Solid state - How wide can 3D image go

soundstaging is much more about your room acoustics (size, shape, control of reflective surfaces), speaker set-up, and the elimination of distortion than media types. certainly source electronics are also involved. the idea is that when system set-up is right, the music ceases to be heard as coming from speakers, it comes alive in your room. bad acoustics and poor speaker set-up and distortion (non-musical noises) localizes the music as coming directly from the drivers instead of being holographic.

and the best systems allow each recording to have a unique presentation for that recording as far as soundstage characteristics. if every recording has the same soundstage, that is not musical truth.

sure; tubes do bloom more than some solid state, but the overall system is more significant than the circuit design.

in my room with almost all solid state gear, i can get 180 degree wrap around soundstaging with the right CD files. even behind me to the sides with out of phase information on some recordings.

or......in a poor room with poor speaker set-up, the best soundstaging recordings or media (or tube gear) can be limited to between the speakers.

it’s about a good room and the care of system set-up mostly.....not even level of investment (or tubes in and of themselves) is that important to width of soundstage.

I agree that the room and placement is important, but digital equipment can definitely affect your soundstage. A key technical feature of a good streamer is low jitter, with negative results being a poorly defined or smeared image. The DAC you are using certainly figures into the equation as well. Can you provide some details on what you using for streaming and DAC?
