Wrapping power cords and interconnects with copper foil.
@joelepo @richardbrand  Unfortunately this is not a group about engineering or physics most people here seem to be interested in the hobby more than the engineering principles. Sad people who love listening to music so much have such low regard fo... 
Wrapping power cords and interconnects with copper foil.
Audiophiles use very good equipment and use at least good cables. It is strange that very expensive power cables aren't FCC tested and often not UL listed. RF in cables hasn't been a problem in many years. I think your equipment is properly design... 
??? Full Loom vs Mix ???
Your equipment isn't made with the same internal cables, even if you use the same equipment brand.  Your equipment may not have cables at all internally, sone very high end equipment commonly has only PC traces.  There are different loads all e... 
DAC shopping - Trying to sift through the Hype. Can I trust the reviews these days ??
The Harmony DAC is a real surprise, fights way above its weight only negative is it's a little not tube sounding. Also the biggest change in audio quality to me hasn't been cables or components but the switch to the Is2 connection much better than... 
PS Audio BHK signature preamp
I've owned all the BHK line from PS Audio and love the sound the only thing is I have very efficient speakers 96db and the BHK equipment isn't the quietest so the noise was making me crazy. I replaced my BHK preamp with a Boulder preamp that was 4... 
Solid State Preamp to replace tube unit
Some things in life you can't have, one of those things is tube sound on a SS component. The answer is AI / DSP wait just a little while and you will be able to tune you system into your perfect warm perfection.   
Recommendations for a jazz record which demonstrates vinyl superiority over digital
There is no record player that has as good of a signal to noise ratio as a good digital recording. Yes there is warm distortion and rumble but records are not in the same category as digital when it comes to accuracy.   
Retirement System Finally Completed: Impression of the Mola Mola Tambaqui
Congratulations! I was a professional sound engineer for 40 years then I got into audiophile equipment and it wasn't what I thought. It wasn't about accuracy like everyone says because audiophile systems don't sound like professional systems, (I h... 
Room with glass windows as a walls.
Many years ago the acoustics company I worked for was the 4th company to try to put in a sound system in the newly built Crystal Cathedral in So. California. Clearly it was an impossible job and our Lead engineer said they would have to put in sat... 
Upgrade speakers or DAC
You have made a big mistake not having better speakers all along, your system is like having a 500 hp engine and exhaust through a ½ inch pipe.    
Best streamer, don't want Roon, don't want a screen, A DAC is OK but not necessary
@philgo01 This is a tough place for EEs. In a digital circuit the great part is the perfect handshake to the next component it's easy to get a 1 or a 0 right that's the glory of digital in a nutshell. Analogue is a really tough signal to get right... 
Audio Cables: All the Same?
It is very simple to see the difference cables make, simply do a frequency / amplitude and noise test with the old cable and with the new cable the difference is the difference. These aren't magical impressions that aren't measurable, audio is ver... 
You're not a true audiophile unless...
I have more than 1M of sound equipment but I don't want to be called an audiophile  because I've come to find out being and "audiophile" means you have to believe in things that are not true. It's more than a hobby it's like a cult. I'm sad to say.   
Vibration Control
In General solid state circuits are not effected by acoustic vibration. The exception is in cheeper ceramic capacitors they can be effected by hi frequency vibration and the dielectric layers separate.  One of the highest vibration environments w...
