Well, I've had a couple hours now to get familiar with Boz's Imperial Delay, and I gotta say it's pretty durn slick.
300 bucks' worth of slick, dunno yet. That's more than double the list price of FabFilter Timeless2 ($144) and way more than other complex full-featured delays (e.g. U-He MFM2 $79), even higher than the premium classic Echo Boy from SoundToys ($179).
Clearly, it's not positioned to compete with the likes of the HorNet delay, but that's not a fair comparison since low-cost delays offer only basic functionality. Imperial Delay is definitely high-end in terms of features. So far, I can list on one finger what I've found to be missing, and that's the ability to type in precise values - not a deal-killer by any means.
In terms of ease-of-use and quickness to set up, it's not quite up there with the Sonitus Delay but it's not at all difficult to use. A few knobs aren't immediately obvious, e.g. "Smear" and "Dynamic Feedback" but they're worth the effort to figure out. The most important settings (e.g. sync, tempo, and mode) are clear and simple. I can see this being my go-to delay for when fancy Timeless2-style modulation isn't needed.
Hopefully, they'll re-think the price point and put it under a hundred bucks. Leaving it at the introductory price of $59 would be even better, and almost guarantee a hit. At $50, Boz could do for delays was Sean Costello did for reverbs, making it a must-have plugin. Yeh, it's really that good.
