound properties, but seems fromall of the reports from many users silver tends to be bright. Litz wire all silver. A true litz wire, all strands isolated from each other is rare. Modified Litz wire has a sharper fre... 
Room treatments - GIK Vs Acoustimac
Milpai Please no on GIK and triple no on Acoustimac - panels. GIK large and bulky costly not so hot on acoustic waves control... Acoustimac NO NO NO ... heavy dirty-crumbly costly and poor aucoustics. We are very sorry we used these items. Heavy... 
Do Cable Makers Know Their Own Products?
NO... not because they do not know the flavor of their cable,it is that the cross-overs in use and the speaker elementschange - hid what the cable could-should sound like. Until we stop using cross-overs, the cable confusion willcontinue to be an ...

Power Cord Revelation
We, as posted before, investigated this problem and were amazed that power cords made a difference. We used a network analyzer to check power cordsfor the low end testing of common L,C,R measurementsare of little value as we found out. Our first ... 
Power Cord Revelation
We investigated this interesting problemyears ago and found that the power cord(s) affectthe 'ground-floor' noise of the equipment. SWR has been over-looked as the culprit, due to the length of the cord being 'too-short'. None the lessthe power co... 
Laying it on the line
Thanks for your POST...We walked away from 11 years of researchfor just the same reasons you touched on.Our reserach was - is ahead of the crowd, butis not well recieved, yet. Cable design was our first project, which soonpointed out that the audi... 
Cheap tweaks...What would YOU reccomend?
Not easy to do but: take out your cross-over circuits and raplce them with over-lap circuits. [ any circuit that does not have a cross-over point ]
