Miyajima Infinity - Unboxing of the ultimate mono cartidge. Why I need one. Different mono records. 

Don't hesitate if you have the chans to buy one. It is quite heavy close to 30 gram headshell included which means you need a tonearm that can take itWheight-wise.The sound is truly amazing and I compared to the Kotetu and Zero but the infinity really stand out. As I said in the video I did a transfer of a complete record. Unfortunately it was blocked for public domain but I can send a link to an email adress. Just let me know. In the video You get an Idea about the sound.

@@acghifiaudio-vinyland78rpm53 I'd love to. I'm a college student at the moment, so can only dream of being able to afford one of these, but I'll get one someday.

Interesting! I am a novice when it comes to technical things like this. I just play the records with whatever turntable I have got. I have an old Lenco B-52 for my 78s. The needle is a Shure M-75 B T2. I mainly have US 50’s 78 RPMs (Chess, Excello, Modern etc), only a few 78’s from the 30’s and 40’s. I would love to have a mono pick-up but what cartridge would you recommend for my Lenco? I’m not looking to modify it too much, just to use the best I can for the record player I have got.

@@Glendoras I've seen your uploads and you have an amazing collection of records already uploaded. I'm impressed to say the least! Your 45 rpm uploads has a very good sound, some of your 78 also. In some you struggle with variouse type of distortions, there are several types of distortions. You can compare your upload of Memphis Slim Sassy May with my upload here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BHKvqQLA7Cg.htmlsi=odaxca-oiFQgPyBV The Lenco B52 is as good of a player one ever need, anyhow for newer 78's. 78 rpm records has a much higher "power" than 45 or 33 and cartridges transmit a much higher vibration to the tonearm and resonanses are inevitable in variouse frequency range. The B52 comes in mark 1-3. the early model, light grey has a tonearm with knife bearing suspension sitting directly in the plastic housing and the later model, dark grey has the knife bearing seated in a rubber seat in the housing. That later model is more suitable for 78 rpm. The rubber seats will make the arm "floating" and it will dampen the high frequency resonances. An early 'MK1 can be upgraded by putting a 0.5 mm thin rubber "mat" under the knife bearing and some distortion is deleted. Later Mk3 might have a problem if rubber bearing has dried and cracked but new rubber bearings can be bought. Next is the cartridge, your stylus is mor or less exact the dimesin of bottom of the groove making it "bottom out" if the record is slightly worn. I guess it will work on records in very good conditions but not so good on worn records. stylys is dragging in the bottom, leads to noise. Shure has complete cartridges like the M78, or just the needle HW1 which i think would fit your M-75. They both have a stylus of 2.5 mil equivalent to 65mu which will fit more or less all 78. Exept for the very worn records were you would need to go up to 3 or 4 mil. correct stylus will delete more distortion and noise. The next issue is that some records are so high recorded that they need some extra vertical tracking force to not sound distorted in high passages ike a trumpet in the beginning of the record. The problem with suspensions in your Shure cartridge is that you cannot exced a specific value and there is only so much the cantillever suspension will allow you to push down before it goes silent. The M78 cantillever suspensions can take more, up to 3-4 gram. Unfortunately, high recordings in the start of the record or slightly warped record would require much more, 10 grams or more and there is just no way to make that happen with any of the converted stereo cartridges. One would need true mono cartridges for that. Guess that staying away from excessivly worn, warped or too high recorded records will also work. Good thing about the Lenco is that you can have several headshells and prepare one for 78. I would say this record is contemporary (1955) with the record you want to play ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DB0OX7hXXmk.htmlsi=gvKGEX1oODefONIo This is a good example of high recording but no resonances. If you just want to replace your cartridge without modifying too much one alternative could be the General electric VR serie or VRII which "cdbpdx" uses on his uploaded 78's, work well but gives a reduced low end if a preamplifier has the 47k load resistance. Bass respons is somewhat of an issue after all the distortions are dealth with. some people says the GE are thin but this video shows how much basa a GE VR cartridge can deliver: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FaYgtxkr6kE.htmlsi=UBlsa3CfULgz-vru and that will fit directly to your Lenco headshell. Hope this is of some help.

I’m not familiar with the musikmaster 511, is it a newer or older player? Your Shure pickup is a stereo-type cartride and works fine playing diagonal cut mono (later years) records. For lateral cut i recomend a true mono cartridge and the audio technica at3mono sp is such a cartridge. It should not give an output signal for vertical movement. The SP can have a high, or relatively high vertical tracking force. What could perhaps be considered is the tonearm compliance which is 3-4 times lower than for ”normal” stereo cartridhes. The stiff suspension of cantillever is positive but transfer more energy to the tonarm and it’s bearings. If you can find specifications for your tonearm it should be able ti handle values down to 4-5 10^-6 nm. The SP has a compliance value of 3.5. If your arm is of older type, sturdy and hevvy, it shoud nit be a problem. If it is lightweight and flimsy you could get problem with distortion. You can hear that quite often in youtube uploads of 78 were to light tonearms are used. The output of the SP is high 1.2 mV for a MC cartridge but still low compared to a MM(~5mV).You still need a preamplifier to get a ”RIAA” equalisation but probably you do not need a SUT, step up transformer which otherwise is reccommended for MC cartridges.

Thanks for your answer..! Musicmaster is a Japanese semiprofessional turntable build at 1965 for 78rpm more,the tonearm is heavy and long so if i learn correctly ,for all the 78rpm mono cartridge is a must...
