Hi Melo , these are the information I found .... Shading plate made of beryllium The shading plate, an extremely thin light-tight plate, corresponds to the coil (MC) or magnet (MM) in conventional systems. Due to the newly developed separate light systems for right and left, the shape of the shading plate could be changed and significantly reduced in size. Together with the change from Alumium to Berryllium, the weight was reduced by an incredible 50%. This is less than 1/10 of the weight of a normal coil of a MC pickup! Pickup A diamond with line contact cut on an aluminum needle carrier is responsible for the direct pickup. The recommended tracking force is 2.1 g and the system weight is 7.7 g. Another improvement concerns the internal wiring of the DS-003, a factor 1.6 reinforced internal wiring provides a lower impedance and thus an improved current flow. Equalizer- Amplifier unit The elaborate housing with the well-formed and milled from solid front panel gives the device an elegant look and noble feel. Internally, a new reinforced circuit board with double cross-section traces is used. This reduces impedance, improves current flow and minimizes interference. For the output signal, both unbalanced RCA and fully balanced XLR outputs are available. Moving mass One of the main advantages of DS-Audio optical cartridges is their extremely low moving mass. This is significantly lower than that of conventional MC cartridges. This increases the sampling capability and fine resolution and thus the naturalness and clarity of the playback. Lenz's rule Lenz's rule states that the magnetic field of a coil set up by the induced current acts against the current flow. This is called electro-motive force (EMF) and in this particular case "counter-EMF". This highly undesirable but unavoidable effect affects both MM and MC cartridges, but not DS-Audio's optical cartridges . RIAA equalization While with all classic pickups the generated output voltage increases proportionally to the speed of the needle movement, a voltage independent of the frequency is applied to the DS-Audio optical systems. This means that a very simple passive RIAA equalization is sufficient, which manipulates the output signal as little as possible. Amplification A conventional phono preamplifier must amplify the very low output signal of, for example, an MC cartridge by a factor of up to 1000; here the amplifier unit for the DS-Audio optical systems is content with a factor of 10. This is a not insignificant reason for the extremely low distortion values of the DS-Audio cartridges. Well the classic Cartridge technologie´s development steps into a new dimension . Quiet interesting imo.

@MeloManiac They had developed optical cartridges also The Japanese manufacturer DS Audio offers with the DS-E1 the cheapest entry into the world of its internationally highly acclaimed photo-optical cartridge systems. Considering that a high-quality, optimally adapted phono preamplifier is included, the price charged is tantamount to a small sensation. Conversion with light The DS-E1, which weighs 8.1 grams, uses the same technology as its "big brothers", i.e. an LED light source, highly sensitive photosensor technology combined with a tension wire construction and a sturdy, torsion-free aluminum housing. The record is scanned using an aluminum needle carrier and an elliptical-cut diamond. The manufacturer specifies 1.6 - 1.8 g as the optimum support weight for the system. Supply unit The phono equalizer, called EQ unit, amplifies the delivered signal from the cartridge and also provides the necessary supply voltage. At the output RCA jacks of the phono preamplifier is with over 500 mV sufficient voltage for direct operation at a high level input of preamplifiers or integrated amplifiers. By the way, the DS Audio E1 operates in analog mode throughout.

Have seen that already at the High End Exhibition in Munich in may this year

Unfortunately, I have to note that today's quality of the pressings no longer has the level of the former quality. How often I have unpacked a current sealed LP, put on and heard after a few minutes the first crackle and scratch. Since even a record washing machine is of no use. It's damn annoying because vinyl has also become very expensive. On average, I pay almost 30 € for a current record.Of course, every now and then you catch a flawless new release.

summer evening sky , made this shot yesterday from my balcony

A gallon would cost $7.33 in Germany, what are you complaining about?

Who has the choice , is spoiled for choice . I would also like to post more here , almost 1000 CD's I own. My SACD player is unfortunately hardly in operation although he sounds ingenious. But I'm still addicted to vinyl fever because my TT sounds just as ingenious. Good to have both media

Good Morning Melo , if the channel seperation isn´t correct you need to re-align the Azymuth balance from the whole cartrige at the position where it is fixed in your tangend arm, it must be very well balanced . Another option is that the needle slot doesn´t fit perfect into the cartridge. Or you may check the cable connections from the pick up . Have a look at these three possible option.

another digital trend are these wooden made smartphone hornspeakers , simple , pretty , effective This is a Transmission Line Smartphone Hornspeaker This is a "TracTrix" Smartphone Hornspeaker and this is a" K-Horn" Smartphone Hornspeaker

I also have excotic speaker cables with a conductor resistance of 0.00144 ohms per running meter . Their task is to conduct electricity, to transport the information from the amplifier to my speakers without any kind of discoloration, because I want to hear my equipment and not cable sound. It does not exist, cables don´t have component status. Even if you use silver cables, they do have higher conductivity than copper cables, by increasing the cross section of a copper cable you can achieve the same conductivity as a silver cable.

@dirtmudd and @Full Range The long-awaited 32-disc boxed set of Robert Fripp in the studio and in concert 1977 - 1983 will be released on 27th May 2022. The set will feature many previously unreleased tracks, outtakes and rarities as well as a number of tracks appearing on CD for the first time. The largest in the series, Exposures is the ninth boxset release collecting King Crimson / Robert Fripp material from 1969 to 2008............ https://www.dgmlive.com/news/robert-fripp-exposures-32-discs-boxed-set-robert-fripp-studio-live-1977-1983

still waiting for my Stanton 681 EEE , what an shipping audysee. From Bukarest to Berlin, than returned to Bukarest , shipped again to Berlin, was forgotten to be shipped further to my hometown, has now lain there for 1 week, today I was told that I will finally receive it this week .

I have never seen such vehicles in my life. When were they built ? Could you drive it only straight,the curve radius seems to have been quite limited by the added fenders.

Hello Garry , welcome back . Nice those Sheffield Records. It´s a famous label known for it´s first class audiophile quality standards . For all that never heard anything about this label ...please read further ...... https://sheffieldlab.com/

Very nice André , still listening ....it was recorded at the famouse Van Gelder Studio at 445 Sylvan Avenue, Englewood Cliffs, New Jersey, United States.Rudy Van Gelder (1924–2016) moved to the new location for his recording studio in July 1959. It has been used to record many albums released by jazz labels such as Blue Note, Prestige, Impulse!, Verve and CTI

gonna try ..

another incurable vinylholicer

Nice cover André , my doughter is a anime artist , she´s great in these kind of paintings . As far as I remember I spent a couple of thousands € for her drawing pen equipment, some of them were available in Japan only ...

will be difficult from this perspective

Didn´t I told you that I have a discoball collection every evening I´m sitting there and listen to

Had a break, swum a little in the pool, was refreshing , still 95F here in the late afternoon 5:50 pm . Spinning right now The Doors Star Collection Vol. 2 / 1974 / Midi Label by WEA Records / Printed in Germany
