| Class D Amplification Announcement there is no top sparkle, midrange has never had lively crunch as A or AB no matter how many times you sell your selves they are so awesome, better than class A or AB, ................Nobody says it's better than A- A/B... Really?... | |
| What is the “World’s Best Cartridge”? @rauliruegas @mikelavigne -Look, these are some specs of the Studer A820 that confirms in some ways what you posted and I said here: tape speed deviation: +,- 0.2% - tape slip: +,- 01% . Speed stability here is even more critical issue than in... | |
| Playing with Cartirdge loading on my phono stage does that mean we can just select the load with an o-scope? and select the highest resistant value possible? It would be better to use a distortion analyzer, but this would only be of benefit if the phono section can't deal with the RFI on its ... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? If tips from phono stage manufs including Jud @ Joule-Electra(RIP), Kevin@K&K and everyone here couldn't resolve it, it was time to move on. @sbank If that was a JE phono section, the input gain stage was so starved for current that it eas... | |
| Added an SUT...not sure I understood this the industry standard of 47kΩ was adopted from the MM cartridge world and applied to the MC realm because is first and foremost "does no harm".... until you throw a SUT into the mix that is. Once a SUT is added the load the cartridge can see can... | |
| Playing with Cartirdge loading on my phono stage Would it not depend on the frequency response of your speakers in your listening room with your tastes for sound in mind? No. The reason the sound changes is due to distortion- LOMC cartridges and the tonearm cable together form an electrical r... | |
| Class D Amplification Announcement Ralph, could this have been possible without the GAN ? If so, why wait so long ? Yes. There's a lot of noise around the 'sound' of class D amps on the internet (IME class D amps can vary in sound quite dramatically, more so than the sound of va... | |
| Class D Amplification Announcement The reason why I think more manufacturers will be using their resources in developing Digital and even lower cost Class D amps is in part due to the energy efficiency. The reason we did it is because the switching nature of the class allows the... | |
| Added an SUT...not sure I understood this Do you not think the cartridge designer and manufacturer knows what they are doing when they recommend a minimum of 100ohms ? They know that the designer of the phono preamp may not have taken the RFI generated by the cartridge and tonearm cabl... | |
| What is the “World’s Best Cartridge”? Regarding field coil ps variables @atmasphere has posted in the topic. Maybe he can help us here I doubt it. I'd be very concerned about adding the wires needed to power the field coil. They would have to stiffen up the arm since they would hav... | |
| Added an SUT...not sure I understood this Again: getting to the bottom of the hum thing might be a good idea too. SP-14s are older ARC preamps if memory serves (and a quick search says it was introduced in 1989...) - when was the last time the filter capacitors in it were replaced? If t... | |
| Added an SUT...not sure I understood this @lewm is right and so is @dover . At this point IMO the thing to do would be to get someone to remove those 100 Ohm resistors. SUTs are usually designed to drive 47KOhms (although Jensen makes one designed to drive opamps that expects to see 6.8K). | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? @filipm OK. That's 99 44/100% the EAR is at fault. What happens when it is not running off of the battery? | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? I would make sure the EAR is grounded via the power cord. @filipm That it makes more noise with the inputs shorted is telling. Of course you are living in a high RFI zone; that is why everything works fine elsewhere. Could you clarify this com... | |
| Cartridge Loading.....Part II Plus, db are units expressing the ratios of voltages, having nothing to do with current. Anyone? DeciBels refer to voltage, yes. The higher gain settings must invoke downstream gain stages that add to signal voltage output by the indicated db... |
