Trying to draw and understand. So I need a cable in this nature
Then one 500DR for left/right bass
And one 500DR for left/right mid-high
And the way the amplifier will know it is bass or not is all down to the internal frequency separation that it know how to do. I just need to plug cable will do.
You’ll get more out of vertical biamping by miles. The horizontal biamping method shown in the diagram is really a hangover from the route to active days. But it doesn’t give speakers much more power or control.
That’s the way mine is configured yes. On the speaker front I just removed the passive jumpers that I used between bass/ mids when passive. It would be a reach for me to try to quantify the amount of benefit but having heard S1 power amps several times it provides some of that type of gain.
Just to add that I phoned Derek G the top guy at Kudos and he told me to configure the way I’ve done it.
So to understand correctly:
Horizontal Bi-Amping (is what @Cohen1263 is doing)
Vertical Bi-Amping
Is vertical bi-amping sort of like using a Mono Block amplifier?
Well it is still a stereo amplifier but both channels are the same (either both left or both right).
But the power supply has a lot more headroom because it isn’t driving two bass loads. Plus the grounds between left and right are no longer common.
A word of caution though. The 500 is a bridgesd amp. So there isn’t a neutral ground like a regular amp. While there are people doing vertical biamping with 200s, 250s, and 300s, I’ve not heard of any doing it with a 500. I’d absolutely sanity check the compatibility of a 500 with Naim before doing it.
Worth noting vertical biamping is just normal biamping for most brands. Many power amps have a biamping switch on the back to link one signal to both channels. Horizontal biamping seems to be mostly a British thing. Again, I suspect because it was a stepping stone to active.
When you talk about 500DR being a bridged amp is making sense that other series like 200 or 300 might be different. So a real caution to take here.
I have to be careful. Tks for all the nice education.
So, no right bass? 
There’s one nap 500 at absolute sound 
but no more goodwill cos they not AD anymore.
Reason for bridging/ bi amping ?
How would one configure vertical biamping using DIN cables? RCA is simple using Y -splitters but I’m not clear how to do it using DIN as they carry a stereo signal.
For example, DAC V1 into 2 x Nap 100 (one for the left speaker, one for the right). Would it require special cables to be made up?
Have fixed it, MrFixit hehe
Just some random thought having see my Scala speaker hole not all covered up 
Very easily. You just get either one DIN to four XLR or user to outputs on the power supply and do two mono DINs to two XLR pairs. It’s dead simple. Naim can make them up or you can order them from Chord or ATLAS.
I am looking at linn klimax solo 500 (2025) , or the soulutuon 501 . Yet to know whether the 500 is mono or stereo .
Gosh.. both are newly released amp. Very exciting. Can’t find any info on the new Solo 500 so far.
Yup been googling , no info still , hopefully it’s mono 
It’s class A/B btw
I agree lol.
AFAIK any Nap between 100 and 200 only has DIN rather than XLR inputs - the Nap 100 also has stereo RCA inputs. How would a DIN to XLR work in this context? Would it need to convert back to DIN at the amp end?
So there are such things as mono DIN cables? So with something like a 272 with equipped with two stereo DIN preouts one could buy two mono cables (presumably one left and right channel variant) and then plug them straight into separate left and right two channel amps?
As for a power supply, are they compatible with plugging into a DAC V1 - do they not try and send power up to the V1?
Yes you can easily make a mono DIN cable or ask for them.
In this context there’s zero difference between one and a single ended XLR except the plug.
Same as before, Naim can supply them, as can Chord, ATLAS and many others.
Thank you - I will look into the options on this.
