A new (huge) R2R high end DAC in town


I have owned the Aries Cerat Kassandra Ref II since February 2018. It was a game changer for me, and I wanted to share my experiences with members here. There seems few posts about this brand on AudioGon.

Like many I would guess, I have spent many years fighting with digital sound, from the very first 18bit DACs at crazy prices, through the upsampling and oversampling years of disappointment, frustration, love and hate of digital sound. I have been through quite a lot of DACs, some bought new, others used, I have assembled kits, modified kits, had kits made for me. Still the search went on. The closest I got in all this was the ancient Audio Note DAC 5, which seemed to do a lot of the things I wanted, but frustratingly not everything. As is the nature of this hobby, the things it DIDN'T do became a bigger and bigger issue for me.

I have owned or had at home:

1. Pink Triange DeCapo with battery supply
Remember this one? A classic and quite radical at the time.
2. Various Meridian DACs circa 1995
3. Various Naim DACs circa 2000
4. A Linn CD12 (borrowed for 4 weeks) (2014)
5. MSB Platinum inc Signature Powerbase (2016)
6. CH Precision C1 (2017)
7. Chord DAVE (2017)
8. Lampizator Golden Gate (2017)
9. Naim CD555 (used item - 2017)
10. Audio Note UK DAC 3.1 (2014)
11. Audio Note UK DAC 4.1 (2014)
12. Audio Note kits 4.1 heavily modded (2015)
13. Audio Note UK DAC 5 (2017)

All of these DACs did somethings extremely well, but fell short in other crucial areas. The C1 for example, initially I was super excited about this DAC, and had it for a full day in my system. But after 3 or 4 hours it began to unravel and I found certain types of music didn't sound good on it, particularly strings and female vocals.

Others such as the Naim had great rhythm and drive but lacked sounstage and transparency. The DAVE had soundstage and transparency but lacked weight and realistic timbre. Others sounded too digital in the true sense, a coldness and lack of three dimensionality, boring even. The Audio Note kit 4.1 when modded was actually very good within it's envelope. In fact I have kept that DAC, partly as it is 'my creation' to an extent. But still not there....

Enter the Kassandra.

I bought this DAC based on PMs with owners and reviews. Crazy? possibly. It had the design traits I had come to respect in the Audio Note and Zanden DACs, such as R2R, no oversampling, no filter and tube gain stage. The classic AD1865N-K chip that some believe is the best sounding chip ever made. But this time 16 of them.
Transformers on the I/V stage, transformers at the output, tube gain stage. All the boxes ticked there then.

Fortunately the Kassandra did not disappoint, in fact it is a fabulous DAC and blew my socks off TBH. It strips away any vestiges of digital sound and IMO sounds more like my TT system as regards timbre, realism and body. It does all this WITHOUT sacrificing transparency, dynamics or drive. Really, it is the only DAC I have heard that can pull this off so convincingly. It's sound is best described as full, dynamic and 3 dimensional. It proves finally that digital can sound as good as vinyl, and the claimed dynamic range of Redbook and higher resolution was always there for the taking.

The Kassandra DAC is huge. 60 kilos and 54cm wide by 520cm deep. It is the way Stavros (designer at Aries Cerat) works, no limits on components or physical size, if it needs a huge power supply, it has to have a huge power supply. I have set my DAC on top of my Granite desk next to my music server. It looks very impressive in the flesh. The chassis is made of thick stainless steel, the curved side cheeks are solid steel, the power supply and capacitor banks are huge. The digital board spans the entire width and half the depth of the DAC and also contains the dual Siemens E280F tube output with I/V transformers next to them. It can output 6v or a powerful 10v as SE or balanced.

This DAC for me has been a game changer, and is my end-game DAC (finally) and I have also ordered the Genus SET integrated as a perfect match to the Kassandra in my system. 

If anyone is in Spain and wants to hear the Kassandra or the Genus please PM me. You would be most welcome to hear them in my system.
Thanks for the review!
Anyone own one in the US and care to share information here?
I live in Austin and have listened to an Aries Cerat dac on a few occasions, as the US distributor is here (Believe High Fidelity). 

Unfortunately I have not listened to the dac in my own system (far out of my price range), though hopefully one day Josh will humor me and bring it over to listen to in my system. So I can;t speak extensively on the sound.

