| Break-in period for an idle but used MC cartridge? No, I really can't. I do it empirically, except to say what I already said, mistracking is a sign that the suspension may have stiffened up during storage. If increasing VTF to max recommended value cures the problem, then I assume the problem w... | |
| Break-in period for an idle but used MC cartridge? I do one or both of two things, when installing a used MC that has not been exercised in months or years: (1) Set VTF at the upper range of recommended for at least a short break in period, especially if you detect mistracking at a VTF midway betw... | |
| Denon DL-103 Compatibility To any of the above, try a high quality heavier headshell, like the Ortofon LH9000 or the AV101 Orsonic, and I think you’ll realize an improvement, even though you’re presently satisfied. It’s not only about the resonant frequency equation. | |
| Step Up Transformers….Are they Worth the Trouble? For the very lowest output MC (Ortofon MC2000), Dave Slagle built me a head amp which I couple with my very much tweaked tube-rectified and tube voltage- regulated Silvaweld phono stage. This combo is the best sounding of 3 possible ways in which ... | |
| Garrard 301 - Project Where is the completed Garrard TT going to go, in the context of the overall system photo? Also, I don't see amplifiers or speakers in your equipment list. Everything you own is pristine and a treat to the eye, including the room itself. You're ob... | |
| Phasemation cart on Technics As long as the tone arm effective mass and the cartridge compliance are not wildly mismatched, I personally tend not to worry about that issue too much. For one thing, we never can know the actual compliance of a given sample of the cartridge. All... | |
| Phasemation cart on Technics By the way, you seem to be conflating weight with compliance. At least the numbers you quote look like compliance data. But yes, for a low compliance cartridge, like yours seems to be, you want a tonearm with high ish effective mass ( not “weight”... | |
| Phasemation cart on Technics It’s only 5 hours old. It feels like you wanna send your baby for a facelift already. Give it at least 50 hours to break in. Also, the new suspension is usually a bit stiffer, lower in compliance, than spec. For a few of those break in hours, you ... | |
| Grado Statement 1 The thread is 14 years old, but apparently you can still buy the Statement 1 from LP gear. Its output is only 0.5mV, so you do need around 60 db of phono stage gain, depending on ancillary equipment. The internal resistance is only 2 ohms, but as ... | |
| Phono Preamp Gain You cannot really extrapolate from one system to another to estimate the needed phono stage gain, especially if the line stage is passive. But amplifier input sensitivity, and speaker efficiency also play important roles. Anyway, the OP cannot bre... | |
| Discuss The Viv Lab Rigid Arm Yes, I think it makes sense to assure that the single null point falls somewhere on the playable surface of the LP, and for many reasons known to both of us, it seems a good idea to place it nearer to the innermost grooves than the outermost groov... | |
| Discuss The Viv Lab Rigid Arm Raul, I have more or less done such experiments already. The only way to get any null point on the playing surface of an LP, with the Viv or any other tonearm that has zero headshell offset, is to mount the tonearm with underhang. If you mount the... | |
| Discuss The Viv Lab Rigid Arm The cause of friction is gravity, in this case.. | |
| Discuss The Viv Lab Rigid Arm Raul, I agree that a strain gauge used without any correction would not conform well to RIAA, because it would not be correct in the region 500Hz to about 2kHz, where the RIAA curve has a plateau. But like you said, because we don't know the ident... | |
| Discuss The Viv Lab Rigid Arm Pindac, in your recent very long post, I am not quite sure what you wanted to say, but I take it that you believe the pleasure of good music enjoyed in the company of good friends is the highest goal of our hobby, and who could possibly disgree wi... |
