| Different amplifier class for different music genres? Sorry, meant to write 1kHz signal, not 1mHz.enjoy | |
| Different amplifier class for different music genres? The amps should indeed sound different anyway. Different design and circuitry. However are we comparing apples to apples.Are we swapping one amp for another in the exact same system (changing absolutely nothing else) and listening to the same mus... | |
| Different amplifier class for different music genres? Ralph (Atmosphere) is correct. An amplifier is designed to amplify the input signal with expected 100% accuracy. It is designed to operate with a flat frequency response over the stated frequency range into a designed for load.There are other cr... | |
| Power conditioner types I know PS Audio (I believe) offered power regenerators. Very large heavy units. I tried a unit several years ago, no longer in production and it was nice. However, my current power conditioner made my system sound better. I'm sure the current ... | |
| Power conditioner types I believe that the OP has the answer to the original question. Some conditioners recondition the power. IOW, they take the AC input voltage and current, convert it to DC, then convert it back to AC with a now fixed voltage and frequency that won... | |
| SOTA NOVA, HR-X VPI, Technics 1200G recommendations? This is a fascinating post. I am quite enjoying this. thanks allFor a newbie (I am definitely not one), this would be daunting. I imagine this turns off potential turntable/cartridge/tone arm/phono stage buyers.It reminds me of that old Saturda... | |
| An unconventional approach to POWER MANAGEMENT I am an Electrical/Electronics Engineer with experience in analog/digital design, amplifier design, computer design and also a state registered power engineer.So, yes, I'm one of those. Rattling of code is not a negative. people that ignore loca... | |
| why did my record player slow down, speed up, then go back to normal? There are also apps on line that provide for your cell smart phone to do this same check.It is interesting.Apps such as RPM, Rotor or true note.enjoy, | |
| why did my record player slow down, speed up, then go back to normal? If it is a table with no fixed speed controller, it could have been a surge or power change in the system temporarily. in other words, if a large load came on-line in your area, the frequency would changes for a very short time so that additional... | |
| What’s the relationship between gain (dB) and power (watts)? Look at it this way.A Designer has design requirements.Design an amp that produces 250 watts per channel with an input of x mV into an 8 ohm load that will produce the 250 watts per channel max without clipping. an input impedance of y Ohms, outp... | |
| Arrangement of components on rack Four things that I try to be mindful off in arranging components.1. Turntable on top and away from transformers or any component that can contribute EMF or noise, such as power supplies or power conditioners, to very low level components such as c... | |
| Uber expensive repair at United Radio @dasign I get you.However, knowing/diagnosing what area in an amp is the problem is not the same as knowing what circuit(s) is the culprit.I can determine that the protection board is the problem, but, unless (like most repair shops), I replace th... | |
| Uber expensive repair at United Radio A lot of very good points made by many here. Very good posts.As some mentioned, exactly how long does it take to diagnose where exactly the problem is? That actually takes more time than pretty much anything else. The OP mentioned two chipsets.... | |
| SOTA NOVA, HR-X VPI, Technics 1200G recommendations? If it was my choice between the listed turntables, I would send the Sota back to the factory to be checked and upgraded. That is an outstanding turntable. Second would be upgrading the arm to possibly a SME IV or V.But, for the price range liste... | |
| Upscale Audio and Primaluna Kevin; Thanks for the insightful response. Good to know. enjoy |
