A great review by Marja and Henk, although I must confess that I was not on pins and needles the way I was when they reviewed the original SGM 2015
One small correction, the heat sink which is connected to the CPU’s is machined from copper billet. The fins on the other side are machined from aluminum alloy
Congratulations to Emile and you
Do you or Emile have an explanation that Tidal MQA was the best streaming?
Thanks
Matt
Thank you for the answer, That is very interesting what you are reporting. The spectrum analysis you performed was it limited from 0 to 1 Ghz for example, or you went all the way up to 4 - 10 GHz? Again I am asking because around 3 years ago we discovered higher emissions of RF on specific bands when optical transmission was used
Hi Luisma,
The radio frequency emissions from our digital gear have the the following transmission paths
- via the AC cable in and out into the AC power network
- via a network copper cable connection
- via a USB copper connection
- via internal cabling with can be acting as both a receiving antenna and a transmitting antenna
4 years ago, we bought a lot of very sensitive RF detection gear with spectrum analysis and stuck the probes anywhere and every where. What became clear was that that galvanic isolation was limited to low frequencies and optical isolation whilst measurably helpful to reduce the RF emission environment, often came with a sonic negative which we could not measure.
So despite optical isolation, when you shape the RF emission environment, the effects can be heard in a resolving / transparent system
Maybe I missed this but has anyone been able to listen to the Extreme compared to the Aurender W20SE or W20. If so what were the impressions?
Most definitely! Some of the conditioners I've tried are known to be the best out there.
There are multi unit condos on my street and houses only a few feet apart. A lot of people crammed in a very short area sharing the same electric grid. Most of my listening is during the day as well, which is when electric use is at its highest. Add to that all the gizmos in my house and a super revealing system, and the decision was easy.
When comparing to my Sound Application C-7 (entry level compared to their TT-7 model), which I still have and periodically test against the stromtank when getting new equipment, I did notice a slight decrease in dynamics, but that was really the only negative I noticed. The pros far outweighed the cons IN MY SYSTEM. The sound is not only much smoother, but has more details and greater depth with the stromtank vs c-7. Has more of that analog sound from the Stromtank.
Edit: Also, even with the Stromtank (and its slightly less dynamics vs C-7), the difference in dynamics from the Extreme vs the Statement was the very first thing I noticed when I switched to the Extreme for the first time.
Another thing I noticed, my system sounds much better with the DCS Bartok plugged into the Stromtank and the Extreme plugged into the C-7. When both the DCS and Extreme are plugged into the C-7, I get that glare back that has been bothering me since before I got the Stromtank. I now think that glare was actually noise bleeding in between the two pieces of equipment. I am uber sensitive to glare/hardness so YMMV. This makes sense since @romaz mentioned the Sound Application conditioners do nothing for stopping noise between the equipment.
Thanks to Romaz for sharing with us all these valuable experience for tweaking the extreme. I would certainly revisit this wealth of information very often. While I would agree to most if not all of his findings I do notice that I seem to be walking a different route and hopefully can still reach Rome some day. I can share some of my experience here.
About 2 weeks ago I started to test the footers for the extreme and it is a coincidence that I also ended up in using the CS2 footers but unfortunately I could only afford the 0.8. Presumably the 0.8 can stand up to 100lb(so is barely enough for the extreme) and it is good for source while 1.0 and 1.5 can be used for amplifiers and gears more than 100lb. We don't have the 1.0 or 1.5 for audition. Actually we started with the Terminator DAC first and the improvement is jaw dropping. As desribed by Romaz it is the immersiveness that is most striking. The layering and density also improves tremedously as well as the 'holes' in between members of the orchestra are filled up. Then we add a second set to the extreme there is further significant improvement along the same line. Adding a thrid set to the Cello preamp pushes the SQ even higher and I finally purchased 5 sets for my system. I hope to get some 1.5 for trial but I have some doubt can the effect of 1.5(money for one set of 1.5 can buy 3 or 4 sets of 0.8) be stronger than 3 or 4 sets of 0.8? Really tempted to get a set of 1.5 for comparison.

