XLR interconnects

fernar ·
At the moment my N272 is driving my power amp using RCA interconnects...  However my power amp also accepts XLR interconnects - so I was wondering if there would be any benefit in replacing the RCA interconnects and connecting the N272 to the power amp using a pair of 4-pin DIN to XLR cables? (I believe the cables I will need are the same cables that would be needed to connect a NAC252+Supercap to a NAP300). I know that XLR connects tend to used with balanced connections (between...

Hi Loudmouth Volts = Amps x Resistance Power = Volts x Amps Basically what this means is that your amps will have to produce double the power when the impedance of the speakers is half 8 ohms. So hopefully your amp will have a stiff robust power supply that will enable the amp to double output power into each halving of the resistance. So if 50w into 8 ohms it is 100w into 4 ohms it is 200w into 2 ohms If the amp is not up to it with the power supply and or the output trannies cannot deliver...

Hey david, Ok, that was very informative and I think it is helping me understand this a little better. But I didn't get an answer as to whether or not a naim amp (5i, supernait, superuniti, or one of the NAP separates) would affect my speakers, in a negative way. The superuniti is the only one I have seen with a 4 ohm rating.

I've only had 4 ohm speakers for the past 25 years and have used them with all kinds of Naim amplification, including NAP140 chrome bumper, Naim UnitiQute, and now a NAP 250.2. The NaimUniti is 50 WPC at 8 ohms and 90 WPC at 4 ohms, and since it is based on the 5i amp section, you can expect the Nait 5i should work just fine with your 4 ohm speakers. At 88 db sensitivity, they are more efficient than the 85db 4ohm speakers I drove with the lower powered UnitiQute (30/45 WPC).

Re: Another 4 ohm speaker question indie

Richard Dane ·
Loudmouth, all Naim amps are rated into 4 ohms, indeed, the number after the NAP refers to the sum of both channel's power into 4 ohms. Hence a NAP250 is rated at 125 w/channel into a 4 ohm load. So long as your speakers have an unreactive load, i.e. they don't vary wildly in impedence across the frequency bandwidth, then a nominal 4 ohm rating should be fine with any Naim amp. However, if the impedence varies wildly and 4 ohms is the average, with dips down to 1 ohm or less at certain...

Re: Another 4 ohm speaker question indie

Simon-in-Suffolk ·
Hi Loudmouth, further to Richard's point, another consideration if your speakers go to a very low impedance at a particular frequency is that the resistance/impedance of the speaker cable comes more into play. Ie you should keep it as short as you can whilst observing Naim's amps minimum lengths for inductance purposes. Otherwise you might find certain types of transients are sapped away, as the energy has gone into heating your speaker cable rather than moving the air despite your amp...

I suggest you read Richard Dane's response. That explains it all nicely. I was until last week using Linn Kabers, which are 4 ohms, with a NAP180 and it was fine, so long as I did not push it too hard. Remember that more speakers are destroyed by underpowered than overpowered amplifiers.

Many years ago, back in the 80's when I first started working for Doug, I was asked to take home a pair of Linn Isobarik DMS speakers and the original shoebox NAIT ! I thought he was having a laugh, there is no way you would normally partner these together. However, using an LP12/Ittok/K-9 I was amazed at how involving the music was with this extremely unlikely combination. It went loud enough, but demonstrated the surprising current capacity of the Nait's power supply, being capable of...

Loudmouth = my experience with 4 ohm speakers (mid-range Dynaudios - also notorious for needing high rated amps - all the blurb says they are even 4ohm across their range) is: - the 'smaller' NAIM amps will drive the speakers OK - but: a- the amp cases can get warm/very warm - and sometimes even my beloved NAP250 shut down (the protection circuit cut in) - but this was only after prolonged listening at high-ish volume levels. b-bass lines and general control suffer against the bigger amps -...

My 250.2 stays mostly cool and never goes beyond lukewarm to the touch driving my Dynaudio Contour S1.4s (4 ohm, 85 db sensitivity). I play jazz and classical -- almost all acoustic music -- at moderate volumes. But even if I throw on a big symphonic CSO playing Rimsky-Korsakov's Scheherazade and play it loudly, my 250.2 still stays lukewarm. I think it would take a lot more to bring the 250.2 to its knees.

