High current power cables
More space between the conductors (Live, Neutral and ground) the lower the noise floor Radiated or induced electrical noise is proportional to area between wires,  To lower electrical noise pickup Live and Neutral should be as close as possible... 
After years of separates, I'm going integrated. Anyone else do the same?
I like idea of separates for few reasons - it is easier and cheaper to upgrade just one component - it is easier to repair one component. - In case of damage beyond repair no need to replace everything - Separate preamp or DAC allows to move signa... 
Is it me, or others?
He was likely confused with word "Tuner".  Many years ago I was planning to air travel with "Infrared Head".  It was basically large metal cylinder with lens on one side and "+, -"  connectors on the other. It is used to measure objects temperatur... 
whole house surge protector
The issue might be inductive reactance.  Inductance is likely in order of 300nH/ft.  It is not a lot but even the smallest reactance with thousands of amperes clamped (my Boltshields are rated 60kA each) will produce big voltage drop.  Sensitive c... 
whole house surge protector
I installed in Siemens electrical panel two Siemens 60kA BoltShield protectors.  They are in the form of dual circuit breaker and just plug-in into empty spaces in the panel.   You can as well install Siemens FS140 that will work with any panel.  ... 
Will I benefit from a subwoofer with 20Hz speakers?
Assuming 18ft between front and back wall your room will amplify 1125/36=31.25Hz and multiples (62.5Hz, 93.75, 125Hz etc.).  31.25Hz is alway welcome, but multiples require room treatments.  
Sound Better w/Amp Directly Into Wall Then Thru Zero Surge
Amps with Linear Power Supply draw current from the mains in short narrow spikes of very high amplitude.  Such current spikes cause larger voltage drop than expected.   It can limit maximum output peaks reducing dynamics.  For less than maximum pe... 
DIY Digital cable question
I would connect outer shield to ground at the source (transport) side only.  
Is EMI noise in electrical system inaudible?
@jumia . If you mean harmonic distortion it is a deviation from original shape of the signal.  
Is EMI noise in electrical system inaudible?
There are many ways high frequency interference can become audible. One way is simply modulation. Two inaudible. signals mixed on non-linear element, like semiconductor junction, will produce new frequencies, that might be audible. The phenomena c... 
Conditioner vs. Surge protector
I second Mapman's recommendation for Siemens BoltShield.  I installed two of them since I had two free spaces on each side of Siemens Panel.  Total of 60kA x 2 = 120kA.  In addition I plan to add Siemens QSA2020SPD. (about $80) replacing two circu... 
Do you trust your system?
It is hard to make A-B comparison with life concert, especially when best seats are not available.  We assume that sound of instruments we hear thru our system is true and later compare everything to it.  If I have warm sounding system (added even... 
CD transports; do they really matter
it might not make big difference with DACs that offer strong jitter suppression, like my Benchmark DAC3 (with Asynchronous Rate Converter), but will make some difference with most DACs.  Higher end transports tend to have higher slew rate of digit... 
How does solo piano help you evaluate audio gear?
@mahgister  Thank you.   I read this while ago in Wikipedia.  The title was Piano Tuning.   Opinion about sounding "like out of tune" was expressed by John Siau - technical director of Benchmark. It becomes really strange when it comes to digital... 
How does solo piano help you evaluate audio gear?
Piano has stretched overtones.   I believe it is somehow related to the fact that string has mass.  Extremely long and thin string under extremely high tension would have straight harmonics, but it is not practical.  Because of this stretching pia...
