| Most desirable vacuum tubes for SET amps What do you think about OTL SET amps/integrateds, and the most desirable triode tube in that instance? (I have a Vinnie Rossi L2iSE).When you eliminate the output transformer, you eliminate with it the reason to have an SET. Its the way the SET... | |
| Upgrade capacitors in tube amplifier? There are three coupling caps. The first is at the top of the photo, one in each channel. To the far left and right beside the power tubes is a small circuit board; the coupling caps for the output tubes are mounted on that circuit board; they sho... | |
| Filter capacitance-how does it relate to amplifier performance? My understanding of capacitors is that they store energy. Does this mean that my Due amplifier is just as powerful as the on paper more powerful Atoll in300?No. It just means that the energy storage for the output section will have less noise s... | |
| Subwoofers down-firing or side-firing? Why? The Sub-x sub from Golden Ear has too side firing active drivers and a top and bottom firing passive radiator. Its much easier to get the placement right. | |
| Devore Fidelity Orangutan O/96 My O/96's sounded ok but not quite "right" when paired with a Pass XA30.8. However when I moved to a Line Magnetic 805ia 48W SET they simply came alive, especially when set a no negative feedbackAs is stated in the article I linked from our web... | |
| Who's using Harbeth with tubes, what speaker model and how many watts per channel? most harbeths are nominally 6 ohms, dropping to just above 4-5 ohms in the bass regionmy understanding is that tube amps typically have trouble delivering a lot of current (certainly compared to ss amps which happily double their delivered powe... | |
| Problem with phono stage It looks like Raul is on a roll again. There is some possibility a post of his will be removed, so I will not quote it. Instead I will generally address some of his benighted comments.The calculator I linked to demonstrates that an electrical reso... | |
| Help me understand "the swarm" in the broader audiophile world Does the swarm system work equally as well for home theater and music listening? @jdlynch Yes. | |
| Devore Fidelity Orangutan O/96 Regarding the o/96; I've seen this speaker work quite well but in every case its been paired to a tube amp with a fairly high output impedance (IOW no loop feedback).Speakers that work with that sort of amplifier tend to operate on a slightly diff... | |
| 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. |
