I had the Watt/Puppies 5.1's and ran them with the Krell KRC-HR and FPB300, then FPB-600 (far superior to 300) with Transparent Reference. I now have the MAXX with KPS-25SC and 650MC's and CAST by Transparent and Transparent Reference XL speaker cables. I think Wilson designed these speakers around Krell, Levinson, etc with Transparent cabling, so you have good synergy now. A good Krell amp would make them come alive.
What to match with Watt Puppy 5's
I've just purchaced the speakers of my dreams. It may seem small to some, but this is what i've worked for a long time coming. I currently have a Krell HTS2 and a Krell 280 CD. I am also running transparent cabling. What amp should I consider? This is in a Listening/theater environment. I enjoy all types of music from jazz to classical to rock.
