I am absolutely stoked with the quality of 99.9% of HMX DLC and 90+% of RBN songs. I use an old (but very awesome) Onkyo receiver with two sets of speakers plus a sub, and I literally COULD NOT BE HAPPIER with the overwhelming majority of my 1430 songs! There are a couple here and there that don't sound as clean on RB as they do on CD for some reason (i.e. Constant Motion) and a couple of re-records that are less than stellar (Last Resort), but I don't even notice the overwhelming majority of volume differences because to me, it is just a fact of life. If I listen to the radio, I'm going to hear volume differences, if I put in a slew of CDs and shuffle them, I'll definitely hear volume differences. I do agree with an earlier poster that some of the RBN songs are extremely loud for some reason, especially the Children of Nova songs, but I have no complaints overall whatsoever in regards to the topic of this thread.
KEEP UP THE AWESOME DLC AND QUALITY HMX!!!
