I'm fairly pleased with this system. In my small room it does sound real nice. No low end of course. I'm thinking of eventually adding full range speakers or trying Naim amplification. But I guess I'm in no real hurry. This is the most content I've been with my stereo in about 3 years.
No, I haven't had any problems with the Richmonds. Which version do you have? I think mine are the 2's the port is in the front. The 3's have the port in the back.
Before I bought the Planet I was using a Marantz Cd changer for CD playback. I can say that the Planet did add a fair amount of bass that the Marantz lacked. I welcomed the increase of bass in my system. It now is a little warmer and fuller sounding all the way around.
