Since NC-400 modules are DIY, and Maraschinos are a commercial product, this is kind of apples to oranges: the Ncores will sound different in different builds.
I have a NC-400 SMPS 600 amplifier which I love the sound of, but it did take a little work to get it to where it is now.
Amp Designer: if you would like to lend some Cherries I would be happy to do a comparison and post my thoughts here, I used to do listen testing as part of my job at PS Audio, so I am familiar with how to do it and be relatively objective.
System details: DIY BIIIse DAC, direct to NC-400 stereo amp build, to Focus Audio Signature FS-888 loudspeakers.
Send a PM if you are up for a detailed comparison. I am always interested in hearing new stuff.
Last year, I had the pleasure of listening to Maraschino Cherry prototypes (48V version) versus Merrill VERITAS Monoblocks (based on nc1200). It was pretty unfair since the Merrill Audio amps are $12,000 a pair and power output is rated at about 4x the 48V Maraschinos. However, the Maraschinos really "showed up" for this comparison. I thought they sounded quite similar, actually. Keep in mind that the KING 60V Maraschino sounds that much better, and ups the power to about double. An nc400 would be more a matched comparison as far as available power output.
We would like to have a professional reviewer do similar comparisons with our KING 60V version. So far, only the 48V version of the Maraschino has been professionally reviewed. We take customer feedback with just as much weight, however, and they have been very positive about the Maraschino driven with either voltage.
How about taking the plunge and picking up a MINT Maraschino? It's very low cost as far as high-end equipment goes. We understand not everyone can afford a Corvette, just like not everyone can afford a Cherry Amp, but if you have the means, we high recommend them (:
Thanks for your kind post.
