Per Bo..."These days I only focus and sell a 3 Dimensional sound. Most 2 dimensional products I only use to let my clients understand the difference in stage between them. It is very easy to make people understand why it is superior."
Yeah, I guess all you got to do is look at the specification in the manual that says whether the component is 2 Dimensional or 3 Dimensional. Its that easy.
Problem is no such specification exists. It all a matter of subjective opinion based on listening and in Bo's case, he prefers to listen and recommend the product lines he sells!
He is an audio salesman Kalbi23 and I suggest you be careful taking any advice from him. Marantz and Arcam are very fine, good sounding products even though Bo "thinks" they are 2 Dimensional. Remember there is no measured or written specification called Dimensionality to prove this - only what's in Bo's mind.
