I had Symphonic Line Mono 400 amps, they made the music seem effortless. I sold my SL gear around 2009. I'm pretty sure I had an RG7 for my center channel in my HT system as well, Klaus's memory may be better than mine.
I only had amps and (still have) a SL cartridge in my tonearm, no pre-amp; cdp; turntable etc..
About as high end as high end gets.
