Hello to all, this is my first post here. I?m considering building a pair of MLTL cabinets for a GPA 604-8H-III or perhaps a vintage Altec 604. Before I commit the time and money, I?d love to hear a set and was wondering if there is anyone in my area of the country who would allow me to visit for a listen? I?m in Ohio and understand that my request may be a challenging one. I?m intrigued by what I have read about them and appreciate the support from the few I?ve e-mailed about the design.
