Nac 62 CB and Nap 100 - possible?

As the NAP 100 has no power provider for a pre-amp, then you will need a Hicap [or Flatcap as a junior possibility] to work any Naim pre-amp.

Yes, you need a power supply for the 62. You could either get a separate Naim PS, or change the 100 for a power amp that can supply a pre, such as a 200 or 155.

Thanks gents. So if I was sticking to CB would I need a hicap AND a nap 90 /140?

and if mixing CB and 'BLACK' would I need a hicap and just my current nap 100?

thanks for confirming. 

Sticking with your 100, which is a nice amp, and your 62 you will need a power supply. This could be a CB Hicap, an Olive Hicap or a Black Hicap. You could also use a Flatcap in Olive or Black or a Supercar in Olive or Black. The Hicap makes the most sense to me...

ATB,

Lewis, if sticking with "CB" and choosing to use a CB shoe-box power amp such as a NAP90/110/140 with your NAC62, then any of these amps can power your pre-amp.  However, a Hicap is a good upgrade, just so long as it is in good health (i.e. fairly recently serviced).

As others have mentioned, the NAP100 does not have a pre-amp supply inside so cannot also power your NAC62.  You would need to use a Hicap here in addition.

Thank you gentlemen. Makes perfect sense now. Like you say I think a hicap is a good plan as then I can also get a stage line for my lp12. An excuse to buy more hifi bits!

If considering a Stageline then you'll need to decide on whether the Hicap will be dedicated to that or to the pre-amp - it can't do both. The answer is two Hicaps...

Or just use the internal phono cards in the 62. I doubt a Stageline would sound any better. 

Thanks a lot gents. 

I managed to pick up a isupply which was intended for use with a stageline, it it seems to power the nac62 also, so going to try and hook everything up shortly and see if I can get it all working. I will keep you informed! 

Ok got everything working. So UnitiQute into the 62 and nap 100 into the 62. Only annoying thing I've just noticed is that the connectors for the phono on the 62 are bnc. I've tried using the UQ to 'control' the sondek, so select analogue on the UQ which means it still plays through the 62, but it only plays from one channel. Anyone know why this could be? Also how easy is it to swap out the BNC connectors for normal phono ones, or get adaptor a or something? Would rather do it properly in the long run and have phono connectors instead but advice would be appreciated. Thanks. 

The i-Supply should not be used to power a pre-amp - it was never designed to do so.  Even though it will probably "work", the earthing is not optimal here and whether its current delivery is adequate, I do not know, but I wouldn't risk it. If budget is an issue then at the very least go for a SNAPS or flatcap, either of which is relatively affordable.

Thanks Richard. So I assume the stage line draws less current than the pre amp? It does work Well I must say, but if it's not correct I will wait for a hicap or snaps like you say. 

Any thoughts re the BNC connectors?

Ok, so I got hold of a CB snaps, half size contraption. If I use this to power the 62 will it also need to connect to the nap 100? It says on the back of the snaps one to pre and one to power but not too sure. Means another snaic too arrrrgh

Yes Lewis, another Snaic is required. The signal passes from the preamp, through the power supply and into the amplifier. Don't stop now, you're almost there!

ATB,

OK thanks Mark. I notice the older CB amps do have the same 'lock' mechanism for the din leads, are the older style snaics / interconnects a different design too? 

Also do you not need a cable from preamp to amp or does that one snake sending signal via the power supply do the job?

Varyat explained how it works in his post above.

Regarding the snaics, the current ones will work with the older style sockets, but won't lock. Avoid the original grey coloured snaics - black ones are better. 

Has the snaps been serviced? They are incredibly old, and if not serviced in the last ten years it won't work very well at all. 

Lewis mate, this quest for a half size system is a full-size faff !

Hope it all works out.

Cheers, Chris

Haha yes it is indeed, but my love for the CB is strong so I will persist!

Hungry, I don't believe so but will look into that. The importance of the snaps is great then if it's responsible for dealing with the signal in full. Is the mechanism the same in the hicap, as in pre amp to hi cap to power amp? 

The principle is the same; it keeps signal ground and system electrical grounds close together for best system performance.

Ok thank you.

Sorry I know it seems like I am making a meal of this haha, BUT, it's a four pin din lead from the the snaps into the (five pin)  'hicap' socket at the back of the 62, or (four pin) 'output' socket as pictured below? Also do I need the blanking plug for the hicap socket if not actually using a hicap to power it, or will it work without that?  Thanks again guys.*sigh*

Does anyone know?

You use a 4 pin to 4 pin Snaic to connect the snaps to the 62. I'm unsure about whether you need a blanking plug for the 5 pin socket - I suspect you do. Why not ask Naim directly. 

You just need a SNAIC4 to connect the NAC62 to the SNAPS and another SNAIC4 to connect the SNAPS to the NAP. You will also need to have the 5 pin link plug fitted on the NAC62.
