Do you happen to know if the Crown XTi 1000 is in the class as the D-75A, as far as transparency, quality, etc.?
I wish I could answer that definitively, but I can't. Some Class D topologies are extremely transparent and linear, but others are much less so. Crown has expanded their product line downward in price over the years, and I have no experience with the newest or least expensive models. I do know that at least one of their Class D professional product lines produces substantially different responses above ~14kHz with different speaker loads. Unfortunately, it appears that they have largely abandoned Class A/B designs.
