| Thought on OTL tube amps Its very difficult to compete with OTL in harmonic richness for any solid state amplifier. I admit it. We are doing our best but its difficult.I went down a similar path 25 years ago. It got a lot easier when we got rid of the feedback. All I can ... | |
| Thought on OTL tube amps negative feedback....to control speakers even better.Negative feedback cannot be used to control speakers. It can only be used to control amplifiers. The idea that it helps with speaker control is part of the myth of damping factor, a subject that... | |
| Thought on OTL tube amps Sure. The issue is this: there are human hearing perceptual rules and there are the specs that we see on paper, and surprisingly they have very little to do with each other. So if you design your amp to look good on paper, it at best will sound li... | |
| Thought on OTL tube amps Here is the issue with OTLs and speaker loads. There are two major concerns. The first is this:http://www.atma-sphere.com/papers/paradigm_paper2.htmlIn short you want a speaker that is designed for tubes. The second is that the smaller you make th... | |
| Thought on OTL tube amps Jallen's comment above reflects a popular myth.OTLs can be as reliable and safe as any other amplifier. Its all in the design. The only OTL design out there that really did have issues is the one that has generated a lot of the mythology around OT... | |
| A major disconnect between the audiophile magazine If you are looking to compare older gear with new stuff, I recommend making sure the power supplies and the like are up to snuff with good filter capacitors. PRat, FWIW, is something you can design for but has its own price that it exacts of the d... | |
| Wilson audio Maxx best amp match??? The Wilson speakers have always been friendly to tubes; if you look at what Wilson employees are using, expect to see tubes.Its a good idea to have an amplifier with some power behind it. The larger ARCs, CAT, Manley as well as our own amplifiers ... | |
| Importance of Damping Factor and Current for amps This is not a universal truth by any means! If the speaker is over-damped by the amplifier, you will get **less** bass and no definition!Some speakers want almost no damping and others need some; no known speaker needs over 20:1.There are two desi... | |
| Anyone compared BAT Rex vs. Atmasphere MP-1? Raquel, I think with older tubes the quote might be accurate. But with modern signal tubes, particularly low level miniatures, there is a phenomena of grid contamination that has to do with the inclusion of contaminates during the assembly process... | |
| how to clean brushed aluminum faceplate? No, diamonds are one of the few materials harder than an anodized finish. When you brush your hand or fingernail against a brushed anodized surface, the ridges in the surfaces will remove skin or fingernail cells and material, leaving something th... | |
| Easy tonearm replacement for Empire 598? Mosin, I was mostly interested in an oil that would stand up for years without loosing much to the air due to neglect. Motor oil works fine too but to not last as long as it seems more volatile. We are talking about years here... | |
| Anyone compared BAT Rex vs. Atmasphere MP-1? Raquel, yes, those old 'chrome dome' tubes are pretty impressive- I've seen them as original parts in equipment that is over 50 years old, still testing as strong as new tubes. We have seen them go over 50,000 hours in our stuff and I would not be... | |
| Anyone compared BAT Rex vs. Atmasphere MP-1? The preamp is designed for 24/7 operation. IMO you get better bang for the buck when the preamp is operated when you are playing music, rather than using up the tubes while you are at work or asleep in bed.It warms up quickly, much faster than in ... | |
| Easy tonearm replacement for Empire 598? We use Dextron automatic transmission fluid. A couple of drops is all you need. | |
| TriPlanar Tips Just a FWIW: although the Triplanar arm is damped, its not a good idea to go tapping on it and especially other arms to ascertain the damping qualities!The reason is that most arms have very fragile bearings, especially if they use cones or points... |
