Thank you all. Very good responses and suggestions. I think many of you are correct. Gain of 54dB is probably fine for the Delos, with the rest of the system cooperating. In my case, I have tube amps and speakers that are not very sensitive, so I need that extra gain from the phono pre.
I changed the phono pre from ARC PH3SE to Whest .30R which I set to 60dB of gain, plus the extra 6dB i tap into by running balanced to my ARC LS25 - problem solved!
I tried a few different loads, and I am at 200 now, which sounds pretty good.
Now I have an excellent ARC PH3SE to sell! Anyone interested?
