I read both links. The first is common knowledge and nothing about RF. The second is long so if there is something in particular you want to me to read please quote it here. Are we playing "Wack A Mole’ here?For the What’s Best forum, just look at JCarr’s posts. No whack a mole- not even sure what that comment is even supposed to mean.
Im really tired of RF being the devil for everything. Usually if there is RF sensitivity you will hear an AM radio station. If there aint no radio coming in there aint no RF. Lets get real please.
No-one has said RF is the devil for everything except you, just right now. But these two links did point at RFI (or ultrasonic or near ultrasonics, in the case of MM cartridges) being a problem with LOMC cartridge operation... I don’t see how that can be construed as ’everything’.
Ralph has not honored the stated purpose and rather come here to once again to hawk his paradigms and unusual ideas about cartridge loading and RFI. You are into vinyl I see. Do you agree with his loading suggestons? Dont we load a cartridge to change its sound? That last one about loading a cartridge for the sake of the preamp was so out of the world. Most of just a juse a ferrite bead to stop RF from coming in.This statement is outlandish and false. Please note though that I am not attacking you, just the veracity of this statement, unlike you who sees fit to attack me personally. I have honored the stated purpose, as I am a designer of amps and my door is open.
If you say you looked at both links and came away with the idea that RFI has nothing to do with it, the only conclusion that can be drawn is that you didn’t in fact read the links or failed to comprehend their significance. When we are talking about noise in the MHz range, that’s RFI, especially when it is the result of excitation of a tank circuit.
I do agree, Ralph should have never entered this thread nor should you. I dont see a question and I dont see a contribution. You left, said you wouldnt come back, but you did.Roger, you seem to appreciate my being courteous when I offer corrections (which you seem unwilling to accept), but you seem unwilling to be civil in return.
Contrary to yours and others impressions, this is not your thread- its a public forum.
As a bit of a hint, I find that keeping decorum in spite of personal attacks (including outright untruths) is a simple tool to maintain credibility. FWIW I have an EE just like you and I don’t engage in pseudo science any more than you. I can prove everything I say. I suspect that you are not *as* acquainted with equipment from the old days- 1960s and before, as I might be. You have said that my talk about the Power Paradigm and the Voltage Paradigm is the pseudo science to which you refer; to me that just suggests that you don’t have a grounding in history. This despite my showing an example of what I was talking about (one that we have discussed prior); in spite of that evidence (the Fisher A-55 I linked, and any amplifier with a ’damping’ control) right in front of your face, yet you still accuse me of pseudo science!
You are getting out of hand here. This entire thread is in violation of Audiogon posting rules, for the simple fact that you primarily use it for promotion.
On occasion I get accused of the very same thing, but those that do so will note that I have yet to start a single thread on this site (despite being active on it since its inception in the 1990s), let alone one that focuses primarily how great I am in tandem with how great my products are, all the while demeaning (in some cases, falsely) others. I do mention my products when asked and also in the context of related questions (such as balanced operation; quite often because there is much misunderstanding about how balanced lines are supposed to work).
This is not your thread! - if that were the case it would be on your website. Instead you are posting on a forum that is open to the public. My presence here has mostly been to keep the record straight when things have gone off the rails. The 6SN7 thing and the cartridge thing are two examples.
I can see that it bothers you as much as it does me when you see things that are untrue. If I can offer a bit of advice:We often go thru live with made up stories. In fact we live as if those stories are true. When life and the stories don’t agree we suffer. At that point, to end the suffering the best thing to do is drop the made up story. You will note that I do not attack the voltage rules as being made up. I regard them as an engineering solution, but one that has some bad applications. I’ve pointed out why earlier and don’t need to repeat myself. The old power rules are one way out of the resulting colorations of the voltage rules, but they come with their own price (limited market, for one, more fiddling and more careful equipment matching for another).
IOW, if you think I made up the idea of the power rules, you are simply not grounded in history.
I am perfectly happy to have that conversation on a different thread. I’ve been having this conversation for the better part of 30 years and its not been debunked by any engineer that listens- only those who don’t and are further unaware of how the voltage rules were developed.
I dont mind any designer coming here if we both understand electrical science in its accepted current form and speak the proper language. If you want to read made up science there are pleanty of other threads on here for that.I got my degree at the UofM. I don’t subscribe to anything made up. Enough with the innuendo already- if you don’t get what I’m talking about, just say so, otherwise lay off. John Curl got it, Nelson Pass got it, other engineers on this site got it...
I have a a question for Ralph, Why have you not sent an amplifier to Stereophile for review? They have reviewed all of mine and preamps too.
We sent a preamp to TAS for review. It did quite well- the reviewer bought it and said so in the review. Then he moved over to Stereophile prior to the publication of the review; it got published there. At that point we knew we were in trouble when we got the news that he had jumped ship to Stereophile, as we had been warned by people from several companies (ARC among them) that if you can’t afford advertising with them, they will treat you as a sacrificial lamb to show how hard hitting their reporting is. Sure enough, some months after the initial review was printed (in which I had to challenge JA’s measurement comments, as the Audio Precision at that time didn’t properly support a balanced input, despite it appearing so- a different conversation), and after being asked if we would advertise in the magazine, the reviewer was later instructed by Stereophile editors to print a followup. Apparently when he was installing defecting tubes in the preamp, it didn’t work right. We tested several of those tubes; one was a Telefunken that was so dead that I thought my tester was at fault as it got no reading at all when the Telefunken was lit up. I had to test some known good tubes to know that I was not going nuts! To date I’ve yet to see another 12AT7 that bad that still had a vacuum. We got blamed in the followup for that failing on the part of the preamp. Do you have amps and preamps that function correctly on bad tubes?
A second product, the MA-2, was destined for a nice review in 2004 by Paul Bolin when he was with Stereophile, but a company that was trying to take over my company threatened Stereophile with a lawsuit if they didn’t give the amp back to them. Paul let me know this was happening, and since we owned that amp I went and picked it up. While the lawsuit never went down, JA was sufficiently rattled by that event that he removed Paul from the Stereophile staff.
