Seeking more 3d imaging, deeper/wider soundstage


I'm considering replacing either my amp or my pre. My system is profiled in my system link. Which do you think would improve soundstage/imaging more:
Replace the P3? I'd consider used McCormack, or a passive line stage, but my amp clips at 5v, which is what my DAC puts out when using the XLR outputs, and I'd like to try those someday...not sure a passive is a good fit for my system? Plus I require a remote. That's a deal breaker.
Replace the Rotel RB-1080? I'd consider parasound (a21 is a bit too pricey for me), used McCormack, odyssey, maybe even older krell or classe. I want XLR inputs tho.
Budget is $900-$1200 for either. Music spans the full gamut, excluding hip hop and country. Room is small, 12x12x8. I'm going to throw up some affordable foam acoustic absorption this summer (foam factory). Thnx in advance.

One thing I forgot to mention is that you would certainly benefit from removing the electronics stack that is currently placed in between the speakers. *Anything* placed between the speakers will be subject to early reflection points and will tend to smear the sound. Try moving the electronics to a place behind your listening position or in the corner opposite the speakers....
Glai, so you suggest diffusing at the 1st reflection points? I always thought we want absorption??? I am also in a small space (10x11) so in my case should I use absorption or diffusion?
There are many things to create a more 3 dimensional stage. I think it would be a good thing to mention in an article how to make it more 3D.

At the end you Always will lsiten to all different parts togheter including the acoustic of your room.

An amp with a poor 3D image will not give a huge stage when you will change the reflections of your room.

I have been several times in room with many bass traps ( they spend a lot of money on it) and still have a poor sound.

The brands I did mention I sold for many years and compared to others to know whether it is 2 or 3 dimensional.

"Two things I would suggest.

Spread the speakers a little further apart, you have more real estate there to play with."

Actually, moving the speakers closer together frequently works better. I think it's audiophile nature to assume wider speaker positions equals better soundstage. Start with 4 feet and move out until you hit the sweet spot.

"Consider the purchase of a good tube amp. This alone will give you more body and 3 dimensional sound over the Rotel amp."

Now, that I agree with.
