You said hardware but the list didn't mention DVD.For best bets there Sony or Denon for $1K or less are best bets.Anice solid rack goes a long way topward enjoyment if your itching to spend some more.I noticed that one of the A'gon dealers had a 4 or 5 shelf Sound Anchor which is heavy iron and can't be beat.List is $1K but used is $500 plus what has to be some pricey shipping.Points under your main speakers and again the heaviest duty stands you can find especially if you have wood floors.I sold B&W for 6 years and folks were blown away at how much a good stand with proper placement could do for a system.If you concrete floors weight nopt as important.Spend what you like on wire and if you can choose better with a return policy if it does not give you the return you want over stock.Give up on the NAD.If it does not perform as well as the 2 channel,older cheaper stuff go with another reciver or maybe even used seprates that you can afford.That last bit of advice is comming from a 2 channel vinyl oriented person but it depends on how much music versus HT you will now use this for.But if you can re-hook up the old amp and new one does not perform as well go back to this dealer and say wwe have to work this out.
