  1. Thank you, two more stations in my favorites list to listen to.
  2. Translated from the newspaper article: "Because of Minister Gatz's new media decree, we are only allowed to broadcast digitally," says Dave Verdonck of Radio FG, formerly a local radio station and now a station that only broadcasts digitally from Antwerp Central Station. I can understand (but not agree) that greedy media moguls want to get as many frequencies as possible and also that a bribable minister becomes an accomplice. I also understand (not agree) that people with power could reduce the range/broadcasting power of small stations by fictitious law, but I don't see the point why the small stations are no longer allowed to broadcast analog. What is the benefit for those who prohibit it?
  3. I grew up with FM and have always loved it. Of course, streaming opens up access to the whole world of all radio stations. And today, my Bluesound Node is my (digital) tuner. But let's go back in time to the 70s and 80s. The latest achievement was analog cable. So I could receive in good quality all German and also Dutch, Belgian and other stations from other countries…not only local FM. In the past, I always attached importance to a good quality of the analog tuner or receiver. I had a Quad FM3 tuner and later an Audiolab 8000T. The sound was indescribably good. In the past, analog radio was a great advantage in terms of sound. The radio stations had much better turntables and tape recorders than I had at home in my youth. And the highlight was live broadcasts, e.g. of classical or rock concerts. But today everything is different and much more unhappy. We still have analog FM, there is discussion to end analog radio.... But...analog is only the broadcasting technology. The big problem is that many if not all stations only broadcast music from bad digital sources in analog. For this reason, the sound quality of a very good FM tuner is very disappointing because the limitation is a bad source. As good as 40 years ago the record players and tape recorders of the radio stations were, so bad is today their converter technology to send digital sources analog. They don't care. For the reasons mentioned, digital radio today sounds better than analog radio by saving the conversion. If analog FM were based on analog sources as it was decades ago, it would even be unbeatably better than digital streaming radio via digital receivers today. At least that's how it is in Germany. It would be a cool niche if some enthusiasts relaunched an FM station with pure analog sources to be enjoyed via a good old analog tuner. Postscript. I see a very similar development with vinyl records. It is gratifying that vinyl is experiencing a nice revival. But it makes no sense when people buy vinyl from productions that were recorded digitally. Because then I have the combination of negative artifacts from the world of digital and from the world of analog. One more addendum. When I go on vacation to Italy by car, I pass through the Black Forest in the direction of Freiburg very close to the French border. There is a station that plays only analog sources. I have no special stereo in the car, only standard. But if I can listen to this station for 15 minutes while driving by, then an indescribable sound fills the car.
  4. I would like to ask the OP's question a little differently. He asks: "What Kind of Music Sounds Best? To this my answer is, very many kinds of music. I ask, on the other hand, at what volume does the LaScala sound best? The answer certainly depends on the year of manufacture and the crossover. Outsiders would say, who has such a horn wants to hear loud. This is really not true from my point of view. For loud listening, I know of nothing better than the Jubilee. Of course, it can also play quietly very well. But I hardly know a better speaker for soft to medium SPL than my old LaScala with AA Xover. Even with simple recordings which sound good everywhere, such as Steely Dan "Two against nature", loud or very loud listening is not a pleasure with the old LaScala. Even a 1996 Lascala that I also had was much better out loud. Quiet to medium loud my 1977 LaScala is a jewel, unmatched. One never has the feeling it could not be loud enough. It is consistently very good within this spectrum. For example, a conventional BBC box can be very good. But their window is much smaller. A little too quiet, you hear only half. A little too loud, it sounds very strained. In contrast, the old LaScala is very even from soft to medium loud. Within this range, every! kind of music is a pleasure.
  5. Soundwise I like the JJ 803 in my C22CE Macintosh pre (even though I have been using NOS Sylvania for a year). But I still have not used the JJ 803 in the phono section. The ECC83S short plate could be a bit more immune against microphonics in the phono section. Maybe it's worth a try and if you don't like the 803 you can always use it for other functions, line or power amp.
  6. 1957 NOS Mullard long plates with square getters as well as Tele smooth plates are very superior tubes. Considering their price, I think the JJ ECC83S GP do a great job as a new production. It is an honor to be a serious competitor against the good old tubes.
