I wonder how the Pass INT-250 compares with the Gryphon Diablo 300. The Diablo has glowing reviews, but I haven't seen any comparisons online.
One of comments after the INT-250 TAS review says, "Mr. Neil...your last sentence clearly points that you have not had the chance to hear The Gryphon Diablo 300..."
