Gentlemen, There are many differences in the way the cables are made with these two companies. They both do believe in using networks however that is where the similarities end. There are reasons to use networks on wires since all cables operate as filters. How this is done is different with Transparent and MIT. I can't speak for what Spectral is doing these days since I have not been a dealer for quite a while and I had my issues with the way they try to control everything that a dealer does.
Transparent does not use multigage wires which MIT does. Transparent calibrates the cable by length and by component which is not the case with MIT.
I know there are a few more differences however I am not technical enough to explain them they both make quality products and like many things in audio they are certainly system dependent.
Edorr be careful what you do the Spectral folks can be less than tolerant of the non believers, a word to the wise.
In my own experience there is significant differences in these two companies particularly when using tube gear. I dont care for the MIT at all and I think the transparent works really well.
Thanks for weighing in Elliot. I have no intent to even inquire about this with Spectral, because the response is entirely predictable. However, if I can get some confirmation from actual users Transparent can be mated with Spectral with good results I would feel comfortable enough to pick up a 260 or pair of 360s if they show up at a good price.
