Hello again.
Raul, I now see what you were saying in pertinence to the 45db setting, in that there is a particular performance gain at that particular setting.
But, as I know you'll agree my friend, that such a gain setting would of course not be any good-compatible,for a Cartridge that has an output of let's say .22mv to .34mv.
Since the Sutherland does have quite good adjustability as far as gain, and loading, it would sort of beillogical to then try to "match the cartridge to the stage", rather than make the needed-required adjustments at the gain, and loading boards.
I see lots of suggestions to the original poster to dump the Sutherland PhD, like a bad habit, and before anybody jumps conclusions, I think maybe one should read Mikey F's review of this Unit.
Mine is certainly nom slouch, and of course I am fully aware there are of course better Phono Stages, and as well, more costly, such as a $7500 manley Steelhead.
I'm not of course going to say the Sutherland can go neck, and neck with it, I'm sure it will not measure up, but will probably exhibit a much more dead silent background, versus even more costly Units.
As two fine friends ere have once taught me, generally go by the "25X Rule" (thanks nsgarch) multiplying times the Cartridge's internal impedance, and another good piece of advice from our forumite Doug Deacon, that yes, do set loading for now to manufacturer's suggested range, but as Doug once told me, "likeable" loading might be all over the place, untill the Cartridge fully settles down, and breaks in.
Hope this helps, Mark
