I have a Harman Kardon AV 75 receiver, Cambridge soundworks Ensemble
speakers, Cambridge Soundworks surround and center channel speakers
and will be purchasing a universal SACD/DVD-Audio DVD player -
probably a Pioneer Elite DVD 47Ai.  Can you tell me if this will all
work together?

Yes, I think so, for you have chosen good equipment brands. However,
don't forget that the final and fine tuning of a system happens when
you carefully choose audio cabling to go with the electronics. I can
recommend you have a look at www.audiogon.com, where you can find
second-hand audio cables which otherwise would be quite expensive. For
example, try NBS or Siltech cables for interconnect and speaker
cables. They have the ability to change the final sound of a system.
NBS produces a warm and intimate sound, and Siltech improves imaging
and spatiality. You may blend these two brands in order to balance the
effect brought in by each. In principle, you have made sensible
choices.

Thanks.  The HK receiver doesn't have 6 analog inputs to connect to
the Universal SACD/DVD player.  Is there any piece of equipment that i
can put in between the receiver and the player or do I need to upgrade
to a new receiver?
