In Reply to: Re: Low DCR I felt the same way but... posted by drlowmu on April 20, 2007 at 19:22:47:
Jeff, my response was not aimed at you. I meant what I said, which was that IMHO with a big enough reservoir cap and no great variation in current demand, voltage sag shouldn't be a problem. Now, that is not to say that a reservoir cap solves all problems for class A. I'm not saying there's no point in refining the PS to make it sound better. Nobody wants to listed to HF noise, mains-borne inductive spikes, SS diode hash, poor quality electrolytics or any other undesirable effects that can be caused by a PS that's not doing its job very well.Once you have current demand that can vary, then you need a stiffer PS to avoid the dreaded sag (which may be loved by some guitar players but not by HiFi enthusiasts). Obviously, you're not going to achieve this with a PS with high DCR unless you use active regulation, which most people would rather avoid.
Follow Ups:
The good veterinarian has fixated on Low DCR as a prerequisite cure-all. It's a preemptive strike against noise, poor dynamics, narrow soundstage, lifeless amps, etc. etc. With apparently no legitimate evidence whatsoever, not even valid testing, he is not only intent on converting the world to his view, but on taking credit for this nonexistent invention. You will have to be satisfied with warning others. I predict common sense will continue to elude this individual.
URL below.T_K gets VERY quiet when we ask for HIS credentials.
T_K reminds me somewhat of the anger of the late Mr. Cho.
T_K does not speak to us - of his credentials.
Properly introduce yourself. "Question Mark" all over again ??
Jeff
That post makes me ANGRY!"T_K gets VERY quiet when we ask for HIS credentials."
Are you using the royal 'we' or do you actually imagine that other people besides yourself feel the need to know? If you do, then I think you're seriously mistaken."T_K reminds me somewhat of the anger of the late Mr. Cho."
How DARE you compare someone on this forum to a mass muderer with a psychopathically antisocial personality, just because they hold different views to your own? This is rudeness in the extreme, and a sign of your own inadequacies.
credentials are earned, and given around here. Not kept by the people they're referencing.
All my stuff is posted on Inmate Asylum, my systems, etc. And Ty, if you have hung around here for several years, I've very openly discussed my DIY audio projects and ideas.Prior amps of mine were pictured in 1984 (?) in Sound Practices magazine, a very nice P-P A1 Type 250 amp and a complex P-P A1 6B4G amp. A triode line stage schematic of mine, at 600 ohms, was also published by Joe Roberts.
The same has not yet been said for "whoever" Triode_Kingdom is. He is an unknown, except that he can spell, access the Forum, and post nasty thoughts up here.
So, if he wants to on-Forum attack Jeff's every post, its fair for ME to ask him to post his audio credentials. I have earned mine over 40 active years in the hi fidelity hobby Ty. He has not come forth with his..... and he won't.
I think you missed it. Those credentials are those you claim. They are not what I defined as legit. I suggest you re-read how I defined them.If you have made some breakthrough, I am sure it would spread much faster if you didn't get in the way of people who are trying to discuss it. It doesn't matter much if they're speaking positively or negatively. If you have indeed discovered something, get out of the way, it will spread if it is real. It also helps if the effect can be quantified, adjusted and explained.
Judging the response to your descriptions, I don't think you're getting very far. You may even go backwards.
Ty,There ARE people who implemented the low HY, C, DCR supply idea of Dennis'.... which I made public on Forum in 2006, and have reported positive,....actually, very positive results on Forum.
As for "lately", I just posted this information on 10 gauge / 30 gauge internal bi-wiring last week.
Give it some time, and DIYers will no-doubt, implement it, some will. It certainly is very demonstratable as the basic technique exists - optimized in all the Serious Stereo components, and, at a lower level due to my budgeting constraints, in my modded Eico HF81. I have the piece available for others to compare it - to a stock unit.
There's no 'but' that's going to work here. You've presented the idea, now get the hell out of the discussion unless somebody calls you back into it. Then get the hell back out of it afterwards.Or do you enjoy this counterproductive arguements that crop up everytime you share your most recent revelation?
