It's a high detailed photoreal Tube Amplifer, McIntosh 275 50th Anniversary Edition
You can use Max 2010~2013 for rendering with Maxwell render and V-Ray.
You can also use FBX, OBJ or STL formats for Polygonal tools
and 3DM, IGS or SAT for Nurbs modeler like Rhino.
Nurbs file has very big size, but it's due to a 'Tube Case' object which you can see in a preview image.
So if you remove it, file size decreased reasonably.
In case of FBX, there are two version included. (normal & triangulated version)
In .Max and .3DM file, there are the same named layers embeded.
So if you need more subdivided mesh for some parts, you can easily change it from original Nurbs model.
In my case, I used 3DM->FBX->3dsMax converting process.
Object / Polygon / Vertex count is (case of 3ds Max file)
8 textures and a HDRI is included with Studio Lighting Setup.
Texture size is from 314x512(for tube) to 2443x600(for base model)
