Call it what you will, but when I have read Jtinn's comments over the years on gear I am familiar with, including the XV-1s, those comments have been very accurate. This applies to product he does and does NOT sell. Therefore Stan, now you know my answer to your question.
FWIW,I am doing a shootout right now of a XV-1s and a ZYX UNIverse, copper and silver versions. I will post my results soon if there is any interest in the results.
Now I've got to get back to my Marcel Marceau record.
Don't laugh, its great for testing background noise levels!
