Cable vs. Electronics: biggest bang for the buck

Audioengr is there a difference in sound between Auricaps and Black Gate? Do Caddocks sound the same as Vishays?

Bwhite, whatever component, including cables, that gets out of the way of the original musical performance through reduced distortion of the signal can offer the "biggest bang for the buck." If, for instance, your electronic components which cost ten times that of your cables are flawed in some obvious way, no $300 cable will come to their rescue. In fact, a good cable, regardless of price, will only reveal other problems upstream. Obviously, a $300 component would be incapable of "revolutionizing" a system. I would agree, however, that if your electronics are fundamentally sound, a properly designed $300 cable can make a remarkable improvement, given that your previous cables were not properly designed.

I happen to believe that all modules, including gain can effect sound, even if only in a less obvious way. For instance, the choice of a pot for controlling levels can effect the sound.

The best bang for the buck in one part of my system cost almost nothing. I own a Linn Sondek LP12 turntable, with ITTOK arm and an older Kiseki Blue cartridge. Years ago, I tapped on the arm until I found the point of greatest resonance, and wrapped a short lightweight piece of clear rubberized tape around that point. The improvement was remarkable for the cost of about 2 cents.

While I no longer have the Adcom GFA-555 amp, a few years ago, a friend of mine who hand-makes cable, suggested that I try to replace a few of the wires within the amp with some of his wire. This Adcom, I should add, was already modified and markedly improved by Stan Warren of PS Audio fame. After a short burn-in period, the improvements from inserting the new wire were immediate and confirmed by other audiophile friends who were not told of the change. Yes, one of the changes was in the tone, but it was the least obvious improvement in this tweak. The frequency extremes gained greater extension. Whenever the original signal is allowed to pass unhindered, some increase in a particular frequency will shift the overall tonal balance. The greatest improvements were that the sound became quicker, with greater dynamics and weight. Clarity improved as well, and there was a decrease in audible noise. All of this came from changing a few inches of wire in critical areas of the amplifier. I should also add that the original Adcom wire was of the standard copper stranded variety, not as short as possible, and was hanging over the main circuit board. This probably contributed to the noise I spoke of. We used solid core silver wire in the shortest possible lengths and situated them out of the path of the circuits.

Hshapiro - for the most part it looks as if we are on the same page.

The topic of this thread is "cables vs. electronics: biggest bang for the buck". I used a $300 cable vs. a $300 component as a comparison and it seems you agree that a $300 component wouldn't revolutionize a system like a cable might. How about a $1500 cable vs. a $1500 component?

So if a cable is good, it reveals problems? Not in my experience. What defines a "good cable"? Problems? That's weird. Good cables tend to be good no matter where they are. If a cable reveals a problem upstream - wouldn't you think that just maybe the cable isn't the best choice for the application? Or do you fall in the camp of folks who try to change components to accomodate what they perceive as a good cable?

Tell me if I am wrong but I think the potentiometer is in the signal path. It's not truly the "Gain Stage". But I know what you mean.

I am glad you agree that the various modules can change the sound of a compoenent. However...

Everything you experienced in the changes to the Adcom can be associated with tone and are perceived because of the change in tone or accentuation of various frequencies which were otherwise subdued. Greater Extension, Dynamics, weight, clarity, speed, decrease in noise, etc. This is tone at work.

Dynamic: Giving an impression of wide dynamic range; punchy. This is related to system speed as well as to volume contrast.

---> Made evident by a change in tone.

If you've ever thought of cables as tone controls you should try high end NBS cables... Man! They can produce some very dynamic music!

Weight: The feeling of solidity and foundation contributed to music by extended, natural bass reproduction.

Clarity? How about Transparency?

Transparency: A quality of sound reproduction that gives the impression of listening through the system to the original sounds, rather than to a pair of loudspeakers. 2) Freedom from veiling, texturing, or any other quality which tends to obscure the signal. A quality of crystalline clarity.

Highs.... Open up the sound create that illusion of clarity.

Let me give some examples, since I have some technical knowledge in this area:

1) Film resistors - these are lower inductance and lower noise. They reduce the thermal noise that causes the hiss at low levels that you hear. Does not affect tone.

2) Poly caps (polypropylene, polystyrene) in the signal path - these reduce dielectric absorption. DA causes time smearing of the signal. also does not affect tone. This is a dynamic effect.

3) Power supply cap increase - this provides more capacity to respond to high-power events, so dynamics can be improved. prevents voltage sags when high-power events occur. does not affect tone. This is a dynamic effect.

4) high-frequency, low internal resistance caps in the power supply (decoupling caps) - Improves response to high-frequency transients. Prevents truncation of transients because the power system can react faster. This is a dynamic effect.

Changes in tone are changes in amplitude as a function of frequency. It is a steady-state effect.

As for my system, I have 3, so I will describe my reference:

Source: Sony DVP-S7700 transport
Pre: Proceed AVP
Amp: Coda 10.5
Spkrs: KEF reference 104/2
Cables: Empirical Audio

This shows that old components, particularly speakers can still be reference quality. Also, you can get 95% of the performance of the most expensive reference components at a fraction of the price.

Audioengr is there a difference in sound between Auricaps and Black Gate?

Do not know. Probably dependent on the application. If there is, it is a difference in internal resistance or dielectric absorption. Neither affects "tone".

Do Caddocks sound the same as Vishays?

Do not know. Probably dependent on the application. If they do not, it is because they differ in thermal noise or inductance.
