Crossovers, why so few options?

It seems like if you're in the market for an external crossover, there just aren't many options, particularly if you don't want a piece that belongs in a rack mount (e.g. Behringer, Rane).

Why is this the case? It seems like external crossovers would be in pretty widespread use, but the selection is much less than in the amp/preamp space. On all of Audiogon, there are only two or three crossovers for sale at the moment...

Does anyone here use an active crossover with a tube preamp? It seems like the input impedance on most active crossovers is pretty low as compared to tube/SS amps; has this been an issue for you in matching the preamp to the crossover?

Bob, I wonder if the NHT preserves the analog signal for the mains. If so, this is interesting. If it adds an additional stage of digital processing before output to mains, I would not be so pleased. Sub out doesn't matter so much (whether there is digital processing).

Rrolack,

My LS-25 is a tube pre-amp. No issues with the x-2.

The NHT x-2 operates entirely in the analog domain.

I actually emailed HNT, they told me the input impedance for the X2 is 10k ohms (seems rather low). I don't see how this wouldn't cause a problem with many tube preamps.
