No problem! One thing you should probably check is the frequency response of your speakers. Once you get the Marantz you will need to set the crossover for your speakers, or have audyssey try to do it for you. If they are small satellites, it's a good probability that they will require a higher crossover setting at 120 Hz or above. You can also use our Hsu BAS Test CD test tones, along with a sound level meter, to determine where they roll off.
The HB-1 Mk2s and HC-1 Mk2s should work well with the Marantz SR6005. If you do end up getting the HB-1 Mk2 and HC-1 Mk2, a good crossover to select would be 80 Hz.
