nac112/nap150 warm up

mine took about 2 weeks, although i have to say that within the first week, i was already very happy with them.

how are you powering the 112? (just curious).

i have now had this combo for more than a year and know it well. in fact, i am listening to nac112 right now -- and i can tell you it is a serious little pre-amp.

your profile doesnt say what the rest of the system is? what speakers? what source? rack? etc

regardless, i hope you start enjoying your system soon.


enjoy

hi ken,
the rest of my system is the cd5/flatcap2 and monitor audio s6 speakers all coming from an isotek clean line mains filter,i havent got the cd5 into the flatcap yet as im waiting for a cable to connect it,
thanks kev.

Hi

I have a similar set up (minus the FC2) and my amps took at least 2 weeks to warm up. Although the 112 manual does say that it can take up to 5 weeks to bed in

Cheers

Stevie

You say it doesn't sound too clever but could you provide some description of the problem as you perceive it? Are you using NACA5 or another speaker cable? What equipment stand are you using? Also have you tried it without the Isotek and if so was there any difference?

David

I just bought the same combination too (4 or 5 weeks ago or so) and like you the lead for the FC2 to the CD5 was missing to start with. I was quite disappointed in the initial sound - it was all a bit out of focus, and not what I heard in the dealer.
When the lead arrived it made a BIG difference - like pulling everything back into focus. I was really quite surprised at the difference it made. And its got better as time has gone on.
You want to watch your choice of music too - the quality of recording becomes more noticable: some CDs sound much better than others.

What's an Isotek clean mains filter?

Paul Rowlands

oakey, i would definitely remove the mains filter and power directly for some time until you are used the sound of the equipment as naim intend. later on when all is OK you can experiment if you like.

i gather the flatcap2 can power 2 pieces of equipment -- i therefore assume you are powering your 112 and cd5 from it?

remove the mains filter and then...

Martin I maybe stating the obvious but just to make sure. The lead did'nt really make the difference what did was using the Flatcap 2 power supply to send volts to your CD5.
The NAIM approach of using external power supplies to improve performance is very successfull.
Enjoy your kit secure in the knowledge that you can when you want to (later on after you have come to love the sound) upgrade the sound with more sophisticated power supplies from NAIM. IMHO the Hi Caps work wonders on both the 112 and the CD5 and are a step further up the ladder than a Flatcap 2, though always "demo" any upgrade before you buy to satisfy yourself.

What you have now is a great system as it is. Enjoy

Yes - I didn't spell it out, I imagining it would be obvious from the context. But I guess it is worth making clear. Thanks for the good wishes.

By the way, Oakey - what is the problem with the sound? - What are the shortfalls? I was wondering whether you are noticing the same as I did?

I know superstore mains filters are frowned upon - but my setup hummed terribly until I put one of these on. I wouldn't bother if there had been no hum - but it may be the lesser of two evils.

Hi Martin

Apologies for stating the obvious earlier. Just making sure since you are new here. I realise that does NOT mean you are new to hifi etc.

On the mains filter and your comment about hum. That sounds odd. I have never had any hum from the NAIM kit. If you disconnect the 112 from everything except the other NAIM bits (just with the CD5/flatcap/150 connected) does it still hum?
If it does are you earthing anywhere except through the mains plugs? If not check with your dealer.
If you only get hum when you connect other non naim equipment like a digi box or VCR or DVD or TV etc you probably have an earthloop.

Of course that does'nt get rid of it. A lot of digi boxes etc cause hum

Hi
Re the hum - it should say it's the kit itself humming, and it's not coming through the speakers. The dealer said it was from the transformers, (presumably in the FC2?) caused by 'dirty' mains power. He seemed to think it hasn't unusual. When I put a filtered supply on, it stopped. The only other thing I have connected is a RigaP3 through a stageline
I think I might experiment over the weekend to see try and isolate the cause.

Martin

How good are you at staying up really late?

If you can hang on until everybody has gone to bed around you the mains should be in as low a state of use as it gets. Might be worth seeing if the hum is better.
You must have really rough mains.

I'll try it, and switch off the AV stuff on the same ring. (I usually stay up late since its the only time I get to listen to what I want to listen to!). BTW - there's a whole thread I just found on this topic .. "Transformer Humm on New Naim gear" ... it seems that the problem is not at all unique!
