Cables with BNC Connectors/Adapters Are Generating A Superoir SQ

Thanks again Peter, those are great news!

Hi Stanley,

Are you sure that there's an *extra* network involved when using RCA ? I mean, usually itis the other way around.

or

Or you have a fully differential amplifier and internally RCA turns into balanced again and then you are correct (extra network for RCA).

In the latter case it is hard to predict but that network is then for the good cause because it will sustain your amp's internal differential working; always better than shut off half (which I think won't even be possible).
Although this is a bit unrelated to the work out of BNC vs XLR, BNC will be the better one because of other properties. Only cancellation of (picked up) noise will not be there (but I don't have that either).
One thing, the opamp most probably involved indeed won't be for the better. No idea whether you will notice against the new cable.

When it is the other way around - and your (real) balanced input turns into Single Ended internal operation, then BNC will be for the better because of the further (better) properties. For RCA probably not (but this is a moot thing). So here it now will only be about the cancellation of (picked up) noise.
So this part is the same for both situations.

I must agree - not easy to determine in advance when your idea about this network is correct. Sorry ...

Peter

Thanks Peter,

As far as I can see (understand) my amps are fully differential.

Please see this (Italian) article: http://www.audiocostruzioni.com/r_s/ampli/amplificatori/audioanalogue-maestro-200-monoblock/audio-analogue-maestro-200-monoblock.htm.

On the 5th and 6th photo you can see the structure of the monoblocks and on the 4th photo you can see the input terminals. On the right hand side to the XLR input are 2 RCA's. The rightmost RCA is the "positive IN" and the left RCA is the "negative IN".

The manual adds: "The connection may be either balanced or unbalanced. If you choose an unbalanced connection, the connector of the other phase may be left open or connected to a 600 ohm impedance termination". Using balanced connection results into a better noise/sound ratio.

I guess it will be a matter of trying out. The worst thing that can happen is that I will have to change back the BNC's for the XLR's on the NOS1a.

Yeah, well,

As said, I can keep on "trying" (or trialling) forever, but in your case Stanley, your amp is 100% ready for what everybody with balanced may want : Balanced BNC connections.


So, just use the two now still RCA connections (which will be turned into BNC connections). What freak of an Italian has sorted out *that* ...

Too bad (for the $$) that you will need 2 pairs of Blaxius'.
But I can imagine that the manufacturer gives discount on the 2nd pair ? Next though you might lose the gain on that on the double adjustments. So 2x BNC in your NOS1(then a) anc 2x BNC per mono block.
But what you gain again is 6dB of output. So easy choice. Hahaha.

uhm ...

Peter, have you seen my email about the 75B upgrade?

Hi there Juan,

Yes I did. But I don't like to over and over again answer the same questions. Additionally I said (in the topic) that I won't allow people to send in their NOS1(a)'s *again*. So no need to ask (and also no need to say you missed that because it is clear now).

Please allow me to put it like this (and don't get sad or something) :
This, what I call "a stupid thing for the better" has cost me I don't know how many too many hours. And now I don't like to spend anything else which is unnecessary.
And for others (too) : "there is no electronics shop in my village with 1000 citizens only" is an argument I don't even think of responding to because then you drive 100Km or whatever it takes. I know this is a bit dangerous to say this, but I think like this and when asked I must talk about it (email).

I rather get "spiritually enspired" by Vinly Rig subjects; I say this in order to show Mani (but in the end you all) that I don't think that *that* is a waste of time because nothing tells me I am 100% correct (so I try to learn with each word I even write myself). May count the same for the electronics shop and whatever people may find more easy (just send it to us here) but I feel that I can decide for that. Plus - and I can't emphasize this enough - I won't allow myself to even feel the slightest responsible for something I asked money for and which does not work. I just can't. So send it in *again* to undo all ? and ask money for that now ?? NO.

As said, don't feel sad because this is just me and my own thinking !
Best regards !

Maybe I must correct something. *Of course* I suggested that it is Juan in this small village etc. But this is not him ...

That´s fine Peter, clarification accepted along with the implicit apology.

Something else ...

In the past few weeks I haven't been able to really listen to / enjoy my own "Blaxius setup" because of all the trialling, but the past week I finally could. And since I'm a bit out of the "5 days and check all there is to check for" I am finally just playing music which pops up in my mind for the mood I have etc.;

Maybe I didn't express so much (or didn't really emphasize) how super "real" and live all now sounds (also vagened by my own in-between reports about different (impedance etc.) setups, but here I have one which was a big surprise to myself :

Once in a while I play Autobahn (that stupid 23 minutes or so track from Kraftwerk) and maybe one time I told about it how that is so superb relative to how I knew it from my young years.
Might you know it (OK, who does not), this is actually a sort of strange brainwashing "song" about totally nothing. Maybe that's why I bring up the brainwashing. But for example, when we play it (say 1-2 times per year) we already start laughing at watch our son Paul because at the very first time we played it I had to explain that this track is great of its stupidity. So at a second time of playing it we started to count the different sentences sung (merely sproken) throughout that whole 23 and I forgot but if it's 5 it is many.

