I mostly use transformers, and have not tinkered with the load resistance on my SS head amp. When I had it built I had the option of an extra set of RCA jacks for loading and decided I preferred as few additional connections for a 200 - 300uV signal to flow through as possible, so the load resistance is fixed at 100 ohms as that seems to work well with my SPUs and a DL-103D I still have.

Long ago I experimented extensively with the Monster Alpha II HOMC, the manufacturer recommended 47K and I ended up preferring 1K..

The DL-103 works well at 100 ohms, but could easily work better at some other value - I didn't investigate.

The improvement at a 5K1 loading was quite noticeable, compared to 100 ohms.

I would have to say you've never heard your D103 sounding at its best, then.

It's long gone, it was the first stop on my LOMC journey, without it I would probably have not continued playing vinyl however..
