| Upgrade capacitors in tube amplifier? I'd be careful about anything that is paper and oil in a tube circuit. Over time its not that unusual for them to develop a bit of electrical leakage; this can throw off the bias and operating points in the circuit.FWIW we've had good luck with th... | |
| Problem with phono stage where normally internal inductance is not really high ( say over 600. ) so with that 150/200 capacitance in the Lehmann and due that has a high overload design seems to me that that is not the problem but Lehmann overall set up.Let's drop these... | |
| Problem with phono stage How in the world are pops and tics not normal in vinyl playback? It’s part of the medium as it is a contact sport so to speak.@audioguy84Many phono stages generate ticks and pops on their own, caused by poor high frequency overload margin, related... | |
| Audible Illusions M3A factory refurbished or MFA MAGUS Bruce Moore checked? I prefer the Magus, but if you are planning to use the phono section, a good number of them have a non-RIAA extension to the equalization that causes them to be bright. Its only two parts in the EQ that get bypassed- its easily sorted out. The lat... | |
| Why I enjoy my Luminous Audio passive unit, vs an additional gain stage ( preamp ) Question : Are there many high end home audio companies whose products offer balanced only, conform to the AES48 standard. I hate to say it but 'no'. Most of the balanced line preamplifier product I've seen that is balanced does not support the st... | |
| Tubes most likely to improve SQ? Yes.Start with the 12AX7- and then work your way forward to the outputs. | |
| Problem with phono stage I thought capacitance for cables didn't matter with a MM Cartridge , only MC.@vinylvin , @emilinActually it matters quite a lot! With a high output MM cartridge the inductance tends to be rather high. This in tandem with the capacitance of the to... | |
| Why I enjoy my Luminous Audio passive unit, vs an additional gain stage ( preamp ) The entire system used during our cable evaluation was new Benchmark products, from the source to the amps, which I understand to be ( prove me wrong ), the standard AES48. And if I am wrong, so be it. I have been wrong before. So, given the " ... | |
| JBL L100 Amplifier Recommendations Its not so much that you need a gutsy amp to drive a 12" speaker; what you are dealing with here is the simple fact that JBL chose to make this speaker hard to drive. Its nominally 4 ohms to start with, and has a difficult phase angle in the mid b... | |
| Why I enjoy my Luminous Audio passive unit, vs an additional gain stage ( preamp ) I am not sure why your insistence of " cables do not sound different ", when they are used in a balanced configuration. Several of us have heard these differences, and easily.......getting back to transformers for a moment. I feel, they are nec... | |
| Problem with phono stage Do I need a special cable for the phono stage?@emilm Yes! Most regular cables have too much capacitance. This causes a high frequency peak and certainly can emphasize ticks and pops. A proper phono cable will have a capacitance of about 20pf (p... | |
| Problem with phono stage Is this a common problem with added phono stages as opposed to integrated onesNo. So let's start with what cartridge do you have? Also, what kind of cable (phono cartridge cables should be low capacitance)? | |
| Why I enjoy my Luminous Audio passive unit, vs an additional gain stage ( preamp ) I have listened to passive units with transformers and find them to be round and colorful, meaning they are warm and the frequency extremes seem rolled of. They are not as detailed to me. Being familiar with pro gear and balanced lines, I still... | |
| Theoretical Pre Amp Question For a tube pre I think case 1 would impart more constant tube character because it is running at constant power and only attenuating after.@cat_doorman The harder you run the tube circuit the more distortion it will make. So its not a matter of... | |
| Most desirable vacuum tubes for SET amps I also have a Dynaco ST-70, also running the EL34 in ultra linear. I love the sound of this amp as well but if I listen to the EL34 in SET triode and then listen to the Dynaco, the Dynaco then sounds very mushy. Is the Dynaco sorted out prop... |
