Well I have had the Pliniusa-250,, the B&W 801#3 and am familiar with the Rowland 8's.
I ran my 801's with a krell ksa250, too polite.
The Rowland 8 might be on the Warm side. Plinius might be a tad brighter.
I don't think you could go wrong with either,
Love that rowland. 801's need good control of the lows
Too bad you cant get both amps and Sell the one that isn't to your liking.
