  1. I It's for sale, right now and right here where I spend my Summer seasons: Cortona, Tuscany, Italy: 8 rooms, 2 bathrooms, fireplace, et cetera (250 sq. m.); and, of course, garden & garage: 580.000 euros/ 682.650 USD. I know, I know: it is not fair... P.S. I don't know the owner
  2. @SUPATRAC as you can easily image many of us here use the Linn Sondek as turntable. Speaking of me, I'm a Sondek/Keel/ EkosSE guy with some spare parts for a potential second Sondek;so, would you mind explain a couple of questions about your arm? 1) Has the Supatrac Blackbird the same geometry of Linn arms? 2) Can the Blackbird be mounted using a Linn cut armboard? 3) Besides the Linn Ekos SE/Supatrac Blackbird £2800 price difference, are you confident about a comparison between them? Just in case the the 1) 2) 3) answers were positive, last but not least one: 4) is it possible the mounting of the Supratac arm on the Keel for Linn arm or are you going to design it? [As you probably know, the Keel for Linn arm has the Linn arm collar integrated to the sub chassis]. Thanks in advance for your reply and congratulations for your design.
  3. @Daveyf You might take a look at this one: Supatrac Blackbird Tonearm. it seems that it has been designed having the Linn Sondek in mind. Same geometry of Linn arms. Found on the Pink Fish Forum (3d 'Ekos killer price?'). There is a video review by 'Hi FI AF' on you tube of a Sondek/Supatrac Blackbird/Troika combination. It' s a new kind of unipivot arm: SUPA comes from Sideways Uni-Pivot Arm: the pivot works horizontally. In the video there is a nice explanation.
  4. TooM...les, (less is better) I can second your dealer here: the first hours with the retipped Akiva were terrible and obviously I did just the same they did. You must just spin records for a while. That was my experience and I hope it will be the same for you. P.S. Are you sure digital stuff is Covid free? I wouldn’t take this kind of risk these days. Stay safe with your LP 12 .
  5. Rille, AKIVA / EKOS SE the Akiva was introduced years before the Ekos SE landed (2006). As the design remained the same, the sonic improvement of Ekos SE over the black Ekos depends above all on mechanical ones (titanium tube, better bearing housing and so on), therefore any Linn cartridge sounded better on the new arm. Again, as the design remained the same, there wasn't a substantial change in the tonal balance of the arm even if in my opinion the Ekos SE eliminates or at least reduces very much that slightly ringing sounding which goes along with the Ittok and the the black Ekos and produces a more musical midband. So, I wouldn't disagree if someone said that the tonal balance of the Ekos SE is less bright than the former arms. EKOS SE / EKOS SE/1 If I remember well the Kandid landed in 2013. I don't remember when the longer shell Ekos SE was introduced but there's no mystery about the reason: the Linn HQ was asked for a more suitable arm because mounting some non Linn cartridges - and even the Linn Adkit - on the short shell of the Ekos was and is very complicated. The Ekos SE/1 has a longer shell - 2 millimeter, if I recall right, and a corresponding shorter tube. Another difference is a better setting of the anti skating spring but this one had been already introduced in the later Ekos SE. I guess this subject has been covered somewhere in this new Linn Forum. Anyway, my point is: it seems there is no sonic difference between the two arms, at least between the later Ekos SE and the new SE/1. My Linn dealer has a full analog Klimax Sondek plus the Tangerine Stiletto plinth, yet with the shorter shell Ekos SE: "I use a Linn cart. - I quote - why should I change the arm?. I prefer a shorter shell and a longer titanium tube." AKIVA / KANDID In the last 5, 6 years the Ekos/SE Akiva has been my arm/cart. combination. 2 carts, 3 iterations, the last one being a refurbished one with the same Ogura boron cantilever & stylus which right now is around 120 hour old and is my best sounding Akiva without any doubt. That's quite logical: both my Akivas have been bought as second hand by Linn Dealers and lasted around 400 and 300 hours respectively, so they gave me not their best, so to speak. My point is: if you have an exhausted Akiva, you can get that sound back with both Ekos SE iterations. Likewise, I'm quite sure you'll get the same Kandid sonic signature with the old or the new Ekos SE. EMT / URIKA The mass of the Ekos SE is around 12g, the compliance of the Kandid/Akiva is very similar to the Lyra carts: you may check the Lyra web site which is very informative. You're right to worry about the output voltage of the EMT cart. The Urika gain is 62 db, you didn't mention which kind of line level preamp you have ( how much gain): if you have a traditional volume gain like mine, having the knob indicating h. 9 or less, could affect the sound quality.
