Once people start receiving Mike's amps I suspect you'll hear some good things about them... But how good are they compared to the Maraschino's and MEGAchino's is another question. Tommy has been doing Class D for a long time. And he doesn't source off the shelf chips from anyone.  :thumb:

Nice, Thanks! Guess we'll see when the Icepower amps hit the new owners!  :thumb:

It would be interesting to know how these MEGAschino amps would compare....
We design all the circuits, so Cherry Amps are not built from "inflated-price, one-size-fits-all, pre-fab modules".

Side story: We worked with SANYO years ago on high-performance Class-D.  They were using an ice power circuit in a multi-chip module design that was cancelled.  They told us even our old technology was light years ahead of ice power but the cost of our high-power Class-D was too high for mass market.  We explained that our technology was intended for ultimate audio performance, not cheap mass market consumer audio.

We pride ourselves in a unique high-performance technology built with patented and proprietary circuits that WE DESIGN.  Our technology doesn't require gobs of negative feedback as used in mass market pre-fab modules.  Some say high-feedback amplifier designs are responsible for screechy highs and smeared imaging like the Class-AB amps of the 1980s.  We also don't require complex compensation networks allowing much less output filtering for flat, extended response into difficult loads.  Our extended response also allows better control at high frequencies.  Other Class-D designs are adversely affected by speaker reactance, some so bad that capacitance on the output changes their operating frequency.

We design our hardware FROM SCRATCH (down to the smallest component) to fit the product, and we design the entire product around our own circuits.  Therefore, we don't need to make sonic sacrifices in order to fill as many "sockets" as possible.  This allows us to reach new levels of performance on the bench, but more importantly, into your ears.

The MEGAschino is like (sonic wise) the well-regarded Maraschino with even more extended bandwidth and massive added headroom.  The result is an elegant and luxurious sounding amplifier capable of driving just about any speaker on the planet, even the BIG power-hungry ones like Legacy Whisper, Tekton Double Impact, Magnepan 3.7i, big JTRs (210RT, 212RT, 215RT), etc.

Here are some MEGAschino differentiating features:
  • DC coupling end-to-end ---- response down to 0Hz and NO BASS PHASE SHIFT
  • Low output impedance across the entire audio band ---- other amp manufacturers rate output impedance (or damping factor) only at 100Hz while we measure it at 100Hz, 1kHz, and 10kHz
  • Optimized for SONICS above all else ---- we start with amazing bench specs, like 128+dB SNR and 0.0008% THD+N, then we tweak for sound AFTER that
  • Black background and micro-dynamics ---- 120dB SNR, 0.005% THD+N at low power
  • High power ---- MEGAschino channel boards are capable of comfortably driving 1000W into 4Ω and up to 2000W into 2Ω
  • Extended bandwidth ---- up to 150kHz
  • Patented and proprietary circuitry designed in-house ---- we are one of the few amp manufacturers that still designs circuits as opposed to dropping yet another module into a fancy box!
  • Experience! ---- I'm the guy with 30-years Class-D amplifier design experience

I had a chance to visit Tommy last week and listen to the new MEGAschino monos.  He had them hooked up to JTR Noesis 210RTs, speakers that can readily take advantage of the tremendous power on tap.

The combination produced an effortless and invisible reproduction of everything we listened to. The JTRs offered razor sharp imaging, and the MEGAschinos got out of the way and just delivered to the JTRs whatever was sent to them from the DAC DAC HS and Squeezebox Touch source. Regardless of the volume, from whisper quiet to deafeningly loud (110dB measured at the listening position, and we didn't turn it up all the way), the system maintained a realistic finesse that sets this equipment apart from the competition. The sound pressure this setup can reach is deceptive, because there's absolutely NO strain or distortion. Lows remain tight and well controlled, maintaining tonal balance and good punch at any volume, and highs stay articulate and refined, with zero harshness.

Tommy has another winning product, delivering on his goal of complete transparency and ultimate control of whatever speaker load you decide to feed, with a bottomless pit of power to play at any volume you dare.
Thanks for your kind thoughts.  Glad you enjoyed the MEGAschino MONOs!

No Heat Sinks ?
« Reply #29 on: 17 Jan 2018, 06:15 pm »
We were asked to comment about the lack of heat sinks in the MEGAschino design....

The MEGAschino directs heat through the motherboard into the chassis.  The chassis, or enclosure, it heavy gauge steel, and a massive heat sink.

You don't need heat sinks for powerful sound.  The MEGAschino approaches 1000Wpc into 4 ohms, so there's proof heat sinks aren't necessary.  With reasonably efficient speakers (mid 90s), you can reach SPLs of 110dB or even 120dB without significant distortion ---- from the amplifiers, anyway.  There are not many speakers than can run such high SPL without loads of compression (distortion).  JTR is one quick example.

We appreciate the onslaught of interest in the MEGAschino.  Who would you like to see review this amp?  We're looking for someone with at least a double digit pro review history and very high quality speakers....  Thanks.

We have tried many times, but since we don't advertise there, they have declined.  I guess it's no problem to ask again, but we have reviewers from other publications (not at liberty to disclose) asking US to review the MEGAschino!  Thanks.

MEGAschino reviews ?? Absolutely Anybody but Stereophools or Absolute Idiots as their as biased as the Democratic Party!! They both sugar-coat for their paid audio advertisers and cater to them with glowing reviews when another non-advertising concern is clearly head an shoulders superior!!

A good case in point is Tekton Designs various loudspeaker line, many of which have been reviewed by both rags esteemed reviewers with glowing praise, but which will never make a publication issue because its taboo, they don't pay advertising fees. Why else would well heeled audiophiles be dumping their $20 Grand to $50 Grand speakers for the Tekton Double Impact or Double Impact SE loudspeakers ?? The Double Impact SE in automobile gloss paint and loaded internally, with all upgrades tops out around $ 7000.00 ... you do the math.

The "new MEGAschino" will be in the exact same situation with these pay to play folks! Shameful their reviewers voice will not be heard because of silly biases. The subscribers from both rags deserve better. This amp is going to be stellar in every way with the power of the Classic Cherry design with the Maraschinos clean clear extension!! People this new power amp is going to be something very special ... period!

Regarding both fore mentioned rags ..... both only useful for upper Michigan rustic outhouse duties.

Congratulations on a fantastic new product.
I have just a few questions:
I wonder if you could tell me what would make the most difference, the bigger transformer upgrade or the higher capacitance upgrade?
What is the maximum power consumption?
Are there going to be faceplate options like red or white or silver?
Keep up the good work.
This is very exciting!
Thanks.

It may be obvious to some of you that I am much better at designing amplifiers than marketing.   I was recently asked by a large publication editor (no guesses, please) what amplifiers are in the "MEGAschino genre".   Can you help me out and suggest some models to compare against in the $3,000-20,000/ch range?  By the way, "old stuff" still counts, if it's still being sold by the manufacturer.  We realize many brands haven't put out new amps recently.  I'm also interested in who's actually designing amplifiers and building them with their own technology these days.  I heard Levinson is doing that.  Other big names have fired their designers and turned to modules.  Has anybody gone the other way?  Thanks for any help you can provide.

Well, for low level to medium level listening, neither are necessary.  However, more caps are great for low to medium level listening as well as loud "pulsating" music.  For continually loud music, bigger transformer.  For "knock you off your seat" type playback, both!  Thank you for your kind post.
