Barrelchief, as of now, mono versions are only available by purchasing the boxed set. Originally limited to 10,000 sets in the USA, now supposedly issuing 50,000 mono boxed sets.
Given that the MONOS seem to be in hot demand and are generally regarded as "better" - what is the chance that the public reaction might cause Recording Labels to actually sit up and take notice???
Here we have a contest between the latest and greatest stereo brick wall limited compression "loud" mastering techniques (state of the art for 2009 and done extremely well - i.e. just the "right" amount of compression according to modern standards) and the old tube based mastering consoles and mono recordings of the 60's??
Would it not be funny if Record Labels discover that people prefer the more natural uncompressed sound of the older material - even in MONO!!!
It would be a revelation, a massive eye opener to the industry if 60's MONO is competitive and judged by many to be BETTER sounding than modern "State of the Art" loud hot compression!
