Is this a good match? Sometimes it sounds a bit thin or too bright. The preamp's input resistance is 47K: could it be a load problem (not that I understand what that means) and what could I do about it?
Thanks.

Hi there
Denon 103 through a stepup can be a bit of challenge.au
The lowend Denon trannys (au250-au340)do the job. but just barely. the 103x is
a fine cartreidge and needs a better stepup. i suggest trying the $700 denon tranny (au-s1? if i rememeber) from audiocubes (unfortunately i have not heard this but it seems a good value) or the jensen wiht the 40 ohm setting. next best would be bent(s&b) on 1:10 ratio and appropriate resistor value. if you can find the au-1000, grab it.. its really good. also, if you really love the 103 soound i would suggest contacting tribute or sowter to make a special tranny for you. also, the consonance 40m ohm tranny is a good place-holder till you get something better (i preferred the consonace to 320/340).

to be used together.But others have reported the same when using the "40ohm" input. Try the other input. It will be quieter but ignore that and just turn up the volume.
And was interested in trying the 3 ohm position on the AU-320 after reading about it here, despite Denon's recommodation of 40 ohms. After trying it (way too bright, etched, and artificial sounding for me), I'll stick with 40. Obviously YMMV.
I too donot think it sounds as good as it can "as is", i.e. the 1:36 (3 ohm) position. The source impedance of 50K plus into the preamp is too high.
My phonostage is a custom designed, tubed unit that is built around as a Moscode SuperIt, now including a shunt regulator and massive tubed power supply. It can handle the DL-103 straight in (and doesn't sound half bad that way, with very little tube rush), but with the AU-320 set at 40 Ohms the DL-103 sounds simply fabulous. The 3 Ohm position, for whatever reason, simply doesn't sound as good.
I'm only saying the 1:36 ratio setting allows one to load the cartridge differently and still have sufficient gain and a low impedance source for the preamp, an often overlooked parameter.Cheers!
about the 3 Ohm setting. While it _is_ more lively, I was noticing more of a sizzle on cymbals, and they seemed to be separate, not of a piece with the rest of the presentation. The 40 Ohm setting seemed to remedy this.Actually the 3 Ohm setting seems to have higher gain in my system.
The 3 ohm input is the 1:36 step-up and the cartridge sees about 35ohms load impedance. The 40 ohm tap is 1:10 and 470 ohm load. The load on the 3 ohm tap halves the cartridge output but is multiplied by 36. The 40 ohm tap does not attenuate the ouput but only multiplies it by 10. That works outs to be abut the same.
I actually prefer the 1:36 ratio but with a 1.5K load resistor in parallel with the preamp which results in a little more than 1 ohm load for the cartridge and a low source impedance for the preamp. In the normal 1:10 and 1:36 modes the source impedance for the preamp is around 4k or 51k, pretty high.Cheers!
in a Y-adapter on the pre input. Any drawbacks there?
Take a look at this thread for some ideas to try...
