| Cartridge incompatibility, Soundsmith and Luxman Dave, the Luxman website page on the 590ax2 ( not the 250 or 500) indeed gives very little useful information regarding the phono section, but the many photos of the many PCBs reveal no evidence of a SUT anywhere. Furthermore the unit seems built ... | |
| Cartridge incompatibility, Soundsmith and Luxman The fact that the sound seems rolled off in the treble to you suggested that the relatively high inductance of the cartridge, compared to that of a typical LOMC, is causing a loading issue, as Atma-sphere just showed us. This was mentioned in my p... | |
| Cartridge incompatibility, Soundsmith and Luxman I looked at the specs for both the Zephyr Star and the Luxman 590. There is no obvious reason why this pairing cannot be made to work well. First, I don’t understand quite why SoundSmith recommends a 470 ohm load for this cartridge. It’s internal ... | |
| Would you pay more than 25% of MSRP for a used cartridge? Here’s where everyone trots out his or her individual experiences buying used cartridges. As to the issue of cost, I forgot to point out that many cartridges that are out of production are now valued much higher than their original MSRP. For those... | |
| Would you pay more than 25% of MSRP for a used cartridge? “Caveat emptor” is good advice for probably more than 2000 years. “Trust but verify” also is a good motto. Get a pre-purchase inspection done by an expert. If someone like Peter Ledermann or our Needlestein confirms low use and perfect structure. ... | |
| Stylus force digital scales Good olde 2013. | |
| How do you tell your Cartridge needs replacing? The OP owns a Sumiko cartridge, not an AT. So unless Sumiko offers a similar service to AT, the OP is best off procuring the services of an independent repair shop like the ones you, and several others before you, named. | |
| I am enjoying my analog system, but what can I do to improve? Pindac, I apologize if I sounded harsh in my last post. Anyone can say anything about how any two components sound in a side by side comparison, and your report is one example. There’s no right or wrong conclusion in that context. I just disagree ... | |
| Linear Power Supply? The LPS perhaps keeps the platter spinning a bit longer because its capacitors hold charge for several seconds after unplugging the unit. Until the DC voltage falls below a certain threshold, the platter will keep spinning. No magic. | |
| How do you tell your Cartridge needs replacing? Not many of us have the skills and experience to determine by inspection the condition of a stylus except in the most severe cases of wear, even with a microscope designed to do the job. I include myself as lacking such skills, and I do own a suit... | |
| I am enjoying my analog system, but what can I do to improve? Pindac, What you reported is "hearsay" evidence, you reported that someone else reported that he or she preferred his or her modified SP10 Mk2 over the SP10R. Here’s another opinion: I find it hard to believe that any SP10 Mk2, no matter how modif... | |
| Linear Power Supply? I'm sorry. Where did I "deny" anything? I simply pointed out that the OP is concerned about replacing a wall wart that contains an entire power supply, which launched a discussion of switching power supplies (SMPS) vs "linear" power supplies (LP... | |
| Linear Power Supply? Viggen, Sounds like in your case the wall wart WAS a transformer, only. That’s different from the situation under discussion where the wall wart is a complete power supply, meaning a transformer plus the downstream parts required to generate DC at... | |
| Linear Power Supply? I am not knowledgeable enough to concoct an explanation for why a tube based motor controller might outperform a solid state one, for performing the function required in the Brinkmann system. But I do know that such a rationale exists somewhere, ... | |
| Linear Power Supply? Like I said, it's a matter of individual perception. Is there likely to be a measurable advantage to the LPS vs the existing SMPS, in terms of noise in the audio signal or speed control accuracy? No, I don't think so. But will you hear a differ... |