  7. I have once again found an article from 2010. I had a hunch that there is a special feature around the very normal JJ ECC83S. It is namely also a frame grid tube, which is not gladly told, because this tube is so cheap. And that might explain why SWL likes it so much. It's not that it's a frame grid tube that makes the big difference sonically, but perhaps that it's really made on the original tools that Tesla bought from Telefunken in 1971, and which were later bought by JJ from Tesla. Here is the link to the very well written article in German language. It is about the section: "Alternatives to the Telefunken ECC803S". If you want a good translation, you can enter the text into this best translation engine instead of Google Translator: http://www.deepl.com http://www.elektronikinfo.de/strom/telefunken_ecc803s.htm#Alternativen_ECC803S The JJ ECC83S, normal and gold pin are my next candidates. In some forums in Germany is discussed that it is some "clever" dealers who have "invented" the JJ E83CC subsequently. And to take their words JJ produces the normal tube with a different imprint. These posts talk about the ECC83S being a frame grid tube anyway. But that you can make double the money with a tube if you give it a different name, and re claimed a feature that is there anyway. I don't know what is true and what is false. But one fact is for sure: There is no E83CC in the product listing at JJ itself. See below. https://www.jj-electronic.com/en/download
  8. I think that the question of what music sounds best through the Lascala is also somewhat related to the choice of amplifier. I can understand that your choice of favorite music sounds very good with single ended tubes. I also listen to my Lascala e.g. besides the kind of music you describe also very much like classical orchestral music, Piano solo, but also light rock sounds so e.g. old Steely Dan recordings. I have a KT88 pushpull amplifier. It may be less holographic than SET but it makes the Lascala sound very physical (also at moderate sound levels). This is also one side of the versatility of the Lascala. There are speakers that do not work at all with certain amplifiers. But a Lascala can sound very good but different with different amplifier concepts.
  9. SWL, thank you very much for your pictures! In principle, you like the standard ECC83S / 12AX7 best but with gold pins. And the long plate version ECC803S described by me as having a full bodied sound you also know and it was the first one you ever had from JJ. One more question, have you been able to compare the gold version of the standard ECC83S that you like best with the same JJ tube type without gold pins? Conversely, I know the normal JJ ECC83S but I've never had a gold version of it. It seems worth a try for me and it is very enriching to exchange with each other in such a friendly way.
  10. Sorry but I have not seen a main output on the pics of this amp in the net, if you mean an output which is controlled by the volume pot.
  11. Others will know better but a tape out is usually not adjustable but has a fixed volume resp. voltage. I do not know the Leben so well but photos show no adjustable pre out. Maybe you can connect the sub to the tape out and adjust it via a remote control? But then you would have to adjust the volume whenever you change the volume on the amp.
  12. SWL, all JJ tubes have red letters with the exception of the golden ones. Could you please read which is the exact type of your favored gold pin JJ? I think that the lifespan of JJ tubes should really be reasonable. I like it that JJ is one honest and genuine brand with different types of tubes and a real origin in Slovakia which has bought most of the older original Tesla tools from Czech Republic other than this bundle of fake brands from New Sensor.
  13. If you are looking for a nice full warm sound and if possible microphonics is not the most decisive criterion, (e.g. in the line area less decisive than in the phono circuit), then I have made really very good experiences with the long plate versions of JJ in my C22CE. They are called something different but they correspond electrically to the 12AX7/ ECC83. Just google JJ ECC803S. There are also available with golden legs and I have also seen somewhere a "grey plate" version which I do not know and whose difference I am not aware of. The JJ ECC803S is NOT! a frame grid tube (which may sound harsh to some?). It is a bit irritating because at Telefunken the frame grid tube had this type designation in the past. For me the JJ ECC803S long plate is one of the warmest full bodied and yet not cloudy JJ AX types. EDIT: I wrote earlier that the relatively new JJ E83CC is a frame grid tube similar to the original Telefunken ECC803S. I think this is true and important for both camps to know, the searchers and the avoiders as well. Sometime I read about the historical background re the different type designations. When I remember correctly, original Tesla had already changed the type designation of the frame grid type in the 1960s for some confusing reason and JJ continued to keep it this way…but I am not 100% sure about this background story.
  14. Exactly that does the newer generation of amps like the Bluesound Powernode. It is just an example I am not a rep of this brand. At the moment you dial in a sub the main speaker gets a low cut which frequency you can chose. If you use a normal receiver plus a sub you have to take into account that the main speaker gets full spectrum of the bass region. As long as you listen to normal SPL nothing should go wrong. As mentioned before in this thread a passive low cut could make things more complicated concerning impulse, phase shift, negative influences to the higher frequencies an so on.
