HYPEX,PASCAL OR ABLETEC


Knowing about the many apparently very good class D amps on the market right now and even though I'm very satisfied with my current ClassD Audio SDS-440CS amp, I'm seriously considering purchasing one of these amps to try out in my system. My thinking is that, if I do like the amp in my system, I can just use my current amp to replace an older Adcom GFA-545 that currently powers my Magnepan CC3 center channel and my unamplified (passive)sub for ht purposes. I would then always be able to choose which amp I used for my 2 ch music and which amp I used for ht(cc and sub).

Well, I should get to my point:

I'm using an Oppo105 as the master source in my streamlined A/V living room system used 40% for 2-ch music and 60% for ht. For 2-ch listening, I stream my cd collection and hi-res Flac files from a Synology NAS in another room to the Oppo. The Oppo acts as a stand alone dac and sends the analog output via xlr cables to my class D amp (440 w/ch@4ohms) which powers my Magnepan 2.7qr speakers. For ht, I use the Oppo for decoding surround sound from Netflix, Directv and bluray discs. Two class A/B amps power the Oppo's ht audio outputs to my Magnepan CC3 center channel, LFE sub and in-ceiling rear surround channels.
I've narrowed my new amp choices down to the following four listed below. I'm requesting feedback on any or all of these 4 amp options, especially from anyone who has used 1 or more in their system. My budget is $2,000 to $2,500 and my room is 18ft x 13ft with 8ft ceilings. Here are my options:

Option#1 Hypex Ncore nc400 based amp builds from James Romeyn in Utah. A stereo, dual-mono build is $1,500 total and is rated at 400 watts @ 4 ohms. It includes 2 Hypex nc400 power modules both powered by 1 nc12000 smps mounted in a generic case with a black or silver aluminum faceplate with both se and xlr inputs. A pair of mono-blocks built runs a bit under $2,000/pr. total and consists of a nc400 power module mated to a nc600 smps in each 'NCORE' labeled black case with both se and xlr inputs.

Option#2 Pascal amp build from Aluminati Sound in Ohio. This is a stereo build only that will use a new stereo board from Pascal in Denmark, called the SPRO-2, that has a smps incorporated on the board. Power output is rated at 500 watts/ch @ 4 ohms. Forecasted price is about $2,000 but may run a bit higher. Pascal modules are used in the new JRRG Continuum 2 integrated amp that has received very positive sq reviews. Alumnati is owned by 2 former CNC machinists/fabricators. Their main advantage is their case work. One of the Aluminati owners, Matt Kraemer, told me the new stereo Pascal amp is tentatively named the "X-1" and should be available for order by approx. mid July. He said the stereo case will be milled from a single large aluminum block. The finished case will have an anodized finish (think JRRG cases but milled as 1 solid piece instead of multiple anodized face panels attached to a chassis underneath. The aluminum case will have a blue power/status light mounted underneath projecting downward.

Option#3- Abletec amp modules in the DSonic M3-600M mono-blocks. I'm not certain which Abletec modules are used in these amps but the price is $1,950/pr. and power output is 600 watts/ch @ 4 ohms in black cases with a blue power/status light with both se and xlr inputs. The Abletec modules have built-in smps just like the Pascal modules. According to DSonic's owner, Dennis Deacon, the 600Ms and their top-of-the-line 1500Ms have similar sound characteristics, even though the 1500Ms use Pascal modules(likely either a MPro or XPro module).

Option#4- Identical ClassD Audio SDS-440CS amp to replace my older class A/B amp that powers my center ch and sub. This option is least attractive to me since it would mean my music amplification would remain the same and I wouldn't be auditioning any of the newer class D amp modules. If I liked option 1,2 or 3 above better for music playback, I would simply move my existing CDA music amp over to center and sub duties anyways. The only benefit of option #4 is that it's the least expensive at $630.

I've ruled out some amps, like the Wyred4Sound and Red Dragon offerings, because they use the older Ice ucd power modules typically considered sonically inferior to the newer Hypex Ncore, Pascal and Abletec power modules. Any comments comparing the sq of these options is greatly appreciated, especially if you've owned or listened to some of these. I do understand that there is more involved with how various class D amps sound than just the power modules utilized, such as high quality components and custom input stages.

