Naim R2R Multibit Network player, keeping up the iconic CD555 legend.

Recommended Posts

Naims new $25kaud? Flagship Reference R2R Multibit ND555 network player still using the PCM1704 dac converters.

Maybe with this, streamed and dowloaded music, can sound as good to me that my Linn CD12 does?

Fantastico!

There's a lot of mileage getting got, from hooking up "older and simpler" converters to "lots of pre-processing".... and essentially asking the converter to "get out of the way" so the processing can have it's way.

 

Naim are using the (almost) same processors as MiniDSP, et al. ... where as others are using their own more bespoke efforts all the way up to things like the HQplayer and XXhighend efforts.   MQA also works on the same kinda of mindset (ie. we know what errors your DAC will make - here's a digital filter for it).

shame about the d to a converter in it, couldn't get rid of my minidsp 2x4HD quick enough.

George ,were you using the 2x4hd full range? I tried the 2x4HD processing the sound to both the mains speakers and subs and didn't like the compromises however I now feed the signal to the main speakers direct from the pre and used a second set of pre outs to feed the 2x4HD and then the subs. This seems to work very well.

I tried it numerous ways, but in the end the cons (mids/highs) out weighed the pro's (bass).

Not for me  went back the Linn CD12 (4 x PCM1704K) to active analog 24db <150hz down, and passive 18db >150hz up, best I've had.

Anything else done in the digital was surgical and sterile, except like I said the bass.

You would have a massive latency problem between subs and mains doing this I'm afraid.

These devices (especially the non-HD model) need to be used very carefully with respect to levels .... They need to be quite high, as there is very little margin before the DAC linearity, and noise floor are exposed.

No.   By default there is no delay.    Whether you get any delay or not, depends on what filters are programmed..... so it's up to the end user.    Typical filters will not have any problematic delay .... let alone, a "massive problem".     OTOH, some filters have huge amounts of inherent delay.

If he's doing the bass/room/xover management with it and not going through it for the main speakers, there is a latency problem, even Allan and Kim from Deqx will tell you the same, as I told you before end of story.

 

Back on topic please, and not get this thread locked as well.

Crossover and eq for bass is done on the 2x4hd ,my Gales run full range. A latency problem may exist however the overall sound compared to just using the Gales is , on balance , improved to my ears. It all sounds coherent and ,yes, tunefull. :)

Completely wrong.    There is no delay by default.    The delay you get depends on the filter you program.... and only a specific type of filter (which most people won't use) have a "big delay issue".

Yes you did... and  you were wrong... and I explained to you that you were wrong at the time.

 

This is not "technicality wrong" ..... This is where you are telling people to expect the exact opposite of what they should expect .... and this is quite basic stuff.

 

Yet, it's "end of story".    Niiice.

You have misunderstood their advice.    They are specifically talking about a type of filter (FIR) which has a large amount of inherent delay.

 

People would not use that filter type when they are doing what you are discussing.    The other filter types available, do not cause problematic delay.

 

As mentioned, the device has no delay by default, and the delay introduced depends on the filters programmed.
