My experience with Fritz speakers is that he, like me, makes mellow and laid back speakers, especially in the mid-treble regions. I like it a lot and find it very natural and easy to listen to for long periods of time.
The challenge however is a dark to mellow amp may be too dark, and that's kind of where I hear a lot of Parasound amps, and ICEpower Class D, both of which I've owned and have a positive impression of.
I guess it's , yes Parasound is very good but is there an inexpensive amp that will give you a little more color?
