I'm glad you're happy with the Pass amps, a good product.
For others in a similar position, I would strongly recommend also auditioning Coda amps. Legacy originally voiced their speakers with Coda amps (rebranded for Legacy) before they moved to their current line of class D amps.
For those that have made the comparison, Coda provides slightly better sound quality than Pass at a lower price. Or course, Pass does a great job marketing unlike Coda who does no marketing at all. Those marketing costs are passed on to the consumer.
Based on personal experience, IMHO, Legacy is by far the best value in USA made speakers.
