The DL-S1 is an unusual cart with an extremely low output and a relatively high impedance. J Carr posted previously (on another thread) that this is because it has a
non-permeable core. The stridency or exaggerated overtones can be due to capacitance reacting in the phono stage causing ultra high frequency overload or oscillation. This happened to me and I had to use another phono stage. Your best solution is to select a phono stage based on anothers positive experience. If you have to load it down to or below the value of it's output impedance, you'll (in theory) cut the eff output in half. Whether or not 60dB is enough gain depends on your system. That's impossible to give a simple answer. Some line stages have 20dB gain, a passive has 0 and your phono stage has to drive the amp. Some spks are 83dB, others are 100dB. I think that 60dB would be a minimum, depending.
If you have to load it below 100 ohms you're probably experiencing this high freq overload, at least to some extent. Optimal loads for some users is 400/500 ohms. This doesn't really have anything to do with with the type of device providing the amplification, although some devices might lend themselves more to direct coupling. Phono stages with response in the ultrasonic region should be more susceptible.
