Willems - I have to say you should find the Audiogon thread "Preamp Deal of the Century" and read it. That thread will point you to a fantastic preamp which may transform your system. The base model is the Syrah and it sells for 2.5K new. Older versions of the Syrah had a few growing pains as it evolved in regard to hum and quality control but the latest batch of Suprateks seem to be rock solid.
For 2.5K ---> 5K, you will not find a better sounding preamp.
A passive preamp is not going to help you with harshness.
With the right tubes & the Syrah, your system will sound less harsh, liquid, dynamic and much more natural. The Surpatek is not a warm sounding tube preamp so it will not impart warmth in exchange for the harshness.
Supratek's tend to sound good regardless of amp but if you must buy an amp too, then take the remaining $$ and get yourself a pair of LAMM M1.1
