| Thunderbolt Pagoda LP now available Our second LP has been issued on New Ruins Records, available through Mutant Music and Chicago Independent Records.Again it is an all-analog recording, 150gr vinyl mastered at RTI. We used refurbished Western-Electric mic preamps run direct into t... | |
| Why Use Aluminum for a TT Platter? Copper is the best for platter top!There are problems with any metal for being the top of a platter. The top of the platter should be available as a means of damping the vinyl as it is tracked by the tone arm. Metal is ill-suited to this task.Copp... | |
| A Copernican View of the Turntable System At low volume levels its not that hard to get a 'table to sound good. Its at high volumes where the rubber hits the road. IMO, the turntable should be unassailable at any volume. I found that once I had sufficient mass and rigidity in the plinth, ... | |
| What amp are you using with your Zu Essences? Audiofeil's comment about OTLs and ZUs is incorrect. There don't seem to be any OTLs that will not drive the 6 ohm ZUs quite well. | |
| Relate sensitivity/impedance to speaker efficiency Nnck, First lets look at the two options as if they are both on the Power Paradigm (efficiency, 1 watt 1 meter).Under this model the Acoustic Zen is 90/91db. The other speaker is 84/85db if it is also 4 ohms. If you want a tube amp the latter is g... | |
| Lightspeed Attenuator - Best Preamp Ever? Jult52, you have no worries, in fact this is more of an ideal situation (so long as you can get the amp to make satisfying power)- you *want* the amp to have less sensitivity than the maximum level of your source, as this allows you to run the pas... | |
| Nice Tube Preamp for Boulder 1060 Depending on the length of your cables you have a variety of preamp choices. However the balanced line system was conceived with the idea of eliminating audible differences between cables, so if it is done right, length is not an issue either.Most... | |
| Ground loop b/w amp and phono stage This is a temporary fix, but try getting an AC ground cheater from the hardware store and put it on the AC cord for the phono section. It may be that the phono section has its ground connected right to the wall, which means you have a ground loop.... | |
| A Copernican View of the Turntable System Dgob, any resonance in the arm tower will be a coloration. If the feet prevent the tower from coupling to the base of the platter bearing, that too will be a coloration. | |
| Why Use Aluminum for a TT Platter? I had a Technics SL-1100. I think it had the distinction of being the first DD machine made. It also had the heaviest platter of any DD machine, including the SP-10 and certainly heavier than any Dual, Garrard, Thorens, or the like. The 'cogging' ... | |
| Relate sensitivity/impedance to speaker efficiency There are a couple of other things to consider, in addition to the points that Al makes. some are here:http://www.atma-sphere.com/papers/paradigm_paper2.htmlAs I understand it though, both speakers are friendly to tubes. However impedance plays a ... | |
| Amp s choices to match with Wilson Sophias ? The Wilsons have always been tube-friendly. So you have a wide range of tube amps available for the speaker as well. | |
| Why Use Aluminum for a TT Platter? Aluminum is used for several reasons. The first is that it is non-magnetic. This keeps it from messing with the cartridge. Aluminum is also relatively cheap, as it is one of the most abundant metals. Its also easy to machine.An aluminum platter sh... | |
| Oh how I wish Class D amps ... Mapman, if a tube amplifier is fully-differential from input to output, it will not have even-ordered harmonics- they will be canceled at every stage throughout the amplifier. The even orders show up when part of the tube amp is single-ended. With... | |
| Magnetization & Demagnetization any conclusions? K_brown, the Classic Quietex clear vinyl was made specifically so it would not have magnetic noise, since the 'magnetic noise' is supposed to have something to do with what makes the vinyl black.So these demag thingys should have no effect on the ... |