I am infinitely intrigued by Aries Cerat though, and their dacs are among the few that I would seriously look into, if I ever had the funds, as I've yet to heard a negative thing about their sound, and the times I've listened in Josh's system, it struck me as being able to extract copious amounts of low level information.

Josh is also an all around awesome guy. 
Good news for those who wish to experience the Aries Cerat Dac. Make the time to attend the Rocky Mountain Show. Visit JW acoustics room where Joshua has featured the Aries Cerat DAC and AMP for a couple of years now. It is on another level sonically and its dimensional girth is a site to behold. 
18,000 euros. Yikes 

I’d imagine it would be around $30,000 Canadian dollars after taxes and duty. 

A dac for oil barons!
Just became an owner of an Aries Cerat Kassandra Ref II DAC...and could not be happier!

The Kassandra could be re-labelled as an "emotion generating" device. It could also be used for "music therapy"! How could this be the result of a DAC? I really don't know how Stavros has done it...but well done to him! His abilities are truly extraordinary! I cannot imagine a more natural/musical DAC to be possible, yet Stavros has decided that there can be - with the Kassandra Signature and LE models!

In fact, I think buying the Kassandra DAC has been the best way I have found so far to spend my hard earned savings. Thank you to Aries Cerat / Stavros Danos for giving us such an extraordinary product.
Has anyone compared this to MSB select II or total dac top end models? I have heard the kassanda at my friend's, its indeed impressive and leaves nothing to be desired. But wonder compared to the rest of R2R top end DACs, who are making their own ladders/ or R2R modules rather than sticking 16 older chips together per channel. By no means I'm demeaning the kassanda, its a marvellous "end game" dac. pure curiosity here for alternatives that could sound as good or even better?
Here you can see a full Aries Cerat system. Out of reach for most of us. I don't remember which dac they use but it could be the Kassandra. I have never heard these live but Jana who made the video has heard a lot of systems and seems impressed.

@astrostar59 hi thanks for sharing your journey!

Am personally looking for a tube dac now....was looking at the lampi big 7 vs the audio note kit 4.1 or 5.1. 

How did your lampi GG compare with the audio note kit 4.1 or the audio note 5 that you owned? :) in your opinion which was superior and how far away are they from the aries cerat? :)

Lampi has a near 50 % failure rate..decent sound, but channels go out etc..one dealer told me that he almost lost friends who had bought the lamps ..be careful..I would consider the Audio Note doc 5 sig, old model then upgrade parts..these are the absolute top of the food chain!

good luck
ps if you do not have the $$ for the 5 get a day 3 sig with the Burr Brown "K" chips and take out the digital filter and upgrade all the necessary caps!  Best bang for the buck!

Same thing iv heard from a few people with Lampi problems which is oftently never posted much on forums.

Its more of an gamble on if the DAC will fail or last long enough to sell off.

I know this old post. But I could not stop but post this to complement this amazing DAC. I bought Kassandra II ref with Incito S preamp from Aries Cerat. I have tried a bunch of DACs (Mola mola, Luxman D-10X, Esoteric K-01XD with master clock, Naim NX2, to mention few). But man, Aries Cerat Kassandra is in a different league. Gosh, what a great DAC. Amazing tonality, body, coherence, musicality, soundstage, 3D, crystal clear.... It just makes you feel swimming in music. All my future upgrades will be in Aries Cerat lines. I have found this to be holy grail (for my preference). I am not saying others are bad: they were all good, but for my taste and preference, this is it. In my view, I see audio products as: there is Aries Cerat and there are the rest. Nothing has amazed me as much as Aries Cerat products.I can only imagine how good Kassandra II signature and signature LE sounds like. On same note, if anybody is using Impera II pre-amp or Essentia amp, would like to know their impressions.

@astrostar59 Could you please talk a bit more about the differences between the GG and your Kassandra 2 Ref?

It's been a while, are you still in love with the Kassandra 2 ref?


I know it's an old post. I had Aries Cerat Essentia set up with Kassandra II and Impera II and they are incredible. The Impera II preamp can connect with Essential amplifier via its proprietary AC link which is even better, amazing sound.
