I never use the internet from this machine, but obviously it is connected to the router, and thus only protected by the firewall. Depends on what we call "obviously". I mean, I don't. But it may depend on what you want. My situation : Tablet -> WiFi -> Router -> LAN Cable -> Music Server (means : contains the music data). Now careful : Music Server -> LAN Cable -> Audio PC. The above is the physical connection. Now the functional one : Tablet(RDC) <-> Music Server (RDC) <-> Audio PC. So Tablet controls the Audio PC via the Music Server. No Audio PC is connected to the Internet here. Only to the Music Server. The Music Server *is* connected to the Internet, but only because that is convenient for me. So if I detach the (in my case) ADSL cable from it, no internet but still all the required connections for audio. Peter ![scratching](http://www.phasure.com/Smileys/default/scratching.gif) So this "music server" needs 2 LAN ports and therefore can't be my old lappie? Am I correct? Regards, Stanley

Ultimate Audio Playback / Chatter and forum related stuff / Re: YFS USB cable tour

OK, my turn to say a few words about the YFS USB cable.
First a big thanks to VJ for organising this tour.
I collected the cable at Coen's personally, and so we were able to chat a little. From Coen’s description above and our chat I got an expectation or prejudice that this cable would not be my cup of tea, because I generally don’t like systems that have razor sharp images and very prominent “individual instruments”, because that is not how I hear life music in acoustic spaces. It often is kind of clinical and lacks naturalness, tone and intergration. But I was wrong.
Remember, I have a different set up compared to Coen. The NOS1 is not yet “a” (but will be soon). My speakers are full range magnetostatics (not electrostatics!), so essentially I’m listening to aluminium foils with an 1 ohm impedance and therefore I'm convicted to large powerful amps. I listened to various album, like Andy Narell (Slow Motion), Miles Davis (In a Silent Way), Tomasz Stanko (Lontano), Kraftwerk (the Mix), Gentle Giant (the Power and the Glory), Beethoven (String Quartets), Willy Deville (Miracle), Tool (10000 Days).
I agree with Coen that the YFS is detailed and reveals more information compared to the stock cable. The stereo image is wide and deep and it all sounds fresh and natural. I do understand Coen’s remark that “the super sharp focus to cause the soundstage to be incoherent like 'each instrument/sound on its own'”, but in my setup and in my perception this is a pro. Some rock albums from the seventies I only play in the car, because they tend to sound “overflowed” and messy, when the music becomes full, especially at high volumes. The YFS now gives “space” to the music it needs and suddenly those albums sound better in my living room. I even could listen to “ELP’s Pictures at an Exhibition, which I have not be listening to since the introduction of CD. Furthermore I think that the low end performance is also better, maybe not a room resonating, sloppy bass, but a tight and well defined bass that I think is more real and involving. All in all, I like this cable and it gives me a real and natural sound.
I’m very curious how it will sound on the NOS1a. If that can be arranged I will report on that.
To be continued . . Stanley

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. Stanley

Yet another question concerning XLR. My monoblock amplifiers are of a symmetrical (balanced) design. The input consists of both XLR and RCA terminals and the RCA's can be changed by a BNC quite simple. The only thing that worries me is that using the RCA (BNA) will involve an extra network in the amplifier that might be detrimental for SQ. ![scratching](http://www.phasure.com/Smileys/default/scratching.gif) I suppose I should just try it and see if the negative effect of this network will be compensated for by the Blaxius solution or are there other aspects / effects to consider? Thanks Stanley

Oh, and if you're using any mains products (filters, transformers, regenerators, etc), you should try by-passing them to see what they're really doing to the sound. I'm now convinced that all you need is the lowest impedance power source possible, and most of these devices simply do not allow this.
Good that your SQ changed for the better ![Happy](http://www.phasure.com/Smileys/default/rolleyes.gif) These mains products can be puzzling. I had bad results with PS Audio Powerplant Premier. Currently my computer and NOS1 (not yet a) are on a Purepower 1050 and my poweramps are on a seperate dedicated ring (6mm2 mains cable). Recently I bypassed the Purepower and the SQ detoriated significantly. I'm curious if the NOS1 a will be less sensitive for the Purepower. To be clear for the readers, the Purepower is not a transformer or filter, but regenerates a clean 230V power. Stanley

Ultimate Audio Playback / XXHighEnd Support / Problems with resizing coverart
|
on: November 01, 2014, 12:43:50 pm

I added a bunch of new albums to my music disk. When resizing the main coverart (Folder.jpg) some files are resized (to 500x500 at 500KB), but with some other files I get an error message "Acces to the path D:\Muziek\Rock\....etc. is denied" when trying to overwrite the files to 500x500. What goes wrong here? ![scratching](http://www.phasure.com/Smileys/default/scratching.gif) Regards, Stanley
