I think you are right on track here with CJ and Shindo. If I had the space and money I would really like to build a system around Shindo… the descriptions have always been intriguing to me and in line with my desired aesthetic, but so far off from where I was, I could never go there. But from what you have said… on target for you.
Also, I have lived in Japan for a couple years. I really love Japan and the Japanese, their reverence for really fine craftsmanship, nuance and iterative improvement has got to have created the magic of Shindo… not for rock and roll… but for a completely zen wholistic recreation of music. I am jealous of your objectives… I really hope you go this route… but you will have to go speakers as well. If you do, I’d love to hear it.
