During the last trip abroad (Zurrich, Switzerland) a few weeks ago, I had a nice opportunity to witness a shootout between Rowland Model 625 and Bladelius Ymer power amps at friend's appartment.. Line up was consisted of Krell Evo-202 preamplifier, big Avalon speakers and Wadia CDP, various cables tested, mostly Transparent and Cardas etc.
I'd say that Bladelius Ymer stole the show... Brilliant performer! Big bass, sugar coated mids, crisp highs, all-aluminum impressive appearance. Model 625 sounded a bit leaner, colder, perhaps a bit more neutral in mids, but was truly beautiful chunk of metal work. Arguably the most beautiful piece of electronics I've ever seen!
I've been told that Model 625 is significantly more expensive than Bladelius amp... Based on what I heard, the Ymer power amp emerged better purchase, pricewise and soundwise.
