I decided to order a Jot as well, and already got confirmation it shipped. I am very curious to see how it performs. I am going to build a balanced cable for the HD600s, since it seems easy enough, but wondering about one for the EL-8, thinking C3 Audio seems reasonable? Many reviews online have said that balanced is the way to go, and that it makes an audible difference. Wondering if anyone can explain why from a physical perspective? Just curious, since I can also find articles online that say that balanced supplies may be inferior to unbalanced. I am going to try both methods to see for myself, but wanted to see what others thought.
I do have another question though, how are people EQ-ing headphones. Do you have a dedicated EQ in line? I typically try to keep things mostly neutral, wanting to hear what the musician was trying to present, but can understand how some adjustment might be of value on occasion.
The choice between balanced and SE depends on the design of the amp, if it was designed to be used balanced then that is where the amp will perform best, and then there are amps like the Liquid Glass and a few others that I've heard that perform the same in balanced or SE.
I wouldn't spend the money just to get a balanced cable for the EL-8 since its very easy to drive and doesn't really benefit from running them balanced IMO based on my time with the Liquid Glass and Carbon, both of which can be used balanced or SE. I did build a cable for my EL-8 and originally had a XLR connector so that I could try them balanced on the two amps previously mentioned but upon finding no difference I removed the XLR jack and went with a 1/4" jack.
