Plangent technology uses (IIRC) the bias signal to remove wow & flutter on old tapes. Downloads of the hallowed Cornell show from the Betty board should be out soon, tho the discs are sold out.
I've heard the better Rogue amps when auditioning 3.7i Maggie speakers and they sounded nice, tho I did not compare them with other amps.
I have an ARC LS-25 Mk II pre with a Sunfire amp. I may audition the Benchmark amp to see if it sounds much better. I am likely to stay with a SS amp and tube pre - there is an entire thread on here about amps for Magneplanars (my speaker choice). I can post my short list form that thread if you want. LMK
