PS Audio LanRover

Hi Andrew,

 

I read with interest your review of the PS Audio LanRover in Gramophone and would welcome your further thoughts.

 

I currently "cast" my PC-based music via Plex Media Server, using Chroecast Audio (ethernet conneted) into the Naim nDAC. (I too use a range of Naim productes like your good self!). Hi-fi is in another room to the PC.

 

I am interested to understand whether the LanRover is likely to improve sonic performance. Whilst I appreciate Chromecast Audio (for the price) is a great entry into casting/streaming, I realise it will have some sonic disadvantages compared to more costly solutions. The use of the LanRover into my set-up would appear to be straightforward - if I'm understanding it correctly!

 

In addition, I use CA to stream music from Qobuz. Pardon my ignorance, but not sure how LanRover would/would not improve the sonic performance of this streamed music.

 

Grateful for any further advice

 

Many thanks

Paul Gibson

 

 

 

 

 

 

usb is perfect as it is

Of the three digital audio interfaces (usb, coaxial and optical) usb is the best, and of the two others, coaxial is often marginally better than optical. Whether any of these differences are audible is a moot point, however (almost certainly not). What is also clear is that usb is already very good, and does not need any costly gadgets. Even very long low quality usb cables produce bit perfect datastreams at the receiving end.

As for the Chromecast Audio, I think you are unduly worried about its audio quality. The analogue output is very good, even if not as good as some stand alone DAC's. Again, whether you would hear the difference is not clear. I use one in this way with a set of revealing Quad 2805 speakers, and the audio quality is impeccable. Using the digital optical output with a good external DAC certainly allows for a better measured response (apart from some inaudible jitter), but it is not obvious that you would hear the difference. In your case, feeding the digital signal into your Naim DAC, you are all set for perfection. The LanRover is a device that works on usb, so will not work on the optical output of the CCA. Save your money for something useful.

Thanks Willem. Yes, take your

Thanks Willem. Yes, take your point. Further reading on the topic since posting does appear to question the real value of such add-ons. I do use the optional optical cable with my current set-up and like you I have been pretty impressed with the sound quality of the Chromecast Audio. Only marginal differences to equivalent 16 bit CD or USB stick fed into nDac direct.

Be interesting to hear any other users comments, but as you say, perhpas better to save the money for another use!

Thanks.
