What dealers are mostly selling is of little importance. Flavour of the month etc, etc. What sounds best to you is best for you. Because I work in the industry, I have played most brands and models, and GK does it for me, also Phil Jones Bass (PJB) and Walter Woods. Why? Because I can get a great sound with no preamp and with tone knobs set flat at 12 o'clock. Eden, SWR, Trace, Ampeg, Ashdown, Fender, Peavey, all capable of great sounds but with a lot of knob-twiddling, and some definitely required a preamp. EBS I have no experience of, likewise TC. All this is just what works for me. BTW, I mainly play upright bass.
