Hi Paperw8...the Whest manual merely says "0.6mV-0.35mV = 55db setting", "0.4mV-0.25mV = 60db"(personally I would have written these numbers in reverse but never mind :o) Given that Lyra requests a "0.6mV or less" input, 55 chose itself. I hear what you're saying about low throughput. My concern was driving the phono stage into saturation.
55dB is a very workable setting with the lyra delos. i tried that setting and had no difficulty. for me it was just a matter of preference that i wanted to provide a signal that was at least equal to the input sensitivity of the preamplifier. but i think that jonathan can provide some useful observations on this point.
driving the whest into saturation isn't a problem. i have used 65dB gain with the lyra delos without difficulty. i would expect the whest to be able to provide a signal output level of at least 2v. the problem that you can run into is that you send a really "hot" signal to the preamplifier. then the output volume can get pretty loud even when you have the volume at the 9 o'clock position. not only can that make it more difficult to finely control the volume level, but it would make the volume adjustment way out of line with other sources that you might send to the preamplifier.
