Definately B&W Loudspeakers,AR,Classe,Mark Levinson,Perreaux ,Klipsch, & Magnepan just to name a few . I would not touch McIntosh, Wilson, or ayre with a 10 foot pole. This is just my opinion.
I'll mention two not said so far... Wilson Speakers and conrad-johnson electronics.  I've had good resale and trade in experience with both.
Without a doubt McIntosh,a few of the ultra high wattage are even bringing 75 % of retail purchase price under 2 years old .
