Hello,
The Beogram RX doesn't have the sloping front of Beomaster 2400, but the setup will play fine together. I would suggest a Beogram 2400-series instead, it is made for Beomaster 2400.
Another cool setup from the "audio-range" could be Beomaster 3000(-2) and Beogram 1200, Beomaster 1400-1500 and Beogram 1900/1902 or a Beocenter instead with integrated record player. Beocenter 3300 is a Beomaster 2200 (a very reliable and well made receiver) with a Beogram 1902 integrated. The older turntables (pre-1982) use the older cartrigde system which is easier to find a functioning sample of.
