Thanks for your observation. I have something to report, now that I have mounted the DL-110. Tracking at exactly 2 grams and 1.8 antiskate on my SME 309 tonearm.
The Shure TTR-117 (ERA V) Test LP is tracked as well as my DL-103R. Not perfect but darned good!
The Hi Fi News Test LP is tracked perfectly including the infamous 4th band at 300 Hz.
A German test Lp is tracked perfectly up to the limit of 100 microns at 300 Hz, which is about equivalent to the HFN recording.
Musical tracking on the Direct To Disc "The King James Version", trumpet solo on "Corner Pocket" song: perfect tracking. Also, full-range big band sound, to include the cymbal treble rythm.
Anitra's Dance (from Peer Gynt) on classical music is passed with complete clarity on the high orchestral bell and very soft violins with exquisite tone. But Dvorak's " Carnival Overture" with full orchestral vigor, begins to show a bit of strain on the full volume scale.
That's where the DL-103R passes with total aplomb and ease. That piece is a " tour de force", with capacity to separate the men from the boys. And it did, up to a subtle point.
So, the DL-110 showed some sign of strain (but not outright mistracking) on one specific, and intentionally difficult band, which I keep for that precise purpose. This might get better with additional playings of the cartridge. But I do not believe in " burning in" cartridges. An iconoclast position.
From a 45 minutes audition one can observe a difference from the higher cost spread, which is small but audible. In perspective, one can detect a subtle point where the DL-110 can be bettered. But the tonal character is the same as the rest of the Denon family...remarkable in itself.
Time for graduation? Possibly.
