The C320BEE is a wonderful sounding amp. If you want to know whether the 50 watts of the C320BEE is enough, do the following.
Buy a cheap digital multimeter which you can get for less than $20. Buy a test CD with a -20dB test tone, [probably better if it is not pink noise]. [I can help you if you cannot find one.]
Select the AC voltage scale on the multimeter that allows you to measure up to 2 volts or so. [Make sure you have selected the correct scale.] Place one of the multimeter test leads on one terminal of your speakers. Place the other on the other speaker terminal. Play the -20dB test tone, with the volume low and turn up the volume until the meter reads 1.4 volts. [If the meter gives no reading, do not just keep turning up the volume; find out what is wrong.] [If your speaker impedance drops below 4 ohms down to 2 at some frequencies, then you might want to stop at 1 volt instead.]
Once you have found the setting that gives 1.4 volts, leave the volume control there and play a bunch of CDs, taking notice of how loud the music is. If that is not loud enough, you will probably need more power than the C320BEE can deliver. It would be best to step up to at least 150 watts if you are going to step up at all. Note, if you play vinyl, you will probably need more power than if you play CDs because the warps eat up a lot of amp power.
