| Looking for a Tube preamp with Tube Rectifier stage <= $/£/€ 3000 Just a FWIW: there is no good argument for a tube rectifier in a home audio preamp. The reason is simple- the only real advantage of tube rectifiers is that they are lower noise than solid state, if the solid state rectifiers are not treated corre... | |
| What is the best preamp for Carver monoblock tube amps? Which model of Carver? Do you know the input impedance?Other than being able to drive the input impedance, the correct answer is along the lines of 'the preamp that you like the best'. | |
| Tube Fire What Next? Actually the tube arced. This usually happens when the tube has aged out, or has been damaged. The usual culprit is a sort of paint on the cathode of the tube, which can flake off, and it is conductive. This is the genesis of the arcing. I would r... | |
| High end Class D amps? Class-D wattage instead of doubling for each halving of impedance load actually gets goes backwards when they see 2ohms and worse if there is any - phase angle involved, because they can’t deliver the current like a good bi-polar linear Class-a... | |
| Preamp recommendation What is your budget?Do you want single-ended or balanced? | |
| vinyl versus digital redux Analog tape is not a panacea. Just like vinyl, it significantly colors the sound.To be clear, analog tape colors the sound more than the LP, owing to the fact that a properly functioning tape machine will exhibit a 3rd harmonic, which contributes ... | |
| Class D Technology Bottom line is until we can get rid of the nasty 3rd harmonic distortion in class d our ears will always prefer the cozy 2nd harmonics that tubes generate@kw6 Actually the human ear/brain system treats the 3rd harmonic the same as it does the 2n... | |
| Resistive loading Most modern cartridges have their peak so high up, there is no need for loading to tame the peak, as far as frequency response is concerned, but loading may help with some phono stages that are not equipped to handle the ultrasonic peak overloa... | |
| TONEARM DAMPING : DAMPED OR NOT ? ? USELESS ? ? WELCOMED ? ? Merely being able to play an LP side without skipping or obvious distortion is not itself proof of good tracking.An oscilloscope has been indispensable in our mastering operation. Test equipment can be quite handy for moving from anecdote to more ... | |
| Is this possible? I was under the impression ( maybe mistakenly) that one needed at least some kind of phono stage due to the RIAA requirement to utilize a SUT. You need a phono section with RIAA eq to use any phono cartridge using a magnetic operating principle, ... | |
| Hi end tube preamps, it’s all about functionality!! Bet it will sound better than any "high end" preamp.The value of the bet being how much you paid for this... The 6BL7 is a nice tube, but with only one the circuit possibilities are limited. But in the right situation it should sound quite nice. | |
| Any high end preamps out there where tubes off while HT in use? Any high end preamps out there where tubes off while HT in use?Why would anyone want this?? You'd have to wait an hour or so for the preamp to sound right if you wanted to use the 2-channel. | |
| Audio Research Amplifier Balanced Input Question ralph can this be done just with passive components?Yes- the Jensen transformers I mentioned. This is the part needed:https://www.jensen-transformers.com/product/pi-2xx/There are several versions- the one needed has XLR and RCA connections. | |
| Receiver recently repaired - Now producing fuzzy distortion in higher frequencies?? I suspect that the bias diodes used to give thermal feedback from the heatsinks are shorted. This will cause the amp to sound exactly as described. It causes the amp to have extreme crossover distortion. I would take it back to the service shop an... | |
| Class D Technology @noble100 OK- I just wanted to be clear on what was meant by 'switching distortion' since that's not an engineering term at all!Artifacts from dead time show up as harmonic and intermodulation distortions, so a class D amplifier can easily be comp... |
