Furutech NCF sockets

Amps or other components powered on into the socket.

I have only just discovered that the less exciting sound is very likely to have been by a transit bolt left in the 552 upon installation. (My brother in law can’t follow simple instructions)

I will update once I have some new speakers in.

How did it turn out? Is the bass still soft as in a bit lean or soft attack.

Do you have an additional standard switched socket on the wall to compare with this Furutech NCF socket? If yes perhaps you can do some long - term comparison, listening on the standard switched socket for few days or weeks, switch to the Furutech socket and then go back to the standard switched socket after that to ascertain the differences in sound quality.

I’m interested to know if the differences are noticeably appreciable or negligible.

That is a law of nature.

So in Nov 2022 your brother-in-law said, “Yes, I’ve taken out the transit bolt and put it in your jamjar of hifi odds and ends”, but he hadn’t?

How long did it take you to discover this and how did you discover it?

Yes when my brother in law and I were installing the 552 I was holding it and I asked him to unscrew all the white transit bolts. I should have paid attention to how many he unscrewed and put away. I cannot remember exactly how long but it was a number of weeks perhaps longer than a month. I remember speaking to my dealer thinking I’d received a sub optimal 552DR as I had owned one two years prior that sounded superb. I remember missing my NAC 52 at the time and regretted selling it. He assured me that it’s probably just a long warm up so as I was fiddling around with hifi tweaks one day I noticed a small white bolt head under the casing of the 552. I was annoyed and relieved at the same time.

I think the bolt in the 552 was contributing to the lacklustre sound however I still think the rhodium plated NCF socket took an age to burn in. This is the case with all NCF products from Furutech of which I have 4 in total.

Must have been a delight to unscrew it and bask in the glorious sound.

Indeed it was. Although I would still say there was a further improvement later on. The 500 series takes a long time to burn in.

My first 552DR was a used pre so I didnt experience burn in although the warm up still took some time.

But my brand new 552DR and relatively new 500DR which the previous owner barely used in 1 year of ownership took their sweet time to settle in.

The NAC 52/135s in comparison warm up quicker and don’t require as much attention in setup.

white???..all the ones here are black for 552, 555, S/L phono, Snaxo bmr; hopefully irc!

Indeed, yes, 552 does require setup attention v Olive kit. Recent threads have ignored this, while claiming NSC 332s and xtra combos sound better than 5 series.

They are white on my 552DR. This is the photo I sent my dealer at the time

I’ve missed out - not seen before - hope it now sounds good!

First the transit screws, then the logo.

@obsydian
Would be keen to hear how it turned out eventually.

Hi sorry it has been a long while since I installed the NCF socket, suffice to say it stayed in place and was a worthy tweak.
