Luxman 505uXlI vs Cary SLI-100

No to tubes. My pick, Luxman.

@maholl50,
When you acquired the SLI-100 with KT150s, do you have a copy of the build-receipt or recall if any special upgrades were done at original purchase time? i.e. a friend was the designer of that SLI-100, originally. He shared some nice upgrade tips on all of my former Cary amps, with some surprising results.

Having owned and heard several different Cary amps with before/after optional [or local-tech custom] upgrades, it can be a really nice uplift. Worth investigating if you are trying to decide what to keep. 

I am wondering what I could do to my Cary SLI-80 acquired in 2003. The only upgrade I made some time ago were Jensen PIO .22uf coupling caps. Before that, we tried VCaps for a year and eventually replaced them with Jensens.  

I agree with a few others here---Luxman and Klipsch. I have the 505uxii paired with some Tekton Lore References. You can't go wrong with Luxman. Keep us posted.

You have the amps and speakers, the room, presumably the music, but want strangers on the internet to choose the combo that sounds best? This couldn't make any less sense.
