Measurements are a way of verifying/calibrating. What matters to me (if judging sound quality) is listening - but with my ears, not with my eyes or biases. What matters to you might be something entirely different.
Then start a new thread saying that and leave this one alone.
I can't see how Julf is that objective- he owns Isobariks!
I never claim they are the peak of transparency or neutrality, or "better" in any absolute sense - I simply recognize that I like them, sonic warts and all. And when coupled with active filtering and EQ, and driven with high-current, high-damping-factor amps, they are actually somewhat better than their reputation (as long as you accept the tradeoffs of indirect sound).
I think you need to do a few tweaks to those Isobariks Julf a few Teflon caps, a bit of platinum wire, solid kryptonite binding posts (to keep those pesky Supermen away).......... go on you know you want to
Hmm... yes... And some chrome exhaust pipes and furry dice...
I would always caution anyone against the 'modification' of a piece of electronics unless they know at least as much as the engineer that designed it.
I'd be interested to hear them Julf- I've only ever heard them 'back in the day' with contempory Naim stuff. Kind of like a cross between hi-fi and a good PA system. Diffuse stereo but solid and punchy. I'm veering completely OT though, sorry folks.
I really wish Hypex had just had some custom sized polypropylene caps built for these modules...
I would love to see a graph mapping dielectric constant to sound quality.
As I read the articles, lower dielectric constant directly relates to lower dissipation factor and dielectric absorption and to better sound quality.
No direct graph, but pretty strong evidence.
Hmmm: lower dielectric constant sounds better.
Dielectric constant tells the amount of loss of the signal into the dielectric (and subsequent delayed release, the memory effect). This is the science, not speculation.
So, we have actual technical specifications (measured) which show the DA of various types of caps, and we have a technical explanation of why higher DA would result in signal loss
If you say so.Science tells a higher dielectric constant means a higher amount of loss into the dielectric. Any extrapolations from that into audible effects is speculation.In an attenuating circuit, the higher resistance of a resistor corresponds to higher loss. Does that imply that lower resistance values sound better per se?Actually, yes. Ask any good analog circuit designer about this. If it is possible to use less R, it is better, even just from a noise perspective.
