Don't use this to lube your VPI Classic bearing
Dave, You forgot to add, "Bahdum-dum", a la Law and Order. 
Who needs a MM cartridge type when we have MC?
David, Are you listening to and liking the AT150ANV? 
Who needs a MM cartridge type when we have MC?
Al, Why do we care about RF? This is an MM phono cartridge that is probably not doing anything at those frequencies. If RF is picked up spuriously, then all bets are off, I guess. But it's not like bypassing an IC or similar, where we do want the ... 
Who needs a MM cartridge type when we have MC?
Can't edit my last post, but I meant to add that your comments make me think of a third alternative, mount no resistor on the PCB and all loading is done from the switch. Thus one is not paralleling resistors, if that could raise issues. There are... 
Who needs a MM cartridge type when we have MC?
Thanks, Al. Much of what you say are reasons why I have hesitated to install the switch. Obviously, any such set-up will add some noise, even just the switch itself. I had planned originally to keep the 100K load resistor in place on the PCB, wher... 
Who needs a MM cartridge type when we have MC?
Ideally, one wants two controls, one for R and a separate and independent one for C. Many vintage preamplifiers provided both. I just don't have room for two ELMAs on the rear of my MM phono stage, so I will have to make some educated guesses as t... 
Who needs a MM cartridge type when we have MC?
Thanks everyone for your informative responses.Dlaloum, How do you "measure the frequency response" of your MM cartridges, meaning what tools do you use for that? I am inclined to be lazy and just go by my subjective "feeling". Thus I "feel" that ... 
Who needs a MM cartridge type when we have MC?
Thanks, Ecir. I know how to calculate the values, and I have already decided to use an ELMA 12-pole stereo switch that I bought from M Percy and which I know will fit nicely at the rear of my MM phono stage. My question was really about what value... 
Who needs a MM cartridge type when we have MC?
Nandric, If you are the buyer, why should the (German) seller hate the Paypal fees, if you presumably pay them? I only hate the fees when I am the buyer and have to pay them. In any case, the time is ripe for Paypal to have a competitor who charge... 
market value???
There are not enough of those around, the DP45F, specifically, to establish a "market value", so there really can be no answer to your question. In the end, I think your unit would sell faster than a unit that is sold with no guarantee of conditio... 
Sota Sapphire & Lenco 75..
Just to be more clear, when I wrote that the Lenco with everything properly adjusted but still in its stock box chassis would outperform the Sota Sapphire, I meant table vs table. IMO, the Lenco tonearm is best avoided. The Acos is a very good upg... 
Who needs a MM cartridge type when we have MC?
Dear Raul,Do you mean to say that you hold 100K as a constant and vary only the added capacitance? That would be fine by me, but I was given to understand from certain posts by Dlaloum and Timeltel and perhaps others that there are cartridges that... 
Who needs a MM cartridge type when we have MC?
Dear Nandric, I am sure that in some cases your analysis is accurate, as regards why US sellers (or German or wherever) may not want to sell to persons outside their own borders. But there are other perfectly understandable reasons for adopting su... 
Sota Sapphire & Lenco 75..
Sota if Lenco has original arm.Lenco if with Acos Lustre, a fine tonearm. IMO, even a stock Lenco in proper trim in stock chassis, with everything adjusted properly and working up to spec, will be superior to the Sota Sapphire. I own or have owned... 
MM Phono Input impedance change 47k to 100k ohms
I fully agree with everyone else; there is nothing "wrong" with using a 47K load with the Grace or any other MM cartridge. (And, as I think I wrote above, I was not aware that Grace recommended a 100K load, if that is the case.) It's just a matter...
