Synergistic Red Fuse ...

Hello Dave,
Thanks for sharing your insight and observations based on various products in your system. What has struck me is that these various system tweaks/accessories have a very prominent accumulative positive effect. In my personal case, premium  fuses and AC wall outlets, component stands for vibration management (Star Sound), upgrading capacitors (Duelund and Jupiter) and component grounding (via the Tripoint Troy) all= superior musical sound quality . I’m sure there’s is some good fortune/luck factor involved but the end result has been immense satisfaction and frequent (and long) listening sessions. Tube selection/rolling has been fun and certainly rewarding. 

Once you have determined that you’re very happy with your components and speakers for the long term, these audio accessories/tweaks help extract their full sonic potential.

Exactly Charles. Understanding this in its entirety is fundamental to good purchasing decisions, regardless of where one is along the journey.

Best to you Charles,
Dave

His [the reviewer's] finding the source components more demonstrative of the Black fuse than the power amplifier matches my outcome. No doubt that this is very likely brand and/or component dependent.

I suspect a relevant factor is that both you and the reviewer use amps that are biased in class A, since both amps are SETs, and therefore the amount of current drawn through their mains fuses remains essentially constant and independent of the dynamics of the music.  It might be a different story with amps that are biased in class AB most or all of the time, and especially in the case of class D amps, where the AC current draw fluctuates dramatically with the dynamics of the music.  Which would result in rapid fluctuations in the resistance and perhaps other parameters of the mains fuse.

Also, the generally much higher current ratings of fuses that are used in power amps and integrated amps, relative to those used in upstream components, and perhaps differences in designer preferences with respect to how much margin is provided between fuse ratings and actual current draws, could conceivably be factors that are involved.  I note that both the reviewer's amp and yours are made by Coincident.

As you said, "no doubt that this is very likely brand and/or component dependent."

Hi Al,

Another supremely intelligent yet content-disciplined post. I honestly don’t know what we would do without you and your wisdom.

Best to you Al,
Dave

Hello Al,
As with Dave I always appreciate your insightful and well reasoned contributions. Funny thing is that my Coincident Line Stage and each mono block SET use a 3 amp slo blo fuse.  My Line Stage is one of the very early models of the  first year (2009). The current ones use a 1 amp slo blo fuse. I'd describe the mono blocks as having  "noticeable" improvement but in the subtle range . The DAC and Line Stage reveal considerable improvement that's immediately recognizable. 

Al, although you aren't a user of the upgrade fuse products as many on this thread obviously are I greatly appreciate your intelligence and very mature decorum.  You effectively demonstrate that forum  contributors can disagree and express opposing opinion/perspective without gratuitous insults and childish put down summation. No doubt that others recognize your consistent mature manner.
