No not at all. I think you will get better bass results and better overall performance. I'm not talking about playing your system loud. Just better performance in the midrange and bass.
My Vienna Acoustics Haydn (Home Theater) are powered by Musical Fidelity A300cr. That's a good comparison to the Hawks or Model 1's with the Plinius 9200.
The A300 is rated at 225 watts (8 ohms) or about 40A.
Make a good choice on the IC's and speaker cabling and you should be set.
