Nait 3 (preamp)/Flatcap 2/NAP 90.3 connection

Posted by: u5227470736789524 on 14 April 2004

Requesting some guidance on connection of the above.

I am pretty sure I will take the preamp signal that is running from the Nait3 to the Flatcap2 and connect that from the Flatcap 2 to the 90.3 when it arrives. Speakers would be connected to the 90.3

That leaves two power/signal din on the back of the Nait3 unoccupied. Does either/or both require a "shorting plug" (or just left "empty" ?) and how would I acquire such (shorting plug/s) ? Also, is there any reason for the Nait 3 being used as a preamp only to be itself plugged to a.c. ? It is, after all, getting its power from the Flatcap 2 and the amp section of the Nait 3 is not being used.

Any guidance, clarification, confirmations or criticisms appreciated. From what I have read, the 90.3 is considered a very good, albeit bottom rung, amp, I can seperate my brain/power equip positions and I get to look at more boxes. Wink

Thanks for your help.

I don't think you will need a power cord to you nait. I'm not sure about this either but the the two unused signal plugs are for connecting to an external cross-over (bi or tri-amping) or i guess also a passive straight to multiple amp set-up.

I am currently running a Nait 3r with a Flat Cap to the pre-amp stage. It is not necessary to plug in the the NAIT for pre-amp stage to work. i would recomend taking your NAIT to a freindly dealer who can disconnect the pre-amp side of the NAIt from its power amp side (a reversible procedure involving cutting a simple silver soldered connection between the two sections. With this done you can compleley by-pass the on board power supply and power amp stage of the NAIT.

I was considering doing exactly what you are wneh I went to visit Infidelelity in Kingston upon Thames who told me that adding a 90.3 was not a worthwhile upgrade and I should save up for a power amp higher up the food chain. It is also possible to take the signal from the flatcap back into the NAIT with the fitting of an additional board to the power amp section. The result would be virtualy indistinguishable from the addition of a 90.3. I was also told that given the quality of the electronics involved in the NAIT 3 and 90.3 compared to the serious NAIM kit, that it was not even worth doing this.

I am running my NAIT with the flat-cap happily at the moment, I am saving for a NAP 180 to link it to and a Hicap for the NAIT and later on a proper pre-amp for the complete system.

I was also considering selling both the NAIT3 and the Flatcap and getting hold of a NAC 72 and NAP 140, anyone with a rellevant/helpful opinion out there?

Thank you for your input.

My objective is not to "upgrade", but rather to "complete" my series 3 system. I have no need for more power in any practical sense, and not enough disposable income or time to anticipate moving up the food chain.

My Nait 3 was "split" by NANA in March '03. I thought this (90.3) would be the best "match" for me, and allow complete seperation of the amp and preamp and whatever possible, though not necessarilly expected, beneifts from the seperation of units. And possibly bi-amping oppotunity if that choice was ever made.

I am still not completely understanding when/if "shorting" plugs are used/needed, and where or how they are acquired.

The only upgrade I can remotely see in my future, if I am that fortunate, would be to contract with James/Tibbs Inc. for a pair of yet-to-be produced Ergo .5 speakers. Right now that is time and moneyI don't have. It is a nice fantasy that allows me to dream while enjoying the heck out of what I currently/soon (90.3) will have.

Again, thanks to you both for your input and good listenin'

The Nait 3 can be split internally (by Naim or a dealer) so that the preamp section can be powered by a Flatcap, leaving the internal Nait 3 power supply to power the Nait 3 amp section. The preamp signal goes to the Flatcap and then is returned to the Nait 3 amp and on to the speakers. This I believe maintains Naim's preferred star-ground scheme.

I will be running the Nait 3 preamp section to-and-from the Flatcap and taking the preamp signal to the soon-to-be-delivered NAP 90.3 and on to the speakers. So the Nait 3 amp section will not be used at all, at that time.

Hope that helps, along with anything provided by Potiriadis.

F.Y.I. in a response from NANA re:connections and the 90.3

"Exactly the same as the amp section of the Nait 3"

re: advantages

"The only advantage over a "split" Nait 3 with FC2 is that you get the preamp section of the Nait3 further away from the electromagnetic field and the vibration of a switched-on transformer."
