+1 on the Coda. I have yet to find a speaker that it will not play well with. Why limit your speaker selection with relatively low output integrated amps when you can be set for life with the Coda.
Building a system based on resale value is one of many roads to disaster in this hobby. Why not buy something really good that works with your speakers and be done with it. Unless that is, you picked the wrong speakers for your tastes and environment. Then the endless dance of changing out proceeding components in the hopeless attempt to change the character of the speakers begins. Very common. Dealers love this.
You can also look at resale value a different way. Many products that have decent resale value, do so because much of the manufacturer's budget is used for marketing. It's very expensive if done right and the consumer pays for a chunk of it. So, for example, Pass will have good resale value because of all the money they put into marketing. Coda put all their money into their gear, none for marketing. Based on my experience you're getting slightly better sound for less money with Coda.
It also seems like US buyers are more susceptible to marketing. Coda is huge in Asia and Europe (where most of their product goes). Why these audiophiles are less susceptible to marketing is anyone's guess.