  6. Jochen, on the 'concerto audio amsterdam' web site right now there is a picture with a Sondek/Ekos SE/Lyra Atlas Lambda ( https://www.concerto-audio.nl ) : they can surely tell you something about the sonic difference between the Linn Kandid and the top of the line of Lyra cartridges. Maybe they have tried also the Ekos SE/Lyra Etna combination. Another source about Linn & Lyra combination is Peter at Cymbiosis: he sells all the Lyra line and you may email him.
  7. As I have another cartridge in addition to two Akivas, I wrote months ago to the Linn helpline about the mass of my Ekos SE (short shell). The answer was: "The effective mass of the Ekos SE tonearm would be approx. 12g. Best regards Richard Customer Support Linn Products Limited" I don't think there can be a significant difference between the two Ekos SE versions.
  8. A 3000 hours life for cartridges like Linn Akiva/Kandid, even if with a serious record & stylus cleaning commitmen, seems to me very optimistic. I spoke about that either with Linn dealers with a long experience and with Roberto Torlai and all of them tend to state that a very good performing cart. lifespan after around 1000 hours is rare. Obviously, the sonic deterioration of a cart. is a very slow process and the 'point of no more acceptability' isn't the same for different listeners with different playback system.I guess I am quite demanding about that: two years ago the SQ of my system didn't please me anymore. I pointed at the cart as responsible and invited my record vendor for a second opinion: for him the sound was OK. After a week that Akiva - actually the one is digging right now the grooves of my records after the retipping - was in a drawer and my chain pleased me again.
  9. I have a pretty high spec LP 12 with a Cirkus bearing and a Tranquility magnetic levitation system. Are they any thoughts as to whether a Karosel would be a significant upgrade? Best, John Hirsch John, go to the Hi Fi Kabin forum, linn Karousel thread: this subject has been very well covered.
  10. I'm glad for your decision @TooManyCatweazles. In the last two months I've read many posts in Italian fora about the "retyping route" and found out that "giving a new life" to our beloved and precious cartridges is a common practice in the Italian audiophile world. The last tendency here is the so-called " Waltz of the cartridges": tuning in a slightly different manner your system just replacing the cartridge. Of course, you need arms with the standard Sme collar system and many already mounted and calibrated shell/cartridges combinations. I'm wondering if the appearance of other repair-man in Italy in addition to the well established Torlai is a consequence of this audiophile trend. It is rumored that the new rising star is http://www.cartridgelab.it. Happy New Year! We need a real different 2021 for all of us.
  11. Well, my rebuild by Torlai Akiva has reached and passed around 60 h. now and I can simply say: the original Akiva sound is back. In other word, I can't notice significant differences from the sound I've been accustomed in the last six, seven years. So, in addition to Tendaberry's positive feedback I will add mine. As previously reported, I went for the more expensive option in the Torlai portfolio: mounting just the same Ogura boron cantilever & line contact 3um 70um stylus the original Akiva - and the Linn Kandid & the Lyra Kleos - has been designed with. I must thank an English audiophile for convincing me to go for the retipping route: it's a way to maintain an high SQ and transform your mc cart. investiment in something more durable. ie
  12. HBerg, Yes, a SUT (step up transformer) can be a good choice. I used a HEAD TX-4 (designed by Tim de Paravichini back 1979). It was a fantastic SUT and I kick myself for selling it more than 20 years ago. And far too cheap, nowadays they go for 10 times the price. I used the SUT together with the SP-6B in the low gain setting, i.e. -10dB in the line section. It that way I could use a CD-player as well without the fear of blowing out the woofers if I should switch from vinyl to CD without lowering the gain. In your situation I would look at a cartridge like Hana SH with 2mV output. I think that should be a great match. Just hasten to say I've never heard a Hana cartridge myself but read very good reviews of them. Just a thought. The Hana SH likes to see a load of 47K by the way. Hi HBerg, 1) as said, I'd like to try a step up & SP8 (phono + line) to compare with my Linto & SP8 ( only line) combo. Yesterday I called for a suitable step up and found several good ones with the right transformation value for the Linn (Lyra) Akiva ( 1:24; 1:26 ) at the Euro 700,00 - 1100,00 range. That's a Karousel upgrade territory and then comes the question: Am I so convinced to spend that money for a possible but not sure better SQ instead a certain one? In the last 8 years my system has remained unchanged with the exception of the not long lasting cartridges and the front end: from a LP 12 Cirkus (new) /Walhalla/ Ittok II/ Arkiv to a Lp12 Cirkus /Keel / Ak. Radikal/1 / Ekos SE / Akiva. Five moves, one step at the time and always very happy about the outcome; 2) why should I go for a high level output MC cart? These have too many coil layers which may compromise the superiority of the MC design even over a very good MM cart. I have three real MC carts and very content of the SQ of my chain which also depends on the presence of low level output MC cartridges! I don't agree with many aspects of the Linn HI FI policy but its defense and support of the real MC carts over the decades must be acknowledged. Edited 21 hours ago by HBerg
