Sakso136,

I've been very curious about Aries Cerat for several years as I'm very intrigued by their design approach and philosophy. I thought the Genus amp used the 813 DHT as output tube driven by the Siemens  so called "super tube". Regardless I imagine this amp paired with the Nenuphar sounds outstanding.  I have no doubt.


In a perfect world I'd love to hear your amp compared to David's superb Found Music 2A3 mono blocks. Two very different amplifiers for certain but the Nenuphar bringing out the best of both of them.

Hi charles1 dad,
Correct aries cerat is using 813 tube,but recently made a new 845 version using the elrog 845.
The  813 model gonna be discontinued in the future.
The power passes from 25 to 22 watt i think,but sonic improvements are there according to stavros the conceptor.

Hi sakso136,

 Thanks for the update information regarding the Genus amplifier. The 845 is a wonderful tube in my opinion. I've heard the Elrog 845 in a friend's amplifier and it was heavenly. A few years ago I had the Elrog 300b in my amplifier and it was beautiful sounding but unreliable (I had the very early production tubes). I understand that the latest generation Elrogs have solved the reliability issues. Given the Aries Cerat approach your amplifier will have a fabulous over built power supply.

Indeed.
The 2 friends i was referring to,are a close friends,and i m familiar with their systems,tastes( specially the lm 845 one).
All our audiophile group where thrilled when hearing the combo nenuphar+genus.
Honestly,no idea how much is the damping factor and negative feedback on the genus,but,when in action,you feel that those 22 watt act like 300 w.
The transients,the dynamics,the bass,seperation, i can go on,... all there with ease.
Those 22 w are specials,and many people said,it has no problem driving even mid efficiency speakers.
Another friend,owning sb amati,ordered genus at the same time as me,afterhearing it,let see how it goes....
The lm845 friend went and bought elrog845 and elrog300b,replacing his psvane acme 845 and 300b,and he concluded that elrog is the winner.

@sakso136   Sami, thanks for the wonderfully helpful and informative posts. I learned through your findings from the amps (and tubes) driving your Nenuphars. 

I'd love to get an 845 amp in for listen as well.

Let us know your in-depth findings once your AC 845 Genus is in system. What a pairing!!!
