Hi ,
I am using the snaxo to drive the kudos 707. Just curious if we can use one amp to drive the high and mid of the left speaker and the other amp to drive the high and mid of the right speaker?
Read the connect guide and it shows each amp to drive both left and right speaker for each frequency
On the back of your SNAXO 362 does it have a reference to 707.
This was mine
The reason for asking is that a standard SNAXO 362 would not work properly with the 707.
This is the connection guide from Kudos.

Hi.
Yes. Mine shows 707
That’s good.
Hopefully the connection chart helped.
DG…
Yes it does.
But I was wondering if I can use one amp to power both the HF and mid for the left speaker? And the other amp to power the right speaker.
Heard some said that vertical biamp will be better. So trying to see if this can be done
It’s set up to be used as per the connection guide, I’m sure that Naim and Kudos know what they’re doing. Don’t want to risk any damage.
DG…
Assuming the cables from SNAXO to the power amps are all essentially the same, I see no reason why you can’t wire it to have one power amp for mid and treble for each channel. Absolutely no damage risk. One advantage of the recommended way is if there are any differences between the two amps botb channels will be similarly affected (e.g different iterations of the same amp, or even different models like 250 and 300). An advantage of a single amp per channel is that it can be placed close to speaker and so short speaker cable…except for if the amps are Naim old classic with the minimum cable requirement (not sure if NC range is free of that?)
You probably could do that, but why would you?
It misses the whole point of the new Snaxo.
One of the key advantages of going active is keeping each amplifier focused on a specific bandwidth.
No, the key advantage of active is direct control of the speaker drivers with no crossover components between amp and driver, and nothing to do with whether vertical or horizontal active driving.
The benefit of each amp operating in stereo but over the same limited frequency range rather than handling bass-mid and treble of one channel is limited comes primarily if the amps are not identical in character. It does not bother one channel of an amp what frequency range the adjacent channel is handling, though if the amps suffer from crosstalk the question is which is worse, bass-mid of one channel affecting bass-mid of the other, likewise treble, or bass-mid affecting treble of the same channel.
Not sure where you got that “connection rule” from, but the reasoning is awry as it is playing music with drivers incorrectly connected that will blow the tweeters, not the act of turning on (unless you have music already playing when you turn the power amps on, which is against good practice), and if you connect anything the wrong way round the result will be the same whether horizontal or vertical. The absolute golden rule with active is to at least double-check every connection between active XO and power amps and between power amps and speaker connections, and to do that any time you reconnect anything. It is good practice to label the amp s at the back - and it can be very helpful to colour code, with a different coloured adhesive label or piece of adhesive tape beside each input and output socket and wrapping each end of each cable with the same, so only if only like colours are connected all is right.
I have been using Naim 3-way active cossovers for many years. I started off with Naim Snaxo 3-6. So that I could use one Naim NAP per frequency band, I switched the wiring to the output sockets for hf and mid-band. This worked well until I had to dismantle the system and store it for a while. I hadn’t marked the output sockets on the Snaxo and made the mistake of connecting the power amps according to the Snaxo markings. Fried a tweeter. When I sold it, I retired it to standard. Guy in Australia bought it and was delighted.
Moved on to a Naim Snaxo 362. It is in use with home-built speakers having SEAS T29CF002 E0040 crescendo tweeters, ATC SM75-150S mid range and Volt B2500 bass drivers. I have four Naim NAP200DR amps, one each for hf and mid and two for lf. Works very well. By coincidence, the standard Snaxo 362 output level settings are perfect for my speakers (I tried adjusting the levels but realised that the were just right using factory settings so put them back to original settings - I took the precaution of marking the pot positions so I could put them back if required. Pointless exercise? Not really. I had reassured myself that the factory settings were the best for my speakers.
So, main lesson is to be aware that hf signals go to tweeters. Don’t feed tweeters with the wrong signal or you will be getting smoke signals.
I would also suggest one stereo power amp per frequency band. Two if you can afford it. If you have any more power amps, start adding them in the order bass, mid the hf.
