PL EVO 400 integrated amp + Cornwall IV's = discovering music all over again. I'm streaming using the Amazon lossless HD service through Bluesound Node 2i. Led Zeppelin IV remastered last night - it was like the first time I ever heard the album. My first Klipsch KLF 20's from 1997 were a great investment at the time - but trading them in on the Cornwall's made it easier to justify this new amp. Perfect match.
I'm using this with a home theater, Yamaha RX-A2020 AVR preouts to the PL. Using HT bypass, I first had a ground-loop problem. Used an iso-transformer on the DTV coax at the wall - and 100% cleaned up the low frequency buzz. Watched Hamilton last night, and it felt like we were in the audience.
Now I'll be researching a new sub - that can be used LFE for Home Theater from the Yamaha, and RCA from the PL for music. I'll watch for ideas here.
