Audiobroke is correct in that I have not heard that particular Parasound combination, but I did own a Parasound PLC1100 preamp and model 1200 - 250 WPC power amp combo (both John Curl designed) several years ago. Krell gear is simply superior for driving my Thiels with superior resolution and detail retreival not to mention a much better current capacity doubling down to 2 Ohms. Parasound gear is not rated at 2 Ohms.
If you don't need this current capability then Parasound may well fit your needs. Also the same goes for Bryston; I had the BP25 preamp and 4BST and later 7BST monoblocks.
Just got a Krell 400xi to replace my Musical Fidelity A5 integrated and have been holding onto the A5 to make sure the Krell is superior for the second system Thiel 2.4 and, after two weeks of A/B comparing, it certainly is. More depth, detail, superior imaging and certainly better extension top and bottom. Sweet and solid, I couldn't ask for more.
I have heard the JC1 monoblocks and these are very impressive pieces.
