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

    A few weeks ago I bought a pair of Nord One Up NC500 amps with the Sparkos Class A op amp. Needless to say I am impressed. This is not the Class D that I remember.

    These are powerful, have 3D, a big sound stage and are sweet with the vocals. Break in seems to take forever on all Class D. But after a few weeks of continuous play, wow, I am impressed.

    Joe

    Anymore changes since we talked about them the first of last week? Has another 150 hours seen any changes. The Nuprime Class D amp came in this morning. I am going to let it cook for a couple of weeks in the family room before trying it with the KO's. Still o.k. here for the tubes for a while.

    According to the website:

    An onboard 8 pin DIP socket allows different Op Amps to be easily swapped in the future to tailor sound and upgrade their Amplifier as required. The Upgrade delivers the ultimate sound with the ability to tune and further upgrade with a sound Menu of OP Amps via the onboard socket enabling easy changes of Op Amps, its called OP Amp Rolling.

    Definitely smoother and more natural. Liking it so far.

    So curious about the NuPrime.

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

    There are supposed to be in the process of testing two more brands of Op Amps to see if they will make them available. I imagine you can buy any of them from PE, Mouser and other places. I am curious to see how it breaks in. Stephen Stone with TAS sure liked it as well as several owners I talked to.

    Op Amps for the Nord. If you want to try the Bursons, Chris at Parts Connexion carries them. The new ones they are testing are from Sonic Imagery and Audio GD.

    Yes, the truth always gets out. These amps are wonderful. I put them back in tonight from almost a week of being away. Other than running as cool as a cucumber (I need some heat - my room is cold), they are great, absolutely love them.

    Mark,

    I plan to bring them to Bruce's and hear them on the Salon2's. If we like the combo, maybe you'd be willing to try them on yours.

    Very nice looking stuff there Joe and reasonably priced. I'm not surprised you like them, Bruno Putzey is the best Class D designer in the business, the output filtering scheme is brilliant and more importantly, load invariant. Definitely not your grandpas Class D.
    Oodles of power. Should work with a wide variety of speakers. Including mine.
    Throw in a nice tube pre and you're enjoying some fine sounds...

    cheers,

    AJ

    Thank you AJ,

    I've been using a McIntosh C52 lately with great sucess, but I do need to try my GAT. Overall, I am very impressed. Best Class D that I've heard so far.

    Cyril,

    For the first 2 weeks I ran them non-stop with my LS-50 speakers and it sounded great. Now my Strads are hooked up and it sounds even better.

    Thanks! They seem tonally more dense and fuller than other Class D amps. More meat on the bone as they say.

    I checked today and the conversion rate is 1 British Pound (GBP) = 1.3959 USD

    Here is a converter to check the latest or other currencies.

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

    If any of you guys want to try out an NC500 based amp and don't want to order from a "new guy on the block", Merrill has one for $2500 using his own designed buffer board. There are a couple of reviews online. Only draw back for some may be that it is stereo only. I think the Nord looks better and has higher quality connectors but that's just me.

    I think I had to pay UPS a small duty fee of $30 or so and I forget if PayPal took a little extra too. I think I was all in for $2250 maybe. Well worth it.

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

    Somehow found out about Nord not that long ago and it got my interest. Not a ton of info on the web so it's nice to hear from someone who has one and likes it.

    Currently running a Gato which uses Pascal class D tech. Would love to compare it to Ncore someday.

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

    Hi,

    I have to say my Nord amps now are outstanding. Love them. Extended break in on any Class D is a must, and these are no different that way, but these are performing better than I had hoped. They seriously kill some amps at 10X (maybe not quite ten times) the price. The Sparkos op amp is supposed to warm up the sound and add some tone and body. I don't know how it would sound with the stock or other op amps but I am enjoying what I have now and absolutely zero regrets. Just wonderful.

    Another forum member has been talking to me about the Gato and loves the sound but is not 100% happy although the company has been awesome to deal with and is very responsive.

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

    The ability to pick the op-amp is a nice option.

    Looks like Atsah 500 and the Bel Canto e.One REf600M monos are also using the NC500 / SMPS1200 combination. Wonder if other companies will try it too, as it seems like the performance is close to amps using the much more expensive NC1200.

    How is the finish on the Nord? The Atsah and the Bel Canto seem pretty utilitarian design-aesthetic-wise.

    Fit and finish is great. The amps are very light but all Class D are light. Heavy cables could tip the unit a little but the whole package is rock solid. Colin from Nord/IQ speakers does a great job on the amps.

    Well, those that use switch mode power supplies (SMPS) are light. Those that use linear PSs (like toroids) can be heavy.

    Mate

    If you are walking away from the Gato situation you might want to look at Abrahamsen. Integrated and then get the DAC of your choice that you can change with technology changes.

    http://www.iqspeakers.co.uk/#!abraha...mplifier/c1vfy

    You would buy direct from Abrahamsen in your country.

    Another option is the Nuprime IDA-16. It is a 200wpc all in one integrated/DAC like the Job and Devialet. Has voltage switch on the back so you can buy from any dealer that has the best currency exchange rate for you.

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

    Thanks Jack, I'm still between several scenarios... Abrahamsen did cross my mind a few times, but I'm trying something even better - to convince my friend to order Abrahamsen for himself as his first ever amplifier; that way I'll be able to audition it. I'm familiar with Electrocompaniet, which is somewhat popular here and basically the same thing as Abrahamsen. I like it, but didn't exactly blow me away.

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

    Would someone be willing to summarize how the NC500 differs from the NC400 modules? I built an NC400 stereo amp several years ago and had it for about a year. It was very accomplished in some areas (midrange and resolution) and lacking to my ear in others (high frequencies and bass) in my system and in my opinion of course.

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

    While the 500 has a bit more power and current capability compared to the 400, I believe that the most significant difference is that the 500 is better setup to accommodate custom input stage designs which can be substantially better sounding than the stock input stage. Many designers are using discrete class A circuits for the input stage with 500 modules. Also many of the 500 designs (like the Nord) make use of the much higher current 1200 series power supply instead of the standard 500 series version which allows for much better dynamic performance and more headroom. The Nord design is also setup to allow you to easily select or change the input stage op-amps of which there are at least a few discrete drop in options.

    I think the amps take one op amp each and that price is for a pair as an example.

    Hi Paul

    I started breaking them in with my LS50. Now I am using them on my Strads and I have to say that they are wonderful. Surprised the heck out of me.
