Reasonable high end interconnects: without breaking the bank
@cleeds There is value in better cables that are well mated to a system.McManus gave no inkling as to manner of improvement, but just that he had scored savings purchasing used. Did he audition anything or just grab a deal? What specific problem w... 
Reasonable high end interconnects: without breaking the bank
Someone finally got me to try better cables and my sound quality jumped. It jumped again when I spent $500 on used $1,200 cables and jumped again at $900 for used $2,200 cablesActually, "Someone finally got me to try different cables and my sound ...

I just turn it up moreFor decades cognoscenti have played material at optimum level for the system and the material.It's one reason recording studio control rooms are so well sound proofed.Adjusting levels to compensate for ambient noise often com...

The amps mentioned sound like PA amps which are not designed for HiFi home use.Any system that is audible when not playing isn't HiFi.There are many sound apps available for smart phones. Broadband, ambient noise should be below 40db or below 30db...

Ya shoulda PM'd me back in the 70's. Mine was dead quiet ;-)

85°C caps rated for 2000h in an amp running @ 35°C [95°F] have an rated life of 8000h.Oops. 2^5 = 32. 2000h rated are 64,000h @ 35°C. 32k days @ 2h/d ≈ 88y.However other factors limit the life other than temperature, so 15y is a safe limit.

Wow, excellent information. I was mistaken, I had 105’s installed. Could you clarify your last sentence? Thanks!Installing 105°C caps is usually only a cost issue unless one takes the time to evaluate all parameters.Old electrolytic caps increase ...

I have 80's NAD ampsElectrolytic capacitors have an industry rated life of about 15 years. Anything beyond that is borrowed time, running or not.Capacitor temperature ratings are 65°C, 85°C, 105°C & 125°CCaps are rated for about x000 hours @ t...

AC Infinity fan unitOne purchaser mentioned it is quite audible at anything above a 1.This device will pull air through the amp and likely build up dust in the bottom vents.What is desired is to pull a small amount of air around and away from the ...

Help with crossover capacitors
Chaps,When you parallel caps and resistors, you also change the inductance, which may or may not affect the sound depending on the rest of the circuit.danybad:I would remove the shelving control and associated resistors to make the system flat , g...

jworth:A recent AQ audio left me severely nonplussed. System was all McIntosh driving Bi-Wired B&W 800 D3. Generally excellent, with all AQ cables.Switching the speaker cable to a higher priced $12k vs $6k destroyed the balance. Vocals became ... 
High end Cables not important for certain electronics?
As a former professional recording engineer, I can attest that cable is every bit as variable on balanced connections as unbalanced.In some situations, cables make next to zero difference and others, large.The only constant is YMMV

All of the above are worthless because no one has your gear in your room with your source material and your preferences.The outputs, cables and inputs are a complex impedance. They interact, so without identical parameters, recommendations are wor...
