| Review: Aidas Mammoth Gold mk2 MC cartridge >>"As mentioned in the review, the use of ivory by violin and guitar makers says a lot about its resonance characteristics." But exactly what does it say? This is a transducer, not a musical instrument. The only thing advantageous about ma... | |
| Review: Aidas Mammoth Gold mk2 MC cartridge Here's what Aidas says: "28db or more at 1khz ( channel separation) , Channell balance ＜ 0.4dB 1khz. " | |
| Review: Aidas Mammoth Gold mk2 MC cartridge >> I cannot find performance specs related to precise imaging channel separation ______db? channel balance _______db? << I will try to find out for you. | |
| Review: Aidas Mammoth Gold mk2 MC cartridge >> Given that mammoth ivory has hardly been extensively studied for its sonic properties, I assume a cartridge body made from it is made for the same reasons I have three custom straight razors scaled with it: it looks pretty and it confers ... | |

| Record Cleaner Advice? Good for KL owners to know, Bill; thanks. That said, it does not allow you to access the actual bath where the water and record meet. And that's where the gunk accumulates.I wonder if multiple ultrasonic cycles, each with clean water and no re... | |
| Record Cleaner Advice? Distilled water is certainly cheap enough in the States to enable you to change out the water constantly, but you’d probably have to clean the inner walls of that container (and Lord knows what the innards involve in terms of removing any surf... | |
| What about Uni Din? I also use the UNI-Pro version, the big brother to the SMARTractor.I like it. It works well for classical works that have complex climactic third and fourth movements. .Here’s Fremer on UNI-Din playing off an excellent chart from Wally Malewicz. B... | |
| How to choose the right protractor for my effective tonearm length Although the question I'm really trying to ask is how do I know that a protractor is right for my turntable other than the advice of anyone telling me use this protractor or that protractor. How does any given protractor achieve the correct o... | |
| Best ultrasonic lp cleaner in 2020 and what surfactant best? Triton X-100 contains compounds with aquatic toxicity and is being phased out by the EPA. Recommended alternatives include Tergitol 15-S-9 or Ilford Ilfotol. Tergitol 15-S-9 requires less concentration to do the same job as Triton X-100, which mea... | |
| Honest question about cartridge vs. turntable performance. To my way of thinking, the turntable is the analog system’s clock: it creates the time in which the source signal comes to life and exists. If the event at the nexus of the stylus and the moving groove does not occur at 33 1/3rpm, no downstream fu... | |
| Thumbs up for ultrasonic record cleaning @terry9 Your example of particle size is unconvincing to me. A ’visible glop’ is made up of tiny particles which can be broken loose by US action, and then either deposited as solids or taken into solution as solutes, or perhaps even suspended. I... | |
| Thumbs up for ultrasonic record cleaning @antinn Thank you for your interest in this topic and your contributions.Fwiw, we are talking about units costing more than $2k. At least I am; I don't know what Terry9's machine cost.. I tried the cheap Chinese route and it proved unreliable.If ... | |
| Thumbs up for ultrasonic record cleaning I also see that you are cleaning 6 records at a time, which means a spacing of at most 33mm. That spacing is OK for 80KHz, about 1.7 wavelengths, but, at less than a wavelength, that spacing is quite inadequate for 37KHz. Also, with 6 records ... | |
| Thumbs up for ultrasonic record cleaning @jtimothya Don't see why a mixture of frequencies should be better. There was a graph posted in the DIYAudio thread of cleaning efficacy vs frequency. For gaps the size we see on records, 40KHz is only marginally superior for the largest gaps... |
