Gain / Amplification
Lower gain in amp and higher gain in pre could be better for two reasons: - It moves more gain to electrically quieter environment (pre) - It reduces relative electrical noise pickup by interconnect. Of course it depends how power amp reduces th... 
Digital source upgrade suggestion?
My setup is pretty much the same.  The beauty of it (WiFi) is that nothing on computer side matters (Computer speed, power supply, amount of memory, playback program etc), since there is no direct connection and no real time clock .  Airport recei... 
Analogue v. Digital...again (Washington Post)
 
Grounding questions
Hum independent of volume can be a sign of old/dry power supply caps. I would, per maxwave advise, take it to a friend and try it there. Also, since you have balanced connection between pre and amp, check where shield is connected on both ends. I... 
Optical Isolation
@navyachts Jitter converts to added noise proportional to signal level (no noise without music), detectable only as a loss of clarity.  The best way to compare two streamers, network players or digital cables is to listen, paying attention to clar... 
Optical Isolation
Technically coax should be better, since transitions are faster, hence system noise (jagged edges on transitions slopes) does not convert to timing jitter, but coax is prone to reflections on characteristic impedance boundaries (that adds/changes ... 
May The Gas Be With You
@czarivey You need Flamenco guitar - poor Presence, huge Projection, short Sustain  
May The Gas Be With You
The biggest crime are the guys who collect them and DON"T EVEN PLAY! Why? Should people who collect China use it?  What about guys who collect knives?  :) Collecting is different from upgrading. GAS starts from "Gardener's Syndrome" - constant... 
Suggestions for a digital cable.
@soix   Yes 1.5m is minimum to avoid reflections. It is assumed that cable is not perfectly impedance matched, causing reflection of the signal on impedance boundary.  The dangerous one is the first reflection from the end of the cable.  If cable ... 
Whole House Surge Protection…recommendations!
When you get direct (or nearby) hit nothing will help, but I would still use protection for smaller events and of course unplugging.  I installed in Siemens style panel two 65kA Siemens "BoltShield" QSPD2A065P protectors ($126 each st Amazon).  I ... 
Condolenances to The Siau Family
John Siau, I'm sorry for your loss.  
What's better, one conductor or two conductors for an RCA interconnect?
@jumia   At one RCA connector shield and negative/return wire are both soldered at the base of the connector while signal/positive wire is soldered to center pin.  On the other side only two wires are soldered while shield is left unconnected/floa... 
Billie or Ella? Maria or Renata? Technique or feeling?
kijanki -- I actually saw Jimmy Scott perform live, probably at Dante's in Hollywood. A real treat! That would be my dream.  Unfortunately, he passed away. In 1967 my brother had 2 inexpensive tickets for Rolling Stones concert.  I declined an... 
Billie or Ella? Maria or Renata? Technique or feeling?
Sarah or Ella?  At first I like Sarah more for more interesting way of singing - vocalizing, suspending timing etc., but at the end Ella won me over with her immaculate timing and swing (discipline).  It is all matter of acquired taste, for instan... 
What's better, one conductor or two conductors for an RCA interconnect?
@atmasphere AFAIK we should write symbols of units named after person with capital unit letter V, kV, A, kA, kHz, kW etc. but spelled out units with lowercase : volts, amperes, ohms, watts.  Multiplier doesn't change that, so it will be kilovolts,...
