| Tonearm mount on the plinth or on Pillar ? This statement is unexpected and seems counterintuitive, at least to me. Could you describe the tables measured? If you've seen photos of Halcro's TT101, do any of the measured tables reflect that level of isolation?Could you please list all th... | |
| Speltz Zero Autoformer with Tenor OTL 75 I live in the twin cities and nobody uses Atmosphere amps on maggies.I heard them once connected to maggies at the dealer, and they sounded poor, IMO. The store owner said they were a poor match.I do not see the advantage of a 2 MHz bandwidth on t... | |
| Direction of aftermarket fuses (only for believers!) As an IEEE engineerGoogle failed to answer me on this- what's an IEEE engineer? | |
| Half speed records, are they any better ? things like tape damage and edits become much more noticeable as they basically take twice the amount of time to pass over the tape head. These things can "stick out" on playback whereas they wouldn’t on a conventionally mastered LP.On the othe... | |
| Tonearm mount on the plinth or on Pillar ? Anyway, stand alone tonearm pod or not in both " configurations " exist distortions of many kind. Wich configuration puts us nearer to the recording?, this's the question and main subject. This is actually easy to measure! We do it with a silent... | |
| Dual Differential / Balanced? ^^ The 600 ohm resistor was used in the old days as a termination device that ran double duty. Part of it was to keep the impedance low such that cable artifacts were swamped by the low impedance. The other part was that the output transformers us... | |
| Speltz Zero Autoformer with Tenor OTL 75 The advantage an OTL driving a set of ZEROs has is that the ZEROs don't limit bandwidth the way conventional transformers do. The ZEROs have impressive bandwidth - 2Hz to 2MHz, which is beyond most amps made. This is because they have a very low t... | |
| Tonearm mount on the plinth or on Pillar ? In a typical cutting lathe is the cutting arm mounted on the same plinth as the platter or is it on a platform ?The lathe platter and the cutter are mounted rigidly in the same assembly. Ours is made of cast-machined stainless! That assembly in tu... | |
| Determining current flow to install "audiophile" fuses. PS for Atmasphere: time to catch up to the 21st century. A lot has happened in those 27 years. We have quantum chips and everything! ;-)Yes, the quantum chips are a hoax. | |
| Speltz Zero Autoformer with Tenor OTL 75 It works quite well if you are trying to drive a lower impedance with your amplifiers. There is no loss of speed- the ZEROs have bandwidth to about 2 MHz, which is more bandwidth than most amps made. People ask me if the ZEROs obliterate the OTL-n... | |
| Dual Differential / Balanced? Thanks kirkus for your comments.Bill Whitlock's paper is excellent. I like the Rane page on balanced operation (http://www.rane.com/note110.html) as a succinct description of the balanced line standard, AES file 48. | |
| Determining current flow to install "audiophile" fuses. I’m going to develop and market an audiophile grade bi-directional fuse and nip this thing in the bud. With this product, IT WON’T MATTER AND THERE WILL BE NO UNCERTAINTY! :-)We've already got one!27 years ago we recognized that fuses can affect... | |
| WHAT'S THE DEAL WITH WATTS? A few notes...First, efficiency of 93 db is a moderate efficiency. Its likely though that these speakers are really rated by sensitivity instead of efficiency, if so then the actual efficiency if the speaker is 4 ohms will be 90 db. I just noticed... | |
| Dual Differential / Balanced? I can see a problem with fully balanced audio amp design that has no reference to ground. Both outputs can be floating together since without output current or voltage difference feedback won't react to that. It needs ground reference somew... | |
| Dual Differential / Balanced? I won’t even comment on the issue of instability because you can find it in any FAQ/primer on fully balanced design, but it appears that you question my notion that connection with XLR cables is not always the best. Experience of many people on th... |
