| Desire to try tubes The use of any SET requires careful speaker selection. This is because even a higher powered SET will have a fairly high output impedance. For more information take a look here:http://www.atma-sphere.com/en/resources-paradigms-in-amplifier-design.... | |
| DSP TO TAME THE BASS IN HARBETH SPEAKERS There is no problem with my Hegel H590 or Class D Audio SDS 470C amps, just my ARC Ref 150se. So... it's not the room... its the amp.You might know that I'm a tube amp manufacturer (that also holds a patent in class D amps as well). Take it from... | |
| Problem with phono stage So the low capacitance cable as the first step is now, a page and a half later, shown to be correct. You can easily hear a peak at 17KHz as it influences an envelope of frequencies about it, going down to about 10KHz.A gentleman with deep knowledg... | |
| Do you use a Subwoofer when listening to stereo? The problem is that the room has a dimension and bass waves will reinforce at certain frequencies and cancel in others. So unless your bass traps are actively able to move about the room as the bass notes change they will have little effect. DS... | |
| DSP TO TAME THE BASS IN HARBETH SPEAKERS which is primarily the result of room issues and secondarily related to the more limited control by tube ampsWhen you have bass problems in a room, the number one reason is standing waves. These cannot be controlled by DSP or room treatment.The pr... | |
| I'm never going to hear a megaspeaker in a good room am I? I'm never going to hear a megaspeaker in a good room am I?Not unless you go into one. | |
| DSP TO TAME THE BASS IN HARBETH SPEAKERS to tame the bass bloat in my Harbeths when driven by tube ampsWhat amplifier and what Harbeth? This might be solved in a simpler fashion! | |
| Problem with phono stage The actual inductance is not listed on the Nagaoka website. Naturally I looked there first, but since Raul suggested the value first, I used his numbers (600mH) but sensing that was probably too high gave him the benefit of the doubt and went with... | |
| 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... |