  13. Very interesting: 1) the h12 o'clock volume position is optimal according the AR SP 8 manual: " Best sound quality and signal to noise ...in the 11 o'clock to 2 o'clock range of the volume control." As already said, I didn't think it was possible such a performance with a 0,35 mv MC cart; 2) unfortunately no switch in the SP8, "there is provision internally to reduce the gain by 6 db" (ivi): not so convenient. Mine is in a low setting mode at the moment; 3) the Benz LP, like most other Benz carts, "loves" high impedance imputes. In fact, you're using the 47K ohms even in the SP11 where you could choose otherwise. So, no need to solder a different resistance inside the SP6! The Linn Akiva is a classical Japanese moving coil cart and tend to follows the rule: best mc loading = 10 times the internal coil impedance. So, to follow your tip I should bring the SP8 to a technician asking for three services: selecting from 3 to 6 tubes, soldering a very low resistance in the phono imputs and reactivating the full line gain. Risky. Anyway, I appreciate the idea of using the phono section of my SP8: in fact, I'm looking for the right step up transformer for the Akiva and make a comparison.
  14. Have you compared the sound using the phono stage in the SP-8? The phono stage in the SP-8 is very good and I would be surprised if the Linto sounds better. With an SP-8 I would rather choose a cartridge with enough output for the gain in the SP-8 to handle. I use a Benz LP in the phonostage in my SP-11 and load it with 47k. The output of the Benz is 0.35mV. I have an SP-6B as well and can also use the Benz LP directly in the phono stage in that preamp. But you need good low noise tubes in the phono section. Hi HBerg, I'm aware about the quality of the phono stage of the SP 8: I had been using it for almost a decade along with an all tube pre-preamplifier Counterpoint SA 2! I can understand your point in using a high gain preamp like the AR SP 11 ( 46 db phono + 29 db line = 75 db ) with a Benz LP , I'm sure is a lovely match. Frankly I'm quite surprised to read that you can "step up" a middle-low mc cart like Benz LP (0, 35 mv) with a 60 db gain like the Audio Research SP 6 or SP 8 (same gain specifications: phono 34db + 26db): I didn't think to be possible in my experience, so I din't try. In the early 90's we did some experiments at my home. The front end was my LP12/Rega RB300/Linn Asaka (0,2 mv). Preamps were: Audio Research SP10 (72 db, two chassis with separated power supply); Conrad Johson PV5 (70db) and my AR SP 8 V ( 60 db) & Counterpoint SA 2 ( mc pre, 30 db gain) combo. The Conrad Johson as alone was unable to "step up" the Asaka producing a SQ like the competitors while couldn't work with the the pre-pre (100 db gain, really too much) ; the AR SP 10 sounded wonderfully and outperformed my AR SP8/SA 2 combo. So, the lesson was pretty clear: mind not only the gain but the quality of the power supply of the preamp system. Surely in your system the BenzLP/AR SP 6 combo sounds right, I'd like to listen to it but I won't take the risk to flight to North, knock your door and, even though masked, felt not welcomed.
  15. The Linto is a good phono stage. Obviously, the Uphorik is more versatile, bur it also sounds a bit different. awhether this is reflecting the Ivor -> Gilad transition, or just technological progress, I don't know. But it appears to me, that the overall carasteristics of the 'Linn signature' sound has shifted a bit over the years, from the warmer side towards a more neutral and clear rendering. While the Linto is typical for the old Linn sound, the Uphorik is representing the modern Linn sound. So it may be a matter of to your personal preferences, which one you like better. My main reasoning to move from Linto to Uphorik was based on concerns about recurring costs of pickups, and a decreasing income when I retire. The Linn Adikt got a lot of credits by quite a few people in this forum, and it appeared like a good fallback option to me. Meanwhile, I changed my point of view and traded the Uphorik for a Urika2 as a part of my summer upgrade package, though. Thanks for your feedback, TooManyCatweazles, I have the feeling that, while there is a general agreement about the superiority of the analog Urika over the Linto, the one of the Uphorik over the Linto is somehow controversial. Obviously, only a comparison "side by side" could give me a clear verdict. With three mc carts at home I don't need a mm/mc phono stage, so at the moment the Linto stays.
