This amp set is fast insightful and bombastic, delivering the likes of the White Stripes with an enthusiasm that's rare at any price...

With their ultra-vivid and transparent midrange, sky-high build quality, good connectivity, and one of the most pleasing metal remotes we've seen, these Roksans are masterclass of amp design”
