At least the order page still shows US$900! US$30,000 was a bit of a leap on the price!
 
It all just seems odd and could make MF less credible as a manufacturer. Not sure if the pricing was a joke or not, but the whole affair just seemed odd. Even if Michael wanted to discontinue the MC Pro on grounds of principle, there had to be a more elegant way to do so.

"At least" seems so inappropriate, tho. What a seriously deluded product/price point.
 
REPRICED, PENDING DECISION ON CONTINUATION
10th of December 2024

As of December 2024, all standard MC PROs have been built after a run of over 2 years; a successful outcome and good ending point for the project. Considering popular demand, there may be a small run of units made in the first half of 2025 for UK-based users (or less likely, global market). Following sufficient demand for moving magnet and high-output moving coil front ends, coupled with an ever-clearer picture of the superiority of high-output types and the deficiencies, liabilities, and origins of low-output cartridges (to be fully expanded upon once conclusive), it is possible that all products for low-output may be discontinued due to misalignment with the company's principles.

Having sold a substantial quantity of MM and MC stages direct over the last couple of years, there is a very strong pattern of exogenous noise and setup-related issues pertaining to LOMC types that correlates inversely to output level, while all the measured objective test evidence I've seen so far shows inconclusive variation between the tracking performance of these compared to high-output types. All the historical material, dating back to the 1940s, for the popularity of low-output points towards the greater ease of manufacture with coil lower winding count, when an input transformer would be mandatory for both low and high types as a result of the voltage noise/gain limitations of contemporary valve-based input circuits.

This is a 'sacred cow' in the audio industry that no-one seems willing to challenge, probably due to the ubiquitous esteem it enjoys, quite despite cartridge manufacturers themselves publishing identical frequency range and channel separation characteristics for high and low types alike, which would certainly tend to deviate from each other if the claims of increased inductance and mass effects held true water. It is therefore highly likely that the incremental differences in moving mass are swamped by production tolerances. I would warmly encourage you to make your own observations and keep an eye out for unfalsifiable statements in favour of either variant.

If you've not selected an MC cartridge yet, might I recommend using a high-output type, such as Dynavectors DV-10X, DV20X, or Hana MH which have proved to be every bit as good as the AT cartridges, and use the MM Pro in the 52dB gain setting instead. It's also substantially lower cost + allows you to use normal MM cartridges, many of which are very good. Ultimately, it's important that the chance of success is maximised in any situation containing unknown variables. If I were in your position, with what I perceive your budget may be, I would go with the Dynavector DV-20 X2 (2.8mV version) + MM Pro at either 42dB or 52dB (depending on the sensitivity of the rest of your setup) and call it a day. You'd have a bit to spare for a conical MM for those worn discs + mono switch.

Now standardised in black for £25,000/€70,000/$30,000 direct from Classic Audio Ltd.

It's interesting that MF seems to be blind to human nature given the extremes of his engineering prowess. It's more likely that an audiophile would give up a specific phono brand than switch from their preferred cartridge type, in my opinion.

To not actively continue to address the LOMC market with a superior MC phono on the basis that HOMC + MM phono is better from an engineering basis seems to be walking away from a large part of the vinyl market before you'd really become well-known in the space. Makes it harder for me to recommend MF's MM products, as well. It's not like we don't all know that vinyl is already an anachronistic technology.

But, perhaps it's just a stunt.
 
Bearing in mind low stock levels, and recent developments in the market, I have increased the price slightly...
Could you explain a bit more about the "slight" changes in stock levels and especially the market developments?
 
Oh, I thought this was a play on the TE affair. Is it really not?

In any event, I'm still very happy with my MM Pro (dismissed MC carts a while ago now).

In whichever direction Classic Audio goes, I wish Michael all the best.

Mani.

He's taking the piss.

25,000 pounds is the price of the Tom Evans Mastergroove which has been exposed and ridiculed recently.

@Michael Fidler You're a funny guy.

Good that you're including post and packaging. That way you can ensure it does't arrive as matchsticks.

Brilliant! Made me laugh. Of course, with the "SLAPP" on Mendit Mark, some people may miss the British irony.
 
But a WAY better deal than that other guy's, I think. Me, personally, I stick with MM.
Ha, I didn't know much about this product when I saw his revised price and at first I thought it was serious and he'd meant just £25 and forgot to use a full stop rather than the comma he used, and then I read some more posts and saw it was a joke in reference to a competitors product & price of the competitors product. Ha, either way I knew he didn't really mean 25 Grand, ha!
 
I guess nothing more than a joke due to that recent video on YouTube!

It brought a bit of a smile to my face!

Are you serious? Or just seriously deluded?

Sir, if I am deluded for offering a product at this price, then you should be aware that you may also be calling the creator of the 'Mastergroove' deluded! No serious audiophile would agree with that kind of opprobrious assertion.

Well, I only ordered the parts to make a certain number of them, and I always prefer to deal with the MM side of the business. As demand for the MM products is strong enough to consume all the time I'm willing to spend making boards, I decided to give it a rest for the time being at least.

Low-output cartridges cause so many setup issues that would be innocuous at MM levels to become objectionable when the gain is increased + the user compares the setup hum against the noise floor with the gain up, so a lower noise floor product is perceived to have 'more hum' - a nightmare from a customer-service perspective!

I posted my views about this last week. I was already declining 90% of orders to prospective LOMC users who hadn't yet got a working setup, especially if a Rega turntable (no ground wire = big hum liability) was involved. But then I received quite a few e-mails after the last one was sold from people who weren't exactly happy with the decision. Following feedback from the market, I decided to make a few more MC Pros as part of a special batch.

Having learned that tantalum capacitors dramatically improve the mid-range refinement and dynamic slam of a product, I decided to use some very high-end new-old-stock parts, originally intended for a Soviet intercontinental ballistic missile system. Unfortunately, these are very expensive parts, and the chap in Russia who I bought them from wanted 392,000 Rubles a piece - roughly GBP3035. In pursuit of ever-improved bass authority and top-end crispiness, I begrudgingly paid up, but being a magnanimous fellow I decided to do the best I could to shield the customer from the increased parts cost, by adding no margin on top of this. With eight of these capacitors in each unit, this has sadly increased the total price by GBP24,280 - from GBP720 to GBP25,000. I definitely have a batch of these units on the shelf, ready to go as soon as somebody pays for the greater parts cost, I just can't show you a picture of them as my SLR and phone camera don't seem to be working.

I thought you boys would be proud of me for my commitment to continuous improvement - it's very disappointing to hear that some of you are not taking me seriously here. Any parallel to the Tom Evans debacle is purely coincidental. In fact, Tom is to be commended for his generous use of beneficial tantalum capacitors while keeping the final price of 25k so very reasonable. As there may be new developments underway, I have decided to review the price again before the 1st of April 2025. Hopefully, the addition of this deadline will have a soothing effect.
 
Very "british" humor...

@Michael Fidler are you indeed considering phasing the MC Pro out? Will there be a new product introduced for low output MC cartridges? E.g. a "MC Pro II" with balanced inputs?
