New DAC or Speakers? What will put airy-ness in?

What is your budget? Are you wanting a Tube amp or SS amp ?
For around $1000 + - you can get a nice SET tube amp that will let you walk around in the sound stage.
I have an Almarro A318B and it is very three dimensional.
It's a high current amp that has powerful bass and very extended highs. The mids are SET mids (lush and full).
There are plenty of reviews out there on this amp.
It would get you started. The $1000 I mentioned is for a used one.
Hope this helps.

Yeah i am shooting for under $1000, and i do not care if it is tubes or solid state, though i really do like the solid bass of solid state stuff, i will look into the Almarro

Okay so i have really upgraded the setup and i think i am finally almost "there" if there is such a thing...

I now am running a Classe CP-45 preamp

B&K ST2140 amplifier connected via balanced XLRs to Classe pre

Revel Concerta M12 bookshelf monitors

And the same Pioneer ELITE BDP-05Fd blu-ray player

Turns out the ELITE disc spinner is not too shabby, it really was the processor and the speakers that were hold the sound back.

Everything is MUCH MUCH more open and definitely has that airy-ness that i am looking for!

Now, what will take me to the next level? An older / better CD only player like a Classe CDP.5 that i had before or perhaps a nice DAC like the PS Audio Digilink III ?

Is there going to be a marked improvement going with the PS Audio DAC over the dac that is in my ELITE player? Thanks!
