Threshold Amp and Sonic Frontiers Pre? HELP

I have a Sonic Frontiers SFL-1 with a Mullard tube and I am considering an amp upgrade to a Threshold S/200 Stasis. I wondering if any of you guys have expirience with SF and Threshold. I've been very happy with a tube pre SS amp combo thus far but I know that a Nelson Pass Amp will give a lot more to my speakers than my BK-ST140.

That being said, I love the BK-ST140. Maybe one of you will convince me to keep it in? I don't know. Any thoughts on that amp with the rest of my system?

I am using a pair of Theil cs1.5 speakers and a Monarchy Audio 18b Delux DAC connected to my computer. I'm using Audioquest Coral IC's and Audioquest Gibraltar speaker cables.

Thanks so much for any thoughts or ideas.

Elevick, the Threshold S200 will actually paly louder than the B&K ST140. The B&K really isn't up to handling the impedance load of those Thiels. Th input impedance will on the Threshold should be a bit better with the SF than the B&K too.

I've owned a B&K ST 140 and ran it with Thiel CS 2's which were a much easier load than the Thiel 1.5's. The B&K ST 140 is not a great match with low impedance loads.

The Threshold is only rated at 5 Watts less per channel than the B&K into 8 Ohms, but below 8 Ohms the Threshold is much more capable. Oh yeah, and IMHO much better sounding.
