If I were to buy a G65 (probably next two years?), how much of quality compromise do I have to take?
You’ll get conflicting views on this as with DSPs as your speakers you are not leaving the digital arena in the processor. IMHO, the main advantage of the 861 is that it can act as a self-contained Roon endpoint via an ID41 card. (I still miss my 861 regarding this!)
Given the 861v8 seems not to evolve anymore, does Meridian offer either some "trade-in" arrangements with the next generation product OR special late-sale discount?
There may or may not be an official trade-in option but in my experience the best Premium dealers offer good trade-in deals.
Is there a place where second hand 861v8 can be found?
Keep a look out in the Restaurant on this forum or even place a wanted add
