Nord One Up Ncore NC500 amps, Class D ready for prime time .....

I get it. Very few pieces have stayed 10 years. A pair of Alon Lotus SE speaker, I think, was the only thing. Everything else is in almost constant rotation. I chase the next high and love hearing the system in a slightly different direction.

It just felt like time for a change. Looking at the equipment list under Joe's name he understands. I have had chocolate for 10 years and now I feel like trying some vanilla. Part of the reason also is while I loved the mc's, they were built in the early 90's and eventually, not next year, maybe not in the next 5 years, maybe not until 10 years, but eventually, they will need to get recapped, and in a smaller city it is hard to find a good repair shop.

I am totally new to this class D subject, but I looked up other amps using the same NCore NC500; one of which is the Bel Canto REF600M and this is the tested output. It also uses the same power supply; SMPS1200. So this is continuous power output, no? I don't know why the product specification sheet severely underestimates this, but I assume the Nord would test with similar results.

It should as the main differences would be choice of buffer design, more elaborate casework and distributor/dealer markup. Same with the Atash and the Merrill Teranis. Bottom line is how does it sound and does it have the power reserve you want with the speakers you are using. If you changed speakers almost anything else would be an easier load.
 
They all are the same amp with same power output - RMS or peak. No one is powerful than the other. Sound wise, they differ in the input buffer implementation. While with Bel Canto and others you are stuck with the sound of factory input buffer, with Nords you can roll-in opamps, though there are only two choices at the moment with most folks (including myself) preferring the SI-994.

Btw, there is another new opamp I would like to try but Colin is somewhat unresponsive to queries these days. Must be busy or something...

I'm quite interested in those op-amps, was thinking about just buying a couple to try!

Well I guess this is not RMS. It's the only reason, since also Colin confirm to me that continous power is 100W and 400W are only peaks.
BTW this is not a problem for me.

There is not enough heatsink area to sink 400 watts RMS , so not surprised. My Class-D crowns use slightly larger than normal sinks and a fan for cooling for that kind of RMS rating.

The fans run high when driving hard and low Z load ...

If you get to try it, please report back. A while back when I asked Colin, he said he was still testing it, so you might want to check with him as well for compatibility.
 
Can I have an advice about which Op-Amp choose ?? I mean the choice between Sonic Imagery and Sparkos Lab depends on the pre-amp we will connect to the NORD ???

What do you think of the NORD ONE PRE-A pre amplifier ???

Bye
 
My understanding is that the Nord Preamp is based on the Abrahamsen Preamp that Colin used to distribute in the UK before they decided to go ID only. If you are in an area where you can try it why not for the price.

As to the Op-Amp I found that to depend more on the speaker than the preamp at least with my gear. The SI will probably be the safer bet and if you decide you want to try the Sparkos later they are cheaper to purchase.

I read everything I could find; this thread in its entirety (took quite a while) and all other reviews regarding the amps before deciding which op amp to have in them. You should do the same. Even after that I am not sure which will be best. So therefore I have both sets coming; I will try both and decide. You are right, it comes down to synergy. Like most gear YMMV.

I have both. Depending on the speaker and rest of the system, you might like one vs other. There is no right or wrong thing here - just what you like and works best with the rest of your gear. The SI's has more air and 3D image, while the Sparkos are more meat on the bones and a bit thicker image. However, if I have to choose one now, I would probably start with the SI as a safe bet and then later on might get the Sparkos to see if you like it better.

No, I am from Italy. Then anybody have tried the NORD Pre-amp here ?

Speaker + Opamp sinergy .... or in general amplifier. That's very true !! So anybody have tried NORD + ProAC ???
Are you all from UK here ?? Nobody got the english premium speakers producer ?? ;-)
