Breaking in a new cartridge,..Denon DL 103 R.

As Rodman said the frequency figure is based on them using a 47K load.
Their suggestion is to use 100 ohms in the phono amp
or 40 ohms if using a transformer.
I have elect the 100 load over the 470 or the 30 that
my Dynavector p-75 provides.
This phono actually provides another load option called
the '' phono enhancer '' or 0 load option.........this is where my regular DL 103 likes to be connected.....unlike it's little cousin....it seems so far.
Again they also differ when I select the setting relate to the resistance......the 103 prefer the medium setting while the 103R prefer the high setting.
All and all it's a little time consuming and I thank all
the one that have shipped in.
By the way does 47K ohms represente the same figure
than 470 ohms ?

47K ohms is actually 47,000 ohms. The 103R should sound quite good into the 100 ohm load; the other setting that you should try out is the 30 ohm load. It is quite possible that it will sound even better to you there. Don't worry about it if it doesn't as this is a subjective hobby and there are many things to take into account such as system synergy, related pieces of equipment etc.

My advice would be to get 15-20 hours on the cartridge tracking it around 2.6 or 2.7 grams using that 100 ohm load and then try the 30 ohm load. I'm not familiar with the Dyna phono stage, but it sounds like the "resistance" setting is actually a gain setting, with "high" giving the higher gain. With the lower output of the 103R vs. the straight 103, it would make sense that the R would prefer that "high" setting.

Good luck and enjoy your 103R. It is a great cartridge (especially for the money!!!).

To speed cartridge break in I get a real cheap, brand new 45 RPM dance single ($2 or so) and play it on for a few times each day (at low volume levels). Them heavy bass modulations @ 45 RPM are quite something! I use a particular Spanish Flamenco-Disco that uses a really loud kick drum beat. Works for me.

Let me join in and support "hdm" and "Psychicanimal" sagacious advice. A 7" 45 RPM record dance record with lots of octave divided synthesized bass is GREAT for break-in because 45's are cut 12dB hotter than LPs. I do not know if 45 EPs are cut hotter as well or not. After 10-15 hours you will know basically what you have and between there and 50-60 hours it just gets better - kind of "warms up".

For cartridge matching please see my old primer article on 6 Moons Audio (I think that it is still there?). The DCR is 40 Ohms and the impedance is well .. who knows... cartridge impedance is a misnomer. The 100 Ohm load thing is just a convenient guess, or starting point, provided by the manufacturer. The overall electrical system is too complex for any absolutes - it all MUST be derived empirically.

My advice? No? Well I'll give it anyway... eventually try to forget active (head amp) and go with transformers for MC step-up! The UTC A-11 based box I built for Jeff Day's Denon 103D or the Altec 4722 sound simply wonderful with the 103R,D,S, etc. series.
Active's are nice at being flexible for a wide range of cartridges but a good transformer is far superior at really hearing the cartridge.

The DENON MC cartridges are absolutely a bargain! Even in today's market! Yes, they have their foibles and limitations but they definitely provide "most bang for the buck!" OTOH, they just might get you hooked on MC cartridges. ;^)
