Stand-alone phono amps?

The Manley Steelhead is a very flexible phono amp that can switch to a line level input when desired. Sonically, I would characterize it as having quiet backgrounds and colorful dynamics.

Could you clarify your question? Are you asking if phono stages exist??

Your correct that a "stand-alone" phono preamp, which used to be known as a "preamp", before the rise of CD and the (temporary) eclipse of vinyl, gives most bang for the buck. Not only are the phono and linestages on one chassis, but also you don't have to buy and/or fret about an IC to connect them. I wouldn't do it any other way. You mention the Counterpoint SA9, but in fact I always thought that was a phono stage designed to be used with the SA11. Perhaps it does have a volume control but it may not have enough hi-level inputs to do the trick. Nevertheless, there are many, many excellent full-function preamps to choose from, both tube and ss types, starting with Ayre and perhaps not even ending with Zanden (if you can afford it). I use an Atma-sphere MP1 (which I now see would alphabetically precede Ayre) and love it. The full function preamp has made a major comeback in recent years due to the uptick in interest in vinyl.
