Dear Almandog: As you can read each one has its own take, this is mine.
The Denon DLS1 is IMHO a way way better cartridge quality performer than your Dyna's. To be in the same league than the DLS1 you need something like the Dyna XV-1s.
So, I think that you need a phonoline stage that can " honor " the DLS1 quality and that has very high gain ( with out SUT that degrade the cartridge signal. ) with no-noise due that the Denon is very low output.
What to choose about depends on your main audio/music targets/priorities.
If what you are looking is to hear what's in the recording then you need IMHO a phonolinestage that be: neutral/accurate, IMHO there is no other way.
If what you are looking is that " soundstage, false 3D ( that does not came in the recording. ), colored sound " then your choice must be different.
In the first case the choice is a good SS design ( not that ASR. ) and maybe one or two good tube designs that IMHO are not any one you name it.
In the second case you can choose almost anything: tube or SS.
There are several factors that could tell us that for that DLS1 a good SS design is the way to go but in the other side I know that are persons that think in a different way.
I think, as I said, that you need to choose according with your targets.
Now, an investement in an audio item like this one you want to do needs that in some way you try to hear ( the preference in your system. ) different phonolinepreamps where you can near sure what goes with what you are looking for because if you buy at " random " then maybe in six months you will be looking for a new unit.
Regards and enjoy the music,
Raul.
