No experience myself, but you might consider these comments by someone who's words I trust (Viber7).
Soulution 511 + 520 -- This is an exquisite pairing and is both very transparent and very resolving although not quite to the level of the Element 118. This combo is a touch warm relative to the Element 118. No amp was as fast as the Element 118 although I would not consider the Soulution slow by any means. In fact, directly compared against anything from Pass Labs and a Luxman M-900u, I found the Soulution (both a 711 and 501) to easily outpace those amps.
