I'm using a Sugden A25B on my Altec 620 and it's quite a good little amp. Musical and warm sounding but not the final word in definition and clarity... I didn't listen to the Sugden you mentionned but it's most certainly good... I've heard other Sugden products and they all sounded good... Is it as good as the Pass Lab ? I can't tell since I never had the chance to listen to one... Sugden products are not known in the US but many audiophiles are using it in Canada...
