The reason I asked you that question is that Avalon distributor in Hong Kong told me the same thing that Rowland and Cardas are the best match for Avalon. I am living in Shanghai and had to buy Avalon through my HK distributor. I am using Krell Evo 400 monoblocks and Audioquest Everest speaker cables. I have no problem with this set up, but just don't know how different or whether they are better with Rowland/Cardas.
Yes, I love the Avalon speakers. There is really nothing like them out in the marketplace. Had B&W 801 Nautilus before and was thinking about upgrading to the Diamond series until I demoed at Avalon dealer in Hong Kong. Could not believe how sweet and musical they sounded, with an incredible transparency and sound stage. Felt like I was totally wrapped in music....
