You are a joker. It is the last thing I will do im my life .One pair of WBT connectors are priced as a hair dressing service in the USA. Blind theory is bad for audio.Some members here pay high prices for some capacitors with zero improvement in SQ.

Okay, you are right about me joking. But as much as you didn't like what I suggested to you, some others might have trouble being convinced to buy connectors they don't want. That they might learn from experience may not be enough to convince them either. If you don't believe in something, you might feel stupid for trying it, as one possibility.
 
OK, Mr. Wurzer. You should be more polite. I am not happy to waste my time with people who are listening to music on measuring equipment screens.
As I said , it is Do it Yourself audio forum . Some people belong to other forums.

Kamis, maybe things have not started off not very well, but I might agree with you to some extent. In the history of audio and as measurement technology has evolved, at times people who relied on what they could measure with a given technology later turned out to be wrong about what humans can hear. That being said, measurement technology has improved over time and gotten a lot better. At the same time, it is well known that people can believe they hear things that just aren't there. It's something similar to the placebo effect that is well known in medicine and affects all humans to some extent at times. So, we have limits to what we can measure, and limits to what we can hear, and history has shown that errors have occurred with both. So, wanting to measure, especially given the best measurements we can make today is not a bad idea at all.

How about a laugh - original on diyaudio!

"There's another benefit for using a fully differential amp. That is that both of the speaker wire connections are active voltage (as opposed to single-ended where the negative/black terminal is just ground). This means that you have two sides controlling the movement of the speaker itself. [] Using a differential amplifier will have more force on the magnet of the speaker because it's now a push/pull situation. A single-ended amp will be more "loose" in its ability to control the movement of the speaker."

Cracked me up!

And here I thought the differential amplifier was to put more stress on the power supply transformer thereby making a louder hum.

Gees I learn something new every day.
 
I guess I was confused some sellers list them as Neutrik/Rean. The main Neutrik site does not have mini's listed.

Ah, ok. Rean is a brand that's owned by Neutrik and produced in China. I think all Neutrik-branded stuff is made in Liechtenstein.

I much prefer the Reans to the Switchcraft (who first designed and patented the mini-XLR). Love the collet/chuck strain relief like that used on the Neutrik full size XLRs. All the other copies are knockoffs of the original Switchcraft.

One thing I don't like about them is the rubber boot with the tiny exit which can sometimes split depending on the size cable you push through it. When I used them for my aftermarket headphone cables for Audeze headphones, I would chuck the *** end into a cordless drill, spin them up and use a razor knife to slice off about an eighth inch from the end of the boot.

Those $3 mini XLR's with all the right bits are looking better and better every moment, eh? :D

Difficult when you want to take your gear to your friends house (assuming you have friends, of course) or they want to bring their gear to yours.

Other than that, Switchcraft made some mini XLRs back in what, the 1980s I think, that I liked very much. Seemed to have caught on like room heaters in the Amazon... airconditioners in the Arctic? :rolleyes:

Surface Noise Emulation Ultra - SNEU

So, in light of the need to be able to compare LP to digital sources in a fair way, I am in the testing phase now, and hope to be able to introduce in early spring 2017 the Surface Noise Emulator Ultra.

After significant testing and measurement it has been decided that the average level of the SNEU unit is -63.8dB. You will be able to both play this back via separate speakers (if you have the gear on hand), mix with the signal source AND importantly import the algorithm onto your computer and embed in copies of your digital files.

Now, for the first time you will be able to effectively compare LP and Digital on equal footing.

Interestingly enough blind testers have reported that when using the SNEU digital sources sound more "liquid" and "natural".

White papers coming from the research department soon.
