"Harder" cartridge recomendation

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.

Pani, not at all: my topis is general as it's stated in the 1st post. I'd be somewhat interested in those sonic impressions too.

Bydlo, You get advice for free but you think that you can
demand the answers according to your own preference. Like
the public 'servant' I already mentioned. You can ,you know what...

Dear Nandric, I have no idea what makes so angry and why you insist on deviating from the subject. I do not "demand" anything, I'm simply curious. If there are no answers to my Q's, ok, no problem, it means there are some gaps in the common pool.
If you feel that I should kiss your ... for you generously posting in this thread, then thank you very much and maybe do not post?
