About 2 year ago, I tried a linear power supply and a prototype DAC from Ryan and his Core Audio partner at the time, Ben from Mojo. Neither product met my expectations or that of other audiophile friends who heard them. I was able to get a refund but not before being accused verbally of having opened up the units (thereby voiding the right of full money-back return).
Neither I nor my friends ever opened the units.
I sympathized with Glory's problems with Core Audio because he had recommended me to use Core's products, so to see him treated so badly left a very bad taste in my mouth.
That said, Ryan Mintz was always very helpful to me in terms of phone support and email support.
I only wished his products matched in practice his claims.
Moreover, I find perplexing the fact that months and months later, Core Audio only has 1 positive feedback comment on Audiogon. That makes me wonder how they are treating others.
Glory has hundreds of positive comments and not a single negative one. That should speak volumes.
What else do we have to go by on this site?
