    • skunk stripe? what up wit dat? Never seen it on any other pair. It can't be cleaned/removed?
    • The last two LPs I listened to was Karla Bonoff and Norman Blake.
    • He might be serious about TS, ya know.
    • Still available for local pickup... If no interest by early next week, the crossovers may be flying to a new owner...
    • Yes.....  it still sucks  lol  (although them ABBA gals sure could sing!)  
    • Guys, Thanks for the encouraging feedback. Yeah, I have several Receivers scattered around the house. Now I will shuffle the Optimus and other speakers to their most appropriate locations. I am a bit of a "Pack Rat", so I keep everything, including stuff that is 30+ years old. 🤪 I hate throwing something that is perfectly functional in a land fill, and very few people want "Old Technology" these days. (including me), so it is difficult to find it a "Good Home".  We have a yard sale coming up, maybe I can unload a few items there, but last time people wouldn't even take old flat screens priced at $10. I'll keep you updated if/when things progress ...
    • It was just a thought. I haven't touch a Mac since 2016. I was looking up the specs, and it looks like a no on that idea.   Might try a DAC, or other piece to go between.
    • Oh I should mention setup.  PC connected to Anthem MRX720, power from a pair of VTV Hypex NC1200 monoblocks.
    • ... a few moments later...   I am super impressed with the KI-396, and overwhelmed by the encompassing live-like sound these can output.  Even before running ARC, I had a smile on my face and after running ARC the smile is even larger.  Coming from a pair of electrostats that gave me some trouble over the past almost 20 years of ownership, these are a real treat and check many of the boxes.  It also helps that they are nowhere near as fragile.    Here is one channel of result of running ARC (red is sweep, green is correction, black line is target curve).  I can always tinker with this later.     Only complaint and this may go away with time (not sure) is the skunk stripe down the foam backing on the grill.  If it still bothers me with time I'll replace it with something less "shiny."  Worse in person than it is in the photo, but a reminder these are pro-level cabinets.     cheers all!  
    • Been awhile since they did that. I think '12 was the last year but?????
