monteverdi Posted April 3, 2018 Share Posted April 3, 2018 GUTB opinions are not news. Fake opinions? I heard an early version of the Kaluga and was quite impressed as I was with some Constellation, CH Precision etc. but I never heard them in the same setup and room. Any statement which is better needs to come from comparisons with only one variable but one can have an opinion if one hears various components in various systems. I am happy with my hybrid A/D amp!

Agreed. I have not made direct comparisons, but have heard Constellation and various Ncore amps enough times to know that they are comparable, which is better, IDK, but I know I would be happy with either and the right speaker match. I have heard both amps enough times to know that in the right set up the are not flawed in any way, there are likely small differences. I have not really ever heard Soulution at their best, I guess, because they always seemed a bit too tipped up, and uptight (bleached out, nervous, whatever one might like to call it) to me-but again I suspect in the right system they would be excellent.

I find their web site a bit difficult to navigate, you’d have to look. I seem to remember they have dual mono NCore stereo amps and an ICE 1200 stereo amp based on one stereo amp module that is cheaper than the Hypex. It would be interesting if someone asked them to compare the sound of the two amps.

GUTB Posted April 3, 2018 Share Posted April 3, 2018 I’ve owned or auditioned Drive Core 2, early IcePower, latest gen Pascal, Toshiba’s GaN FET and various consumer-grade implementations (ie Pioneer, Sony, etc). Of these, the GaN FET and the Pascal are the best, the IcePower being the worst and the Drive Core not being far ahead. How many class D implementations do I have to cycle through before I’m allowed to say that they suck? If I listen to an nCore and it ends up sucking as per expectations will I be allowed to say that class D sucks? Link to comment

If I listen to an nCore and it ends up sucking as per expectations will I be allowed to say that class D sucks? I would not consider any of those amps equal to the best class D has to offer. Even if you listen to the best class D amp and do not like it, all you can say is that it "sucks in my system", as the system context will matter, as with any amplifier. And, if you listen to any component without an open mind, rather than your admitted "expectation" that it will "suck", then your impressions will be invalid as far as I am concerned. It took the Mola Mola Kalugas, in the right system, to convince me that class D amplifiers have fully arrived and deserve to be considered in the same company as the best in the world regardless of topology.

I used to work for PS Audio and have some direct experience with the HCA-2. It was OK, but has little in common with the performance of the best class D amplifiers today. Much more noise in the HCA-2 for example.

The measurements at stereophile show a fair amount of noise form the transformer coupling into the amps output. The versions with the SMPS 1200 do not have this noise... In any case, this amp uses the NC-1200 module in stock form, just like Merrill Audio, and if even stock form with the included IC opamp buffer it is very good. But the Kulugas use a custom discrete circuit for the buffers... of the same design as that Mr. Putzeys uses int eh Makua preamp. This circuit is almost certainly better than what the OEM NC-1200 modules use.
