Hello Everyone,

Are you tired of cookie cutter chip amp designs with terrible reliability that get updated every few months? ''Improving'' from 0.00000012 THD to 0.00000008 THD as if that is audible at all?

Do you want something that actually sounds good and is praised by people who actually know about good sound?

I have a Dynalo Mk2 amp (230V) for sale. This one is ''fully loaded'' and everything is overkill for performance.
  • Class A ( but barely gets warm after an hour of use with my Utopia)
  • Quad Alps RK27 Blue Velvet Potentiometer
  • NOS monolithic Toshiba jfets
  • Fully balanced
  • super symmetry input stage ( it means it can take a single ended signal (RCA) and converts it to balanced without any extra circuitry.
  • Golden Reference linear power supply
  • 3 x Super chunky isolation feet.
It's essentially like a Headamp GSX Mk2/Mjolnir Audio Pure Bipolar without the fancy casework and markup.

I paid 1000 Euros to get it built by @RudeWolf and I received it in March 2021 and I've been using it multiple times a week since then.

Rudi used to work for Sonarworks and he has also built a Kevin Gilmore CFA3 which has received rave reviews. His thread is below:

It has served me very well driving my Utopia 22 and Audeze LCD-5 with zero issues.
It sounds weightier, fuller and more impactful than the built in amp of my RME ADI-2 DAC and any THX-888 implementation I have heard

Power output is approx 5W @ 60 Ohms. With my RME ADI-2 at 0 Dbfs a demo Susvara was loud enough at 11 O'clock on the volume pot. Will drive any normal headphone to ear splitting levels.

Only Reason for sale: I'm raising money to buy an ECP Audio DSHA-3FN as the Utopia 22 is my primary headphone at the moment and this amp is supposed to be incredible with Focals.

FREE Shipping from Spain to EU. An EU sale would be easy but I will consider shipping outside for extra.

Please see my feedback. People are very happy to have done business with me.

Thanks

Thomas

This isn't exactly the same amp that Bob Katz wrote about.
Please read the ad , it uses the same circuit, i never said it was exactly the same….

It's essentially like a Headamp GSX Mk2/Mjolnir Audio Pure Bipolar without the fancy casework and markup.

“Bob Katz review of the Dynalo Mk2 linked below”.

Putting that link in there is tantamount to saying that it’s the same amp. Sure you did.

If you knew more about Birgir’s amp, you would know.

Yes, Bob is reviewing a version of the dynalo mk2 amp built by Mjolnir Audio. My amp is a version of the dynalo mk2 built by someone else.

We can agree to disagree.

But it’s not the same design. The amp does not have single ended inputs for one.

You can ask the moderator to delete my comments if you want, but I’m just saying it’s not proper to state, or try to infer that it’s the same amp in the review as it is not.

The supersymmetry input stage has differential inputs. You get SE by using one half of the amp referenced to audio ground. In this case, just plug in the RCA and short the minus input to gnd to reduce noise.

Stick to the subject at hand. It’s not the same amp as Bob’s review. Period.

It’s not the same amp as Bobs review however both the Mjolnir Pure Bipolar and my amp use the Dynalo MK2 class A circuit from Kevin Gilmore.

Is this sufficient to get you to leave my ad alone?
