Teo Audio folks would admit their products reflect a continuous stream of ongoing development. I can’t keep up with their varied products. What’s listed on their website undoubtedly reflects some of those products. But then came GC, GC2, Ultra, Kronon and others, followed by the GC-JR and the double double series. And now their XLR balanced IC’s, which are surely a bargain, given their new 3-D printed connectors.
The point is that these guys don’t really answer to a Board of Directors or a Marketing Czar. Contact them and ask them what you want for IC’s, in terms of materials, connectors, length and implementation. They will undoubtedly try their best to give you an abbreviated matrix of prices for your objectives.
