I can't help feeling inline attenuators are not going to be ideal.. you might need to suck it and see.

i think the NACs and probably also the N272 have a huge input headroom, so I doubt you will have clipping issues, and these would be very audible... but it might be also a load/impedance thing between the Hugo and the Naim NAC.. and obviously our ears are very sensitive to the effects of this.

Thanks and I'll see what Naim HQ have to say.

Please see below the response from Phil Harris.

"The analogue input on the 272 is good for over 9v RMS before clipping" 

Just to be sure I would like to ask if for Tidal my Lenovo laptop - JRiver - Chord silver USB Cable - DAC-V1 would have benefit from microRendu + good 7V power source?

When I bought my DAC-V1 I understood that Audiophilleo in my DAC and BitPerfect takes care about all what I need in digital side.

I haven't got a DAC V1 but, given that it is already galvanically isolated, I would look at USB reclockers/rebalancers/RFI filters like the Audioquest Jitterbug or ifiAudio iPurifier2 first .. lots cheaper, and easy to return if you buy them online and find no benefit.

A dumb question, my forte, my present system comprises a dedicated Macmini, running Audirvana which Id like to keep, into a Gustard U12 into a nDac etc.  From what Ive read the Microrendu could be a good upgrade, however could I integrate it into my present system, if so how?

@ROBH

if you get a microRendu...  The Gustard connects the mR to the nDAC.  

Now you can set the mR in Dlna mode.  The MAC should be able to directly control the mR over an ethernet connection (I have not done this). 

Another control option would be to run a dlna server on the Mac.  Use Lumin or Linn Kazoo to control the mR on a phone or tablet. If you do it this way you can move the MAC (and all its power supply noise) away from the HiFi.

The microRendu is RJ45 in and USB 2.0 out. I'm not familiar with the Gustard or what it does, but it accepts USB in. If you want to connect directly to the nDAC, you could use a USB-to-whatever converter. That said, I can't get away from the idea that there is overlap between your various components once we include a mRendu. After all, the mRendu is essentially a streamer device. And you have that already with your Mac Mini.

In your system, the mRendu would probably replace the Mac Mini, provided you have a NAS or some other network storage (e.g. USB connected HDD to your router).

The Mac Mini only has 1 RJ45 port. You either connect it to the internet with that or to the mRendu. So, in your first solution you make streaming of e.g. Tidal impossible.

Your second solution effectively turns the Mac into a NAS. But this requires a network of a minimum of Mac Mini --> router --> mRendu. And the last connection must be hardwired. Also, you don't need DLNA. You could also stream from the mRendu using MPD and map a network drive from the mRendu to the Mac Mini. But then Audionirvana really serves no purpose anymore for playback.

Long story short: better to just choose either Mac or mRendu as a streamer rather than try and shoehorn the mRendu into an architecture with duplication.

I am assuming that you have the Mac Mini attached to a network switch.  You would also attach the microRendu to the switch.  If you are willing to control the mR via a app (tablet or phone) you can then move the Mac Mini to another location (and the hard drive) and connect it to your switch to serve up the data as the Tablet calls for it.  

 

If you really still want to sit at your Mac Mini and direct what files are to be played you would then need 2 network connections (1) for the Mac and another for the mR.  In this scenario the output of your Mac Software would send the music to the mR.

I am also assuming that the Gustard is a USB --> S/PDIF interface.

Tell us how you are controlling the Mac Mini now and we can be more specific.

Thanks for advises. Has maybe someone tried different sources connected with the same cable to DAC-V1 and bit perfect. Any differencies found?

We assume that software does not change. I have noticed that different softwares give some different results.

Gustard's function is as an isolator, to remove the inevitable noise from Mac Mini (as any other computer). 

Re using Existing MM with mR, it is no different from a NAS - just needs the MM to have UPnP server software (Many available)', then just like any NAS it will serve avross a network to the mR. The attached Thunderbird disk is no different from an internal drive.

the interesting question is how does mR to DAC compare to Audirvana in ultimate mode on the MM through Gustard to DAC?

I cant answer the last question (how does mR to DAC compare to Audirvana in ultimate mode on the MM through Gustard to DAC?) yet.  Regarding UPnP server software, Plex seems a good option but does not support AIFF music files, all my music is in this format, any recommendations?

I post also here an answer of Steven Hopkins from Naimaudio to my question if I need any additional devices if bit perfect in DAC-V1 USB input is ok from my laptop. The answer was: "If your DAC-V1 passed the bit perfect test then there is no need to worry or put any device on the USB cable." He also kindly attached a technical document telling about asynchronous USB input of DAC-V1. 

Hi Tuomo,

I could be getting hold of the wrong end of the stick, and if so I apologise in advance.

The mR is not the equivalent of, say, a Regen or Audiophilleo. It replaces the laptop, a non-specialist and noisy piece of hardware. I believe the mR DOES contain Regen technology as well, and this bit may well be superfluous in your setup.

I have been running the mR powered by a TP 6V supply for three days. It is in DLNA mode and is fed by J River v22 from  either an HP 8440 i7 Win10 laptop or a Win 7 dual core desktop all on the same network (with CAT 5e cables).  The DAC-V1 (v1.16 f/w) and TEAC UD-501 are both used. Normally the DACs are fed from the PCs directly via USB connections.

1. The mR seems sensitive to noise - I had to replace the standard SMPS on my TP-Link switch by the iFi iPower which fared much better. There probably would be further improvement by replacing the router and the switch power with low noise LPSs. This can get expensive!

2. I expected the mR to better the laptop, and it easily does. Resolution, 'space and air' are much better but remains musical ( it keeps your attention).

3. I expected the mR to better the desktop,  it comes close but does not quite match it (low end def and the perceived 'ease of flow' of the music). It probably would equal or surpass it if I invested in linear power supplies for the router and switch, but this  then gets rather expensive for a computer based system!

 

If you already have LPSs lying around (or care to invest), and normally use a laptop - this will likely be a big upgrade.

Thanks Brilliant,

Your experience is really valuable. It means that there really are some differencies.

I asked from Naim support: "People say in Naim Connection forum that different computers would effect on sound quality of DAC-V1 even signal is BitPerfect and using USB input."

The answer was: "I would simply advise that you audition a couple of different computers in that case and decide for yourself."

Maybe I could try different configurations. I have now a coaxial cable television connection in wall socket having also a max 40 M transmission rate in the same socket/cable - normal Cisco router connected to this - normal Asus ethernet switch - Lenovo T420s laptop - Chord Silver USB-Cable - DAC-V1 (1.16). I have a big desktop at 5 m distance, but I understand that USB cable to DAC-V1 should be max 1 m to avoid signal errors. This becomes interesting if also power supplies of router and switch would have an effect on sound.

Would be nice to hear further experiences of different people...
