In my case there would be a difference in appearance, I have Beomaster and Beogram 6500 in white (including the same MCP 6500), there is Beocord and Beogram CD in white on the Polish market, but probably beyond my financial reach at the moment. However, these two elements from the 7000 series are at a good price, but fully black. In total, two white and two black elements would also be ok. 😉
