By technics assuming the EPC series with their cvd boron tubes (so horribly high tech compared to hewn by virgins and hand assembled by trolls). I know why the Be Shure used can't be made anymore, but you would have thought one of the high end cart brigade would be trying to replicate the sort of lightness and precision of 35 years ago. especially given what the loony fringe will pay for a cartridge!
 
There are very find MC cartridges out there. From my experience, the more expensive ones sound better than the cheaper ones. This is my actual experience, not some hope for the cost effective manufacturer making an amazing phono cartridge. Even the MC cartridge that I am now using is a disappointment. I will change it with something better from the same importer, sooner or later. My previous cartridge from the same importer WAS sonically better, and I miss it. Why this is so, I do not know, but it is NOT just frequency response.

Thanks Bill, I too, got it wrong. So what? It is meaningless quibbling.
Now, if you guys wanted to learn what vinyl reproduction can really do, you would graduate from MM to MC, and expensive ones too, along with comparable vinyl playback equipment. Nobody has shown me this, so far. No wonder you guys like CD's! '-)
I've been listening happily to a mid-level Ortofon MC feeding a stepup pre-pre of my design, and the loading is mostly just the cable and paralleled JFET (3 2SK170 operated at Idss) capacitance. Although my high frequency hearing is not like the days of my youth, I think I would notice the sorts of aberrations shown on the extremephono page. So I guess I had better haul out some test records!

Did you see the loading capacitors the guy suggests? Purportedly the flattest (not the most "linear", the usual misnomer again) response is attained with 1.5uF (!) and 68 ohms? I'm tempted to say they are just wacky, but I'll reserve judgment for the moment.

Ultrasonic resonances would be expected electrically for underdamped low inductance cartridges, and if these were excited by program material might cause some funny behavior downstream. But he shows things that are peaking below 20kHz.

As is almost all discussion related to a pre-amp that almost no one has heard and cannot apparently be replicated any more :)

I graduated to MC 30 years ago. But only in the last 2 have I realised that I had not given MM a fair crack of the whip. Despite the old guard of the time advocating low tracking force low mass MM designs (and the inventor of the MC saying it wasn't worth while) I wanted to be with the trendy stuff the magazines were writing about.

Took me a while for it to sink in that it was time to think for myself on this. HiFi has this strange way of making otherwise rational people irrational. And having done some research I've not found anything to suggest MM is inferior to MC provided your preamp is up to it (and most are not).

But whilst I continue to research I think my rig is far enough up the law of diminishing returns that I'm not missing much.

Actually their is a point in it unrelated to spelling: A P-P isnt name dropping just relating mechanical to electronic watches and their real or perceived value is not a lot Unlike LP and CD.
[hows that fer grammer]

Not really. The LP equivalent is owning a mechanical watch and having a heated winder for it to sit on when not on your wrist. Apparently wrist temperature helps to keep the lubricants at the right viscosity. I kid you not, I have met people who are into this. They make me look sane :D

I've had several. Expensive and less so. I have one now, in fact. The Technics was better than any of them, and the A-T is as good as any of them. Sneering at Technics as a "cost effective" brand thoroughly ignores their market position in the '70s and '80s- their turntables, tonearms, and cartridges were the best around, very high priced for the time, and are still as good as 99% of what's out there.

The equation of expensive and good is ridiculous, except as market promotion.
 
What kind of auto tires do you buy, SY? The cheapest, offbrand? Perhaps for a family car in the city, you can get away with it. If you have a sports car, or another 'performance' auto, it might be best to invest in the known and proven by auto reviewers. Same with phono cartridges. Cheap to purchase, is cheap to produce, and not the best engineering example for just about anything.
 
Ortofon is a difficult company to evaluate. I started using SPU MC cartridges in 1965, and compared with Shure and such, it was amazing. In 1974, I visited Ortofon and we were given a Shibata (sp) tipped MC, that we took to our lab to measure. We found, to our dismay, that the tip was improperly aligned with the cantilever, and we could not get the x-talk right. Sloppy manufacture, and a disappointment.
Years later, I was given an MC30 and I passed it on to my associate, who still uses it, today, with a Vendetta-CTC Blowtorch combination, like most of my colleagues. He is not as 'fussy' as I am, but he still loves vinyl playback.
I prefer even more expensive and exotic cartridges, that my ear has shown me to be better yet.
 
It has been my experience that within a given line of cartridges, the more expensive ones have more 'refinement' in construction, materials, even conception. I have never seen the reverse. It is a lot like automobile tires. More expensive ones, usually handle the road better, all else being equal to the quality of the tire. I learned this with an old Porsche, as I never thought that a difference in tires could make so much difference, when the cheap set was removed, and a 'better' set was put on. Without the actual driving experience, I would not know this, today. For decades, I stuck with the manufacturer's original tire, thinking it was optimum for the vehicle. Apparently, better tires cost more, just like phono cartridges.
