Everything makes a difference...
S Clark:
I picked up two pairs of Wywires RCA interconnects a few days ago. I haven't really had a chance to listen to them today, but I've got a friend coming over tomorrow, bringing some Audioquest IC's so I needed to get cracking.
My wife is out of town, so lots of things are possible. I started with a really nice LP, Jennifer Warnes "The Hunter". Just threw it on the table, kept my old IC's in, no diffusion in place, coffee table in front of leather couch... nothing optimized, and it sounded like it. My line sources can overpower the room easily, and the song "Way Down Deep" just did its boomy thing at about 120Hz.
So I put the diffusor panels in place in front of the big screen, and a second pair forming forward wings outside the speakers. Things improved. Moved the coffee table, things improved. Changed to the new/used Wywires silvers, things improved. Moved the couch back to open some space, switched to classical. Hi Q recording of Rimsky Korsakov Capriccio Espagnol. Took out the leather couch, moved in a cloth covered love seat. Things improved. More space, more detail. Changing the seating furniture is clearly an improvement.
Next turned out the lights, and poured myself a hot cup of coffee. Don't know if the music was better, but I enjoyed it more.

How often have I said these things?
Everything effects (affects) everything...
The room is the most important interconnect in the system...
Oh, yeah: power is the heart of the system that helps the brain work.
Just sayin'.

Interesting you should mention Jennifer Warnes The Hunter. I use a few tracks on that when I need to get into “reviewer” mode when I’ve made some changes. It’s good to hear you got some good results making some simple changes. Acoustic panels are next after I’m done with resonance control...
S Clark:
The Hunter has been a standard for evaluation since Danny Richie introduced me to it in the early 2000's. But I just got the vinyl a year or so ago- it's got some sounds that the digital is missing. I keep acoustic panels behind the speakers full time... 6 inches of Corning 703 covered by a Persian rug. The diffraction goes up and down.
And Dave, I knew I was quoting you when I typed it... :thumb:

I had a professor in engineering school who. Used a water spigot as a paradigm for the operation of a transistor or a triode. He said imagine a water valve whose flow was controlled by some sort of low water pressure. If that low pressure opened and closed the valve then the output flow would be exactly analogous to the input pressure except it would be boosted to a higher pressure that would be dependent on the pressure being delivered to the house by the city water department. This is exactly the same as a small voltage signal applied to the base of a transistor controlling the flow of the higher voltage between the collector and the emitter. (Highly simplified but it makes the point.)
He then went back to thewater flow example and said however, it is easy to see that you will only get a perfect replica at higher pressure if the pressure from the city water department is perfectly stable, because if there are any fluctuations in the city water pressure then the output flow would be a combination of the valve fluctuations drive by the input plus any fluctuations in the city water pressure and therefore the output pressure would never be a prefect analogy of the input with gain.
He then went back to electricity and said this is why power supply design is so important, because any deviations from pure dc in your amplifier design will ultimately find there way into your output as distortion.
I think we all know now that even good power supplies can do just so much and anything we can do to give them cleaner power to start with can only improve their operation and that of our systems as a whole.
That professor was Dr Edward Kaffreson and he was by far the best engineering teacher I ever had. His goal was not to get you the blindly crank out math equations the produced the “right” answer, but rather he was always more concerned the you understood how and why a circuit I did what it did. He was happier to hear you explain some in English than to see you prove it mathematically. Took every class I could with him.
The only other teacher I had that came close to him was a lab teacher by the name of Val Sanford who had just retired from Grumman as the Chief Test Engineer for the Lunar Module program. Val used to yell at us when we tried to run equations in the lab. He used to say “You can let the PhD professors teach you how to solve textbook problems, let me teach you how to be a real engineer. If we took did 30 minutes of math to size every resistor in the Apollo program we wouldn’t have made it to the moon until the year 2525.” One of my most exciting moments at NYIT was when I got into Val’s Control System labs. Who better to teach you about control system than the Chief Test Engineer for the Lunar Module? It was a great class.
