Log Home / Listening Room design

I recently moved into a log home,  I am struck by how quiet it is.  This is in large part to the fact that the logs used for the main structure are made of old growth yellow cedar from BC with 18"-22" diameters.  Also the logs are hand peeled and fully scribed meaning that each log is carved specifically to sit directly atop the log below.  This, done correctly, can make a log home very tight; particularly as the wood dries and shrinks making everything even tighter.  This type of construction doesn't require any "chinking" (putty for lack of a better description) to seal the openings between logs, because there aren't any.  The home really doesn't have a room that is conducive for a listening room, therefore I am planning to build a dedicated listening room on the property.  My question is this.  Should I build my new room structure from logs similar in size (15"-20" diameter) and with the same construction methods that where used on the main home or should I build a room with the traditional "stick-built" construction methods?  The log home route intrigues me most because I would think that the natural diffusors that are created by stacking round logs, hand peeled and fully scribed to form a wall might naturally remove some traditionally bad room characteristics, like slap, from the equation.  This scenario is a bit risky because so much clearly depends on the craftsmanship of this room.  It could suck or it could be great.  The room would still need to be treated properly with appropriate absorption material and the floors and ceiling will be appropriately treated as well.  If I go traditional stick built, especially if I build a room in a room with a couple inch air gap and appropriate treatment, green clue, duel layers of drywall, I am almost assured of being able to deal with any odd room characteristics and have a perfectly good room.  Both rooms would be rectangles, the same size: 10'H x 24'L x 16'W.   Anyone have any experience in this situation or advice on which direction is most desirable?  Thanks in advance.