So yesterday too I put it up, pointed the partner in crime to Paul to see his response (you know that guy always with headphones on behind his games), and yes, at the very first tones he expressed a "toooo-tooot" to announce he recognized it (with in mind this horn blowing which is super fake from the synthesizer's early era sound).

So far so good.

What happened after that is hard to describe, but starting at the end I noticed in aftermath that I never heard any of those 5 different sentences (a dozen times repeated) because ...

I - and not only me, was dazzled from the totally sucking in harmonical expressions from all those differently combined synthesizer sound and of which I in the end said - wow, maybe we now must look more for analogue synthesizers (and early ones ?) because what *those* are capable of ... ?!?

So this was 23 minutes long complete amazement of a million things in that track I never heard one glimps of ever in my life. So no matter LP or all the digital setups I used previously (mind you, time span of 44 years or so that the album exists), it has always been a kind of one-finger keypresses on a cheap keyboard which stupidity was explicitly supported by the literal stupid texts without content (but from real life though) which for me made it this actually a product of art.

Was I wrong.

What all happens in there suddenly comes across as so intelligently done that while listening I started to wonder how such an early synthesizer could do it without a year of work of preparation (while at first glance (of OK 44 years) it seems a Sunday afternoon recording). Maybe it *was* all accidental and possibly the guys from Kraftwerk never heard it like this themselves, but what al not can be in a recording, waiting 44 years to be digged out.

Right, after writing this I guess I am going to sort out how this was produced.

Peter

PS: Last time I played this was before the Blaxius but for almost sure with the NOS1a. However, this can be compared to Get Ready (Rare Earth) I reported about in this topic, and which was from the Blaxius (pretty sure) and which also 20+ minute track is a bit the same as Autobahn. From the same era and almost as stupid. What did I say about this the last time ? sort of same thing : suddenly super live with even my wondering whether it now was really live (for the recording) which I never believed (still not actually, but you get the gist).

[manisandher]

Once in a while I play Autobahn (that stupid 23 minutes or so track from Kraftwerk)...

Haha... I played this only yesterday. But it's no big coincidence because I have to play this (and 'We Are the Robots' also) at least once a week - my 5 year-old and 2 year-old sons loves these 'songs'. A few months ago I created a fictitious world called 'Planet Zog', and these two tracks are 'Zogan music'.

But what is amazing is that only yesterday I realised how much is in this track too. Nothing explicit that I can recall now, but lots of "Oh, I never heard that before."

FWIW, I usually play these tracks from 'The Mix' album. The 'We Are the Robots' track has some serious LF going on.

Peters BNC cable!!!

Just out of the box, installed and listened to Stanley Clarke.
Ohh, ohh, it’s crazy, unbelievable what this cable is doing,  NOTHING!  Transmitting datas only!!!

More details in the highs (cymbals), better resolution and the speakers disappeared  (in my critical listening room).
Never heard the  upright bass with this “live like” acoustic  on this recording from Brian Bromberg. (http://www.amazon.com/Wood-Brian-Bromberg/dp/B000FQJPBO/ref=sr_1_5?s=music&ie=UTF8&qid=1417174890&sr=1-5&keywords=brian+bromberg)

In other words, the other cable (RG223) is destroying the last 20% of the listening “potential/possibilities”.
I’m excited to hear what this cable is digging out on other details during the “burn in” period.

This cable is a very, very good selection/research from Peter.

Hey Joachim, glad to hear another great report about the Blaxius. Just wondering if you switched to bnc connectors on your amps and NOS1a or was this initial test with adapters? If with adapters then you should get another bump up in SQ with bnc connectors?!?

Hi Brian,

I just switched the cables only!
Never heard such a piano as with the Blaxius!!!

Hi All,

Sinds a week now i have my NOS1 upgraded and the BNC connectors are mounted in my NOS1a and the amps are also provide with BNC.So two Blaxius cables came along with the upgrade.

To be really honest i was a bit scared for what this all would do to SQ and if the money was well spend. Really i had something to discus with my girlfriend. My opinion after a week is that maybe it is a lot money but it is very very well spent. It is that i have so much trust in everything Peter brews. ;-) ;-)

More and better highs. Looks like a life recording. Crystel clear and a Piano and guitar sound so unbelievable real now.
And someting i would have never expect
is that there is loads  more bass out of my Open Baffle speakers. Really for the first time i am completely satisfied with the LOW that is coming out the woofers now. Strange thing i nodiced that it looks like the more bass is coming out off them, the less the woofers are moving. But maybe i am wrong. (EDIT What i forgot to mention is that with the NOS1a there are no errors during playback anymore!! 

Again Peter and Ciska have done it!


Keep up the good work they are mostly appreciated

 
Until next time

Gerard

[PeterSt]

Oh guys, I love it. It really seems to work out regardless of the situation.

If I can say so ... next up is VJ. He, like Joachim, will be trying "with the adapters only" first.
Three more are due next week.
In between a guy named Paul may have his second attempt.

We wish you all a nice weekend !

Hi,
It should arrive sometime today!
Looking forward to it.
