Teo Audio is located in my city (Kingston, ON). Ken Hotte is a straight up guy who is incredibly knowledgeable and, more importantly, very curious. He’s also a very nice guy, to boot!
I first tried his Game Changer IC last year, figuring I couldn’t go wrong with his money back guarantee. Prior to trying Tea Audio's cables, the most I had ever spent on a cable was $250. So this was a big upgrade for me.
I was blown away by the difference his IC’s made. I would echo bugredmachine’s review comments. Since then I have added another pair to my system.
FWIW, my system consists of:
Amp: Golden Tube Audio SE-40 Special Edition monoblocks (modded)
Pre: Don Sachs custom 6SN7
Turntable: Roksan Xerxes
Tonearm: Rega RB300 (w/Incognito wire, Audio Origami SOFC external cable, Michell technoweight)
Phono Cartridge: Decca London Super Gold
Phono Stage: Croft RIAA
CD/SACD: Esoteric DV-50S
DAC: Teac UD-501
Digital: Asus VivoPC (headless PC running JRiver MC21)
Speakers: Martin Logan Spire
Speaker Cable: Grant Fidelity SPC-2.5 5n Copper