Second tweaks that I have tried is even more interesting is the Sablon cable. I have auditioned both the Sablon King power cord and the Sablon 2020 USB cable but they never meet in my system at the same time. I suspect there might be some synergy if they are present simultaneously in the system. Actually we have auditioned the Sablon King more than a year ago but unfortunately at that time my PS Audio P20 was sent for repair and because of the size and length of the Test sample Sablon King it can only be used with the Chord Blu 2 the result is good but not up to a level that it is a must for use in the system. I believe Mark did some modifications afterwards and it is now said to be a must with the power conditioner. A week ago I tried the unpowered Sablon 2020 USB cable in my system connecting extreme with SoTM tx-USB Ultra. Compared with my Habst Ultra III Cryoed silver USB cable it has a slightly warmer mid range but both the high and low are not as satisfying as my Habst cable. The weakest point about the Sablon 2020 in my system is that it lacks layering and that is why I think if the King Sablon is in my system the result may be different. Product synergy is one of the things that is most difficult to predict and sometimes may explain why YMMV.
Talking about the power cord for extreme our experience favour the Kubala Sosna Realization. This is the power cord that helps to give the layering and definition of details much better than the other power cords we have tried. The bass is really authoritative and with detail. We were testing with Wagner Das Rheingold by Solti. The opening 4 minutes Vorspiel gives a very good test for layering and detail of the bass and the system as a whole. When it is done right one can hear the different brass joining in one by one while backed by the double basses and then the different parts of the strings joins in before the voice comes into play. The drama just becomes live with the KS Realization.
I agree that the P20 is not ideal for power treatment but it is still beneficial to connect the power amp to it as it can still give you an increase in dynamics and ease of power delivery . So I only connect the amplifiers to P20 while the source gears and digital gears are connected to some other power conditioners with filters. I would certainly be interested to try the Sound Application TT-7 if it is available in Hon Kong.
On vibration control I understand that this is one of the areas that the extreme may benefit but it is not easy to do vibration control in a 45kg extreme. While I cannot afford the Taiko Tana active platform so I got hold of this FFYX technologies China designed anti-vibration platform that utilize the traditional air cushion for vibration control. By adding a birch plywood board on this platform before putting the extreme on top did add some liveliness to the sound. So the extreme has been sitting there since its first day. There is a significant improvement in SQ by turning on the air pump supplying the air cushions compared with turning off the pump. More analog as a whole.
The above is just my experience with tweaking the extreme for sharing. YMMV. And I believe there are still lots of room for improvement.

CS 2 settle quicker than version one and for whatever reason ( I cant explain why) the 1.5’s settle the quickest in 3-7 days whereas the 0.8’s and 1.0’s settle in 7-10 daysHow long did it take for the CS footers to break in?
I would
I would strongly encourage you to try a set of 1.5's under your Extreme because if you were hearing good results with the 0.8's, your result will go way up with the 1.5's
Personally I would remove the plywood platform and have your CS footers sitting on your lower shelf
As for vibration control your CS footers provide that
Recall months ago Emile stated that all one needs is
1. A good USB cable
2.A good power cord
3. A good set of footers
Then we add a second set to the extreme there is further significant improvement along the same line. Adding a thrid set to the Cello preamp pushes the SQ even higher and I finally purchased 5 sets for my system. I hope to get some 1.5 for trial but I have some doubt can the effect of 1.5(money for one set of 1.5 can buy 3 or 4 sets of 0.8) be stronger than 3 or 4 sets of 0.8? Really tempted to get a set of 1.5 for comparison.
Please read the instructions ONLY 4 feet are to be placed under a component.
The reality is it is very easy. Three is easiest BUT 4 is very doable. On rare occasions the underside of the component isn’t completely flat such that the 4th footer might not achieve firm application to the underside of the component above. If this happens a set of 3 shims is included with every set purchased. They are 3 thicknessesHi Steve,
just for my understanding:
How do you get four feet work stable under a piece of equipment?
Three feet determine a plane but adding a further one makes in my experience the setting of the device unstable.
Thank you
Matt
