The ST-14 is pretty much sold out at this point. We do have a limited quantity of the ST14.5 coming soon; once they are built they will be sold at a discount from the ST-15 the only big difference is that is lacks the resonance enhancements of the ST-15.
Time to time I will be up-grading users from the ST-14 to the ST-15 and therefore will have used versions. Please let me know directly, john-at-masterhap-dot-com , if you are interested in a used version and which one. I will then add you to the queue and keep you posted on availability.
I know it is a little bit confusing at this point but bear with me as it is not easy for me to keep all the balls in the air. The good news is that all of this is slowly becoming managable and all processes are improving.
I will add here that although the ST-15 requires a significant investment it is worth the wait and I would really appreciate your support.
