Default Goldmund Mimesis 3 Clone, World's Best Amplifier!!!!

Hello DIYAudio members! Everyone who has been following me on these two threads, The Very Best Amplifier I Have Ever Heard!!!! , and PCB order for Goldmun clone , I will from now on will only post here. To everyone else, please enjoy the ride.

I've been in the audio industry for 10+ years and have heard everything from Levinson, Bryston, Pass, Ayre, Rotel, Boulder, Cary, and 90% of all other audiophile manufacturers. I've never heard anything to even belong on the same league as the Goldmund Mimesis 3 amplifier. The design is state of the art, the sound is world class. Everything else doesn't matter.

The goal of this project is simple: To clone the Goldmund Mimesis 3 amplifier 100%. I will not take any suggestions, or upgrades on the circuit. Not negotiable. Only on the PCB layout and construction of the amplifier.

Here's where this project stands and where it will be heading in the next week:

1.) Please see the original, 100%, accurate schematic of the Goldmund Mimesis 3 and the protection circuit below.

2.) The PCB layout is nearly completed and I will be posting it early next week. The basic layout remains as Alex has created, with the now correct parts to reflect the Mimesis 3 amplifier, correct part sizes, correct lead diameter holes, etc. I will be posting the complete part list early next week as well.

3.) I will order a pair of the PCB boards from a high quality US manufacturer. The order will be placed the following Monday after Thanksgiving Day.

4.) I will build this amplifier step by step on this thread, with pictures and explanations. The PCB boards will be tested for quality, functionality, fit of parts, etc. The final amplifier will be tested on a Tektronix.

5.) Goldmund Mimesis 3 has the following power rating specs: 100 watts (2-8 ohms) and 200 watts at 3 ohms. The rest can be found here: GOLDMUND MIMESIS 3 STEREO POWER AMPLIFIER - SPECIFICATIONS

6.) NOTE: All electrolytic capacitors in the schematic have the + shown as an empty rectangle and a - as either a black filled rectangle, or a line.

This is an amazing project that rarely comes about. I hope everyone enjoys it

Nagys how did we go from the Mimesis 9.2 monoblocks being the best you ever heard to the Mimesis 3?

Is it because you wan't to build something more practical power wise?

Agisthos - I've never said that the Goldmund Mimesis 9.2 amplifier was the best I've heard. In that thread I basically said that Goldmund in general was the best amplifier I've ever heard and Mimesis 9.2 schematic just happened to be on hand at the time so I posted it.

But out of all the Goldmund amplifiers, Mimesis 3 is by far the best sounding amplifier. And it also happens to be more practical and easier to build. So this will be my project, if you would like to follow it.

Hi Nagys
It is good to see you back.
I look forward to seeing you build this.

Will you make them dual mono?

Thank you Melon Head. Absolutely! Goldmund Mimesis 3 amplifier is dual mono.

Here's a picture of the real Goldmund Mimesis 3 amplifier. Not only is the sound world class, it also has the best styling and looks of any audio component out there.

Hi Naggys, from memory this is the same circuit as the mimesis 9.2?

Glad to hear that this didn't die! I was starting to lose hope that this would never get going.

Nagys, what are the main difference between 9.2 and 3? I am assuming that 3 is even older than 9.2. Why does it sound better? In 9.2, did Goldmund cut corners?

Nagys' I thank you for going with the build first, now hopefully all the other folk will be pleased and there will no longer be any gridlock and attacks to this thread.

its got lower voltage rails, some folk here say that this makes amps sound better. Intersting though that I recall reading that the high voltage in the 9.2 might have been for sonic reasons as the output voltage was way high for the power output. On second looks, this has lower front end rails than the output. This amp was made uptill 93 I think. The 9.2 was made from 92 till 2002, thats an eternity in this business.

Luke - The schematics for Mimesis 3 and Mimesis 9.2 are 95% identical. Mimesis 9.2 features a few more bypass/filter capacitors, one extra pair of MOSFETS, higher rail voltages, and a few other extremely minor differences.

Here is an updated Goldmund Mimesis 3 power supply schematic, showing more detail:

And an updated Goldmund Mimesis 3 protection circuit schematic (NOTE: The series inductor on the output is 18AWG):
