Biggest Sonic Improvement


What is the biggest sonic improvement you have ever made to your audio system. Mine was a surprise to me. I replaced my Audioquest PT6 tonearm on my VPI turntable with a VPI JMW Memorial tonearm. The improvement in the sound nearly knocked me off my feet. I never realized a tonearm coud make that much difference in sound. How about some of you guys, what has your most exciting improvement been.

LISTEN UP, B&W OWNERS: you bought some really nice 801's or 802's, and you love the way they sound. Now, if you want to hear how good they can really sound, go to the web site of North Creek Music and buy their replacement crossovers. You don't know how much better your speakers can sound, but I do, because I just bought some for my 802's. WOW! Rest of my system: Cal ICON MkII Power Boss, CD player, Bryston BP-25 preamp, BAT VK-200 power amp, lots of expensive wire. The music is trapped inside those crappy B&W Xovers, just waiting to get out. Set the music free with North Creek Music mods. Simply incredible.
When I switched my speaker cables from Kimber 4TC to 1999 MIT Shotgun High End series cables. The sound opened up dramatically in all areas ! Depth and width of soundstage improved greatly . The 4TC was flat in comparison. Detail ,bass,treble and mids opened up tremendously.Day and night comparison !
when I started to listen to sota PCs. King cobra or FIM power cords are the best upgrade I have experienced. I never would have thought this. Hearing is believing.
I recently moved my gear from a room that was 16 feet wide by 18 feet long 8 foot ceiling to a room that is 18 feet wide by 15 feet with a cathedral celing 10 feet up to 18 feet.I could of spent 5k more in the other room and not achieved the same sonic improvment.
