I own the Manley v2.0 and like it a lot. I use it to drive a pair of Beveridge 2SW speakers via the built-in direct-drive Beveridge amplifiers. You'll need no separate linestage, unless you want multiple high level inputs. The Steelhead only has one high level input.
If you have a big budget, and if you are OK with solid state, you might consider the DSA phono2. It has three totally discrete phono sections on one chassis. Offers a choice of fully balanced or SE inputs and outputs. (Otherwise, only Atma-sphere offers balanced phono inputs, so far as I know.) You can set gain, load, capacitance, etc, independently for each one of the three sections. It's built like a tank, would cost 3X as much if it fell into greedy hands of a marketer. Purely for versatility and flexibility, there's nothing better that I know about, if you like SS.