I should also say, just like Audiozen, I have never actually heard a Hypex, Pascal or Abletec powered amp. I'm just curious and base my optimism on the positive reports from owners, listeners and professional reviewers. If I had a larger $10k plus budget, I'd likely just buy a completed amp based on the Hypex Ncore nc1200 power modules, such as Merrill, upcoming Mola-Mola or Acoustic Imagery.

Thank you in advance for your thoughts, comments and suggestions. Please feel free to suggest other reasonably priced class D amps I may have omitted.

Thank you,
Tim



Much like Audiozen, I am basing

You're very welcome Mikela! I'd love to hear your experience once you setup the new multichannel system using Pascal and Anaview amplifier modules.

okay, Ive found a a german? hifi forum someone comparing the art0 module with ams anaview.:
but would now like to describe my aural impressions of the Abletec ALC0300. I did have some bad luck .. and get the modules rather late. Nevertheless, my sincere thanks to Patrick for all the effort and reliable carrying !!!
The already could shake the first few bars from the official housing at reception evening was well understood ... but the anticipation is one of the most beautiful feelings.

Evening like my Reference 3A Studio M3 (92 dB) and the Linn preamp connected and ... it came out ... oh wonder also tones ... phew ... so at least everything right. The following 3 days went by Monos and were complemented by the 2 small ALC 100. A Center for the bridge mode and one for the small rear speakers. As far ... so good. What struck me at the ALC 100 ... low noise. The ALC 300 are totally quiet ... the ALC 100 rushing softly to himself. It does not sit too much ... just barely bearable ... and from 1.5m distance no longer very disturbing.

Previously I had used the kit from Art0.de. Which has built the Tripath 2021b and to max. 14 Watt afford ... what I have, however, never been used. My speakers have an ingenious concept from legendary developer Daniel Dehay. Is dispensed (in most of his Kostruktionen) virtually at a crossover. The result is a very fast, musical, time-accurate speaker with very high Abbildungsfähigleit. In addition, they are satisfied with a few watts. I have operated with single-ended tubes of power class 1-8Watt many years ... I could never have noticed that deficits in dynamics and depth despite the low performance. On div. Parties to 250 man ... I could also make their abnormal level stability proof ... and every time! Music material ... with a handful of watts. To make it short ... ...
To speakers that are designed like mine ... you will definitely with the Abletec ALC 0300 not happy.

Since it depends on the first and not to the 300th watts. When I read the first sound description of Oliver ... where he had written of a "hardship" ... was the day before I had received the package. Hardness?!?! ... But I know my various Ref. 3A too good ... hardness that is there really a problem. Therefore, I had immediately demanded again ... and Oliver had improved somewhat. Shortly before the response I had to build almost no desire, they still aufz ... because of the long anticipation I got it but then made ...

Oliver has understated. What the Abletec have then delivered to my LS was hard ... very hard ... even after 4 days of continuous operation ... as my hi-mate came to visit an ear to finally throw in the amplifier ... was the high frequency range very tiring. The low season averaging does not exist - the amplifier reproduces a depth Stamp level. The room is quite large .. untenrum missing trotzdemein some punch. What bothered me the most .. the cold is the final stage. No melting ... not magic - just cold, lifeless.

What has struck with the only positive ... the higher the volume .. the better it is. If it were not for this over-present treble would be ...
On my speakers lacked a scary part of the fine dynamics. In some shots we have seen in comparison to Art0 that all details are overrun. In my chain they just did not sound - she presented herself as a foreign body. Fine drawing, coarse -and fine dynamics, body, melting and depth without end ... all that was back when I had joined the little droll Art0. This I burdened by low volume on battery only with an input power of 1.2W .. Room increased volume 2W ... from 4W rang the neighbors by Whattsapp by ... whether it was party again ... and why I'd not invited .. . at 8W would surely the police come ...
My conclusion: For Speakers - like mine is the ALC0300 inappropriate. A cross check with ner small Canton showed that this can live with the final stage ... and great aufspielte. The effect described above I could not find there. At the Canton I can not connect the Art0 as this then acts quite stressed at elevated low volume.
So ... all a matter of the chain. A cure is not Abletec.
Although my buddy said ... like the Art0 airs ... I could but reach the end of the search ... but who wants that because even ...
Who after describing another tip for those cold winter days ... has the play instinct is still there. I would like to try the AMS 1000 ... maybe there is a near here ...
It will be exciting ...

Many greetings
Murphy,
Are you looking for a new amp and can't decide between AMS or Ncore? What's your preamp and output impedance? What speakers are you using?