Re: advice needed for novice

I don't feel confident of advising you further than saying nd5xs is not (I don't think) duplicating anything. It includes a dac and looks to me to be a logical next step for you though others may have a different view. I have just got one (nd5) myself (aiming for nds ultimately) and am hoping to get a unitiserve in time - using a qnap nas drive to store ripped CDs.

Congrats! My recommendation would be to get a s/ h naim dac and hook up the unitiserv directly to it via its digital out.

To lance's point, I wouldn't have bought a unitiserv myself - I run a synology nas into a naim steamer via Ethernet cables, but since you have, I think the naim dac is your best option.

Re: advice needed for novice

Hungryhalibut ·
You need to consider whether you want a streaming system, in which case an nd5 would make complete sense. Alternatively, you can plug the Serve into DAC, as MM suggests. Don't listen to those who say that they would not have bought a Serve - it's a pointless observation given that you now have it. I own one, and it works beautifully, with no need to fiddle with computers to rip CDs. Think about whether you want to play CDs, as if you don't, there is no point getting a Uniti. Then think about...

since when is a balance control not found on "high end equipment" ? Some even have a separate volume control for each channel. That would even be worse for OCD! I am somewhat OCD myself but like the volume control, if for nothing else to make sure both channels are working when I switch from one extreme to the other. Also, like having a mono switch, btw. david

There is no guarantee that the resistive tapers on a potentiometer line up EXACTLY where the centered or unity-gain detents would be placed along the travel of the wiper; detented pots might ultimately be more microphonic, as well. The NAC 202 balance pot (hidden from view, and registered using an optical sensor) is a quite clever solution.

I cope with it by putting the position of the balance control to the point where the sound stage sounds right in my room. I don't think it matters where this is if it sounds right. The 252 and 552 are the first amps I've owned since about 1983 with a balance control, so humping speakers around used to the the order of the day. Still is for some room tuning. If it bothered me I would look elsewhere. Lots to chose from. With the advent of digital sources based around DACs and streaming there...

Back in the day I moved from a NAD c350 to a Nait 5i and wondered the same thing: where's the bass? It seems deep bass is part of the NAD sound. But don't get quantity and quality confused here. The bass detail on the NAD was poor - reach had far exceeded grasp. It sounded unnatural too. You need time to acclimatize to the nait presentation - the nait is far more sophisticated and coherent. The thumpy bass is gone and you've won overall. If that deep bass is still something you can't do...

It's funny you should say that. A friend of mine bought a NAD C320 on the basis that it had won product of the year twice in a row, in fact he bought two of them and then bridged them (why o why i'll never know). My NAC92/90.3 utterly trounced it in every shape or form (musically) so the guy ended selling the whole lot and got a Nait 3 instead - it was a real eye opener for the poor soul as power was everything to him. Needless to say he had learned a valid lesson on his real stepping stone...

Hi, Is there any reason why you are not using NACA5 speaker cables? I know it's a cliché but you really need to try it as I think this will iron out those little niggles. They need to be expertly made up using Naim's own loudspeaker plugs (very important) and be at least 3.5 meters long in equal lengths.

The great thing I like about the Nait 5si is that it is not fussy about what type of music you play through it, it just get's on with it, unlike Naim amps of old. It's not relentless either by trying to spoon feed you with what it likes. To find that it is more mature and at ease with what's going on than the old olive kit, this in my opinion negates any slight leanness in the bass... I think it's fair to say that What HIFI? magazine have given it a pretty accurate review. Enjoy. .

With my Nait XS i think treble is also a bit strangled/rounded and sound can't be a touch bold and lacking a bit richness overall. But of course PRAT, bass kick, stability and fun are excellent.

I own both a Nait 5i-2 and a pair of Evo2-30's and would call neither of them bass shy. I can't imagine the bass from the 5Si to be any less than that of its predecessor. Based on your description of bass and "strangled trebble" my guess is a speakerphase problem. Have you checked and rechecked your speakerwiring on both (amp and speaker) sides?
