| 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. | |
| current versus watts Sound quality has little to do with current (otherwise the tube industry would have died decades ago) and has everything to do with distortion. That is a topic for a different thread.'Current' is an issue about which there is a lot of mythology. s... | |
| Tube Testing: Is Measuring Plate Current Important The Hickoks are good testers. Usually you don't need plate current to test the tube, but you should understand that tube testers like the Hickoks, which are called transconductance testers are in fact an approximation. But they are usually much mo... | |
| sweep tubes and audio application? The 6LF6 was used by Futterman in some of his OTLs. They have high-current low-voltage capability. They have become rather expensive as they are no longer made.These days the EL509 is the tube that replaces the 6LF6 although not directly. It is a ... | |
| Are linear tracking arms better than pivoted arms? The idea that a pivoted arm of correct effective mass is going to induce greater side-to-side excursion than an air-bearing straight-tracking arm strains credulity. |
