Any experiences with Modwright SWL9.0SE ???

Curious if anyone that has owned this preamp if they could shed some pros and cons on the Modwright. I am looking to introduce one with my B&K 200.7 reference power amp and my Pioneer Elite VSX94tx Surround Sound Processor. My SS amp gives out 200 / 375 wpc into 8/4 ohm and I am looking to make my speakers sing a bit more than my SSP allows. Although my speakers are 4ohm Tyler Woodmere II's I was hoping that a Modwright tube preamp would do just that.

Let me hear the news...good or bad
