While I don't disagree with Judy426's assertions. and my last ARC product was purchased more than two decades ago, my own take on this is that many audiophiles who have toiled through the process of learning what listening is all about (I bought my first component system in 1964), soon discover that personal taste can override reality.
In addition to those recommendations, I'd have to include any number of the currently available Chinese products that appear to offer performance bettering many of their higher-priced domestic counterparts. Having just recently heard the new ModWright Labs preamp, I'd have to include this among those I might have to concede is better than your garden variety ARC piece.
As to your question about impedance matching of a SS amp to a tube preamp, I'm confident in saying that the good designs are within tolerances that most makers are using, and that this would be less of a problem than you seem to think it will be. Nonetheless there are issues between components that need to be addressed. Some, like the Rogue, invert phase/polarity -- which means that you will need to reverse your speaker cable's leads unless your amplifier also inverts. Beyond that, you will find that tonal balance varies, so you would want to select a preamp that is complimentary to that balance and bandwidth of your chosen amplifier.
In the end, though, the ultimate decision as to what works for you should be your own. It's what makes you happy that counts most.
