WTB: Sonic Frontiers SFM-160 mono or power 3mono

I'm looking for power amp SFM-160 or power3 mono of sonic frontiers. I know it's very hard to find one now but i'm very in love with the deep sound bass and warm of them to drive my 87db in 4ohms Dynaudio S5.4
If anyone sell please pm me or any advise something like this power?
Hi. I just joined Audiogon because your thread came up on a google search. I have two SFM-160's that I'm looking to sell. If you're interested, please email me at mattintaiwan@hotmail.com I live in the San Francisco Bay Area and would be willing to ship.
