@pindac You had mentioned..."A Local Audio Dealership is handling Jay's Audio, as said on another occasion, I am tempted to have a listen / comparison to my own CDT > DAC, but do not want to be a Tyre Kicker with the Businesses Time."
If you have a sincere interest in how the Jay's would sound and perform, I think the business would be delighted to let you listen to it. How else would ever know if you liked it or not. You might be surprised as to how much you like it and if so, you might share that positive experience with us on the forum and therefore generate more business for the business.
I think you should give it a try 
Best wishes,
Don
