my system is so much better than i ever dreamed when i started this journey about 30 years ago.never did i think i would be possible to achieve the sound, i currently hear, in my listening room.My amps are superb...the speakers are amazing...the network player sounds better than the SACD player that preceeded it.I have 2 Silent Source 'Music Reference' power cords.My new Silversmith 'Fidelium' speaker cables are truly amazing.The addition of the Uptown Audio 'EtheREGEN has significantly improved the sound.The addition of the Salon ethernet  cable has improved the sonics.I changed my previous modem/router setup to a single Actiontec product.Have just added 2 REL 212 SE subwoofers. The addition has significantly improved the soundstage and midrange....as well as the bass.I have recently replaced the Symposium Platforms that were under my speakers..Tidal and RELs, with AV RoomServive EVP HDR isolation devices that have significantly improved the sound.Upgrading my Lumin to X1 level was a great idea.....Have replaced the Psvane WE 300B tubes with Psvane ACME 300B tubes.My 845s are Psvane WEs.Have also added a LessLoss Entropic C-MARC power cord to my Lumin X1.Have also added a LessLoss C-MARC RCA interconnect..Stay tuned..
