Impedance loading low-output MC cartridges...


Hello,

Does anyone know if there is a general "rule of thumb" regarding impedance loading of low-output MC cartridges? Most manufacturers do provide some guidlines as to a range of impedance settings that will work well with a particular cartidge, and I have fiddled around with this a bit.

Since it takes at least a few minutes to power down my system, reconfigure some DIP switches in my phono preamplifier, and then power up the system, it is not easy to do a reasonable A/B comparison.

My setup is Basis 1400 / Basis RB300 / Benz Micro ACE (low-output version) / MS Phonomena.

Please fill in the blanks. As impedance increases the sound should _______, and as the impedance decreases the sound should _______.

I can only agree with all which has been said above. I loved the sound of my old Koetsus at 1000 ohms, as ALBERT did, however with the Helikon and also with Peter Suchy's stuff I settled for 47k. Here the dynamics were best and what Albert called splashy, I found especially with sopranos and solo violins a far better rendering of transients. Distortions I only could discover, when the instruments were too closely miked and hence don't think this is systeminherent. A lower setting, will indeed mask this ocurrence, but since it is rare, I didn't mind.
