| What tubes for sibilant SET Triode amp So your amps make about 12-15 watts- that means the Gallos have to be about 102 db to really take advantage of the amplifier's capabilities, and I don't think they are anywhere near that! So my guess is you are pushing the amp too hard to let it s... | |
| current versus watts Hi Dob, I agree keeping distortion down is important. Distortion can hide detail. A lot of designers use global negative feedback to reduce distortion though, and this technique often results in subtle enhancement of odd ordered harmonics, specifi... | |
| current versus watts When we are talking 'best', IMO power doubling has nothing to do with it; none of the 'best' amps I have heard have that capability.I feel that the specs have no meaning if the resulting amp is unlistenable. IOW our ears are more important than th... | |
| What is meant by a "fast" pre amp Agreed- 'fast' by itself would strike me as being a coloration. 'Fast' with a host of other aspects (detailed, transparent, **relaxed**, wide bandwidth), no worries. | |
| Amp/ preamp for electostatics and why Rrog, do you mean you are surprised that I recommended one of our used amps rather than a new one? Its true that I avoid direct recommendation of our products, even when I think the recommendation is warranted. However ESLs together with OTLs have... | |
| Empire 208 turntable IMO the 208 is the one to mess with because you can put a modern arm on it. We did so much tweaking to it we finally even made a new plinth for ithttp://www.atma-sphere.com/products/208.htmlIf you want a simple effective tweak, get rid of the 45 r... | |
| Tri-Planar grounding question... Dogpile, my setup is balanced, but the wiring is identical up to the box in the cable. The Black wire is the shield up to the box and connects to the tone arm ground itself. After the box, the black wire breaks out to its own connection, and ties ... | |
| Amp/ preamp for electostatics and why A set of our M-60s, using a set of ZEROs to drive the MLs will make 80 Watts at full power, are monoblocks and are fully balanced.There's a used set in the classifieds right now. | |
| Krell amp with Zu Essence speaker If you are new to high end audio And you already have a set of ZU EssencesAnd you have never heard a tube amplifierThen you owe it to yourself to try one out on that speaker!In most rooms with many tube amps they will play as loud as you can stand... | |
| Tri-Planar grounding question... Jeff, I think you got it right. The reason it is not a ground loop is that the only place the ground occurs is the shield of the cable. Without that connection to the arm, the arm would be floating and it would buzz like crazy!This concept is comm... | |
| Designer Hall of Fame Beerdraft, it might interest you that Victor's partner was a customer of ours and had bought 2 sets of our amps and a preamp. I spent a few hours on the phone with Victor while he had one of the amps open on his bench, trying to model it in P-Spic... | |
| Tri-Planar grounding question... The shield does not go through the gimbled bearings. Inside the arm tube, the tube itself is the shield. So the arm ground is usually picked up somewhere near the base, probably very near where the wires transverse the gimbles. | |
| Obscure companies making excellent speakers? Mehrakrishan, no field coil speaker is going to be inexpensive. The reason the permanent magnet speakers showed up decades ago is that they are cheaper to make!The High Emotion Audio speaker is easy to drive but it is not considered high efficienc... | |
| What is meant by a "fast" pre amp 'good phase purity' comes from wide bandwidth/high slew rate.In order to get to 20KHz without phase shift, the upper cutoff of the circuit needs to be 10X higher, IOW 200KHz. YOu can use that as a good rule of thumb for seeing a 'fast' preamp in i... | |
| Tri-Planar grounding question... The two should be the same. |
