what to buy first

+1 for speakers first. IMO every manufacturer has a 'house' sound and variations within that. Even if your amp or source is "isn't good enough" for optimal sound the speakers can deliver you now have an idea where to go next. Personally I don't look at specs because I've never seen a spec that will tell you how it sounds. For that reason YOU need to decide what speakers you want. For a suggestion I would recommend you listen to Dynaudio - Magico - Raidho - YG. They all sound different. Again YOU need to make that choice.

For tubes I had Octave in the past and they make wonderful sounding amps that are pretty bullet proof.

Best of luck

Thank you so much for the above responses.  It is difficult for me to listen equipment in my area.  Are there any good audio shows coming up that I might attend.  I know about RMAF in October, any sooner?

That's a huge room, are you really set on tubes?  I'd get a big pair of maggies and a 400+ watt solid state muscle amp and a pair of subs.  Then invite a bunch of friends over for the concert.  I hope your neighbors don't live too close. Oh yeah get a tube pre if you need something to glow.
