what should I upgrade next?

Too late now but a unified Linn system was available with a Linn Classik Movie System.

Rich,

Thanks for you answer. The sound from my old NAD 302 had better low freq response to the front speakers. The NAD T753 receiver doesn't come even close. Of course the sub can compensated for that, but I have the feeling that I am not getting the sound that I expected from the front speaker (I cannot really compare the rest of the speakers, since I never had HT setup before). I played with the crossover settings, I also removed the sub completely but the front speakers still did not performed as well as on the NAD 302. Maybe this is just a fact and I have to live with it. Or maybe I should used the pre-out (for the front speakers) on the receiver and connect them to the 302 - that way I will be using the 302 power amp and this could be a solution.
Then there is also the hiss issue, which my old 302 did not have. I read about it in the forums before I made the purchase, but my understanding was that this was fixed with the new version (T753, software version 2.0). I am waiting on the new receiver and if it has the hiss again, I will try to return it and get something else.
I spent almost 3+K on the setup, and now I don't think it was worth it.
All this combined triggered this post - I think I messed up somewhere with my hardware selection and that's why I asked for help.
Sorry for the long post.

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.
G'luck

you are probably correct about the DVD player - maybe I should upgrade it next (it's a 5 years old Sony and it costed around $250 when I got it - so I don't think it matches the rest of the equipment in terms of quality).

Talking about DVD players - I believe if I just buy a good DVD player, I will not need an additional CD player, correct? I guess what I am asking is, is it worth to buy a DVD player and additional CD player? Will a good CD player be much better in reproducing music, than a good DVD player?
I guess I have to many questions...
