Hawk,
You are welcome. My speakers are Silverline SR17.5. I replaced the stock crossover capacitor with Mundorf Silver/Gold/Oil. I replaced the stock resistor with a Mundorf Supreme. However, within about a week (I've already received shipping notification) I'm going to replace the Mundorf caps and resistors with Duelund VSF. I'm looking for less top-end emphasis than what the Mundorfs seem to be doing. I'm expecting the Duelund to be better balanced.
Anyway, back to the Rogues. The guys that own the local shop here are Rogue dealers. They were up last week to listen to my system before I changed the crossover... they want to be able to compare the change.... and they commented how much they liked the M150s over the M120s when the 150s came out... the improvement was immediately apparent... and they both said that as big a jump as the M150 was over the M120, the M180 was that big of a jump over the M150s yet again. We haven't done a M180/M150 side-by-side. Someday I may take my amps by the shop and we will. But don't get me wrong... I have heard the M150s many, many times in the shop and they are quite nice!
Also, my interconnects are Kimber select, and my speaker cables are Kimber Select KS-3035. My source is a Rega Saturn CD player.
I may have missed it in your earlier post, and if so I apologize, but what components other than the Rogues and Primalunas are you considering? What speakers, source, wire? I'm just curious.
