Is it easier to sell mono blocks or stereo amp on the used market?

Amps are heavy, especially as you age.  Monoblocks are lighter, (but not 50% lighter). 

Not sure aobut selling.

Have the models been on the market long enough to compare their selling history on Hifishark? Or to extrapolate from other Macs that have sold over the last few years? (I don't know the answer to your question but I'd think that monoblocks are more niche to the general public and you might have a bigger resale market with single amp--but I really have no idea.)

I might ask how committed you are to the decision of buying the new amps, if your first concern is how easy will they be to sell.  I say buy what you think you will enjoy the most right now.  Who knows, you may have them for 10 years and the resale question is moot.  IMHO.  Cheers.

+1, “buy what you think you will enjoy the most right now”. And also what amplifier sounds the best to you.

Two mono block amps or a single stereo amp decision depends on what sounds best to you in your home audio system. Concern about space also needs to be considered (one box or two). In my case, I decided on an integrated amp.

In summary, “The decision between two monoblock amplifiers and a single stereo amplifier depends on your specific needs and preferences:
    •    Sound Quality: Monoblocks offer better channel separation and reduced crosstalk, ideal for high-end systems. However, modern stereo amps often have negligible interference, making the difference minimal for most users.
    •    Power Needs: Monoblocks generally provide higher power output, suitable for demanding speakers.
    •    Space and Cost: Stereo amps are more compact and cost-effective, while monoblocks require more space and are pricier per channel.
    •    Practicality: Stereo amps simplify setup, while monoblocks allow flexibility in placement and shorter speaker cables”.
