I bought my new SME 10/A with a Sumiko Celebration new in 2003. Great combination. The cartridge has great bass and is just slightly warm of neutral, IMO. I have since upgraded to an SME V arm and AirTight PC-1 cartridge.
I also found that replacing the stock cable helps. I first tried a Harmonic Technology Copper Phono cable and now have the Hovland MG2. Also, given that the SME 10 is unsuspended, a used Townshend Seismic Sink will do wonders for isolation.
Congratulations. IMO, the SME 10 is one of the great values in turntables today. It's a very good table/arm combination and the Sumiko cartridge was developed and voiced on an SME 30/V arm combination, so it is an excellent match. There are a few reviews on the net.
