Ref 160M MkII?
 

New MkII version of 160M said to be coming soon but I could find no details. No updates on 320M either and it was announced almost a year ago. Anyone know details?

Answer to question per dealer.

I spoke to Trent at Audio Research ,the upgrade essentially is the replacement of 8 power supply filter caps and upgrade of input wiring. This is a crossover technology from the new 300 watt amplifier. This upgrade made a significant difference in the performance of the 160M’s but didn’t translate to the 160S. Great if you own 160M’s but not so much for the stereo amplifiers

This sounds like an upgrade that ARC can make with existing (Mk 1) 160M units.

Yes that’s what dealer said but was not confirmed with Trent or ARC,
