| Red Plating?? To drop the AC line voltage inexpensively you can use a device called a bucking transformer. This is simply a transformer that has the required voltage (10V) along with the current required. So if the amp is drawing 3 amps you could use a 5 amp 10... | |
| Red Plating?? @georgehifi When you go from an autobias to adjustable (by definition both are considered 'fixed bias' as the bias is 'fixed' by the voltage on the grid), regardless of how the amplifier is biased, the output power is unchanged (the distortion cr... | |
| Class D It’s more about power, because you can’t see the forest for the trees, with what Mark Levinson tried to do by series up "low order" output filters (so they don’t burn out) and trying to get a steeper roll off as not to introduce phase shift int... | |
| AES48 , is there a test to determine? I have determined that my DAC and amp do not support the AES48 standard.If that is the case, you may not be able to run cables long distances and you might run into ground loop issues. But if there's no ground loop (which is entirely possible) tha... | |
| Tube amp Friendly Speaker That Sounds like Klipsch Cornwall I'm guessing budget plays a role?I run a pair of Classic Audio Loudspeakers model T-3. 16 ohms, response to 20Hz, 98dB 1 watt/1 meter. 60 watts is plenty of power on them in most rooms!You might consider another alternative though. If you were to ... | |
| Never Owned a Tube Amp and Want Advice @dsper Ask him if he can wire the woofers in series rather than parallel. It will require a little bit of adjustment in the crossover but otherwise the math of the drivers in the box is exactly the same. Contrary to popular myth, the woofers will ... | |
| Red Plating?? Would you consider the red plating shown in my photo a "bit"?@chinook9 Technically this would qualify as 'a bit' :) It would certainly have me nervous! I would contact the manufacturer of the amplifier. | |
| Class D The amount of power the filter has to contend with in Class-D amps compared to a dac, now your showing how ridiculous your statements are.This statement is wildly incorrect! Although digital and class D amps both employ switching, it is important... | |
| AES48 , is there a test to determine? It was partially your high opinion of the HPA4 that lead me to try purchase one. Since the HPA4 is AES48 even though it has both balanced and single ended outputs without a switch (please comment Ralph)Without a look under the hood I suspect tha... | |
| Modern amp solution for Magnepan 2.7QRs with bluetooth and phono stage interfaces? If you get separates, which often work better with Magnaplanars, then what you need would be a power amp for the speakers, and the bluetooth and phono functions could be handled at the preamp level. But any preamp would do fine if a bluetooth rece... | |
| Red Plating?? Interesting, the manufacture designs an auto bias amp around the kt88 tube and then recommends the user to use 6550 tubes. Functionally they are nearly the same. No-one makes 6550s anymore; KT88s work in all the same places. But a 6550 will be a v... | |
| Class D No because it's only to get the low order output filtering on the speaker output up high also, so then you can get rid of "all switching noise" without effecting the phase integrity down into the audio band. This has been explained ad nauseum; t... | |
| Speaker sensitivity vs SQ There are a lot of examples when amplifier has mixed SE and PP stages.For example some SET amplifiers have first stage SRPP and PP amplifiers have SE first stage before phase spliter.Another example - SE preamp and PP amplifiers.Do all these ampli... | |
| Class D I don't see anything in Cyrill Hammer's bio that would suggest the extensive knowledge in signal processing or advanced control theory or even ultra high speed switching for analog reconstruction that would make his opinion any more valid than ... | |
| AES48 , is there a test to determine? Yes. If you have an amplifier with a single-ended input, use an XLR adapter that connects only to pin2 and pin1 of the XLR output of the preamp. NOTE: pin 3 should **not** be connected for this test. Connect to the amplifier and listen to the resu... |
