As ETON gmbh is sold with an unclear future unfortunately i had to redesign .
It will be a design with top of the line scan speak units incl the elipticor midrange with eliptical voice coil
Scan speak has designed a new woofer model with a papersandwhich membrane and a patented foam .
See how that works , its the next best thing to Eton and it should be stiff enough with good dampening , specs are very promising
Further more it will be 2 designs a XPE 3 and a XPE 3 S ( S version with elipticor midrange , ringradiator) 3 stands for 3 way .
Efficiency for both models is 92,5 db .
Flat freq response aim is 3 db downslope , same as the XPE model but ....
The model XPE 3 midrange now has a foam surround so it will not have the usual rubber surround phase anomalies between 1-2 khz , no 2-3 db suck out , this model will be more neutral , the aim is + - 2 db over the whole range 1/6 octave smoothed , the aim is to make a more refined design but Full range in a small package .
Housing (no wood or MDF off course) but a phenolic resin composite as usual HPL
Both are Fullrange small floorstanders , think Wilson watt puppy / sasha size but equipped with the latest 32 cm woofer which should plunge the depth .
20 hz minus 2 or 3 db .( in room )
Front firing woofers plus a form follows function design with a internal midrange speaker cabinet without any parallel walls as to prevent as much as possible that the internal soundwaves interfere with the membrane movement
Further more its completely my fault that the XPE model has had no real exposure as of yet .
They are hard to transport and i have never invited a reviewer ( for example dutch magazine) over or placed an ad .
The new model will be much easier to transport / ship and will be actually marketed / send for review etc .
The basic XPE model remains as is , it will just be updated with latest driver designs.
I thought about designing a (horn )small 2,5 way speaker but once you have tasted the large woofer sound , there is no going back .
And as you all know im not a subwoofer fan

Elipticor mid range with removable decor ring .
This has the eliptical voice coil,
whether it actually improves the transient response has to be seen / heard

Tweeters with irregular shaped aluminium back chamber .
Ringradiator and regular softdome

Yes its also the scan speak textile 1 inch ringradiator , but off course the latest/ current version of that particular design .
Same as the magico mini and V3 had .
Ringradiators have slightly less moving mass versus the full softdome version 0,3 versus 0,4 grams
But the moving surface area is also less .
Ringradiators have also the extra stability in the middle because they are connected to the alumiunium waveguide .
Ps mine can also be equipped later with the scanspeak Berylium tweeter on request .
But its not my thing .
In my view they draw slight attention to themselves which is annoying in the long run

I Just made a down payment on a CAT JL 5 Amourphous core transformer / Black path edition .
I traded in my CAT JL 2 sign mk 2
Should be arriving in may somewhere .
Besides new speakers from Volkern /HPL , i m also designing equipment isolation stands for this new amp and my pre amp , tapedecks and digital .
Also made from Volkern / HPL with added isolation feet

Thanks.
I have only listened yesterday evening a couple of hours
Today im outside in the sun .
Really good .
I think ken has designed a home run with this package .
Nice switch of lights on start up green during play means you re fine.
Auto bias
No transformer hum to speak of/ silent through the speakers at the tweeters
Only 4 powertubes p / ch so not a real costly replacement.
40 kg so more easy to move
SOUND.
Id say more transparent more refined while still having the
cat dynamics / tube humanness to the sound.
Bass is different .
More balanced less annoying on some CD s.
It puzzles me a bit actually because how can 2 Cat power amps with basically the same Fr specs have a slightly different balance .
The new ref pre for example also sounds slightly leaner through the same speakers
More to come

Very very interesting, particularly your last comments/queries. For me, I have found that I seek basic fundamentals, harmonics, dynamic range, unlimited power, etc...but inevitably, to get it from 'great' to 'magic'...usually takes some fine tuning adjustments to the overall system...where 'magic' is defined almost invariably as a personal choice.
So in the cases of 'slightly leaner' I am sure it is super subtle by any form of technical measurement...but your ear is hearing it, and so it comes down to whether you decide it is 'correct' or 'preferable' or whether as you settle the system, you wish to 'finetune' with placement, room treatment,, etc that you already have to get that bid of fullness back or not.
Will be interesting to hear how it settles in as well if this has only just entered your system in the last day or so. Enjoy!

One more thing the amp is designed according to the golden ratio proportions making it a beautifull compact looking amplifier.
My pre amp is the latest design spec afaik with the black gate caps .
But this is the main culprit as to why the balance is changed .
I have to completely reposition the speakers to make it kinda acceptable .
Further away and front firing tw.
Otherwise there is to much high freq reaching the ear .
Strange but it sounds more agile /leaner.
I think it needs time to try to make it sound more converging.
Also this ml dac needs several hours on the juice otherwise it sounds harsh / crap.
Long live tape

Actually i just found out andromeda audio made a gigantic mistake .
After coming home from work today i discovered i connected the 4 - 8 ohm connectors to the speaker input + - , it was late when i got home saturday
But actually the output furthest away is not the 8 ohm connection like i thought but the - minus .
Its a wonder nothing broke , but that could well explain the balance issue.
I m now running the 8 ohm output as it should be .
@ The chassis markings are kinda small , easy to overlook , never the less a stupid mistake .
Ps after listening for 5 min i think it sounds already a lot better .
Luckily , because i was already wondering CAT let me down

CAT is back .
This was the whole problem .
I have it on the 8 ohm tap and the bass is very good , but id say ever so slightly loose .
I ll keep it like this for a couple of weeks and then change to the 4 ohm tap .
Listening to some house music and it sounds awesome to my ears .
All is want is a trapezium shaped listening room so the reflections bounce over and around you , giving a total sound emersion.
.... Plus a nice SONY 4 K projector for Movies
