Connections for Nac282 to two power amps

Hi all

I am currently using a Nac282 - HiCap - Nap250.2 into Neat Momentum speakers, I have read that Bob Surgeoner used a pair of Naim amps to power certain Neat speakers and have also read that there are some users of Neat speakers that do the same to great effect.

My question is how would two power amps be connected with my amp set?

I have a spare Nap200 so it would have to be Nap200 on the tweeters and the Nap250.2 on the mid/bass units.

Thanks for any help, I have looked at the manuals but cannot seem to find a definitive solution as to what cabling to use and what between.

You connect from the hicap, sockets 1/2/3.

I looked at a manual earlier that seemed to suggest that certain sockets on a HiCap were for mono amps, I require stereo as I will be using the Nap200 for the tweeters and the Nap250.2 for the mid/bass units, not one amp per channel (left or right)

Robert’s correct. Your 250 is probably connected to socket 3 so use socket 2 for the 200. Sockets 3,2 and 1 all provide L&R channel outputs.

Yes, current connection is socket 3 on a non DR HiCap.

So to confirm socket 1 & 2 are stereo?

The dual mono description on the HiCap (non DR) picture I linked has confuddled me…lol

Yes, that’s correct.

Thanks

So all I need is a 5pin to 5pin snaic and some speaker cable and jobs a good un?

You should have a SNAIC4 already supplied with your 200 so use that to connect it to the Hicap.

I tried Bi-amp way back and got lousy result, single amp went back again.
At least don’t expect miracles.

I didn’t go for exact same speaker cables or length.
A point I believe is very important.

How would that work, are the PAXOs in the NEATs split? With separate inputs for hi & lo?

I would use the biwire terminals.

It’s simply a case of connecting the second amp to Hicap socket 2 using a Snaic 4. Then remove the biwire links on the speakers and run one amp to bass, one to treble. It will work fine. Whether it’s better is for you to decide.

Thanks for confirming.

I am hoping that what I read about Bob Surgeoner (and a few others) using two Nap 250 amps (one per speaker) will be beneficial.

To my simplistic way of thinking the amplifier should see an easier load (in my case driving four speaker units instead of eight) and therefore sound better, but we shall see……

I’d connect the best amplifier to the HF driver, so 200 to the LF

By one per speaker I’m assuming you mean one per drive unit. If you connect one amp to the left speaker and one to the right, you’ll get left and right on both speakers. You must use one amp for the bass and one for the treble.

Results from biamping are mixed and you’ll almost certainly get much better results by swapping the 202/200 for a 282/250, rather than adding a second power amp. One big amp is usually better than two little ones.

I’ve seen this before, why is this?

To my mind surely it’s better to have more power delivery to the mid/bass & bass units - (1x mid/bass & 2x bass units - isobaric)?

I am guessing that the higher quality components (if this is correct) is better used in the more transparent driver I.e. - the tweeter?

Bit confused to be honest.

Hi HH

I do actually have a 282/250, but also have a 202/200 hanging around after an upgrade and so thought that it’s an itch worth scratching using both the 250 & 200 to power the Momentum’s, as (allegedly) Bob at Neat has done.

If it’s successful I would purchase another 250 (as close to the serial number of current amp as possible) or perhaps start looking into a Nap300, which will open another can of worms….

It is indeed what you are saying: the better quality amplifier for better separation, etc. I know this was a statement from Linn at the time of the LK100 and Klout amplifiers but it seems pretty much valid nowadays as well.

Perhaps it is easy to swap the two around a couple of times and see what that does :slight_smile:
