Gig Harbor Audio carries the Sugden line. Might be worth a call to see if they can assist.
Audition of a Sugden in the Seattle area
I have been trying to find a used Sugden A21SE for a while now and not having much luck. No way to audition one as the only dealer in my area does not offer this.
If someone in the Seattle area has a A21SE I would be willing to compensate for your time to do a quick A/B to my current integrated and to see how it pairs with my system/speakers.
