"Harder" cartridge recomendation

You might consider a decca MI (or an ikeda cart, which are based on the same design principles as the deccas) - as fast and dynamic are what these carts are renkowned for.

Not sure how well it might match the 3012R though...

Halco, Nandric, I have no idea about the persons you are mentioning, apart from one of them kindly sending me some useful info via PM and then asking not to ask him any Q's again as he will not reply... IIRC, he was/is some automotive consultant, hence the automotive analogies???
(BTW, I do not deal with underwear...used nor new ;-))

Anyway, it seems that getting FR7 is sort of an underground activity in some gnostic circle...Again, having a cart in my hand how would I know if it's ok or I'm being fooled?
Also, what is the right price?
Halcro, my arm is SME3012R. So, hypothetically thinking, would it be "appropriate"?
Thanks!

Bydlo, The person who asked you not to ask any Q's should
induce you to think about yourself. You are difficult to
satisfy , obviously. Like a public servant who invents
contra questions for any question asked. You should buy whatever cart on ebay and pay via paypal. You will get ebay protection this way. Not sure about the USA but in
Europe this work this way. The payment is blocked for 21
days to give the buyer the time for complaint. This of course means that the 'protection' is at the cost of the seller but is good ad for ebay.

Though it is not my thread if Bydlo doesnt mind, can someone please describe the signature sound of FR7/f/fz carts ? I tried googling for a review but just couldnt find any and these cartridges are very expensive even in the used market so it is not even a case where one can buy to try out. In the end there is definitely some risk in buying a cartridge which is no more in production but still some useful user reviews can always make for a better buying decision. Anyone please ?

Nandric, I think you are very much off the topic of the current thread and I have no idea what made you start this personal attack. Perhaps you should think about your very self?
I group the Q's which popped up within the thread, perhaps there is somebody who may know something, unlike you obviously:

--how does one recognize that a given FR7 specimen is within it's specs, not being familiar with FR7 sound?
--does FR7 match SME3012R?
--what would be aright price for a good FR7?
--how does SPU and TSD families relate sonically, esp. Royal N vs. TSD15SPH, if anything is known?

If they are self-serving "contra Q's for each Q" or "peculiar", I leave to judge the others.

Ahh, and thank you very much for your advice with using Ebay & Paypal...indeed ingenious!

BTW The person I mentioned started his PM with the quoted statement. I did not ask him any hard Q's nor actually wanted to. I've found this behavior sort of bizzare, but I do not care...everybody has his/her own style.
