I really thought the intent of this site was to discuss possible audio improvements.
In reality, it is littered with too much veiled antagonism and abuse.
I purchase improvements after careful research and consideration, usually observe a difference and truthfully pass my observations on, whether favourable or not.
I appreciate the comments from those who have tried products, haven’t observed any difference, and report this.
I won’t lecture you on how to live your life, and I wish others would do the same.
