Ultimate Audio Playback / XXHighEnd PC / Re: CPU Fan

Peter, Are the CPU fans still needed? I disconnected one a long time ago. Still have one attached. Hi Gerard, I have only one fan in the Audio Pc and thatīs the one in the CPU. The fan I use is working at 600rpm and is almost totally silent (6db) so if the problem is noise with this fan the problem is solved because it is absolutely inaudible at more than 20cm from the pc, in fact I canīt hear anything even with my ear almost touching the pc case. On the other hand if the problem is the electrical "noise" (interferences) generated by the fan itself, then the problem still exists. I can work in the bios when I need it without any problem. This is the fan I use: http://noctua.at/en/nf-s12a-ulnJuan

Hi Mani, as you see in my previous post the Music Server PC I'm thinking about is quite cheap. I don't use either a NAS nor a tablet as I said. As far as I know and based on what I read here it's not necessary a powerful Pc to be used as Music Server Pc. In fact right now I'm using an old AMD pc with 4Gb Ram DDR2, it works perfectly with the RDC and the two hdd of 2Tb each that I have now in a dock connected via USB3 to this Music Server Pc. It is only that I want to make it totally silent. About to isolate totally the Audio Pc, at this moment I can't build a separate AC mains line but, although I'm using the same AC line for all the system, I can use some AC filters I have to isolate the NOS1a and the active Genelec as much as possible. I'm using also the Intona. To have the Music Server Pc near me it is, at this moment, more convenient and cheaper than have it in another room. Thanks anyway for sharing your setup.
Juan

Hi Fred, I don't think it matters what you do in the Music Server Pc. I mean that no matter the structure of the Music Server Pc, if you have the hdd inside or not, because in the end the Music Server Pc is used to send the music files through the Remote Desktop, to the Audio Pc. I personally don't use a tablet as I have near me the Music Server Pc, so I use a monitor and a keyboard. The problem may come from the noise generated by the Music Server Pc and the switching devices you plug in same power ring than the Audio Pc, like certain components as a Dock for external hdd. The solution I'm working on now is to make the Music Server Pc completely silent and to avoid the switching plugs. To do it I'm going to use an auto refrigerated motherboard like this one: http://www.asrock.com/mb/intel/q1900-itx/I will also replace the HDD containing the OS for a 120Gb SSD with W10 and XXHighEnd (in case I want to use Tidal) and another 500Gb SSD with a selection (Flac ) of the music that interests me more. These SSDs are SATA connected internally. I'll keep the other hdds I have with several Tb of music as backup and to record more SSD. As PSU for the Music Server Pc you can use a fanless Seasonic or a Mini-Box picoPSU. As a PC case I'll probably use something like a Thermaltake Cube V1 but won't use its fan. The cost of this Music Server Pc including the SSDs: 300/400 depending if you already have some of the components. For the purposes of SQ what matters is how to manage the information once it arrives to the Audio Pc (Ram-disk etc.) and thereafter ( NOS 1 etc.). Best regards, Juan

It seems to be a slight improvement in SQ with less edgy sound in general. Hi Juan, in your previous setup did you have a lot of other devices connected to the switch at the same time? I suspect this is where most of the improvement (decrease in noise) would come from. Mani. Hi Mani, I was using the switch with the only intention of making the transference of data faster and more stable between the Music Pc and the Audio Pc. I haven't had any device connected to the switch, it was just in the middle of two Ethernet cables. My music is in a dock connected with a USB 3.0 cable to the Music Pc. That I didn't had other devices connected to the switch is probably the reason I could not hear a greater improvement in SQ. Regards, Juan

My current thinking is veering towards the network switch as being the culprit. I mean, there are all those 'high-speed' digital connections that the switch has to contend with. The noise must be high. Of course, ethernet connections are galvanically isolated by design, but this has nothing to do with stopping noise getting through (something I think a lot of people don't understand). The 'digital die-hards' will tell you that noise in a digital system doesn't matter - that's the whole beauty of digital. But they don't know how digital music works - if the noise finds its way through to the DAC, it will produce jitter, which will kill the sound.
Mani.
Coincidentally today I removed the switch that was between the Music and Audio Pc. It seems to be a slight improvement in SQ with less edgy sound in general. It appears also that the transfer rate is similar to the one with the switch. So now the switch is out and the connection between the two computers is made through a direct cable. Peter was right and it seems that the speed does not increase with the switch, at least it isn't perceptible with only one Ethernet cable of 3m length. Regards Juan

Hey Juan,
A switch is not going to make it faster (as far as I know). So notice that Mani doesn't use anything in between (direct connection).
Regards, Peter
Hi Peter, yes I know that Mani has a direct connection and that's why I propose the use of a switch. In my experience and also with the information I have a switch can make the connection faster. Of course I can be wrong. Regards Juan

Ultimate Audio Playback / XXHighEnd Support / Reset to initial Startup

Hi Peter, in the Save as button when we make right click appears a window that says Reset to initial Startup? Does it mean the original settings that comes in the Ram-disk? I mean, the very first ones?
Regards, Juan
